• Designed specifically to fit the original Blueair Sense and new Blueair Sense+
• Anti-shedding and chemical free meaning free of chemicals and binders and ultrasonically bonded to prevent new particles from being added to your environment.
• HEPASilentPlusTM technology: ur Sense Filters feature next generation technology, capturing 99.97% of harmful particles from the air down to 0.1 micron in size, with an added sheet of activated carbon. Fortified with a blend of Potassium Hydroxide (KOH) and Potassium Iodide (K1), the activated carbon traps odors, tobacco smoke, and dangerous VOCs.
• Naturally antibacterial: The polypropylene fibers in our filters are naturally waterproof and antibacterial to prevent bacteria and mold growth, so you'll never add harmful particles back into the air.
• Whisper silent delivery: Using a combination of both electrostatic and mechanical filtration, Blueair filters are able to use less dense filter media. This means less effort is required to push the air through the filter, resulting in peak performance levels with whisper silent delivery.
