Air purifier also known as "air cleaner", air freshener, purifier, refers to the ability to adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odour, formaldehyde and other decoration pollution, bacteria, Allergens, etc., effectively improve the air cleanliness of products, mainly divided into household, commercial, industrial, building.
The air purifier is mainly composed of motor, fan, air filter and so on. Its working principle is: the motor and fan in the machine make the indoor air circulate and flow. The polluted air passes through the air filter inside the machine to remove or adsorb all kinds of pollutants, Some types of air purifiers also add a negative ion generator to the air outlet (the high voltage in the negative ion generator produces a DC negative high voltage when working), which ionizes the air and produces a large number of negative ions, which are sent out by a micro fan. Form anion airflow to achieve the purpose of cleaning and purifying the air.
Air purifiers are used in home, medical and industrial fields. The main function is to remove particulates from the air, including allergens, indoor PM2.5 and so on. At the same time, it can also solve the air pollution problem of indoor, underground space and vehicle caused by decoration or other reasons. Because the release of air pollutants in relatively closed space has the characteristics of persistence and uncertainty, using air purifier to purify indoor air is one of the internationally recognized methods to improve indoor air quality.
The air purifier has a variety of technologies and media that enable it to provide clean and safe air to users. The commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, superstructure light mineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc. Synthetic fiber HEAP high efficiency material, anion generator and so on. The existing air purifiers are often used as compound type, that is, a variety of purification techniques and material media are used simultaneously.
