1. How long is the service life of the water filter cartridge?
At present, most water purifier manufacturers will set a service life for the water filter cartridge. For example, the service life of the ultrafiltration membrane filter cartridge is generally 24-36 months; the service life of the reverse osmosis (RO) membrane cartridge is generally In about 18 months, the service life of the adsorbent filter cartridge such as activated carbon filter cartridge is generally about half a year to about one year. The filter cartridge that does not discharge sewage, such as pp cotton, can only be used for about 3 months. Most of these service life is determined by the water filter manufacturer based on the actual water output of the water purifier. This method is also the result of testing in the urban tap water environment; of course, these theories do not represent the service life of the water filter cartridge in the actual daily life. The actual service life of the filter cartridge has a great relationship with the maintenance.
2.When does the water filter cartridge need to be replaced?
A.Ultra-filter and RO membrane : When the water output of the water purifier is greatly reduced, it is much smaller than the original water flow or does not return to the original water output after washing, which can not meet your water demand. At this time, you need to replace the filter cartridge.
B.compound activated carbon filter: When you feel that the taste of purified water is poor and unacceptable, you need to replace the carbon block filter cartridge. In addition, regardless of the frequency of use, if the filter cartridge is installed or replaced for more than one year, it must be replaced.
C.PP cotton filter: the cartridge is usually replaced once every three months. You can judge whether to replace it by observing the color change of PP cotton filter. The use time of PP cotton filter cartridge can not exceed six months.
In fact, the water filter determines the health of the drinking water in the home. If the filter cartridge is not replaced for a long time, it may cause “secondary pollution” to the filtered water. Therefore, the water purifier must maintain and replace the filter cartridge in daily use. We only pay attention to the maintenance of water purifiers,and replace the filter cartridge in time according to the water quality, product condition and water consumption to ensure that the water quality of the purified water meets the qualified drinking standard, and achieve the best performance of the water filter.
Of course, if the water output of the filter is small, it generally does not mean that the quality of the filter cartridge is not good. The main reason may be low water pressure or poor raw water quality, which causes the filter element to clog.
