What are Blueair filters made of?

Standard HEPASilent™ filters incorporate non-toxic polypropylene filter media to trap particles and activated carbon filter media to remove gases. The optional SmokeStop filter adds more carbon for enhanced gas adsorption. The two filter options are otherwise identical in terms of particle filtering ability, filter life and size. Both polypropylene and carbon are recyclable. Polypropylene is a non-toxic fiber with ideal properties for use as a filter media.

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. Both standard Blueair system filters and advanced SmokeStop filters use activated carbon media; the optional SmokeStop filter has a higher carbon weight that enables it to absorb significantly more gases and odors.
