Is the water filtered by a reverse osmosis water purifier "purified water" or "mineral water"?When purchasing household drinking water equipment, many consumers struggle with the question: what type of water is filtered by a RO water purifiers? Is it "mineral water" containing minerals needed by the human body, or extremely pure "purified water"? Will long-term consumption have any health effects? As a company deeply rooted in the water purification industry, Aibote adheres to the production philosophy of intelligence, informatization, and automation.
To understand the nature of the water, we must first look at its filtration precision. The core component of a reverse osmosis water purifier (RO machine) is the RO reverse osmosis membrane. This membrane has a pore size of only 0.0001 microns.
Filtration Effect: It can effectively intercept heavy metals, bacteria, viruses, antibiotics, and pesticide residues in the water.
Mineral Fate: Because the diameter of mineral ions such as calcium, magnesium, and potassium is larger than that of water ions, they are also intercepted when passing through the RO membrane and discharged with the "wastewater." Therefore, the water filtered by a reverse osmosis water purifier is essentially pure water (H₂O).
Many people worry that drinking pure water long-term will lead to a lack of trace elements, but this is a common misconception.
Nutritional Source: Nutritionists generally agree that the main way the human body obtains minerals is through daily diet (vegetables, meat, eggs, dairy, etc.), not drinking water. For example, the calcium in a glass of milk may be equivalent to that in hundreds of liters of mineral water.
Core Purpose of Drinking Water: The primary purpose of drinking water is to replenish fluids. Given the current environment where tap water networks may suffer from secondary pollution and excessive heavy metals, the "ultimate safety" provided by reverse osmosis water purifiers has far greater health value than trace minerals.
Comparison: So-called "mineral water" usually refers to natural underground mineral springs. While ordinary ultrafiltration water purifiers retain minerals, they cannot remove heavy metals and limescale. In areas with high water hardness, the experience is far inferior to that of an RO machine.
With the improvement of living standards, RO water purifiers have become a standard feature in modern family kitchens. Their advantages go beyond just "purity":
Sweet taste: Removing residual chlorine and odors results in a refreshing taste, better preserving the original flavor of tea and coffee.
Prevents limescale buildup: Reverse osmosis technology completely solves the problem of limescale buildup in kettles, extending the lifespan of small appliances such as humidifiers and coffee makers.
Convenient direct drinking: Modern high-flow RO water purifiers (such as 800G and 1000G) provide instant filtration and drinking water, eliminating waiting time.
When selecting a product, in addition to focusing on the "pure water" attribute, you should also pay attention to the following three core indicators:
Reverse osmosis water purifiers produce standard pure water. It establishes a solid drinking water safety barrier for modern families. For families seeking a healthy, safe, and scale-free lifestyle, choosing a high-quality reverse osmosis water purifier is a wise decision.

Can UF water purifiers remove viruses?In today's pursuit of a high-quality life, home water purification equipment has become standard equipment for many families. Faced with a dazzling array of choices on the market, UF water purifiers (ultrafiltration water purifiers) are widely favored due to their characteristics of requiring no electricity, producing no wastewater, and retaining minerals.
The core component of a UF water purifier is an ultrafiltration membrane. The pore size of this membrane is typically between 0.01 and 0.1 micrometers. Through the principle of physical sieving, it can effectively intercept large molecules in the water.
The answer is direct: a high-quality UF water purifier can filter out the vast majority of bacteria, but the removal rate of viruses depends on the size of the virus and the precision of the filter membrane.
Bacteria: Their diameter is generally between 0.5 and 5 micrometers. The pore size of the filter membrane in a UF water purifier (approximately 0.01 micrometers) is much smaller than that of bacteria, therefore the removal rate is extremely high.
Viruses: Much smaller than bacteria, typically between 0.02 and 0.4 micrometers in diameter.
For viruses larger than 0.01 micrometers in diameter, high-quality ultrafiltration membranes can achieve physical interception.
However, some extremely small viruses (such as norovirus, certain strains of hepatitis A virus, etc.) may theoretically penetrate ultrafiltration membranes with larger pore sizes.
