The Five Stage Air Cleaner.

Using a robust five-stage cleaning process to remove fine dust, pollen, odors, viruses, and bacteria, this is the most comprehensive air cleaning system available. Its first and second stages use an activated carbon and HEPA filter to remove fine dust, pollen, soot particles, and odors such as smoke or food. A plasma generator in the third stage reduces mold spores, pollen, dust mites, microbes, viruses, and bacteria. The fourth stage uses a UV light that irradiates a matrix of titanium dioxide to fully destroy bacteria, viruses, and mold spores. The final stage uses negative ions to bond positively-charged air molecules such as dust and smoke, refreshing the air, yet is completely ozone-free. It operates at 14 watts and has a quiet fan that only generates 26 decibels. Performance tested by TÜV of Cologne, Germany, world-renowned safety testers of industry materials since 1876.
