HEPA-13 is medical-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.
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.

Right out of the box it was so easy to set up, understand the controls and settings. Within 24 hours both my wife and I felt that the air in the house us was cleaner and we had less dust. I moved the unit to the bedroom which Sans makes it so easy to move this unit with the attached top handel and my said that she felt that she was sleeping better. So, within one week using our first unit we purchased a second unit.
