Before understanding how to choose a water purifier, we first need to understand the basic working principles and classification of water purifiers. The main function of a water purifier is to remove impurities, heavy metals, bacteria, viruses and other harmful substances from water to provide safe and healthy drinking water. According to different filtration principles and technologies, water purifiers are mainly classified into the following categories:

1. Microfiltration (MF) water purifiers

Microfiltration water purifiers mainly filter large particles of impurities in the water, such as sediment, rust, suspended solids and so on, by means of microporous membranes. Its filtration precision is generally between 0.1 micron and 10 microns, which can effectively remove visible impurities in the water, but the removal of dissolved substances and microorganisms is limited.

2. Ultra-filtration (UF) water purifier

Ultra-filtration water purifier adopts ultra-filtration membrane technology, the filtration precision is between 0.01 micron and 0.1 micron, which is capable of removing macromolecules of organic matter, bacteria, viruses, etc. in the water, but has limited effect on removing small molecules such as heavy metal ions. Ultra-filtration water purifier is suitable for water quality in better areas, can provide more pure drinking water.

3. Reverse osmosis (RO) water purifier

Reverse osmosis water purifier is one of the most advanced water purifiers on the market, using reverse osmosis membrane technology, filtration accuracy of up to 0.0001 microns, able to remove almost all harmful substances in the water, including heavy metal ions, bacteria, viruses, dissolved salts and so on. Reverse osmosis water purifier water quality is high, suitable for a variety of poor water quality areas, but its disadvantage is the high rate of wastewater.

4. Nanofiltration (NF) water purifier

Nanofiltration water purifier between ultrafiltration and reverse osmosis, filtration precision between 0.001 micron and 0.01 micron, can remove most of the organic matter in the water, bacteria, viruses, and some of the heavy metal ions, but the removal of small molecules of salts is limited. Nanofiltration water purifiers are suitable for drinking water needs that require the retention of some minerals.

Key factors for choosing a water purifier

1. Water quality condition

The water quality condition in different areas varies greatly, some places have hard water containing more calcium and magnesium ions; some places have poor water quality containing more heavy metals, bacteria, viruses and other harmful substances. Therefore, when choosing a water purifier, you should first understand the local water quality conditions. For areas with hard water, you can choose a water purifier with the function of water softening; for areas with poor water quality, it is recommended to choose reverse osmosis water purifier to ensure the safety of drinking water.

2. Outgoing water use