Expert Tip: Although ultrafiltration membranes can intercept most microorganisms, if the local water source has a serious risk of viral contamination, relying solely on ultrafiltration technology may not be sufficient. It is generally recommended to combine it with an ultraviolet (UV) germicidal lamp or choose an RO reverse osmosis water purifier.
Understanding the differences between UF and RO water purifiers is important when purchasing. The following is a simplified comparative analysis:
Filtration Accuracy and Safety: UF water purifiers have an accuracy of approximately 0.01 micrometers, intercepting bacteria and large molecular viruses; RO machines have an accuracy of 0.0001 micrometers, filtering out almost all impurities, including extremely small viruses and heavy metals.
Mineral Retention: A major advantage of UF water purifiers is their ability to retain beneficial natural minerals in the water; while RO machines produce pure water through thorough filtration, containing virtually no minerals.
Energy Consumption and Environmental Friendliness: UF water purifiers utilize tap water pressure for physical filtration, requiring no electricity and producing no wastewater; RO machines require electricity for pressurization and discharge a certain proportion of wastewater.
Suitable Environment: UF water purifiers are suitable for urban areas with good tap water quality, meeting daily drinking water needs; if there is a high level of limescale or a risk of heavy metal contamination, an RO machine is recommended.
If you appreciate the mineral retention properties of UF water purifiers but are concerned about microbial risks, consider the following optimization options:
Choose a reputable brand: High-quality brands have more consistent ultrafiltration membrane fibers, more uniform pore size distribution, and better retention performance. For example, Aibote, founded in 2005, is a manufacturer and solution provider of residential and commercial water purification products.
Regular filter replacement: Ultrafiltration membranes trap a large amount of impurities during use; failure to replace them regularly can lead to bacterial growth and even "secondary pollution."
Multi-stage filtration systems: Choosing a system with an activated carbon filter not only improves taste but also adsorbs som

Is Drinking Reverse Osmosis Water Healthy?With increasing public awareness of drinking water safety, reverse osmosis (RO) water purifiers have gradually become a standard appliance in many households. However, the discussion about whether long-term consumption of reverse osmosis water is healthy has never stopped.
Reverse osmosis (RO) is a high-precision water treatment technology. Reverse Osmosis Water Purifier systems use a core component—the RO membrane—to remove heavy metals, bacteria, viruses, pesticide residues, and inorganic salts from tap water through pressure differences.
Because the pore size of the RO membrane is extremely small, the resulting water contains almost no impurities and is therefore often referred to as “pure water.”
In areas with poor water quality or contaminated groundwater, a Reverse Osmosis Water Purifier acts as a powerful barrier. It effectively removes excessive levels of harmful substances such as lead, cadmium, and mercury, helping to prevent long-term chemical damage to the human body.
By removing calcium and magnesium ions that cause water hardness, as well as residual chlorine, reverse osmosis water tastes purer and smoother. This makes it ideal for brewing specialty coffee or high-quality tea, allowing the original flavors of beverages to shine.
Using reverse osmosis water eliminates scale buildup in kettles and humidifiers, helping extend the lifespan of household appliances and reducing maintenance costs.
A common concern is that while reverse osmosis removes harmful substances, it also removes beneficial minerals such as calcium, magnesium, and potassium. From a scientific perspective:
Children in growth stages or elderly individuals with limited diets should ensure sufficient mineral intake through diverse foods rather than relying solely on drinking water.
If you plan to install a Reverse Osmosis Water Purifier, consider the following points to ensure safe and healthy drinking water:
Drinking reverse osmosis water is generally beneficial to health, especially in areas with potential water pollution risks. While it removes some minerals, these can be easily compensated through a balanced daily diet. For most people, the safety advantages of reverse osmosis water far outweigh its limitations.

What are the steps involved in the water purification process of a water purifier?In today's pursuit of a healthy life, water purifiers have become an important device for many families to ensure drinking water safety. What kind of "transformation" does water undergo to become so pure after passing through a water purifier?
