HEPA is professional-grade purification technology that traps up to 99.97% of particles down to 0.3 microns, and up to 99.95% of particles down to 0.1 microns in diameter.

Air purifiers that don't use HEPA often aren't as good at trapping particles, which means there are more contaminants in the air you're breathing at home.

Activated Carbon is a critical component of effective air purification, catching harmful chemicals such as Formaldehyde and Volatile Organic Compounds (VOC). The Carbon filter in Sans also captures odors, smoke and other gasses, such as radon.
