Water purifier is also called water purifier.
According to the filter structure, it is divided into RO reverse osmosis water purifier, ultrafiltration membrane water purifier, energy water purifier and ceramic water purifier.
RO reverse osmosis water purifier comes standard with 5 stages of filtration, namely:
The first stage is PP cotton, which is a primary filtration, mainly filtering large particles visible to the naked eye, such as sediment and rust.
The second stage is granular carbon, which has a strong interception effect on organic matter and inorganic colloid in water, and has the functions of deodorization, odor removal, residual chlorine removal and decoloration.
The third stage is compressed carbon, which has a good removal effect on odor, residual chlorine, aromatic hydrocarbon and COD.
The fourth stage is RO reverse osmosis membrane, the pore size of which is 0.000 1 micron (0. 1 nanometer). A bacterium has to be reduced by 4000 times, and an infectious virus has to be reduced by more than 200 times before it can pass, so it is ok.
Effectively remove harmful substances such as bacteria, viruses, heavy metal ions and pesticide residues in water.
The fifth stage is the post-activated carbon (also called small T33) stage 5; Using the adsorption principle of activated carbon, residual chlorine and toxic and harmful substances in water can be effectively removed, and the water quality and taste can be improved.
Ultrafiltration water purifier is mainly ultrafiltration membrane, supplemented by other filter elements such as activated carbon (excluding energy filter element). Ultrafiltration water purifiers are divided into vertical and horizontal types according to installation methods.
The vertical ultrafiltration water purifier consists of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane and T33.
Horizontal ultrafiltration water purifier "commonly known as pipeline ultrafiltration machine" consists of stainless steel shell, internal pressure ultrafiltration membrane and KDF.
Ultrafiltration water purifier adopts 1 to 12 filter element for filtration, which generally consists of PP cotton filter element, carbon filter element, ultrafiltration membrane and some functional filter elements such as alkaline weak alkali dechlorination.
To sum up, RO machine is more expensive, and ultrafiltration is more suitable than P .. In the market, RO water purifier is used in most areas in the north, and ultrafiltration machine is used in the south. However, with the aggravation of water pollution, the water purifier market has a weak momentum beyond the ultrafiltration machine market.

The more popular brands in the market are Midea, Hamilton, Qinyuan and Angel. Pay attention to the following points when purchasing a water purifier:
First of all, look at the local water quality, whether to use RO machine or ultrafiltration machine.
Second, look at the service level and attitude of dealers.
Third, look at the price level you accept.
Fourth, look at after-sales service
Fifth, look at the appearance of the product, like it or not.
Sixth, look at the product function, whether it is suitable for use,
Seventh, look at the daily drinking water, 75G or 50G.
-Listen and see more, understand first, and then choose!

Meng should examine the following points:
1. Product quality guarantee, 3C certificate, approval documents, etc.
Second, support policies are in place after China's accession.
Third, whether there are mature sales methods,
Fourth, consider Hamilton, who went to the market to teach water purifiers knowledge and sales methods.
Don't just look at online publicity, but also look at real sales! If it can't be sold, no matter how good the brand is, it won't make that money. It's better to be realistic in business.
Join the water purifier to inspect the product quality, support policies, sales methods, consider Hamilton, and some people go to the market to teach the water purifier knowledge and sales methods.
