Breathe easy and sleep soundly with the Austin Air Bedroom Machine Air Purifier – also known as the National Sleep Foundation Bedroom Machine. While you sleep, this air cleaner rids the air of common allergens and odors that trigger allergy and asthma symptoms and heighten multiple chemical sensitivities (MCS). Designed to clean the air in spaces up to 1,500 square feet, the Bedroom Machine captures nano-sized particles and absorbs harmful odors and chemicals, so you can rest easier.
The Austin Air Bedroom Machine Air Purifier:
The Austin Air Bedroom Machine—also known as the Austin Air HM402 Air Purifier—uses Austin Air's signature 360-degree progressive filtering system to remove the most symptom-aggravating allergens, odors, and chemicals from your home. With steady use, you'll get relief from your symptoms or even eliminate them all together both during the day and while you sleep. Every minute, the system pulls in room air from all sides of the air cleaner. Air passes through a 5-stage HEPA/carbon combination filter and is blown back out into your room using the Clean Air Pocket vent. This extensive filtration system cleans your air faster and more efficiently than conventional air purifiers, which means quicker relief from your symptoms.
The Bedroom Machine Air Cleaner 5-stage combination filter includes:
Overall, this long-lasting combination filter eliminates 99.97% of airborne pollutants that are 0.3 microns and larger, 95% of particles that measure 0.1 micron and smaller, and more than 3,000 types of toxic gases and odors. You'll rest easy knowing that you and your family are breathing the cleanest air possible.

Made in the USA, the Austin Air Bedroom Machine Air Purifier is constructed with sturdy, long-lasting components that boost efficiency and energy savings. These include an energy-efficient Permanent-Split Capacitor (PSC) motor, a powerful centrifugal fan, and an all-steel outer body. The long-life PSC motor is rated for continuous use at high RPMs and is mounted on shock absorbers to minimize noise. When running, the Bedroom Machine's motor draws less current and reduces your operating costs by 50% when compared to other air purifiers.
