After a long time of use, the filter element should be replaced. When the length of the filter element we want to replace is insufficient, it can be solved by adding a rubber pad. Also pay attention to the filter element when placing the filter element. Do not harden it when screwing the filter bottle. Unscrew the filter bottle to re-align the filter element to avoid damage to the filter element. After the filter element is installed, it must be rinsed before it can be connected to the back system. The general flushing time should be more than 5 minutes. In fact, there is still a problem. When is the filter element replaced at any time, there is no hard standard. The filter filter usage time will depend on the water quality. Generally, it is 6-8 months, but it is better not to exceed 1 year.

After we choose a good PP filter, it is our operation problem, the correct installation and replacement of the filter, will ensure the normal operation of the filter.
The PP cotton filter has a uniform and dense pore size, and the highest precision of filtration can reach 1μm. It is mainly used to filter out impurities larger than 1μm in tap water. In addition, the filtration process of PP cotton filter is because the PP cotton filter belongs to the first filter of the water purifier. More than 80% of the impurities will be filtered out at this level, and the more impurities are filtered, the easier the filter element will block. Therefore, the life of the PP cotton filter is very short. The area with poor water quality may need to be replaced after more than two months, and the area with better water quality will not exceed six months. Therefore, if you purchase a PP cotton filter inside the household water purifier, in order to avoid secondary pollution of the water purifier and affect the filter effect of the filter, it is recommended that you replace the filter every 3-6 months.
