What does UVC do in an air purifier?

What are UV light air purifiers? UV air purifiers are designed to use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mold, bacteria and viruses. They have the same ultimate goal of all air purifiers: to reduce indoor air pollutants.

Is UV-C safe in air purifiers?

Other health experts state that electric air purifiers, such as electrostatic and UV light-emitting purifiers, create ozone gas. In addition to these types, ionizers and hydroxyl generators also produce ozone gas. The specialists warn that these types of filters can create potentially hazardous indoor air pollution.

Are air purifiers with UV light worth it?

Short answer: No. Don’t buy a UV light air purifier or any air purifiers that use UV light as a key part of their purification mechanism. It’s dangerous and doesn’t work that well, especially without the use of other proven air filtration methods.

Do UV-C air purifiers produce ozone?

The danger comes from oxygen particles that are broken apart by the high-energy UV-C light. These atoms then combine again with other oxygen atoms to form ozone. Therefore, UV-C air purifiers are not ozone-free. Not only do they produce ozone, they are not very effective in a residential setting.

Does UV-C light produce ozone?

Some UVC devices also produce light in this wavelength. … The reason for this is that the shorter (185 nanometers) wavelength of UVV light actually generates ozone. This occurs because UVV light reacts with oxygen to break it into atomic oxygen, a highly unstable atom that combines with oxygen to form O3 (ozone).

Do UV air purifiers work on viruses?

And long enough exposure to the UV light in an air purifying device can disable some viruses, including COVID-19.

Which is better air purifier or UV light?
