No matter what kind of water purifier, the filter element needs to be replaced. ? The filter element of the water purifier isolates the impurities in the water, and clean water flows out. However, the impurities blocked by these filter elements cannot be completely washed away after backwashing. Over time, the impurities accumulate more and more, and the water purifier will be blocked.

If the filter element is used for a long time without replacement, there are usually two consequences. One is that the filter element is blocked, and the water flow will become particularly small. The other is that the pore size of filtration becomes larger, and pollutants in water can still flow out, which can not achieve good filtration effect.

Precautions:

1. The water purifier is different from other household appliances. You can't buy it once and for all. Need to be cleaned or replaced regularly.

2. During the service cycle of the filter element of the water purifier, the standard of regular replacement should be strictly implemented, and the post-maintenance service of the filter element should be standardized.

3. Usually, the replacement cycle of PP cotton filter is 3-6 months, and the recommended replacement period of activated carbon filter is 10- 12 months; The ultrafiltration membrane is recommended to be replaced every 20-24 months, and the RO membrane filter element is recommended to be replaced every 24 months or so. Of course, the specific replacement time depends on the local water quality.

4. Instead of drilling holes in the counter, the original faucet is replaced by a specially designed 2-pipe faucet, which is connected to the clean water outlet of the water purifier and the 4-pipe faucet is connected to the sewage outlet of the water purifier.
