The AD4000 air purifier is designed to improve indoor air quality. It rapidly cleans up to 2,776 sq ft, making it ideal for large rooms, basements, and other larger spaces, using a fully sealed filtration system with a Pre-Filter, Premium Carbon/VOC filter, and UltraHEPA filter. UltraHEPA technology captures 99.99% of airborne particles at 0.003 microns, while the Premium Carbon/VOC filter helps reduce odors, smoke, gases, VOCs, and other everyday household pollutants. Auto Mode and real-time air quality monitoring help maintain cleaner air throughout the day. Genuine AirDoctor filters are recommended to maintain optimal performance.
