Dayton air purifiers are designed to keep indoor air clean and safe from odour, dust and bacteria and also control humidity in commercial and manufacturing facilities. These portable units feature high frequency plasma technology that efficiently reduces / eliminates contaminants and harmful particles (like dust, smoke and pollen) to enrich oxygen content and freshen air. They use a combination of three filters which are pre filter, HEPA and activated carbon along with dust and odour sensors to nearly eliminate indoor air contamination up to 99.7 percent efficiency. Selected models feature a TiO2, photocatalyst filter that operates under a UV bulb for controlling harmful VOCs (volatile organic compounds). Choose from a broad range of these air cleansers, available in 26 and 68 dBA sound levels.
