Air Purifier Germicidal Disinfection Function Type

Germicidal disinfection type

Including photocatalytic technology, active oxygen technology

Solid state pollutant removal type

There are mainly mechanical filtration, electrostatic dust collection, electrostatic standing electrode, negative ion and plasma method filtration, etc. Among them: mechanical filtration, electrostatic dust collection, electrostatic standing pole passive purification (filtration), only the air filtered through the filter material; negative ion and plasma method filtration for active purification (filtration), the purifier actively release purification factors for air purification.

(1) Mechanical filtration generally captures particles in the following four ways: direct interception, inertial collision, Brownian diffusion mechanism, screening effect, which is effective in collecting fine particles but has a large wind resistance, in order to obtain high purification efficiency, the cartridge needs to be dense and regularly replaced.
(2) Electrostatic dust collection is the use of high-voltage electrostatic field to ionize the gas so that the dust particles charged adsorption to the electrode dust collection method, when the air flow is too fast or when the particles are large capture effect is poor, adsorption is easy to detach from the formation of secondary pollution.
(3) electrostatic electret filtration to “high-efficiency electrostatic air filter” as the representative, using a breakthrough in carrying permanent electrostatic filter material, can effectively block air particles greater than 0.1 microns of pollutants, such as dust, hair, pollen, bacteria, etc., while ultra-low impedance to ensure stable operation of air conditioning and cooling effect. However, it can only filter or treat the air that flows through it.
(4) Negative ion and plasma method to remove indoor particle pollutants work similarly, both by making airborne particles agglomerate to form larger particles and settle [4], which can act on particles from 0.001 microns to 100 microns, this process is irreversible and dust reduction is more complete. The technology uses the principle of air diffusivity, can be multi-space, large area of the air and object surfaces to implement active purification.

Gaseous pollutant removal type

Remove formaldehyde, benzene and other harmful decoration residues, mainly active oxygen decomposition and activated carbon adsorption two kinds of technology. The principle of activated oxygen decomposition is to react with formaldehyde (HCHO), benzene (C6H6) and other carbonyl (carbon oxygen) and hydrocarbon (hydrocarbon) compounds to generate CO₂, H2O, O₂, etc., so as to completely eliminate the above harmful residues.
