The principle of high voltage electrostatic adsorption is used to remove particulate contaminants in the air, such as dust, soot, pollen, smoke and kitchen fumes. The disadvantage of this technique is that it is easy to produce ozone, and it is only effective for large particle gases such as particulate matter. Its disadvantage is the need to pay attention to electrical safety problems (high-pressure sometimes reach tens of thousands of volts), cleaning difficulties, and easy to produce ozone, must be properly designed to let the ozone emissions to the safe concentration below.
Ozone can be bactericidal, killing some virus bacteria at the same time may also kill human white blood cells, there is a possible cause of cancer. Therefore, generally not used for household air purification products. Ozone factor is mainly used to sterilize air, ozone is a world recognized efficient sterilization and detoxification oxidant, can effectively decompose all kinds of decoration contaminants, quickly kill all kinds of viruses and bacteria. Can meet just finishing and stage special static management, but because ozone has strong oxidation, will harm to people, accelerate the surface of the object aging, need to hint is this treatment method needs personnel to avoid, after 30 minutes after processing automatically revert to oxygen, is a green oxidation decomposition agent without any chemical residue.
Ultraviolet light is used to sterilize the ultraviolet lamp inside the machine, but it can also produce too much ozone. To achieve effective disinfection function must ensure a certain exposure time, air purifier general wind speed is greater, so ultraviolet sterilization capacity is limited, and the human body can not be received for a long time ultraviolet irradiation, the seal to be tight.
