How to select an air purifier?

When choosing an air purifier, the problems consumers want to solve are generally classified as:

1. Particulate dust, namely PM2.5, meets the standard;

2. Remove formaldehyde, benzene and other organic pollutants;

3. Kill bacteria and viruses, rhinitis, asthma, respiratory symptoms significantly reduced;

4. Both air purification and humidification functions;

At present, all air purifiers on the market with high-efficiency HEPA filters can solve the problem of PM2.5, and the removal rate is above 90%, so there is no problem for indoor PM2.5 to reach the standard;

In the product series of each brand, there will be a model specially used to remove formaldehyde and benzene, which is characterized by the amount of activated carbon. There are also products that use activated carbon+high-efficiency HEPA filter screen. Because of the special formaldehyde removal, the amount of activated carbon of this type of model is relatively ordinary, and the conventional amount is large;

There is also an air purifier that uses high efficiency HEPA+plasma technology, or high efficiency HEPA+electrostatic precipitation technology, or high efficiency HEPA+EMF sterilization technology. It mainly filters PM2.5 and sterilizes at the same time. This type of product is more suitable for people with allergic diseases, such as rhinitis, asthma, recurrent respiratory tract infection, and cross infection of influenza;

The air purifier integrating air purification and humidification is mainly used to humidify the air while meeting the PM2.5 standard. It is generally not compatible with sterilization technology, because water and electricity cannot be stored together.

To sum up, the choice of air purifier should be based on the purpose of its own, and the brand air purifier should be selected according to the technology and price of the product. No *, only better and more suitable air purifier.
