There are many kinds and principles of air disinfection machine, such as ozone technology, ultraviolet lamp, filter and photocatalysis. Primary filtration, medium and high efficiency filtration, electrostatic adsorption filtration: effectively remove particles and dust in the air. Activated carbon net: deodorizing function. Photocatalyst network

Antibacterial net assisted disinfection.

Generally, nano-scale photocatalyst materials (mainly titanium dioxide) are used to generate positively charged "holes" and negatively charged oxygen ions on the surface of titanium dioxide. The "holes" combine with water vapor in the air to generate strongly alkaline "hydroxyl radicals", which decompose formaldehyde and benzene in the air into harmless water and carbon dioxide.

Negative oxygen ions combine with oxygen in the air to form "active oxygen", which can decompose the cell membrane of bacteria and protein of oxidation virus, thus achieving the purpose of sterilization, detoxification and decomposition of harmful gases.