The core value of a high-efficiency water purifier lies in its precisely designed filtration system. We will take a water purifier using CP+RO+CB filtration technology as an example to analyze its purification steps in detail. This system consists of three main lines of defense:
The composite pre-filter (CP) typically integrates a polypropylene melt-blown (PP cotton) filter and/or activated carbon granules. In this stage, the raw water undergoes the following treatment:
Reverse osmosis (RO) is widely recognized as the most crucial and essential purification technology in modern water purifier systems. The RO membrane has extremely small pores, only about 0.0001 microns. Water molecules are forced through the RO membrane under pressure, while the vast majority of impurities, pollutants, heavy metals, bacteria, and viruses are retained.
The post-carbon filter (CB) is the final "beautifier" before the purified water enters the drinking water stage.
When focusing on the purification effect of a water purifier, water efficiency is also an important indicator.
This water purifier has a purification/discharge ratio of 2:1, meaning that for every 2 parts of purified water produced, only 1 part of wastewater is discharged. This is an excellent water efficiency ratio, indicating that the water purifier can efficiently produce pure water while maximizing water conservation and reducing household water costs.
Choosing the right water purifier hinges on focusing on its filtration system configuration, water efficiency performance, and filter replacement cycle:
Through the multi-stage filtration of the CP+RO+CB system, your drinking water is thoroughly purified, allowing you and your family to enjoy safe and healthy pure water.
A: This refers to the three main filtration stages used in this water purifier: CP (composite filter element, used for preliminary filtration and adsorption), RO (reverse osmosis filter element, used for core deep purification, removing heavy metals, bacteria, etc.), and CB (post-activated carbon filter element, used to improve the taste of pure water).
A: The RO membrane is the core of the water purifier, mainly removing heavy metal ions, scale, bacteria, viruses, and almost all dissolved solids from the water, forming the basis for achieving high-standard pure water.
A: This ratio is an indicator of a water purifier's water efficiency. A 2:1 ratio means that for every 2 parts of purified water produced, only 1 part of wastewater is discharged, which falls within the high water efficiency range and helps conserve water resources.
A: Its main function is as the final step, further adsorbing any trace amounts of residual odor in the water, thereby improving the taste and making drinking water sweeter.
A: The replacement cycle for the filter cartridges depends on the water quality, usage frequency, and the type of filter cartridge (such as PP cotton, activated carbon, RO membrane). Generally, it needs to be replaced regularly according to the intervals recommended in the product manual, especially for the RO membrane, to ensure the continuous and efficient operation of the water purifier.

What is RO technology in water purifiers?With modern families increasingly demanding higher quality drinking water, RO water purifiers have become the preferred choice for many. But what exactly is RO technology? Why can it provide such high-standard purified water?
RO technology originated from seawater desalination and is a high-precision, high-efficiency water treatment method.
The principle of reverse osmosis is the opposite of the familiar natural osmosis phenomenon. In natural osmosis, water molecules flow from the low-concentration solution side to the high-concentration solution side through a semi-permeable membrane. Reverse osmosis technology, however, applies pressure higher than the natural osmotic pressure to the raw water, forcing water molecules to flow in the opposite direction through an extremely precise semi-permeable membrane.
Core component: RO membrane (reverse osmosis membrane).
Membrane pore size: The pore size of the RO membrane is as small as approximately 0.0001 micrometers, a size that allows almost only water molecules to pass through.
The extremely fine pore size of RO membranes allows them to effectively intercept the vast majority of impurities in water, including:
Water filtered through an RO membrane is almost entirely pure water molecules, hence the term "pure water," which is key to the high-quality drinking water provided by RO water purifiers.
A high-quality RO water purifier typically employs a multi-stage filtration system to ensure the RO membrane is protected and performs optimally. A standard process usually includes the following steps:
Stage 1 (PP cotton): Pre-filtration, removing large particles such as sediment, rust, and insect eggs.
