On Filtration Philosophy
Austin Air's HealthMate Plus is built around 15 lbs of activated carbon + zeolite for gas and VOC adsorption — significantly more carbon mass than most portable units. SCA splits its carbon across two dedicated stages augmented with potassium permanganate (which oxidizes VOCs the carbon misses). For pure VOC volume, Austin Air has a real advantage. For balanced multi-stage treatment that also actively destroys captured pathogens, SCA's approach is more comprehensive.
