- UV light purifiers use UV-C light, also known as germicidal light. It harms cells by destroying nucleic acids and disrupting their DNA, which either kills them or leaves them incapacitated. Cells have to be exposed to UV-C light for long periods of time for this to work.
- UV-C light is only effective at disinfecting surfaces and is not effective at destroying pollutants in the air. It does nothing for destroying particulate matter like PM2.5 or ultrafine particles.
- UV light is only effective at killing some pollutants and unfortunately can't kill VOCs at all.
- Lastly, UV-C light produces ozone which can be extremely toxic to human health and cause respiratory symptoms and health issues.
- DFS technology has been studied and proven to remove 99.99% of airborne particles down to 0.007 µm in size. It uses a self‐contained, highly-energized state in the main filter that clusters ultrafine particles together to make them larger, allowing the main filter to effectively capture ultrafine particles.
- Next, the controlled, isolated high energy field generated by the DFS continually creates high energy exposure through the pleats and fibers of the main filter. This prevents organism growth in the main filter and prevents live organisms from escaping back into the air.
- These two mechanisms work together to provide ultraclean filtration of particles.
- Lastly, DFS air purifiers are certified with the Zero Ozone Verification by Intertek and are part of the Intertek Sustainability program. You can find information about the certification by searching the Intertek Sustainability Directory.
