The BISSELL™ air400 Air Purifier is clean air made easy. We know life happens. Between the kids and pets, there are odors, allergens, dust, and other things we can’t always see in our air that needs to be cleaned. That’s where air400 shines. This machine is designed to perform from the inside, out. It captures airborne particles and odors with three stages of filtration and has an automated CirQulate™ System that automatically increases fan speed as your indoor air quality decreases. The air400’s CirQulate™ System also uses particle sensor technology to monitor your indoor air and communicate your home’s real-time air quality through three distinct colors and a numerical reading. With a large fan and a digital, 20,000-hour DC motor, the air400 can filter the air in a 1200 sq. ft. room once every hour. Taking care of the air you and your family breathe really is as easy as setting it and forgetting it with the air400 air purifier.

  • Automated CirQulate™ System uses a PM 2.5 sensor to monitor, report and respond to changes in your indoor air quality by adjusting fan speed as necessary.
