few people know the difference between air purifiers and ozone generators, even including many manufacturer, if you want to know details, please attention to following content
1. Air purifiers filter solid pollutants (PM10, PM2.5, and other solid particulate matter) and gaseous pollutants (ammonia, volatile organic compounds TVOC, etc.) in the air
2. The ozone generator is used to generate ozone for sterilization, deodorization, mildew removal, etc.
The difference between the two is as follows
1. Air purifiers are mainly used to filter pollutants in the air (including some bacteria)
2. The ozone generator is specialized in producing ozone to kill bacteria, viruses and other microorganisms
Why can air purifiers be easily sterilized?
When the air purifier based on the principle of static electricity and ultraviolet light works, static electricity will ionize oxygen in the air to generate oxygen atoms, and oxygen atoms and oxygen quickly generate ozone, while ultraviolet light, with a wavelength of 100-200nm, photolyzes oxygen to generate oxygen atoms, oxygen atoms and oxygen. Quickly generate ozone, which is the principle of ozone sterilization in air purifiers. Note that the ozone concentration here is particularly low because of the way it is generated, so the air purifier can only reduce microorganisms and bacteria in the air, which cannot meet the standard of sterilization. The air purifier works continuously for 24 hours in a specific environment and is tested at a distance of 50mm from the air outlet. The ozone concentration cannot be greater than 0.05ppm, which is the national standard of ozone concentration for air purifiers in China. (In the air, the concentration of ozone is 1ppm=2.14mg/m3)
The core difference: Air purification is mainly to passively filter the air through physical means. When the indoor air does not flow through it, it has no effect. Ozone-type air purifiers, ozone is the active sterilization of gas with the flow, which can sterilize any corner, and can Deodorant.
When buying an ozone air purifier, pay attention to choosing suitable ozone quantiry according to the size of your room, space or car etc. Usually for car, refrigerator for food presevation, bathroom, ozone machine's o3 production 3mg/hour is enough
