How many kinds of air purifiers are there?

Air purifier according to the purification method can be divided into three kinds

1 passive filtration traditional physical filtration, primary net deodorization net activated carbon net HEPA filter,

Mainly the fan will be the air pumped into the machine through the filter particles, bacteria, adsorption of toxic gases and then re-emerge. To achieve the effect of purifying the air, there are many types of filters, such as activated carbon filters, electrostatic filters, HEPA filters, HEPA filters filtering effect is better, of course, the cost is also higher, but also to avoid secondary pollution.

2 Active purification? The use of photocatalysts, negative ions, etc., mostly chemical filtration

It is to release the purification and sterilization factors into the air, active purification of indoor air. Purification and sterilization factor technology has negative ion technology, silver ion technology, low temperature plasma technology, photocatalyst technology, net ion technology group ion technology.

3 composite, that is, passive plus active passive and active combination, the effect is more.

It is a combination of passive and active, usually after the first passive filter processing, in the active purification and sterilization, the effect is better, but generally higher costs.

According to the applicable scene can also be divided into domestic commercial car desktop

According to the different filters can also be divided into bacteria, in addition to PM2.5, in addition to formaldehyde deodorization

According to the purification of the area can be divided into different, such as: 20-50 square meters, 50-80 square meters, etc.

By brand can also be divided into and a variety of such as the United States, the United States, the United States of America? Xiaomi? Brewell, Northenberg, etc.