Second/Third Stage (Granular Activated Carbon/Compressed Activated Carbon): Adsorbs residual chlorine, odors, and some organic matter in the water, improving taste and protecting the RO membrane.
Fourth Stage (RO Reverse Osmosis Membrane): Core filtration, removing heavy metals, bacteria, viruses, and most dissolved solids from the water. This is the key step that distinguishes ordinary water purifiers from RO water purifiers.
Fifth Stage (Post-Activated Carbon): Further adsorbs any remaining odors, adjusting the taste of the water to make drinking water sweeter and more palatable.
Extremely High Purity: Effectively handles complex water quality issues, providing almost pure water. For families with poor water quality or infants, RO water purifiers provide a safety guarantee.
Improved Taste: Effectively removes odors and chlorine, resulting in better-tasting drinking water.
Safe and Reliable: Eliminates potential health risks in drinking water, such as heavy metal and microbial contamination.
Choosing a highly efficient and reliable RO water purifier is a wise choice for modern families seeking a healthy and high-quality drinking water experience. It's not just a home appliance; it's a commitment to your family's health.
RO (Reverse Osmosis) technology is a method of filtration that applies pressure to raw water, forcing water molecules to pass through a semi-permeable membrane with a pore size of approximately 0.0001 micrometers.
The RO membrane is the core filtration component. It effectively intercepts most impurities in the water, including heavy metals, bacteria, viruses, limescale (calcium and magnesium ions), and pesticide residues.
It uses pressure higher than the natural osmotic pressure to force water molecules to flow backward from the high-concentration side (raw water) to the low-concentration side (pure water), the opposite of natural osmosis.
High-quality RO water purifiers typically use a five-stage filtration system, with the core RO reverse osmosis membrane being the fourth stage.
Because after RO membrane filtration, almost only pure water molecules remain in the water, while most dissolved solids and impurities are removed.
Therefore, RO water purifiers are a highly recommended solution for families seeking safe and high-quality drinking water.

What is the working principle of a UF water purifier?In today's pursuit of a healthy lifestyle, the quality of drinking water is receiving increasing attention from families. Among numerous water purification products, UF water purifier (ultrafiltration water purifiers) have become the first choice for many families due to their high-efficiency filtration performance and the advantage of not requiring electricity.
The core component of a UF water purifier is the ultrafiltration membrane. To understand its working principle, it's essential to understand the structure and characteristics of this filter element:
Precise pore size: The ultrafiltration membrane is a microporous filtration medium with a pore size between 0.01 micrometers and 0.1 micrometers. This size falls between microfiltration and nanofiltration.
Physical sieving: The water purification process of a UF water purifier primarily relies on physical "sieving." When tap water flows under pressure (usually the pressure of tap water is sufficient) through the surface of an ultrafiltration membrane, large molecules such as particles, bacteria, colloids, rust, and sediment with diameters larger than the membrane pores are trapped on the membrane surface, while water molecules, dissolved salts (mineral ions), and some small molecules can pass through smoothly.
A complete UF water purifier is not just a single ultrafiltration membrane; it typically consists of multiple filter stages working together to achieve efficient water purification:
Primary Filtration (PP cotton): Responsible for removing larger, visible particles such as sediment and rust, protecting subsequent filter stages.
Adsorption Filtration (Activated Carbon): Usually uses granular or compressed activated carbon, which removes discoloration, odors, residual chlorine, and some organic pollutants through its powerful adsorption capacity, key to improving taste.
Core Purification (Ultrafiltration Membrane): This is the core of the UF water purifier's deep water purification process. It intercepts bacteria, viruses, colloids, and microorganisms in the water, significantly improving water safety.
Post-treatment (post-activated carbon): Further improves the taste of the water, making the purified water sweeter and more palatable.
The working principle of a UF water purifier is to use the synergistic effect of these multiple filter stages to filter the water layer by layer, ultimately providing clean water that can be drunk directly.
