Now many families use the water purifier, but the household water purifier is different from other electrical appliances. Its core part - filter element is a consumable product, which needs to be cleaned and replaced regularly.
Harm of not changing filter element
1. The filtering effect is weakened, affecting human health
When the filter element works for a long time, the filter element full of pollutants will cause blockage, which will not only reduce the amount of pure water flowing out, but also reduce the filtering effect. Over time, some harmful impurities may enter the body.
2. Increased maintenance cost of water purifier
If the filter element is not replaced for a long time, it will be in an overload working state, which will shorten the service life of the filter element. Especially when the service life of the primary PP cotton filter element expires, if it is not replaced, it will increase the filtering burden of the later filter elements, resulting in the blockage of the filter element and the termination of service time in advance. However, the cost of RO membrane filter element is high, which will eventually increase the cost.
3. The service life of water purifier is shortened
When all levels of filter elements are affected and the service life is shortened, the operation of the whole machine will become slow, and the machine may soon "die".
In addition, the replacement frequency of the filter element of the water purifier is related to the local water quality and water production effect. Generally, it must be replaced at least half a year or more than a year. Therefore, in order to maintain the water purifier, it is necessary to maintain the filter element - clean and replace it in time.
So how to determine whether the filter element of the water purifier needs to be replaced?
First move: judge the taste of water
Replace the activated carbon filter element with reference to the taste of the effluent.
The activated carbon filter element is mainly used to absorb the peculiar smell and color in the water. When the taste of the water outlet from the water purifier is too different from that before, or even has peculiar smell, we need to replace the activated carbon filter element, usually within one year.
Second move: see the amount of water
Replace the filter element with reference to the water output of the water purifier.
Once it is found that the water output of the water purifier decreases and the reason for the decrease of the water pressure of municipal tap water is eliminated, it indicates that the filter element of the water purifier may be blocked. At this time, the first thing we should do is to clean the water purifier. After washing, the water output still does not change, so the filter element needs to be replaced.
Third move: look at the service life of the filter element
Refer to the service life of the filter element of the water purifier.
We can also refer to the service life of each filter element indicated in the operation manual of the water purifier. Once it is close to the service life of the filter element, it shall be replaced immediately.
In order to ensure the quality of the outlet water of the water purifier, the filter element must be replaced before the service life of the filter element is reached.
At present, most filter elements in the market have a fixed service life. The general reference data is that the ppcotton filter element is 3 months, the activated carbon filter element is 6 months, the post activated carbon filter element is 12 months, and the ultrafiltration membrane and RO reverse osmosis membrane are 3 years.
In addition, many water purifiers now have the filter element prompt function. If you can't remember the service time of each filter element, you can observe the strip indicator on the machine. Under normal circumstances, the indicator light column is full of blue. With the passage of time, the indicator light column will go out one by one.
When the service time exceeds the time limit, if you feel that the water quality becomes worse or there are other abnormalities, it is likely to be the problem of the filter element, please replace the filter element of the water purifier in time.
If the filter element of the water purifier is maintained regularly, properly used and effectively cleaned and maintained, it can not only keep the family drinking clean water at any time, but also prolong the service life of the filter element. For simple filter element replacement of water purifier, users can operate at home, while for more complex or uncertain cases, users must contact after-sales professionals.
