Introduction to the types of filter elements used in water purifiers-[3M filter elements]

1. PP filter element u003cbru003e　　Pure water machine accessories PP filter element is the abbreviation of polymer material polypropylene, with a filtration accuracy of 5-100um. Because of its mesh structure, it has a super-intercepting effect on those larger particles to filter rust and sediment. the goal of. The general replacement cycle is 3-6 months. u003cbru003e　　2, activated carbon filter element u003cbru003e　　 Activated carbon is generally made of coconut shell, apricot shell, coal, and wood chips through a special process. The inside of the activated carbon is rich in pores. The surface of the pores accounts for more than 90% of the entire activated carbon area. The activated carbon is made through these pores. Absorb free residual chlorine and some other odorous substances, colloids, organic matter, and consumption by-products in the water to achieve the purpose of improving the taste of water. We generally choose coconut shell activated carbon because of its good adsorption performance, which other activated carbons cannot. Comparable. The replacement cycle of activated carbon is generally 3-6 months, depending on the local water quality. u003cbru003e　　3, KDF u003cbru003e　　KDF is a copper-zinc alloy with a golden yellow appearance. It forms a copper-zinc galvanic cell when it comes in contact with water. It absorbs toxic heavy metal pollution and achieves the purpose of removing heavy metals. u003cbru003e　　4, ultrafiltration filter element u003cbru003e　　 Filtration accuracy: 0.01um~0.1um~ u003cbru003e　　 filter and trap mud, rust, bacteria, viruses, colloids, etc., to achieve the purpose of separation, purification, separation and concentration of tap water. u003cbru003e　　5, RO filter element (reverse osmosis filter element) u003cbru003e　　 Filtration accuracy: 0.1nm u003cbru003e　　 filters salt ions and other impurities. The effluent is pure water, and reverse osmosis membrane. It is a purifier with a particularly high filtration accuracy. The filter hole is 0.1nm, which is 100 times the ultrafiltration accuracy. All ions in the water Will be intercepted by it, and the water from the household reverse osmosis pure water machine does not contain any ions. u003cbru003e　　6, activation ball u003cbru003e　　 Activated ball has four major functions: efficient bacteria production, mineralized water, activated water, and pH adjustment.
