Austin Air Allergy Machine HEPA/HEGA Air Purifier – HM405

See a brief video showing Austin Air HEGA Filtration:

The Austin Air Allergy Machine HEPA/HEGA Air Purifier (HM405) helps those combating allergy and asthma-related problems who are also exposed to higher levels of smoke, cooking odors, chemical vapors or VOCs that can trigger or worsen symptoms. The Allergy Machine uses True Medical-Grade HEPA for extreme particle filtration, plus an advanced military-grade carbon cloth for high-efficiency HEGA filtration of gases, odors and VOCs. Customers using the Allergy Machine often remark on the abundant quantity of clean air it produces, and how they can really “feel” the difference in better breathing, reduced symptoms, and less waking up at night. Like all Austin Airs, this no-nonsense machine is simple (no electronic extras), yet very effective at doing what it’s designed to do best – remove copious 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 the Allergy Machine, provide 4 stages of intense filtration (5 stages with the Bedroom Machine). What makes the Allergy Machine 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 60 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 21 lbs to 8 lbs.

  No other air cleaner in its class can match the performance of the Allergy Machine. 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 machines process 250 cubic feet of air every minute (125 cubic feet for the junior 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 (75-400 cfm for standard-size units, 50-200 cfm for junior 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 Airs can clean a 465 sq ft room in 15-20 minutes (or a 480 sq ft room in 30-40 minutes for junior 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 standard-size unit at max draw (132 watts) should cost about 1.5 cents an hour, and about 1 cent an hour to run a junior-size unit at max draw (82 watts), based on average residential electricity rates projected by the United States EIA for 2014-2015. Energy costs for each size 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.

The Allergy Machine provides clean air in rooms up to a maximum of:

• 1500 sq. ft. (1 air change per hour)
• 875 sq. ft. (2 air changes per hour)
• 600 sq. ft. (3 air changes per hour)
• 465 sq. ft. (4 air changes per hour)
• 375 sq. ft. (5 air changes per hour)
• 315 sq. ft. (6 air changes per hour)
