• Description: As we all know, the Water Filter Cartridges(KOKOELECTRIC) https://www.kokoelectric.com/product/water-filter-cartridges/ are the most important core part of the water purifier, which determines the filtering effect. In early water purification machines, filtration by a single water filter cartridges was common, but this filtration method could not completely remove pollutants in the water, and the pollutants quickly gathered, which greatly reduced the service life of the water filter cartridges and resulted in poor water purification effect. In order to avoid the above problems, the water purifier adopts a combination of four to six levels of water filter cartridges, which improves the water purification effect on the one hand and prolongs the service life of the water filtering barrels on the other. The following is an example of the combination of five-stage water filter cartridges: Primary filtration: currently, water purification machines on the market generally use 5μm PP cotton as the material of water filtration barrel to remove large particle impurities such as rust, silt, and suspended solids. Crude filtration is generally replaced every 3-6 months. Secondary filtration: Granular activated carbon filter element (UDF) integrates adsorption, filtration, interception, and catalysis, and can effectively remove chemical pollution caused by pesticides, pesticide residues, organic solvents, and other industries. But also can effectively remove organic matters, residual chlorine, and other radioactive substances in water, and has the effects of decoloring and deodorizing. The general service life is 3-6 months. Three-stage filtration: Sintered activated carbon is used as the filter element material (CTO) (PPcotton is used as the filter element material by some manufacturers), which deeply absorbs different colors, peculiar smell and residual chlorine in water and filters out fine impurities. It is used in the third stage of the water purifier and also protects the main filter element of the water purifier. Its service life is generally 3-6 months. Four-stage filtration and one main filtration water filtration barrel (if you need to know the filtration principle of various filter elements, please go to the headspace to see the professional introduction of various water purifiers) 1. Ultrafiltration membrane water filter cartridges: it is recommended to replace it once every 23 years. 2. nanofiltration membrane water filter cartridges: it is recommended to replace it every 2 years. 3. RO reverse osmosis membrane water filter cartridges: it is recommended to replace it every 2 years. 4. High-density activated carbon water filter cartridges: it is recommended to replace it once a year. Five-stage filtration: The rear activated carbon water filter tank (T33) is the last working procedure of the water purifier, which can further adsorb different color and peculiar smell in water, increase the oxygen content of purified water, and mainly improve the taste of water. Especially for water purification machines using pressure water storage tanks, the silver-loaded activated carbon filter material is recommended for the post-installed activated carbon, which can effectively absorb the peculiar smell generated by the water storage tanks, sterilize and inhibit bacteria, and ensure the safety of drinking water. The recommended service life is 12 months. Activated carbon water purifier uses ultraviolet lamps to kill fine and microorganisms. It is recommended to replace it once a year.
