Filters And Performance

Most Austin Air purifiers only come with 4-stage filtration, Austin Air Bedroom Machine lead the way with its 5-stage filtration that provides additional filtration against chemicals and odors. Targeting large contaminants is the mesh permanent filter and inner pre-filter while medium particles filter would obviously target medium-sized particles. Last stage 60 sq.ft. True HEPA filter would eliminate any contaminants that were not trapped by the previous filters. For smoke and odor related contaminants, Austin Air Bedroom Machine 15 lbs. Activated Carbon and Zeolite plus the added HEGA Carbon Cloth would ensure no chemicals would be flown back out in the air.

Austin Air Bedroom Machine is touted to be the best air purifier bedroom companion, the high 40 - 65 dB noise level should suggest otherwise as there is no sleep mode or auto mode to help with the speed adjustment. The best way to keep the air purifier from disrupting your sleep is to place it further back till you are comfortable with the noise generated. Power consumption like every other Austin Air purifier is at average 132 W.

^ Replacement filters/ estimated cost
Austin Air Bedroom Machine is the most expensive Austin Air purifier in its class. What you will get from the air purifier is the added filtration that would give you the extra protection against chemicals and allergens. Filter replacement cost is very cheap due to the bundled filter package that could last up to 5 years on normal condition. Replacing the filter is not easy but the good thing about the long filter lifespan is you will only have to replace the filter once every few years.