Having understood the working principle of UF water purifiers, let's look at why they are favored by the market:
Mineral Retention: Compared to RO reverse osmosis technology, ultrafiltration membranes allow mineral ions in the water to pass through, which allows UF water purifiers to retain beneficial natural trace elements while providing safe drinking water.
Low Operating Costs: Most UF water purifiers are driven by water pressure and do not require electricity, saving energy and avoiding additional electricity costs.
High Water Output: Ultrafiltration membranes typically have a high flux and fast water output, making them ideal for families that require large amounts of domestic water (such as washing vegetables and rinsing rice in the kitchen).
Therefore, UF water purifiers are an economical and efficient choice for home water purification, especially suitable for families with good source water quality who wish to retain minerals in the water.
No matter how high-quality a home water purifier is, it requires regular maintenance. The filter cartridges in a UF water purifier gradually become saturated with use, resulting in decreased filtration efficiency, thus requiring regular replacement.
Pre-filter cartridges (PP cotton, activated carbon): Generally recommended to be replaced every 3–6 months to ensure water quality and protect the core ultrafiltration membrane.
Ultrafiltration membrane: As a core component, the replacement cycle is relatively long, typically 1–3 years, depending on the source water quality and usage.
Regular filter cartridge replacement is key to ensuring the UF water purifier continues to provide high-quality water purification.
UF water purifiers retain minerals and produce zero wastewater, while RO water purifiers remove almost all impurities (including minerals) and produce wastewater.
Traditional UF water purifiers cannot effectively remove dissolved heavy metal ions and require the use of other technologies (such as RO or ion exchange) to achieve this.
No, UF water purifiers rely on direct-flow water pressure filtration and do not produce wastewater.
The pre-filter cartridge needs to be replaced every 3–6 months, and the core ultrafiltration membrane usually needs to be replaced every 1–3 years depending on water quality and usage.
Yes, water purified by a UF water purifier can meet direct drinking standards, but if the source water quality is poor, it is recommended to boil it for safety.

Must Water Purifiers Use Reverse Osmosis Technology?As people increasingly prioritize drinking water safety, household water purification equipment has transformed from an "optional" to a "necessity." However, a common question arises when consumers are choosing a water purifier: must it use reverse osmosis technology to obtain high-quality drinking water?
Reverse osmosis (RO) water purifiers are among the most widely used and efficient water purification devices on the market. They use semi-permeable membrane technology to effectively separate water molecules from impurities (including heavy metals, bacteria, viruses, and scale) under pressure.
This filtration method significantly improves water purity, producing drinking water that is close to pure water, meeting the family's demand for high-standard healthy drinking water.
This does not mean that other technologies are unimportant. Mainstream non-RO technologies on the market, such as ultrafiltration (UF), nanofiltration (NF), and activated carbon filtration, each have their own value:
Ultrafiltration (UF) water purifiers: Primarily remove bacteria, colloids, and particulate matter, while retaining some beneficial minerals.
Activated carbon filtration: Effective at adsorbing residual chlorine, odors, and some organic matter, improving the taste of water.
These technologies can be used supplementarily in specific scenarios, but for deep purification and comprehensive impurity removal, reverse osmosis water purifiers undoubtedly have a more significant effect.
Not all households need to use reverse osmosis water purifiers, but RO technology shows significant advantages in the following situations:
When the raw water quality is poor: When the tap water has a high TDS (Total Dissolved Solids) value or contains contaminants such as heavy metals and nitrites, reverse osmosis water purifiers can more effectively ensure drinking water safety.
When there are infants or elderly people in the family: For family members with high water quality requirements, purer water is more conducive to health.
For families sensitive to limescale: Reverse osmosis membranes effectively remove calcium and magnesium ions, reducing limescale formation at the source and protecting appliances such as coffee makers and kettles.
When purchasing, consumers should not only consider price or advertising gimmicks, but also their own water usage habits. If the local water quality is good and you want to retain minerals, you can install a reverse osmosis water purifier in the kitchen's drinking water area, while using ultrafiltration systems or pre-filters at other water points throughout the house, achieving both zoned purification and energy savings.
