| What are Blueair filters made of? Standard HEPASilent™ filters incorporate
nontoxic polypropylene filter media to trap particles and activated carbon filter media to
remove gases. The optional SmokeStop filter (501 Series only) 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 nontoxic 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 (501 Series only) has a higher
carbon weight that enables it to absorb significantly more gases and odors.
