HEPA-13 is medical-grade purification technology that traps 99.97% of particles down to 0.3 microns, and 99.95% of particles down to 0.1 microns in diameter.
Filters with a lower HEPA number (e.g. HEPA-11 and True HEPA) 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.
