First, purification technology.

Various purifiers emerge in an endless stream on the market, and each brand has its own set of purification technology. Undoubtedly, it is best to publicize its own technology, so consumers should keep their eyes open when choosing purifiers and choose the one that suits them best according to their actual needs.

At present, there is no clear classification of air purifiers in China, which is generally classified according to the place of use or the purification technology adopted. According to the place of use, it can be generally divided into household air purifiers, commercial air purifiers, car air purifier and medical air purifiers. For different air pollutants, the purifier will adopt different purification technologies. For example, for dust, porous filter materials such as non-woven fabric/dense fiber mesh are generally used; For lampblack, second-hand smoke and ultra-fine dust, ultra-efficient filters are generally used to filter the effect; Activated carbon technology is mainly aimed at fine particles and macromolecular gases in the air; For bacteria, viruses and small molecules of toxic and harmful gases (formaldehyde, benzene, TVOC, etc. ) In terms of air, photocatalyst air purification technology is mainly used.

Second, the air purification effect

The purification effect generally includes the following aspects: the removal of harmful microorganisms such as bacteria, viruses and molds; Neutralization and decomposition of harmful chemical gases such as formaldehyde, benzene and ammonia; Remove peculiar smell, smoke smell, etc. ; Removal of inhalable particles, etc. However, in order to ensure that all the above aspects have good effects, several purification technologies need to be used together.

Third, the efficiency of air purification.

Purification efficiency generally includes purification speed, comprehensiveness and thoroughness of purification. In other words, can you cover every corner of the room, leaving no sanitary dead ends to prevent bacteria from breeding and spreading again?

Iv. usable area

Because different purifiers have different air volume and purification efficiency, they are suitable for different areas. Regular products will be marked with the recommended use area, and consumers need to pay special attention when buying.

Fifth, humanized design.

The first thing to note is that the air purifier should not make too much noise during operation. In addition, whether the purifier has certain display function and mode switching function.

Sixth, the maintenance is convenient.

Also know whether it is convenient to clean the air purifier before buying. Generally, only the coarse filter screen of the air purifier needs to be cleaned by itself, and other parts generally need to be replaced or repaired at the repairer. This matter needs to be confirmed before buying.

Seventh, ease of use

Pay special attention to whether the air purifier is easy to use when purchasing. The installation of some air purifiers is very complicated, and even the existing building space and equipment need to be dismantled and transformed. In addition, consider the size of the product. If the room is relatively small, it is recommended not to choose an air purifier that is too bulky, which will affect the overall layout of the room.

Eighth, safety and environmental protection.

More and more people are beginning to pay attention to environmental problems, not only outdoor environment, but also indoor environment is more closely related to people. People need to spend most of their time indoors. According to the survey of China Standardization Association, 68% of diseases are caused by indoor pollution! Therefore, when choosing products, it depends on whether there will be secondary pollution and whether it can be saved by people and machines.

Ninth, the continuity of use

When buying this product, we should pay special attention to its service life Although permanent use is not required, at least the most basic service life should be guaranteed. Some products will be ineffective after a few months of use. I don't think this is what people want.

Tenth, the later use cost.

Since you have chosen, you should also consider the later use cost of the product, such as the most basic power consumption and technical maintenance cost.
