This Air purifier is mainly used to remove the odor of space. It is suitable for space deodorization and sterilization to a certain extent in bedrooms, living rooms, hotels, guesthouse, elevator rooms, cars, pet house, kitchen, toilet, cabinets, wardrobes, shoe cabinets and other places where bacteria are easy to breed and the odor is heavy. Function Through the "hydroxyl radical" space purification, deodorization, sterilization and disinfection, achieve air purification function. Operating Principle The effect of hydroxyl radical on bacteria is to destroy the cell wall of bacteria, and spread into cells, oxidative decomposition of bacteria internal active enzymes, nucleic acids, proteins, lipids and polysaccharides, so that the metabolism and reproduction process of bacteria is destroyed, resulting in cell lysis and death. The effect of hydroxyl radical on the virus is to destroy the virus and capsid protein and then oxidative destruction of viral RNA or deoxynucleic acid, so that the virus lost the ability to deposit, reproduction. Hydroxyl radical have very strong oxidation, catalytic and bactericidal abilities. And the byproduct of the whole process is only water and oxygen, almost leaving no residue, is internationally recognized pollution-free, no dead corner the cleanest disinfection way. Hydroxyl radical can decompose formaldehyde, benzene, methane, ammonia and other harmful gases rapidly.