Whether reverse osmosis technology is necessary depends on your family's water needs and local water quality:
Poor water quality or a desire for high-purity drinking water – a reverse osmosis water purifier is more suitable;
Good water quality or a desire to retain minerals – an ultrafiltration or composite filtration system can be used.
Regardless of the chosen solution, a reverse osmosis water purifier is one of the key devices for achieving deep purification and ensuring safe drinking water. Only by properly combining different filtration technologies can you truly achieve a healthy, safe, and comfortable home water experience.

Is UF Suitable for Whole-House Filtration?With people's pursuit of a high-quality life, the safety and health of household water have become important indicators of living standards. Against this backdrop, water treatment technology has gradually evolved from traditional single-drinking water purification to comprehensive improvement of whole-house water quality. UF water purifiers (ultrafiltration water purifiers), with their advantages of high efficiency in intercepting and retaining minerals, are attracting increasing attention from families, leading people to consider whether they are suitable for whole-house filtration.
The core of UF water purifiers lies in their use of ultrafiltration membrane technology. This is a highly efficient physical filtration method, and its key lies in the precise control of pore size.
Precise Filtration Range: The pore size of ultrafiltration membranes is typically controlled between 0.01 and 0.1 microns.
Highly Efficient Contaminant Interception: This pore size allows it to effectively intercept bacteria, viruses, large organic molecules, colloids, and visible suspended impurities in the water.
Retaining Beneficial Minerals: Unlike deep purification technologies such as RO (reverse osmosis), UF water purifiers are characterized by their ability to retain beneficial minerals, which is especially important for families seeking "soft, healthy water."
Environmentally Friendly and Water-Saving: UF water purifiers produce almost no wastewater during the filtration process, resulting in high water utilization, energy efficiency, and rapid water output, better meeting the immediate water needs of the entire household.
To determine whether "UF is suitable for whole-house filtration," it's crucial to clarify the specific needs for "whole-house filtration."
Domestic Water Purification: UF water purifiers are often used as a core component of secondary or tertiary filtration in whole-house water purification systems. They effectively improve water quality at various points of use in the home, such as for showering and laundry, significantly reducing the impact of impurities on skin, hair, and clothing.
Deep Drinking Water Standards Considerations: It's important to note that UF water purifiers, relying solely on ultrafiltration technology, cannot completely remove heavy metal ions and soluble salts (TDS) from water. Therefore, if the local water TDS value is high, or if the user has higher purification requirements for drinking water (such as removal of chemical contaminants), it should be used in conjunction with other filter cartridges.
To better understand the positioning of UF, it can be compared with mainstream water purification technologies based on the following key performance indicators:
Filtration Accuracy Comparison: UF water purifiers have a pore size of approximately 0.01-0.1 microns, making them outstanding in removing bacteria and viruses. In contrast, RO water purifiers have a smaller pore size (approximately 0.0001 microns), removing almost all dissolved solids.
Mineral Retention vs. Wastewater Discharge: UF technology retains minerals in the water and produces virtually no wastewater; RO technology, on the other hand, removes most minerals and generates a certain amount of wastewater.
Application Focus: UF water purifiers are more suitable for purifying and enhancing domestic water, while RO water purifiers are more suitable for scenarios with higher requirements for drinking water purity. A standalone activated carbon filter layer mainly relies on adsorption and has limited ability to remove heavy metals and ions.
UF water purifiers are an ideal choice for household water purification, effectively improving the cleanliness and user experience of daily water use.
However, to meet the multi-level water quality needs of the entire house, a combined water purification solution is recommended: for example, using a UF water purifier as a basic protective layer in the main water system (or secondary filtration), while simultaneously installing an RO system in the kitchen to meet the needs of deep purification of drinking water. Only by scientifically configuring the system based on local water quality conditions and family water usage habits can true health and safety of water throughout the house be guaranteed.

How to Choose a Water Purifier or Filter?In today's pursuit of a high-quality life, drinking water safety and health have become increasingly important core issues. Faced with a dazzling array of water purifiers and filters on the market, consumers need clear guidance to make the most suitable choice for their needs.
