Armstrong Air

These Armstrong aftermarket replacement whole-house media air cleaners are much more efficient than ordinary furnace filters. In fact, these media filters consistently outperform the competition, thanks to their highly-efficient synthetic material, featuring extended-surface pleats that have been proven to have a higher dirt-holding capacity than competitive filters.
