Airpura P600 Plus Air Purifier The Airpura P600 has all the great features of the P600 and also features a premium titanium dioxide coated surface area. This is the VOC Chemicals Air Purifier Black with Photocatalytic Oxidation. The specially coated HEPA filter offers an additional 3 times the photocatalytic capacity to deal with especially heavy concentrations of airborne chemicals. The P600 uses the latest discoveries in nano-technology to deliver a new and speedy airborne chemical abatement process. The TitanClean Titanium Dioxide Photo-Catalytic Oxidizer dramatically increases the range of dangerous airborne chemicals that can be neutralized safely and effectively. TitanClean's titanium dioxide TiO2 coating in conjunction with the UV light, creates an oxidizing process that instantly breaks molecular bonds and reduces airborne chemicals to smaller safer compounds, until carbon dioxide and water vapors are left. The TitanClean Photocatalytic Oxidizer is combined with Airpura's 18 lb Activated Carbon bed, true Hepa Filter and 20 watt UV Germicidal Lamp to deliver the most complete air cleaning system available today. Rids your air of formaldehyde, molds, radon, ammonia, mercury vapor, benzene, aldehyde, pesticides, butanol, carbon monoxide, exhaust fumes, PCBs, sulfur oxides, toluene, nitrous oxide, chloroform, dioxane, chlorotoluene, and trichlorophenol. Warranty 5 years parts and 10 years labor manufacturer's warranty. Titanium Dioxide Photocatalytic Oxidization Developed and used in space technology laboratories for both air and water purfication A metal surface coated with a metal oxide is irradiated with UV light to produce hydroxyl radicals and super-oxide ions The hydroxyl radicals and super-oxide ions break the molecular bonds of chemicals they come into contact with and slice them into smaller compounds, that are further broken down until only carbon dioxide and water vapor are left For maximum efficiency, the process requires a suff This item ships from a separate warehouse and may require extra time for delivery.
