Blueair PRO XL SmokeStop™ Replacement Filter set

Replacement Smoke Stop filters for the Blueair Pro XL air purifiers. A combination particle and carbon filter, the Pro XL SmokeStop™ Filter is recommended for rooms with heavy gaseous pollutants, such as volatile organic compounds (VOCs) and cigarette smoke. Includes 3 SmokeStop V-shaped polypropylene filter for removing pollutants such as dust, pollen, bacteria, virus, pet dander, mold spores and other airborne particles down to 0.1 micron in size. Since polypropylene fibers are waterproof, Blueair purification systems do not require the use of chemical-based bacteriostats or mold inhibitors. Instead of absorbing the moisture in which bacteria thrive, polypropylene repels water and naturally prevents bacteria, mold and mildew from reproducing inside the filter. Replace filter every 6 months.
