With the improvement of living standards and the seriousness of water pollution, many families will install water purifiers at home in order to drink healthy and safe water. For a water purifier, the “filter element” is the heart, and it is all up to it to intercept impurities, harmful bacteria, and heavy metals in the water.
However, many families often let the filter element “extremely long service”, or are vague about the replacement time of the filter element. If this is the case with you, then today’s “dry goods” must be read carefully. It will teach you how to self-check whether the filter element is expired!
Self-test method 1: water flow changes
If the water flow of the water purifier is significantly less than before, it can no longer meet the normal needs. After eliminating the water temperature and water pressure factors, flushing and restarting the filter element, the water flow has not returned to normal. Then it may be that the filter element of the water purifier is blocked, and the “distress signal” sent out requires inspection and replacement of the PP cotton or RO membrane filter element.
Self-test method 2: taste changes
When you turn on the faucet, you can smell the smell of “disinfected water”. Even after boiling, there is still a smell of chlorine. The taste of the water decreases, which is close to that of tap water. This means that the activated carbon filter element has been saturated and needs to be replaced in time to ensure The filtration effect of the water purifier.
Self-test method three: TDS value
TDS pen is currently the most commonly used detection tool for domestic water. TDS mainly refers to the concentration of total dissolved substances in water. Generally speaking, the cleaner the water quality, the lower the TDS value. According to the data, the TDS value of 0~9 belongs to pure water, the TDS value of 10~50 belongs to purified water, and the TDS value of 100~300 belongs to tap water. As long as the filter element of the water purifier is not blocked, the quality of the water filtered by the water purifier will not be too bad.
Of course, it cannot be said that the lower the TDS value, the healthier the water. Qualified drinking water must meet the standards of comprehensive indicators such as turbidity, total bacterial colony, microbial count, heavy metal concentration, and organic matter content. Relying on the TDS water quality test alone cannot directly judge whether the water quality is good or bad, it is just a reference.
Self-inspection method 4: Reminder for core replacement
If your water purifier is equipped with a smart core replacement reminder function, it will be even easier. You can judge whether the filter needs to be replaced according to the color change of the filter prompt light on the machine or the life value of the filter. If the indicator light is red and flashing or the life value shows 0, it proves that the life of the filter element has expired and needs to be replaced as soon as possible to avoid affecting the filtering effect.
Filter Replacement Time Suggestion Table
Here is the service life of each filter element. In order to ensure the water quality of the water purifier, it is recommended to replace the filter element before the end of its life. At the same time, the replacement time of the filter element will also be affected by the raw water quality, water quality in different regions, water consumption, etc., so the replacement time of the filter element in each region will also be different.
If the filter element is not replaced on time, it will not only weaken the filtering effect, but also allow impurities to adhere to the filter element for a long time, which will easily cause secondary pollution of water quality. Therefore, in our daily use, we must pay attention to regular replacement of the filter element, and purchase genuine filter elements through official channels, so that we can drink safe and healthy water.
