I want to buy a kitchen water purifier, what brand is good?

It is recommended that you first understand the two major technologies in the current water purifier industry: 1. Reverse osmosis. 2. Ultrafiltration. Reverse osmosis is currently recognized as the safest and most scientific water treatment technology in the world.

It is pure water, that is, there are only water molecules, so it is the safest, so the reverse osmosis machine is also called pure water machine. The filtration accuracy of ultrafiltration is second to that of reverse osmosis, and the output is not pure water, because the pore size of the ultrafiltration membrane is larger than that of reverse osmosis.

Since it is not pure water, there may be bacteria, viruses and chemical pollutants with a diameter smaller than the pore size of the ultrafiltration membrane.

Of course, there may be some elements that are beneficial to the human body, but in the current water environment, safety is difficult to guarantee, how can we talk about health? So I think it's better to use a reverse osmosis water purifier. In addition to the above two technologies.

The water purifiers are all microfilters, and they must not be drunk directly.

At present, the standard configuration of water purifiers in the water purification industry:

The first stage: PP cotton, function: to filter large particles of pollutants.

The second stage: granular activated carbon GAC, function: adsorption of chemical pollutants in water.

The third stage: sintered activated carbon CTO, function: further adsorption of chemical pollutants in water.

Fourth stage: RO reverse osmosis membrane Ultrafiltration membrane, function: intercept untreated pollutants in the first three stages.

Level 5: Post-activated carbon T33, function: improve the taste of pure water and purified water.
