What is the role of air purifier

The function of air purifier is to remove particulate matter in the air, including allergens, indoor PM2.5, etc. At the same time, it can also solve the indoor, underground space and car volatile organic matter air pollution caused by decoration or other reasons. Since the release of air pollutants in a relatively enclosed space is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

Air purifier is also known as "air cleaner", air freshener, purifier, refers to the adsorption, decomposition or transformation of various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improve air cleanliness products, mainly divided into household, commercial, industrial, building.

There are a variety of different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc. Material technology mainly includes: photocatalyst, activated carbon, synthetic fiber, HEPA efficient material, negative ion generator, etc. Existing air purifiers are mostly compound, that is, a variety of purification technologies and material media are used at the same time.

Air purifier is also known as the adsorption, decomposition or transformation of various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improve air cleanliness products, mainly used in household, commercial, industrial, buildings.

The part that can make the air purifier play the maximum role is the filter screen. The filter screen is also divided into many kinds, and each screen has a different role.

Type of filter screen

The screen is the most core part of the air purifier, which determines its purification ability. At present, air purifiers on the market mainly use the following kinds of filters, each filter material is not the same, the core is activated carbon filter.

Pre filter: The initial effect filter screen is generally installed in the front of the filter element, mainly filter large particles of dust in the air, pet hair and so on. Is the first line of defense. The initial filter element has a long life, because it can be cleaned directly, almost no cost to worry about.

Activated carbon filter: activated carbon is an internationally recognized efficient adsorption material, mainly filter formaldehyde in the air, gaseous pollutants (second-hand smoke flavor, etc.), the material suggested that you choose columnar activated carbon and coconut shell activated carbon. The higher the weight of activated carbon, the better, the more layers, the higher the efficiency.

HEPA filter: It is mainly used to filter pollen, dust mites, bacteria and viruses in the air. The industry generally divides HEPA filter material into three grades, E, H and U. The HEPA screen of air purifier on the market is commonly used in several grades H11, H12 and H13. Common configurations are H12 and H13 filters, both of which can meet the need for particulate matter purification.
