The Necessity and Cycle of Cartridge Replacement
(A) Why replace the cartridge regularly
With the increase of the use of time, the cartridge will gradually be filled with the retained impurities. PP cotton cartridge will be adsorbed by a large number of silt and clogging, resulting in slow water flow.
Activated carbon cartridge in the adsorption of saturation, not only can not continue to remove the odor and residual chlorine in the water, but also may be adsorbed before the re-release of hazardous substances into the water. Ultrafiltration and reverse osmosis membrane cartridge surface will be covered with pollutants to reduce the efficiency and accuracy of filtration.
Precision. If the cartridge is not replaced in time, the water purifier will greatly reduce the effect of water purification, and may even produce secondary pollution, posing a threat to human health.

(B) Factors affecting the replacement cycle of the filter cartridge
Filter replacement cycle is not fixed, it is affected by a variety of factors. First of all, the water quality, if the water in the high content of impurities, pollution is serious.
The service life of the cartridge will be shortened accordingly. For example, in some areas with high water hardness, the calcium and magnesium ions in the water are easy to scale on the surface of the cartridge, accelerating the loss of the cartridge.
Secondly, water consumption, family population, water consumption will make the cartridge more quickly reach saturation. In addition, different brands and models of water purifiers, its cartridge design and filtration capacity is also different, which will also affect the replacement cycle.
Generally speaking, PP cotton filter may need to be replaced once every 3-6 months, activated carbon filter 6-12 months, ultrafiltration membrane filter 1-2 years, reverse osmosis membrane filter 2-3 years, but this is only a general reference, the actual situation should be based on the specific use of the situation.
