How to judge the change of the water purifier filter and how often

The effect of the water purifier on filtering water quality is largely due to the filter element inside it. When the filter element filters water for a long time, it is easy to have various kinds of dirt or other impurities, and it must be replaced to ensure that the function can be played again. So, how do you judge the change of the water purifier filter and how often?

First, how to judge the water purifier filter should be changed

1. The water in the water purifier becomes smaller. Under the same conditions (such as the same water pressure and water temperature), the water purifier produces less water. Then it is very likely that the filter element is blocked. If the water purifier filter is close to its service life, it is necessary to replace the new filter element in time.

2. The RO reverse osmosis water purifier makes the water too fast. The water purifier has a phenomenon that the water is obviously accelerated. This situation is generally caused by the damage of the RO membrane. At this time, we have to replace the new RO membrane, otherwise the water purifier will not have the filtering effect.

3, the water purifier outlet is very bad. This is because the water purifier filter filters too much impurities and bacteria, and it takes too long to accumulate at the filter element, causing secondary pollution to tap water. This is also telling us that we need to replace the filter.

4. The water purifier is estimated to have reached 80% of the service life of the filter by time. The service life of the filter element is an ideal period for the use of the water purifier filter. We all know that there is a gap between ideal and reality. In fact, in the community where water pollution is serious, the filter can't be used for such a long time. It is not recommended that you wait until the filter element expires before changing the water quality. If it is too late, it should be replaced.

Second, how often the water purifier filter is changed

Each type of water purifier will be different. The different water purifier filtration process and structure are different, but in general, most of the commonly used water purifier filters are divided into the following, and how long the water purifier filter Replace it once and summarize it as follows:

1. Hollow fiber ultrafiltration membrane (UF) filter: 3 years.

2. Reverse osmosis membrane (RO) filter: 3 years or so.

3, granular fine wash coconut shell activated carbon filter: six months to one year.

4. Block sintered activated carbon (CTO) filter: half a year to one year.

5, PP cotton filter: 3-6 months.

6, KDF filter: 2-3 years.

7, medical stone (tourmaline) filter: six months to one year.

8, ceramic filter: six months to a year.

9, far infrared mineralized ball filter: about a year.

10, after the activated carbon (small T33, large T33) filter: about a year.

11, negative ion energy ball filter: six months to one year.

12, soften the filter: about half a year.

13, magnetized filter: six months to one year.

14, silicon phosphate filter: 2--3 years.

15, quartz sand filter: 1--2 or so.

16. Manganese sand filter (FF): half a year to one year. .

How do I determine if the water purifier filter has been changed and how often? If you find that your home water purifier filter needs to be replaced, you are advised to replace it in time. Under normal circumstances, the filter element of the water purifier should be able to be replaced periodically. If the filter element of the water purifier is not regularly replaced, the water quality that it drinks is prone to many troubles.