The first step in choosing a water filter is to understand the water quality in your area.
Tap Water: If your tap water meets national drinking water standards, but you still want to remove residual chlorine and improve taste, then an ultrafiltration or activated carbon filter may be a cost-effective option.
High Hardness/Specific Contaminants: If the local water is hard (high in impurities), or there are concerns about excessive levels of specific contaminants such as heavy metals and bacteria, then deeper filtration is needed. Reverse osmosis (RO) water purifiers are currently the best choice for treatment effectiveness.
Tip: It is recommended that users purchase a water quality testing kit or consult their local water authority to determine the water hardness and main contaminants, laying the foundation for choosing the appropriate filtration technology.
Water purifiers on the market primarily rely on different filtration technologies to achieve their purification goals. Understanding these technologies is key to making the right choice:
Its main function is to adsorb residual chlorine, discoloration, and odors. It's a common method for improving the taste of drinking water and is often used in pre-filtration. Its advantage is its low cost, but it cannot effectively remove limescale or bacteria.
This filtration technology can effectively remove bacteria, colloids, and most large organic molecules, suitable for basic drinking water purification. Its advantages are fast water output and the retention of beneficial minerals in the water.
This is currently the most thorough water purification technology, capable of removing almost all impurities such as bacteria, viruses, heavy metals, and limescale. It's suitable for families seeking the purest water. The disadvantages are the potential loss of some minerals and the generation of some wastewater.
For families seeking the purest water, RO water purifiers are currently recognized as the main force in water purification; while for users who prioritize convenience and the retention of minerals, high-quality ultrafiltration water purifiers are also a good solution.
The long-term operating cost of any water filter is closely related to the frequency and price of filter replacements.
Check the Rated Total Water Capacity (TLW): This is an important indicator of filter lifespan. A higher TLW means less frequent replacements.
Understand Filter Structure: RO water purifiers typically use multi-stage filters (such as PP cotton, activated carbon, and RO membrane), requiring maintenance at each stage. Some water filters are designed with integrated filters, making replacement more convenient, but the cost may be slightly higher.
Original Manufacturer Consumables: To ensure the stability of filtration technology and water quality safety, it is recommended to prioritize original manufacturer or officially certified filter cartridges for replacement.
The installation location and water outlet method of the water purifier/filter also affect the daily user experience:
Under-sink type: Saves countertop space, suitable for families prioritizing aesthetics, usually requires professional installation.

Which water purifier is most effective?Drinking water safety is a matter of health. Faced with a dazzling array of water purifiers on the market, consumers inevitably ask, "Which water purifier is most effective?" Aibote, as a manufacturer deeply rooted in the residential and commercial water purification product field, provides a solid foundation for the effectiveness of its high-quality water purification equipment through its intelligent, information-based, and automated production philosophy.
Before discussing the effectiveness of water purification technology, we must recognize that the performance of a water purifier is highly dependent on its manufacturing process.
Aibote, with its fully automated production lines and high-precision equipment, and the introduction of four main systems—PLM, ERP, SRM, and APS—as well as MES and WMS systems, has achieved lean production and end-to-end quality control. This intelligent production system ensures that regardless of the water purification technology used, the final delivered water purification equipment achieves industry-leading levels in precision and durability.
Manufacturers with strong manufacturing backgrounds can guarantee zero error in key components (such as filter cartridge interfaces and seals), thereby maximizing the efficiency of core water purification technologies such as RO reverse osmosis.
The effectiveness of a water purifier hinges on its purification technology. Different technologies correspond to different filtration precisions and applicable scenarios:
These two technologies are primarily used for preliminary water purification.
Ultrafiltration (filtration precision up to 1 nanometer to 0.1 micrometer) effectively removes sediment, rust, suspended solids, and most bacteria. They are simple to operate and do not produce wastewater, but cannot remove heavy metal ions and inorganic salts from the water.
