Blueair Classic 500/600 Series DualProtection™ Filter Kit

(Replaces the Old Classic 500/600 Series Smokestop Filters)

This filter kit comes as a set of 3 filters. All 3 filters are installed at the same time in the purifier.

The DualProtection filter is designed with high-porosity coconut carbon to efficiently removes gaseous pollutants like PM 2.5, VOCs, traffic exhaust, smog, smoke, odors and airborne chemicals faster compared to other carbon filters, to prevent them from ever building up.

Blueair Classic 500/600 Series DualProtection™ Optional Filter is designed to remove a larger range of impurities from your indoor air when installed inside the traditional Blueair Air Purifier. Each model has its own size filter so be sure to check your model number or contact us for verification.
