The working principle of medical air sterilizer

Use of air sterilizer types are more, there are many kinds of principle, there is the use of ozone technology, there is the use of ultraviolet lamps, there is the use of filters, there is the use of photocatalytic and so on. Primary filtration, medium and high efficiency filtration, electrostatic adsorption filtration: effectively remove particles and dust in the air. Activated carbon mesh: function of deodorization. Photocatalytic mesh

Antibacterial mesh aids in disinfection.

Photocatalytic materials (mainly titanium dioxide) are generally nano-sized, with the irradiation of ultraviolet light, the surface of the titanium dioxide produces positively charged "holes" and negatively charged negative oxygen ions, "holes" and the combination of water vapor in the air, resulting in a strong alkaline "holes" and the combination of water vapor in the air, and the production of a strong alkaline "holes" and the production of a strong alkaline "holes". The "cavities" combine with the water vapor in the air to produce a strong alkaline "hydroxide radical", which decomposes formaldehyde and benzene in the air, turning them into harmless water and carbon dioxide.

Negative oxygen ions combine with oxygen in the air to form "active oxygen", which can decompose bacterial cell membranes and oxidize viral proteins, achieving the purpose of sterilization, poison elimination and decomposition of harmful gases.
