Blueair 503 Replacement Particle Filter
This is the replacement Particle Filter for the Blueair 503 air purifier.
This filter pack consists of 3 polypropylene HEPASilent filters, which are capable of trapping 99.97% of particles .1 microns and larger which pass through them including dust, dander, pollen, mold spores, bacteria, and other allergens and toxic materials.
The Blueair 503 purifier uses 3 filters at a time, so the replacement pack includes 3 replacement filters, which should all be replaced at the same time.
It is recommended that all Blueair Particle Filters be replaced every 6 months (with the exception of the ECO10, which should be changed every 12 months).
While the Particle Filters do include a pre-filter layer that incorporates a small amount of Activated Carbon, if smoke, odors, or gaseous chemicals are your concern, we highly recommend the Gas & Odor SmokeStop filters which feature a large amount of activated carbon pellets for dealing with these compounds specifically.
