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. The harmful particles 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. This technology does nothing for destroying particulate matter like PM2.5 or ultrafine particles, including VOCs. UV-C light also produces ozone which can be extremely toxic to our respiratory systems and general health.
Our patented 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. 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. DFS air purifiers are also certified with the Zero Ozone Verification by Intertek and are part of the Intertek Sustainability program. That means our air purification technology will fill your spaces with clean air without creating harmful ozone. You can find information about the certification by searching the Intertek Sustainability Directory.
