Unlike most most air purifiers that collect airborne contaminants in their expensive filters or ionic ones that produce harmful ozone levels, the NanoBreeze - Filterless Nanotechnology Air Purifier is a literal breath of fresh air because it destroys viruses, bacteria, mold spores, pollen and more, removes odors and dissolves toxic vapors and gases from the air on the spot using nanotechnology (see below). Plus it's a great 3-speed fan as well! So, if you are going to run a fan that circulates air, it might as well eliminate all these unwanted air impurities as well.
How Does it Work?
"Nanotechnology is the design, manufacture or control of single molecules to perform the duties of a machine and involves man-made materials so small, they are measured on the scale of a nanometer. Titanium dioxide (TiO2) crystals, only 40 nanometers in size, form a molecular machine powered by light. TiO2 is a semiconductor charged by ultraviolet photons. When these nanoparticles are charged, powerful oxidizing agents called hydroxyl radicals are produced. These free radicals destroy airborne germs and pollutants that circulate over the surface of the patented light tube inside the NanoBreeze Room Air Purifier. Airborne pollutants are then turned into water (H2O) and carbon dioxide (CO2) through reduction and oxidation reactions." (Source)
