AllerAir 5000 Series prefilter 8-pack

Designed to pull noxious chemicals, fumes, and microbes directly out of the air, the AllerAir line of air filters features activated carbon derived from coconut shells. Despite its great efficacy when up against various pollutants, some compounds, particularly sticky oils and tars, that reduce the lifetime of these filters very, very quickly by coating the active surface area. As a result, protecting these filters with a tar-capturing pre-filter should be a priority for those who wish to extend the operational life of these particularly expensive filters.
