Austin Air Bedroom Machine Air Purifier

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® is the ideal air quality improvement device for - you guessed it - your bedroom. The Bedroom Machine® is designed to give you the ultimate protection against allergens, viruses, bacteria, chemicals and VOC’s. The results of two separate clinical trials show this unit to be highly effective at removing dangerous airborne pollutants from the home. Keep the air in your bedroom free from pollution and get the good night’s sleep you deserve. The Austin Air Bedroom Machine Air Purifier:
  • Features the highest level of filtration in any Austin Air purifier

  • Removes dust, pollen, tobacco smoke, chemical vapors, gases, viruses, bacteria, and more

  • Uses a 360-degree filtering system that draws air in from all sides of the unit and passes it through a 5-stage filter for the most thorough air filtration

  • Traps 99.97% of particles as small as 0.3 microns and 95% of particles that measure 0.1 micron and smaller

  • Generally requires a filter replacement only once every 5 years

  • Needs minimal routine maintenance


Relieves Overnight Allergies, Helps You Sleep Better

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:

  • PERMAFILT Pre-Filter - During stage 1, air passes through a cotton PERMAFILT pre-filter, which captures particles easily seen by the naked eye, such as large dust and pet dander particles.

  • Medium Particle Filter: Next, a medium particle filter traps small- to medium-size allergens, such as mold, pollen, and dust mites.

  • Carbon Blend Filter: Next, air moves through a 15-pound carbon and natural zeolite filter where odors, chemicals, gases, fumes, and VOCs are absorbed and locked away.

  • Medical-Grade HEPA Filter - Next, air glides through 60 square feet of true medical-grade HEPA (High Efficiency Particulate Air) material where it is scrubbed free of harmful bacteria and viruses as well as smaller pollen, mold, pet dander, dust, and ragweed particles.

  • HEGA Filter – During the final stage, a HEGA (High Efficiency Gas Absorption) filter constructed of military-grade activated carbon cloth absorbs chemicals, gases, fumes, vapors, and odors. HEGA filtration is particularly effective in removing harmful volatile organic compounds (VOCs).

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, allergen-free air possible.


Durable Construction for Years of Clean Air

Made in the USA, the Austin Air Allergy 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 Allergy Machine motor draws less current and reduces your operating costs by 50% when compared to other air purifiers.
