The working principle of the water purifier is mainly through a variety of filtration technologies, removing impurities, odors, bacteria, viruses, heavy metals and other harmful substances in the water, so as to provide purer and healthier drinking water. Common types of water purifiers include:

Ultra-filtration water purifier: using ultra-filtration membrane as the core filtration element, it is able to remove suspended solids, colloids, bacteria, viruses, etc. in water, but the removal effect of heavy metals and some small molecules of organic matter is limited.

Reverse osmosis water purifier: using the high-precision filtration characteristics of reverse osmosis membrane, can effectively remove almost all the impurities in the water, including heavy metals, organics, bacteria, viruses, etc., the output of water close to pure water.

Activated carbon water purifier: rely on the adsorption effect of activated carbon to remove odor, residual chlorine, organic matter in the water.

Nanofiltration water purifier: Its filtration precision is between ultrafiltration and reverse osmosis, which can remove most of the harmful substances, while retaining a certain amount of beneficial minerals.
