If there is a water purifier at home and it has been used for a long time, will there be no water because the filter element is blocked? As we all know, tap water is clear and transparent from the naked eye. Why is the filter element blocked after the tap water in the waterworks is filtered normally? In fact, the filter plug is related to the local tap water quality. How often does the filter element of the water purifier change?
With the improvement of people's awareness of healthy drinking water, water purifiers have gradually become essential daily necessities for many families. However, many people are not very clear about the maintenance of the water purifier, and many people rarely take the initiative to read the operation manual after purchasing the water purifier. The instruction manual of the water purifier will indicate the specific replacement time standard of the filter element.
The service life of the filter element of the water purifier is related to the model of the water purifier and the water quality in the place of use. If the service life of the filter element is exceeded, the filtering effect of the filter element will be greatly reduced or even invalid, which will reduce the working efficiency of the water purifier and seriously affect human health.
The reason why the filter element of the water purifier needs to be replaced in time is because the impurities trapped in the water cover the surface of the filter element. In the long run, if the filter element is not replaced in time, once the filter element is blocked, the filtering effect will be greatly reduced, which is likely to cause secondary pollution and seriously affect the health of drinking water.
However, many people will also have some misunderstandings about filter replacement. Let's talk about the common mistakes in replacing filter elements in life!
1 and TDS test pens are qualified and need not be replaced.
TDS is only one of the water quality indicators of 106. Many users think that the tap water tested by TDS pen is qualified, which means that the tap water quality has reached the qualified standard. But in fact, qualified drinking water must meet the requirements of turbidity, total bacteria, microbial number, heavy metal concentration and other comprehensive indicators in order to meet the standards. It is not strict to judge whether the water quality reaches the standard with TDS test pen.
2. The filter element does not look dirty and does not need to be replaced.
Some users will have the consciousness of replacing the filter element, but when they remove the filter element, they find that the color of the filter element doesn't look very dirty and mistakenly think that it is unnecessary to replace it. In fact, this practice is not appropriate. The proportion of substances contained in tap water in different regions is different. In areas where there are many sand and rust particles in tap water, the filter element will look dirty after a long time of use. However, for tap water containing a lot of small impurities such as heavy metal ions and microorganisms, the filter element does not look very dirty after long-term use, but it still needs to be replaced at this time.
3. The filter element is not blocked and does not need to be replaced.
Many users hold water purifiers? Use it to the end? Attitude. As long as the water purifier is normal, there is no need to replace the filter element. In fact, the service life of the filter element needs to consider filtration and adsorption comprehensively. If there are few large particles in the water, the filter element will not be blocked for several years, but a large number of harmful substances such as heavy metal ions and microorganisms will accumulate on the surface of the filter element.
Sometimes seemingly clean tap water actually contains a certain amount of colorless and tasteless, invisible and intangible harmful substances. To this end, friends who have water purifiers at home must remember to replace qualified filter elements in time ~
