Capillary membranes are modern filtration elements used in water treatment wherever very high contaminant separation efficiency is needed. Thanks to their design and the use of the capillary phenomenon, they help improve water safety and quality in both household and specialist applications.
In this category, you will find capillary membranes for water filters, designed for very precise filtration and supporting the ultrafiltration process. Their key advantages are high operating precision, no water rejection, compact size, and easy operation. To work properly, they require the use of pre-filters, which protect the membrane from clogging. The offer includes products from Aquafilter, Aquaphor and Bluefilters.
Introduction to capillary membrane technology
Capillary membranes are an important part of modern water filtration technology. They offer an effective method of removing contaminants at the microscopic level, helping to obtain safer and cleaner water both at home and in various utility applications. Their unique design allows them to separate physical, biological, and chemical contaminants, improving the overall quality of the filtered water.
Due to their very high filtration precision, capillary membranes should operate with properly selected pre-filtration. This is important because pre-filters help reduce the risk of membrane clogging and support its stable operation.
What is the capillary phenomenon?
The capillary phenomenon means the ability of a liquid to move through very narrow spaces without external assistance, and even against the force of gravity. In the case of capillary membranes, this property is used to move water through thin, porous structures that retain unwanted substances.
Thanks to microscopic pores, capillary membranes can effectively filter water while, in many applications, allowing it to retain its natural mineral composition. This is one of the features that distinguishes them from other technologies used in water treatment.
Key advantages of capillary membranes
Capillary membranes are valued both for their filtration efficiency and for the practical benefits they offer during everyday use.
- Very high filtration precision when removing contaminants at the microscopic level.
- No water rejection, which can be important for users looking for economical and convenient solutions.
- Compact size, making them easier to use in compact filtration systems.
- Easy operation and convenient use.
- Effective removal of physical, biological, and chemical contaminants according to the intended purpose of a given system.
High operating precision is a major advantage of capillary membranes, but it is also a reason to ensure proper pre-filtration. Well-selected pre-filter cartridges help extend membrane life and maintain stable operating parameters.
Where are capillary membranes used?
Capillary technology is used wherever high water filtration efficiency and the removal of fine contaminants and microorganisms are needed.
- In household installations that improve the quality of utility and drinking water.
- In under-sink filter systems and multi-stage sets.
- In places where reducing the presence of bacteria, viruses, and other microorganisms is important.
- In specialist applications such as hospitals or laboratories.
- In solutions focused on ultrafiltration.
Capillary membrane vs. osmotic membrane
Although both technologies are used in water filtration, they differ in scope of operation and typical applications. An osmotic membrane, used in reverse osmosis, focuses primarily on removing dissolved salts and other mineral compounds. This solution is often chosen when the goal is very deep water purification and improving its parameters for drinking.
A capillary membrane, on the other hand, is particularly associated with the removal of bacteria, viruses, and other microorganisms. This makes it a good choice wherever high biological filtration efficiency and convenient use without water rejection are important.

Filter with a capillary membrane – effectiveness confirmed in practice
An example of the use of this technology is the FP3-HJ-K1 Aquafilter, a 4-stage water filter with a capillary membrane. This type of solution can remove most mechanical and microbiological contaminants while also improving the overall water quality and its taste perception by the user.
This shows that a capillary membrane is not exclusively a laboratory or industrial solution. When properly selected, it can be part of a practical system used every day.
How to choose the right capillary membrane or filter?
Selecting the right solution should take into account the quality of the incoming water, the expected filtration result, and the way the system will be used. The better matched the product, the greater the chance of effective and convenient operation.
What should you pay attention to before buying?
- Incoming water quality – the more mechanical contaminants there are, the more important good pre-filtration becomes.
- Scope of expected filtration – it is worth determining whether the priority is microbiological improvement, precise filtration, or an element of a larger treatment system.
- Compatibility with the device – the membrane should fit the specific filter or housing.
- Operating conditions – frequency of use, installation location, and service method all matter.
- Specialist support – for more demanding water conditions, it is worth basing the choice on analysis results.
If you are not sure which solution will be best, it is worth consulting specialists and basing the decision on a water test. This is especially important when the filtration is meant to address a specific water quality problem in the installation.
