Stack the Carbon+ filter on top of your Pro Particle or SmokeStop filter for an added layer of activated carbon protection. The coconut carbon pellets absorb gases, including those caused by off-gassing, volatile organic compounds (VOC), smog, chemicals, and odors.

When it's time to replace your filter (about every six months), start by unplugging your air purifier. Remove the air intake grate on the right-hand side to access the filter. Pull the tabs on either side of the used filter together to close it like a book and remove it. Insert a new filter, opening it like a book inside in the air purifier - the sides should snap into place. Replace the air intake grate and plug back in. Easy.

Genuine Blueair filters are specifically designed to enable more air flow through the filter media. When combined with electrostatic filtration this results in faster cleaning than traditional HEPA filtration.

Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers.

This filter is compatible with the Pro M, L, & XL model.
The number of filters you need for replacement depends on your Pro model. Due to the modular design, the Pro M requires one replacement filter, Pro L requires two, and the Pro XL requires three. When you're ready to purchase, simply select your model at the top of the page and click 'Add to cart' - the proper quantity of filters will automatically add to the cart.
Pro SmokeStop filters feature highly-porous carbon pellets, extremely efficient at removing gaseous pollutants like odors, exhaust, smoke odors, and chemicals. The optional Carbon+ filter add-on stacks on top of the primary SmokeStop or Particle filter to provide additional chemical, gas, and odor removal.
Purchasing a filter subscription saves you 15% on all future replacement filter orders + free shipping and extends your limited 1-year product warranty to a lifetime warranty for as long as you remain a subscriber. At the time of purchase, the subscription will automatically schedule filter deliveries at the recommended six months. You can always adjust this timeframe from the 'My Account' section.
