Purchase guide of water purifier

The structure of the home water purifier can be roughly divided into several types: coarse filtration, activated carbon adsorption, ion exchange resin, hollow fiber and reverse osmosis membrane. To choose an ideal and practical water purifier, the following aspects should be considered:

1、 Whether there is a product hygiene license.

Users must understand the importance of product quality when purchasing water purifiers. The measures for the supervision and administration of drinking water sanitation stipulate that the hygiene license issued by the higher level hygiene supervision department shall be obtained and verified by the technical supervision department to meet the national standard for drinking water quality.

2、 Choosing the right filter element is essential.

The first generation of water purifier mainly uses simple filtration such as activated carbon and ceramics, which is easy to breed bacteria and pollute the water source, so it can not achieve the effect of clean water source; the second generation of water purifier uses various artificial polymer membrane filtration, which has significant effect on removing harmful substances in water, but its fatal defect is that it filters out trace elements beneficial to the body. The third generation of water purifier uses nano microcrystalline filter technology, which solves the defects of the second generation of water purifier and filters out harmful substances and heavy metals in the water. So when you choose the water purifier, you must ask the filter technology and the filter material to see whether they can meet their own needs.

3、 Whether there is safe and effective sterilization technology.

The water purification equipment adopts two ways of sterilization, one is to add disinfectant, which can kill some bacteria, but the disinfectant contains a small amount of chemical ingredients harmful to human health; the other is UV sterilization, which is one of the most effective sterilization technologies internationally recognized, because UV sterilization is safe and efficient, which can quickly kill almost all bacteria; and UV sterilization Bacteria are sterilized by physical principles, without any chemicals, and will not have side effects on human body.

4、 Whether there is a perfect after-sales service system.

After many consumers buy some brands, they can't find the maintenance service phone or the address of the maintenance service company. This situation makes consumers helpless and causes waste of resources. Many water purifiers have become furnishings. After sales of water purifiers are mainly focused on the replacement of filter elements. If the filter elements are not replaced for a long time, they will pollute the water source and the water purifier will become a "sewage device". To select water purifier, we must choose perfect after-sales service, such as using customer service system to track customer information, prompting customers and the company to change filter elements, etc.
