As people’s health awareness increases, more and more attention is paid to household water safety issues. Various water purification equipment has emerged on the market. However, due to the lack of knowledge about household water purification, many people will ask such questions: A water purifier is installed at home, is it necessary to install a pre-filter? Which is better, pre-filter or water purifier?

The difference between pre-filter and water purifier is still very obvious. Their installation positions are different. The installation position of the pre-filter is at the front end of the pipe where the tap water enters the whole house, that is, if the external tap water wants to enter the house, All must go through the filter of the pre-filter. If the water contains sand and rust mixed in the water, the filter of the pre-filter can filter out these impurities in the first time to ensure that the incoming tap water can be used as domestic water. Standards. But the water purifier is different. It is installed at the terminal of the tap water, which is the place where people are most directly contacted.

The pre-filter is the first level of household water filtration. The water filtered by the pre-filter cannot be directly drunk, but it makes domestic water safer and healthier. The water purifier is to filter the water filtered by the pre-filter and filter it again. The water purified by the water purifier can be used as direct drinking water. It can be seen that the pre-filter has played a significant role in improving the water quality of the entire house. It is precisely because of the first filtration process that the water purifier can more finely purify the water source.

In addition, the quality of the water purified by the water purifier can be used not only as domestic water, but also as direct drinking water. It belongs to fine filtration, but this must be based on the first filtration, otherwise the purification effect will not only be greatly reduced, but also Will damage the water purifier equipment. It is precisely because of the first rough filtration that the faucet and the concealed pipeline will not be blocked by sand and rust, so the pre-filter is also called "the first pass of water safety."

From the above points, the water purifier is definitely better than the pre-filter, but the water purifier and the pre-filter are in a coordinated relationship. For families that have already installed a water purifier, it is recommended to also install a pre-filter.
