Austin Air The National Sleep Foundation (NSF) Bedroom Machine

For people who want better quality sleep

The National Sleep Foundation (NSF) Bedroom Machine is the most advanced filtering system that Austin Air has ever designed. It was built to meet the requirements set out by the Johns Hopkins University Medical School for ongoing studies in which the filtering system must capture gasses and particles at the sub-micron level.

Every minute, over 250 cubic feet of air passes through 15 pounds of activated carbon and over 60 square feet of true medical grade HEPA, providing air so clean it could change how you sleep, which could change your life. If it doesn’t, Austin Air will refund your money within 30 days of purchase!

Due to the addition of a fifth level of fitration this unit does a superior job trapping pet dander, pollen and dust mites; chemicals like benzene, ammonia, dry cleaning solvents and other harmful toxins; and odors from cooking and other sources.

STAGE 1 - Large Particle Pre-filter
Removes particles easily seen by the naked eye (e.g. dust, hair, pet dander)

STAGE 2 - Medium Particle Pre-filter
Removes small to medium size particles (e.g. molds, spores, pollen)

STAGE 3 - Activated Carbon (15 lb)
Removes chemicals, gases and odors (e.g. sulfuric acid, ammonia), traps smoke and VOC particles.

STAGE 4 - Certified HEPA (60 sq ft)
Removes 99.97% of all particles larger than 0.3 microns

STAGE 5 - HEGA Carbon Cloth
The High Efficiency Gas Arrestance cloth removes chemical pollutants and provides an extra level of filtration before the purified air is sent back into the room.
