What Are The Water Purifier Filter Elements
There are mainly the following types of water purifier filter elements:
PP cotton filter
1. Material and structure: polypropylene (PP) material, tubular. The fiber structure is tight, and the pore size is generally between 1 micron and 5 micron.
2. Function: – Can effectively filter the water rust, sand, eggs and other large particles of impurities. As the first filtration line of the water purifier, it protects the subsequent filter element and prolongs its service life.
3. Replacement cycle: usually 3 to 6 months, depending on water quality and water consumption.
1. Material and structure: There are mainly two kinds of granular activated carbon (GAC) and compressed activated carbon (CTO). Granular activated carbon is composed of tiny activated carbon particles and has a large specific surface area. The compressed activated carbon is to compress the activated carbon powder into a block, and the structure is more compact.
2. Function: adsorption of residual chlorine, different color, odor, organic matter, etc. – Improve the taste of water, make the water more sweet and delicious.
3. Replacement cycle: generally 6 to 12 months.
Ultrafiltration membrane filter element
1. Material and structure: made of polymer materials, such as polysulfone, polyacrylonitrile, etc. The filter element is hollow fiber, and the pore size is between 0.01 micron and 0.1 micron.
2. Function: It can filter bacteria, viruses, colloids, rust, suspended matter and other small particles of impurities in the water. Retain the beneficial minerals and trace elements in water.
3.Replacement cycle: 12 to 24 months or so.

Reverse osmosis membrane filter element
1. Material and structure: usually made of polyamide and other materials. The structure of the membrane is very fine, and the aperture is very small, generally about 0.0001 micron.
2. Function: It can almost completely remove heavy metal ions (such as lead, mercury, cadmium, etc.), bacteria, viruses, pesticide residues, organic matter and other harmful substances in the water, and the produced water is close to pure water.
3.Replacement cycle: 18 to 36 months, but it is greatly affected by water quality and water consumption.
What Are The Water Purifier Filter Elements
Rear activated carbon filter
1. Material and structure: similar to the pre-activated carbon filter, mostly granular activated carbon or compressed activated carbon.
2. Function: Further absorb the odor and color that may remain in the water, and improve the taste of the water. Ensure that the water coming out of the water purifier tastes pure and sweet.
3. Replacement cycle: similar to the pre-activated carbon filter, generally 6 to 12 months.
