The Blueair SmartFilter is the most advanced replacement filter for HealthProtect™ 7300, 7400, and 7700 series air purifiers. Using HEPASilent Ultra™ technology, it efficiently combines electrostatic and mechanical filtration to capture 99.97% of airborne particles as small as 0.1 micron—including allergens, viruses, bacteria, dust, smoke, and pet dander.
Integrated with activated coconut carbon, it also removes odors, gases, and harmful VOCs. Equipped with a smart RFID chip, the filter accurately monitors usage and resets automatically when replaced. The dual-layer booklet design simplifies filter changes while trapping pollutants inside. Quiet, energy-efficient, and antimicrobial—this filter ensures cleaner air with less effort.
