Blueair Advanced SmokeStop filters use activated carbon media that has a higher carbon weight that enables it to absorb significantly more gases and odors than the regular Blueair filter Polypropylene is central to the electrostatic filtration component of the Blueair system. Polypropylene molecules readily orient to an electric field. That is, the molecules "feel" a charged particle enter the filter media and turn toward it. This creates a high attraction force, which acts in turn to draw the particle toward the polypropylene fiber where it can be captured. When compared to standard filter media made of triclosan-coated paper or glass fibers, polypropylene is an ideal material. Because polypropylene is waterproof, Blueair systems need no chemical-based bacteriostats or mold inhibitors. Instead of absorbing the moisture in which bacteria thrive, polypropylene repels water and prevents bacteria, mold and mildew from reproducing inside the filter. Thus, your family can avoid the potential adverse health effects of chemical additives. Activated carbon adsorbs odors, fumes and other gaseous pollutants implicated in a host of illnesses related to indoor air pollution.
