On Filtration Approach
IQAir's HyperHEPA filters particles down to 0.003 microns — impressive on paper. SCA's HEPA-Rx captures 99.97% at 0.3 microns, a clinically established benchmark. For practical particle capture across the range of airborne contaminants, both perform at very high levels. The bigger difference is the multi-stage system: SCA's 5-stage approach addresses particles, gases, AND pathogens — IQAir focuses primarily on particles.
