Completely filters air in 550 ft² room every 12 minutes.

Designed for large rooms: Filters the air at a rate of about 5x an hour (or about every 12 minutes) in a 550 ft² room to effectively lower particle levels and help maintain a comfortable environment in your large living room, family room, or playroom.

Clean air at the touch of a button: The one-touch enabled Auto mode is designed to help you maintain a comfortable home environment. When enabled, the setting automatically adjusts fan speed based on real-time conditions reported by the integrated particle sensor. Stay up to date on your air quality with the LED display; it changes color to indicate good, moderate, or poor.

Three-part filtration: A fabric pre-filter offers the first layer of protection, catching large particles and extending the life of the primary filter. The combination Particle + Carbon Filter uses a layer of activated carbon to filter light household odors from pets, cooking, and smoking, while the main particle filter removes airborne particles, like pollen, dust, pet dander, and more.
