Photocatalytic oxidation (PCO): Some air purifiers use ultraviolet radiation as well as a photocatalyst, which include titanium dioxide, to generate hydroxyl radicals that oxidize gaseous pollutants. patriot air purifier Depending on the pollutant, this reaction can crank out hazardous byproducts, which include ozone, formaldehyde, nitrogen dioxide, and carbon monoxide. CR does not at this time check air purifiers with PCO technology. There happen to be handful of discipline investigations Checking air purifier for nose out the success of PCO air purifiers, but one laboratory analyze, conducted by researchers at Syracuse University in Big apple, noted which the units did not correctly take out any of the VOCs commonly located in indoor air.
The Dyson also has one of the most sophisticated onboard air screens we’ve observed on the purifier.
