How do I know if the filter element of my water purifier should be replaced?

The following situation indicates that it should be changed:
1. The water system of water purifier becomes smaller. Under the same conditions (such as the same water pressure and water temperature), the water produced by the water purifier becomes less. It is likely that the filter element is blocked. If the filter element of the water purifier is close to its service life, it is necessary to replace the filter element of the water purifier with a new one.
2. RO reverse osmosis water purifier makes water too fast. The water outlet of the water purifier is obviously accelerated, which is generally caused by the damage of RO membrane. At this time, we must replace the new RO membrane, otherwise the water purifier will lose its filtering function completely.
3. The water from the water purifier has poor taste. The reason for this is that there are too many impurities and bacteria in the filter element of the water purifier, and the time accumulated at the filter element is too long, resulting in the secondary pollution of the tap water. It also tells us that we need to change the filter element.
4. The water purifier has reached 80% of the service life of the filter element according to the time calculation. The service life of the filter element is the ideal life of the filter element of the water purifier. As we all know, there is a gap between the ideal and the reality. In fact, the water pollution is serious, the filter element can not be used for such a long time. For places with good water quality, it is not recommended to wait until the filter element expires. We usually replace the filter element when its service life reaches about 80% of its ideal life.
