Analysis of air purifier working principle by air purifier manufacturer

There are five principles of air purifier, physical, electrostatic, chemical, anion and composite. In general, physical purification is the most commonly used and most effective method. For example, dust, pollen, allergens, viruses and other large particles can be filtered by the HEPA technology in the way of physical purification. The harmful substances such as benzene, toluene, formaldehyde and other odors can be purified by adsorption of activated carbon in physical purification. The passive purification method can only purify the air inhaled. Active purify means can have purify effect to whole space. Active and passive composite purification is a combination of the two, and the effect is better.

There are many different technologies and media in the air purifier, which enables it to provide clean and safe air to users. Common air purification technologies include: low temperature asymmetric plasma air purification technology, adsorption technology, negative ion technology, negative oxygen ion technology, molecular complexation technology, photocatalyst technology, HEPA efficient filtration technology, electrostatic dust collection technology, active oxygen technology, etc. The material technology mainly includes: photocatalyst, activated carbon, synthetic fiber, HEAP efficient material, negative ion generator, etc. At present, the existing air purifier in the domestic market is more composite, that is, a variety of purification technologies and materials medium are adopted at the same time.

Entering the 1980s, the emphasis on the principles of air purifier has turned to air purification methods, such as household air purifier. Past filter in removing the stench in the air, toxic chemicals and poisonous gas is very good, but cannot remove mould spore, the virus or bacteria, and the new family and office use air purification machine, not only can clean the toxic gases in the air, also can purify air, remove the bacteria, viruses in the air, dust, pollen, mold spores, etc.

Now, the principle of the air purifier has been designed and made in many different ways, and each technological change has brought remarkable effect for people's indoor air quality improvement. And all these purposes only one: hope can purify indoor air to improve people's quality of life.

At present, most of the products of air purifier manufacturers mainly consist of: chassis, filter section, air duct design, motor, power supply, liquid crystal display, etc. The life is decided by the motor, the purification efficiency is determined by the filter section, and the quiet is decided by the air duct design, housing, filter section, motor.
