Ultrafiltration water purifiers are a common family water purification equipment. They remove large particles and some organic matter, microorganisms, etc., from water through the filtration system, while retaining minerals and trace elements in water. Ultrafiltration water purifiers mainly rely on the ultrafiltration membrane, which can effectively remove impurities such as bacteria, viruses, rust, and suspended matter from water, but has limited effect on heavy metals and pesticide residues in water. Next, let's learn about the types of filter cores of ultrafiltration water purifiers and their respective functions.

1. Conventional filter core

Function: Conventional filter cores usually contain activated carbon filter cores, which mainly function to adsorb odors, colors, and some organic matter in water. Activated carbon has strong adsorption properties and can effectively remove residual chlorine, odors, and discolorations from water.

2. Ceramic filter core

Function: Ceramic filter cores are made of high-quality natural ceramic materials, which have strong adsorption capacity and can effectively remove residual chlorine, organic matter, bacteria, viruses, etc. from water. Ceramic filter cores can also remove impurities such as rust and suspended matter, improving the taste of water. Ceramic filter cores have certain filtration accuracy, but their filtration effect is not as good as that of the ultrafiltration membrane filter core.

3. Ultrafiltration membrane filter core

Function: The ultrafiltration membrane filter core is the core component of the ultrafiltration water purifier, which can filter out impurities such as bacteria, viruses, rust, and suspended matter from water, while retaining minerals and trace elements. The pore size of the ultrafiltration membrane filter core is usually around 0.001 micrometers, which can effectively remove large molecular organic matter, bacteria, viruses, etc., from water, but has limited effect on heavy metals and pesticide residues in water.

4. Reverse osmosis membrane filter core

Function: The reverse osmosis membrane filter core has a higher filtration accuracy, with a pore size usually around 0.0001 micrometers, which can remove harmful substances such as bacteria, viruses, heavy metals, pesticide residues from water, while retaining minerals and trace elements. The reverse osmosis membrane filter core can effectively remove impurities in water, but it has some impact on the taste of water and mineral content, and it may be necessary to add mineral supplements after use.

5. Nanofiltration membrane filter core

Function: The filtration accuracy of the nanofiltration membrane filter core is between ultrafiltration membrane and reverse osmosis membrane, usually between 0.0001-0.00001 micrometers, which can remove harmful substances such as bacteria, viruses, heavy metals, pesticide residues from water, while retaining minerals and trace elements in water. The filtration effect of the nanofiltration membrane filter core is similar to that of the reverse osmosis membrane filter core, but has less impact on the taste of water and mineral content.

Summary

Ultrafiltration water purifiers have various types of filter cores, each with its unique functions and application scenarios. When choosing an ultrafiltration water purifier, you can select the appropriate filter core according to your family's water quality and personal needs. Generally, for families with relatively good water quality and no high requirements for water taste, conventional filter cores or ceramic filter cores can be considered; for families with poor water quality or high requirements for water taste, it is recommended to choose ultrafiltration membrane filter cores or reverse osmosis membrane filter cores.
