DREO Smart HEPA Air Purifier for Rooms Up to 1500 Sq.Ft/2H, Purifier for Allergies and Asthma with PM2.5 Display, 3-in-1 Filter, 25 dB Sleep Mode, App & Alexa/Google Compatible

Instant Room-Filling Freshness With 102 CFM CADR, this purifier moves a high volume of filtered air for quick, visible improvement. It refreshes a 158 sq. ft. room approximately 4.8 times per hour, and covers up to 758 sq. ft. for larger spaces. The bottom-intake, top-outlet design circulates air upward, filling the room with fresh, clean air. 3-Stage True HEPA Filtration The H13 HEPA filter captures 99.97% of particles down to 0.3 m (pollen, fine dust, mold spores). The pre-filter traps hair and lint to extend filter life, while the 30 g activated carbon layer helps reduce odors, VOCs, and smoke. Together, they deliver cleaner, fresher air for allergy-prone households. Auto Sensing & Air Quality at a Glance The built-in PM2.5 sensor continuously monitors air quality and auto-adjusts the fan speed as pollution levels change. The numeric PM2.5 readout and 4-color indicator light (blue/green/yellow/red) provide instant, clear air quality updates. Enjoy true set-and-forget operation that keeps your air clean without constant adjustments.
