In addition to ultrafiltration membrane and RO membrane, if the daily water consumption is large, such as the water purifier is installed on the main pipeline behind the main water inlet or water meter, and the water purifier is in working condition for a long time, the filter element should be replaced every three months, but at the longest, it should be replaced once every six months.
Pp cotton, activated carbon, resin, hollow fiber ultrafiltration membrane, medical stone, RO membrane, natural magnet, KDF alloy filter material, quartz sand, etc. The function of each filter element is different, for example, pp cotton generally plays the role of coarse filtration, KDF alloy filter material mainly filters heavy metal pollutants in water, and activated carbon is used to improve the taste.
Extended data 1, 100% relative humidity resistance;
2, in line with European fire classification standards;
3. Application: assembly workshop, painting workshop, surface renovation, painting room, etc.
Filter cotton products are generally used in surface coating industry, specially designed for the end filtration of spray booth. They are made of high-performance hot-melt non-woven fabrics and composed of fracture-resistant synthetic fibers, and adopt an incremental structure, that is, the fiber density in the pure air direction gradually increases, the filtration efficiency also increases, and the service life is longer.
Because the service life of the filter element of the water purifier is only based on the water in a certain place, this standard is definitely not applicable all over the country. If the water quality in the south is taken as the standard, the north is lacking; If we take the water quality in the north as a reference, the water quality in the south will be too high, which itself has the lack of standards. Therefore, the replacement of water purifier filter depends on the local water quality.
