Blueair 603 Replacement SmokeStop Filter

This is the replacement Gas & Odor SmokeStop filter for the Blueair 603 air purifier.

This filter pack consists of 3 SmokeStop filters, which offer the same advantages of the Particle Filters by trapping 99.97% of particles .1 microns and larger that pass through them including dust, dander, pollen, mole spores, bacteria, and other allergens and toxic materials.

The Gas & Odor SmokeStop filters incorporate a large amount of Activated Carbon pellets, which serve to adsorb gaseous compounds in the air that may be contributing to offensive odors in the home or negative health effects. The filter contains 2 lbs of coconut shell activated carbon impregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI).

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 you replace your Blueair SmokeStop filters every 6 months.