Between ultrafiltration and RO reverse osmosis, with even smaller pore sizes, it can effectively remove hardness components (such as calcium and magnesium ions), odors, color, and some organic matter from the water.
This is currently recognized as one of the most effective deep water purification technologies. RO membranes have extremely small pore sizes (typically less than 0.0001 micrometers), capable of intercepting most contaminants such as bacteria, viruses, heavy metal ions, and dissolved solids, producing drinking water that is close to pure water.
From the perspective of removing the vast majority of contaminants from water, water purifiers equipped with RO reverse osmosis technology are considered the most effective choice. They provide families with high-quality drinking water, especially in areas with unstable tap water quality or concerns about heavy metals.
However, RO reverse osmosis water purifiers also have some characteristics:
While producing pure water, some contaminants are discharged with the wastewater.
The produced water is close to pure water, and some users choose water purifiers with "mineralization filters" to improve the taste.
The "effectiveness" of a water purifier is relative and needs to be judged based on your actual needs:

Which water purifier is suitable for home use?During the water supply process, tap water may be contaminated by secondary contamination, such as rust, silt, and bacteria caused by aging pipe networks. Furthermore, potential threats such as residual chlorine, heavy metals, and organic pollutants in the water require professional water purification technology to remove. Installing a home water purifier can effectively improve the taste of drinking water, remove odors, and more importantly, deeply purify the water, making the water safer and healthier for you and your family.
Understanding the working principles and advantages of different water purifiers is the first step in purchasing one. Currently, the mainstream types of home water purifiers are as follows:
Features: It primarily filters large molecules such as rust, silt, colloids, and bacteria from water using an ultrafiltration membrane. It retains minerals in the water, requires no electricity, and delivers water quickly.
Suitable for: Families with low water quality requirements who primarily want to remove impurities and bacteria while preserving natural minerals.
Core Technology: RO membrane (reverse osmosis membrane), with a filtration accuracy of up to 0.0001 micron, effectively removes almost all impurities from water, including heavy metal ions, pesticide residues, bacteria, viruses, and more, resulting in pure water.
Features: Provides the most thorough purification, but typically requires electricity, produces wastewater, and has relatively high filter element replacement costs.
Suitable for: Households seeking extremely pure water in areas with poor water quality (e.g., high TDS).
Features: Primarily used to absorb discoloration, odor, residual chlorine, and some organic matter in water. Often used as a pre- or post-filter in ultrafiltration or RO water purifiers to improve taste.
Suitable for: Used as a supplement to other water purification equipment; purification effectiveness is limited when used alone.
If your area has high water hardness or excessive levels of heavy metals, we strongly recommend choosing a reverse osmosis (RO) water purifier for more thorough purification.
If you only need to remove larger impurities, improve the taste, and retain minerals in the water, you can consider an ultrafiltration (UF) water purifier.
Pay attention to the water purifier's flow rate, usually expressed in "G" (gallons) (e.g., 400G, 600G, 800G). A higher flow rate means faster water output, which reduces waiting time when receiving water and is particularly suitable for households with peak usage or high water consumption.
Filter replacement is an ongoing expense for a home water purifier and must be factored into your budget. Understand the life expectancy and replacement prices of different filter cartridges (e.g., PP cotton, activated carbon, RO membrane) to estimate long-term maintenance costs.
The wastewater ratio (e.g., 1:1, 2:1, 3:1) is a measure of the water-saving performance of an RO water purifier. Selecting a system with a higher wastewater ratio (e.g., 3:1) means less wastewater is generated per unit of purified water, which is more environmentally friendly.
If you seek safe, healthy drinking water and want to completely remove contaminants from the water, a reverse osmosis water purifier is undoubtedly the most thorough and suitable type of water purifier on the market for home use. When choosing, be sure to consider the water flow rate and filter replacement costs to ensure that the water purifier can provide your family with high-quality water for a long time and efficiently.
Choosing a high-quality water purifier is like choosing a health guarantee. Before purchasing, it's best to understand your own water quality and then identify the most suitable water purifier for your home based on your budget and needs.
