The 402 replacement filter for the Austin Air Bedroom Machine is nothing short of a beast. There are 5 (count them) stages of filtration in this filter.
Large Particle pre-filter removes large visible particles from the air (e.g. pollen and pet hair).
Medium Particle pre-filter (removes small to medium size particulates from air).
15 lbs. of carbon blend (removes gases from air).
60 square feet of certified HEPA (removes small particulates from air).
HEGA carbon cloth (removes gases from air).
To summarize: If this filter removed anything else from the air we’re afraid there would be nothing left to breathe!
