When will the household water purifier filter change in the whole house water purification project?
When is the filter for a household water purifier changed? See these four signals clearly!
The household water purifier needs to be replaced after a long time use, but most of the professionals who are not engaged in household water purifiers do not know when it is better to replace the filter. And many after-sales personnel just tell us the service life of the water purifier filter, because it is not clear how the local water quality is, and it is impossible to give a certain filter replacement time. As a result, the water purifier users questioned the water after using it for several months. : Is it possible to drink this water directly? Isn't it time to replace the filter?
So how do we judge whether it is necessary to replace the water purifier filter? The following four water purifiers "feed back" signals to us. When encountering the following conditions, it means that we should replace the water purifier filter.
First: the water purifier makes water smaller.
Under the same conditions (for example, water pressure and water temperature are the same), the water purifier makes less water. Then it is very likely that the filter element is blocked. If the water purifier filter element is approaching its service life, you need to replace the water filter with a new filter element. The following figure is a comparison of the filter element before and after use. Sediment (impurities such as sand that pass through the micropores of the filter core and are intercepted) lead to less effluent.
Second: RO reverse osmosis water purifier makes water too fast.
The water purifier appears to have a significantly accelerated water output. This situation is generally caused by damage to the RO membrane. At this time, we must replace the new RO membrane, otherwise the water purifier will completely lose its filtering function.
Third: The water outlet of the water purifier is very poor.
Such a situation is because there are too many impurities and bacteria filtered by the water purifier filter element, and the accumulation time at the filter element is too long, causing secondary pollution to the tap water. This is also telling us that we need to replace the filter element.
Fourth: The water purifier of the whole house water purification project is estimated to have reached 80% of the service life of the filter element according to time.
The service life of the filter element is the ideal period of use of the water purifier filter element. We all know that there is a gap between the ideal and the reality. In fact, in the areas with serious water pollution, the filter element can not be used for such a long time. In places with good water quality, it is not recommended to wait until the filter expires before changing. We generally replace the filter element when it reaches about 80% of its ideal life.
