The Austin Air Bedroom Machine (HM402) is Austin Air’s newest and most advanced air purifier, combining multiple proven filter technologies to offer a safe and effective solution for enhanced sleep and improved respiratory health. By using a sophisticated 5-stage filtration system, the Austin Air Bedroom Machine provides wide-spectrum air cleaning, removing not only airborne pollutants that are commonly found in the bedroom (e.g., dust, pollen, pet dander, mould spores, dust mite by-products), but the harmful chemicals and fumes produced by personal hygiene and grooming products (e.g., hair spray, deodorant, nail polish, makeup remover), dry cleaning, drapery, carpets and new furniture. The Austin Air Bedroom Machine air purifier is also highly recommended for handling the tough air quality issues that are typically found in bedrooms located in a basement or over a garage.

The Austin Air Bedroom Machine is the first air purifier to ever carry the National Sleep Foundation (NSF) name, and was recently selected for use in a John Hopkins Medical School study on the effects of bedroom air quality on asthma. In addition, the University of Buffalo has chosen the Bedroom Machine for a number of research studies on indoor air environments and asthma. Because of its high-performance air cleaning capabilities, the Austin Air Bedroom Machine offers a much-needed respite for allergy and asthma sufferers at night time, resulting in a more restful sleep and giving heavily-taxed immune systems a chance to recover.

The Austin Air Bedroom Machine air purifier features 5 different filtration stages to provide the ultimate protection against airborne hazards:

  • Stage 1 consists of a Permafilt pre-filter that removes large particles (e.g., dust, hair) from the air and is designed to preserve the life of the more expensive HEPA and carbon filters. The pre-filter can easily be vacuumed from the outside of the unit, making it simple to maintain and eliminating costly 3-month pre-filter changes.
  • Stage 2 consists of a medium particle pre-filter that removes small to medium sized airborne pollutants (e.g., pet dander, pollen, mould spores), providing further protection for the main HEPA and carbon filters.
  • Stage 3 features 15 lbs. of proprietary blended activated carbon, specifically engineered to remove chemical fumes, toxic gases and unpleasant odours.
  • Stage 4 consists of 60 sq. ft. of true medical-grade HEPA material to capture smaller particles (e.g., dust mite by-products, ultra-fine dust), removing 99.97% of all particles larger than 0.3 microns from the air.
  • Stage 5 uses a High Efficiency Gas Arrestance (HEGA) carbon cloth filter to provide added protection against any remaining chemicals and gases

One of the most convenient aspects of the Austin Air Bedroom Machine is that Stages 2 to 5 of the filtration system are encompassed in a single filter that only needs to be replaced once every five years.

The Austin Air Bedroom Machine features a perforated 22 gauge steel housing with a baked-on powder-coated finish to ensure there is no chemical off-gassing. A 360 degree air intake, with over 5 square feet of intake area, offers exceptional air gathering capability, while three fan speed settings and a louvered air flow output directed to one side from the upper deck allow for total user control. The Austin Air Bedroom Machine is also mounted on easy roll casters for increased portability and maneuverability.

The Austin Air Bedroom Machine air purifier is not only engineered for improved indoor air quality, but is specifically designed to advance the science of sleep. This unit is obviously perfect for the bedroom, but can also be used in living rooms, family rooms and single room apartments. The Austin Air Bedroom Machine is available in four attractive colours to easily blend into almost any décor.

“Wow. I put my new Austin Air Bedroom Machine in a 9 × 12 bedroom, and nothing can escape it. On the high setting, I got instant pharmaceutical grade air in a flash, and I can run it on high and still sleep fine. I love the Bedroom Machine in my small room, and the 360° intake makes it perfect for cramped quarters. I don’t have air conditioning, so I’ve been shopping for a good fan to get me through those handful of really hot nights. Now I don’t need one. In my small room, on high, the Austin Air Bedroom Machine is so powerful that the exhaust blows upward from the louvered manifold, bounces off the ceiling and swirls around, keeping me nice and comfortable. This is the perfect air purifier for my needs.”
P. Zimmer, Toronto, ON

“I’ve enjoyed our Austin Air Bedroom Machine very much, and that’s why I’m buying another unit for my new house that has one more room.”
S. Chou, Surrey, BC

“The Austin Air Bedroom Machine that we purchased from you is working great. We now use it in the bedroom. We find that the air purifier works great on gaseous smells like smoke, barbecue, fireworks etc., but not as well on perfumes, sweet smells or cooking odours. However, we are very happy that it does what it does. Thank you for all of your help.”
R. Blair, Toronto, ON

** An Important Word on Air Flow Rates and Room Coverage for the Austin Air Bedroom Machine Air Purifier:

Many retailers and manufacturers overstate maximum room coverage figures by calculating them with air flow rates measured without filters installed (i.e., fan output) or with too low a number of air exchanges per hour to properly clean the room. Modern Alchemy Air Purifiers believes in stating the actual delivered air flow rates for the air purifiers we sell, as well as realistic room coverage figures calculated at effective air cleaning levels. Accordingly, we recommend that the Austin Air Bedroom Machine be used in rooms of up to 235 sq. ft. (for premium cleaning) or 470 sq. ft. (for general purpose filtration).

Also note that air purifier performance should not be judged by air flow rates and room maximums alone. Many features that make an air purifier more effective at cleaning the air actually reduce the air flow rate. For example, higher grade HEPA filters, well-sealed filtration systems and large amounts of carbon all increase air resistance and reduce delivered air flow rates.
