Air purifier, also known as "air cleaner" air refresher, purification, is the ability to adsorption, decomposition or transformation of various air pollutants (generally including decoration pollution PM2.5, dust, pollen, odors, such as formaldehyde , bacteria, allergens, etc.), improve air cleanliness of household appliances, mainly divided into domestic, commercial, industrial, buildings. Air purifiers in a number of different techniques and media, to enable it to provide a clean and safe air to the user. Air purification technology commonly used are: adsorption technology, negative (positive) ion technology, catalyst technology, photocatalyst technology, ultra-light mineralized structure technology, HEPA efficient filtration technology, electrostatic dust collection technology; materials technology are: photocatalyst, activated carbon, pole filter carbon core technology, synthetic fibers, HEAP efficient materials, negative ion generator. Existing air purifier much more expensive than the complex, which simultaneously uses a variety of techniques and materials purification media. 2 air purifier called "air cleaner" air purifier, purifier, is the ability to adsorption, decomposition or transformation of various air pollutants (generally including PM2.5, dust, pollen, odors, such as formaldehyde decoration pollution, bacteria, allergens, etc.), improve air cleanliness products, mainly divided into domestic, commercial, industrial, buildings.
