I just changed to a big house, and the kitchen needs to be equipped with a water purifier, what are

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, and the water that comes out through the reverse osmosis membrane is basically pure water, that is, 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 it is not pure water, because the pore size of the ultrafiltration membrane is larger than that of reverse osmosis, so some manufacturers advertise that the ultrafiltration water purifier is a water purifier that can retain minerals, in fact, it is to avoid the heavy and light, since it is not pure water, then 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 to talk about health? So I think it's better to use a reverse osmosis water purifier.

Water purifiers other than the above two technologies 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.

Second Stage: Granular Activated Carbon GAC, Function: Adsorption of Chemical Pollutants in Water Third Stage:

Sintered activated carbon CTO, function: further adsorption of chemical pollutants in water Fourth stage: RO reverse osmosis membrane Ultrafiltration membrane, function:

Interception of the first three levels of untreated pollutants The fifth stage: post-activated carbon T33, function: improve the taste of pure water and clean water.

Internationally renowned big brands are a good choice, depending on your personal preferences, my electrical products are mostly Philips, the quality of big brands is guaranteed, the quality is first-class, the purification effect is guaranteed, my family has just entered a Philips WP4170, the filtration effect rod, can filter out nano-level impurities and bacteria and other harmful substances in the water, the water is pure water, you can drink it directly, super convenient and safe.

Water purifiers can be divided into two categories: gradual tightening water purifiers and self-cleaning water purifiers according to the pipeline design level. The traditional water purifier is a gradual water purifier, and its internal pipeline design filter element is loose in front and tight in the back, which is composed of PP meltblown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon, which is generally composed of these five stages connected end to end. Retention is deposited inside the filter element and needs to be manually dismantled and cleaned at regular intervals to ensure proper machine operation.

The self-cleaning type adopts the new principle of quality circulation, and the impurities are cleaned out at any time, and the inner core is clean to avoid secondary pollution, see the working principle below for details.
