What are the filtration methods of common water purifiers?

Generally speaking, there are two kinds of filtration methods for water purifiers: adsorption and filtration. Among them, the filter water purifier can be divided into two types according to the size of the filter hole and the purification degree of water quality, one is conventional filtration and the other is precision filtration. Water purifiers on the market are mainly divided into the following categories.

First of all, according to the different classification of water quality

This water purifier is mainly used for urban tap water, turbid tap water, high hardness water quality and suitable limestone water quality.

Second, according to the purification level classification

Generally, it can be divided into coarse filtration, activated carbon adsorption, ion exchange resin, hollow fiber and reverse osmosis membrane. Common water purifiers include ultrafiltration water purifier and RO water purifier.

Three, according to the classification of purification grade

Mainly classified by filtration grade, it can be divided into 1-5 grades of filtration. This kind of water purifier is mostly RO reverse osmosis pure water machine, which can also be called compound water purifier.

Summary: At present, most water purifiers on the market fall into the above categories, and the filtration effect is different according to the price and region. The structure of basic household water purifier consists of coarse filtration, activated carbon adsorption, ion exchange resin, central fiber and RO reverse osmosis membrane.
