Description

Levoit air purifiers avoid using uv-c light, an air cleaning method that research has shown can produce harmful ozone and secondary pollution. Please follow the details and faqs below. Q: how safe are uv purifiers? the biggest issue with uv purifiers is that they emit varying levels of ozone. Even very small amounts of ozone in the air may result in chest pain, coughing, shortness of breath, and throat irritation. In fact, the world healthorganization (who) has issued a warning against people using uv light to sterilize their hands or any other part of their skin. Q: how effective are uv purifiers? not very. Microbes have to spend some time in front of the uv light before they’re destroyed. The epa explains that microbes must be exposed to the light “on the order of minutes and hours rather than the few seconds typical of most uvgi air cleaners”.
