How to clean PP meltblown filter cartridge? The water purifier should be rinsed for the first time in use, with the purpose of flushing out the protective liquid in the water purifier. Here's how: Turn on the tap tap, tap water inlet ball valve, and purification faucet, and rinse for 15 minutes until the water is clear and foam-free.

During the flushing process, it is important to turn the tap on and off frequently (off for 3 seconds, on for 10 seconds) so that the water flow forms a pulsating impact, so that the flushing effect will be better. After that, turn off the sewage faucet, turn on the purification faucet, and use it normally after 5 minutes of water production.

It is recommended to open the tap to rinse after taking the purified water, so as to wash away the intercepted pollutants in time and maintain the high water flux of the water purifier, so as to prolong the service life.

Backwashing to restore water production: If the water production of the water purifier is still relatively small after passing the flush, you can consider backwashing the water purifier. There is generally a backwash button on the water purifier, which can realize the backflushing of water flow to flush out the blockage in the PP meltblown filter element.

(1) When the water purifier is not used for more than three days, the water purifier should be rinsed for 2-5 minutes when used again until the water in the water purifier is exhausted.

(2) In the case of water supply stoppage, please open the sewage faucet to drain the sediment and rust in the water pipe, and then open the purification faucet to use the purified water.

(3) When the water purifier fails, please close the tap water inlet valve immediately, cut off the water inlet of the water purifier, and do not disassemble it by yourself. Products that only replace the PP meltblown filter element cannot guarantee that there is no secondary pollution on the inner wall of the shell and the outlet pipeline.

The replacement cycle of the filter element of different water purification products is also different, PP cotton with lower cost must be replaced once a month, and activated carbon must be replaced once a month. In addition to replacing the filter cartridge, parts such as outlet lines need to be cleaned and disinfected on time, otherwise the contamination caused by the equipment is much greater than the untreated water. Therefore, it is especially important to purchase qualified water purifier products.
