See a brief video showing Austin Air HEGA Filtration:

The Austin Air Baby's Breath HEPA/HEGA Air Purifier (HM205) is the only home air purifier designed just for babies. This small, but robust air cleaner will keep your baby's air free of dust, allergens, and airborne microbials, like mold spores, viruses, bacteria, and even fungus. Not only that, Baby's Breath will remove both harmless and harmful odors, vapors, gases, VOCs, and any gaseous toxin that you don't want your baby breathing in. Using Austin Air's advanced HEPA/HEGA filtration system, Baby's Breath will give your baby the cleanest, freshest, and safest air. Like all Austin Airs, Baby's Breath is simple (no electronic extras), yet extremely effective at doing what it's designed to do best – remove abundant amounts of particulate matter, gaseous odors, chemical vapors, and harmful VOCs from indoor air.

Austin Air was founded in 1990 in Buffalo, New York by a husband trying to help his wife find relief from lifelong asthma symptoms, which he did with the Austin Air HealthMate. Today, Austin Air continues to operate out of Buffalo, and husband (now president) Richard Taylor and crew continue to build air purifiers with a "family first" mentality, knowing that cleaner air can benefit all those affected by respiratory issues.

Why Austin Air?

  • Superior Filtration ‐ Particles, Gases, Odors and VOCs

    Most Austin Airs, including Baby's Breath, provide 4 stages of intense filtration (5 stages with the Bedroom Machine). What makes Baby's Breath unique is its filters and filtration process. Two pre-filters begin by removing larger particles – one wrapped around the interior of the unit's housing, the other surrounding the HEPA filter. Next, comes 30 square feet of True Medical-Grade HEPA filter media (to trap sub-micron particles). Following the HEPA is an advanced military-grade HEGA carbon cloth filter (to trap odors, gases and VOCs).

    Unlike typical carbon filters (which sit before the HEPA), Austin's advanced HEGA carbon cloth releases no carbon dust when air passes through it, so can be placed after the HEPA. This sequence means air passes through the HEPA before passing through the HEGA carbon filter, leaving the total surface area of the carbon filter available solely for gas, odor and VOC removal. This design not only maximizes the performance of each filter, but also increases the usable life of the HEGA carbon filter and decreases the weight of the filter assembly from 8 lbs to 2.5 lbs.

    No other air cleaner in its class can match the performance of a Baby's Breath. It simply "out filters" other brands. Austin Air backs this up by providing a 5-Year Pro-Rated Filter Warranty, in addition to its 5-Year Mechanical Warranty.

  • Designed for Performance

    Austin Air junior models, including the Baby's Breath, process 125 cubic feet of air every minute (250 cubic feet for standard-size models). Air is drawn in from all sides of the unit via its 360° air intake grilles, where it immediately begins to be pulled through Austin's 4-stage or 5-stage filter, which progressively removes dust, hair, fibers, odors, gases, VOCs, Radon daughters, pollen, pet dander, mold spores, bacteria, viruses, and other allergens and contaminants.

    Austin Airs feature high-velocity airflow (50-200 cfm for junior sizes, 75-400 cfm for standard sizes), which helps to quickly create a pocket of clean air around the user. Run on high with the door closed, and assuming four air changes per hour, Austin Air junior sizes can clean a 480 sq ft room in 30-40 minutes (or a 465 sq ft room in 15-20 minutes for standard sizes).

    Austin Airs produce 50-66 dBA (decibels) of noise, depending on fan speed selected. Customers report it to be very quiet on the low setting. Set at high, the sound approximates that of a normal conversation. Many customers use the high setting for quick or maximum air cleaning.

    Austin Airs are solidly made. Each unit is built using 22-gauge welded steel that does not rattle or vibrate, even at max speed. A powder-coated finish (baked at 375°F) does not off-gas and lends durability. Standard-size models come equipped with heavy-duty casters for easy portability. Casters are optionally available for Junior-size models.

    Austin Airs save energy. Energy efficient PSC motors, equipped with a centrifugal fan, use less energy than some light bulbs. Electricity to run a junior-size model, such as the Baby's Breath, at max draw (82 watts) costs about 1 cent per hour, and about 1.5 cent per hour to run a standard-size model at max (132 watts), based on average residential electricity rates projected by the United States EIA for 2014-2015. Energy costs for each will be less when run on the lower fan speeds.

  • Made in USA

    Austin Air produces everything here in the USA out of its 480,000 square-foot facility in Buffalo, New York – the largest air cleaner manufacturing facility in the world. While made on American soil, Austin Airs can be found helping people in homes throughout the world. Austin Airs are also used in hospitals and clinics, and have even been called to national service by the U.S. Army Corps of Engineers, and to assist FEMA and the Red Cross in the aftermath of 9/11. When clean air is crucial, and lives depend on it, Austin Air remains the #1 choice.

  • Integrity in Claims about the Product and Test Results

    Austin Air believes in being straight with consumers about what its products can and cannot do. The company does not use private testing, but rather each air purifier undergoes tough government and third-party testing, whose stringent standards must be met to ensure products perform as claimed. For example, wide-ranging product tests conducted by Battelle Laboratories (a well-respected testing laboratory for the Army Corps Engineers at the U.S. Army Aberdeen Test Center) have included flow design and rate, as well as gas, odor and sub-micron particle removal.

  • Ease of Use and Low Maintenance

    Austin Airs come ready to be plugged in. Each unit comes with two filters ‐ the outer pre-filter, and the HEPA filter assembly. All models use a manual rotary dial to switch between 3 fan speeds ‐ High (III), Medium (II) and Low (I). Austin Airs can be placed anywhere in a room, but should be at least 4-8 inches from a wall for maximum effectiveness.

    Austin Air filters are designed to last five years, which saves on the hassle and cost of frequent filter replacements. If filters do need to be replaced, the process is straightforward and should take only a few minutes. Although the bottom cover must be removed using a Phillips-head screwdriver (4 screws), filters just lift out for easy replacement. The outer surface of the units need only be vacuumed monthly to remove dust particles that may accumulate on the exterior air intake grilles.

  • 700 sq. ft. (1 air change per hour)
  • 480 sq. ft. (2 air changes per hour)
  • 300 sq. ft. (3 air changes per hour)

Austin Air Baby's Breath Instructions

Please see Owner's Manual tab for setup and operating instructions, plus full instructions on changing the filters. A one-page set of instructions on filter changes is also provided.

General on Pre-Filter:

  • The outer Stage 1 pre-filter (which you can see can through the unit's perforated grille) can last for years with regular cleaning. Just vacuum the outer surface of the unit monthly (you do not need to open the unit) by using the brush attachment of your vacuum to remove dust from the outside of the unit and large particles from the pre-filter.

  • If you do not maintain the outer Stage 1 pre-filter or if it becomes damaged, genuine Austin Air replacement filters are available through National Allergy.

General on HEPA Filter:

  • Austin Air filters are designed to last up to 5 years. However, please remember that the filter's service life is related to the volume of air that passes through the air purifier and the amount of contaminants in the air. If your indoor air has an unusually high level of airborne particulates, smoke or gaseous contaminants, the filter's service life may be shortened.

  • Regular maintenance helps to prolong the life of the HEPA filter. Keep the area surrounding the air purifier clean, and be sure to vacuum any dust buildup on the outside of the unit, especially on the 360° air intake grille.

  • Replace the HEPA filter pack if you notice a significant drop in clean, odorless air flow.

  • Important ‐ For first-time use or any time you change the HEPA filter pack, it is important that you run the purifier on the High (III) setting for at least the first hour of use. After the first hour, turn the Speed Control Setting to the desired level.
