Blueair 500/600 Series Replacement Filters (set of 3)

Filter Options
The Blueair Model 501 and Model 601 can use either the Dust & Pollen filters or the Smokestop filters. In either case, both models require a total of three filters and these three filters need to be changed every six months.

The Model 501 and Model 601 use three standard HEPASilent™ filters made of polypropylene (traps particles) and activated carbon (removes odors and gases), or three enhanced Smokestop HEPASilent™ filters made of polypropylene (with equal particle efficiency), including more activated carbon for better smoke and gas removal.
