Frequently Asked Questions

Sans Technology

SmartPure is our proprietary technology for measuring the air quality in your space and giving you real-time insight into this number. Precise sensors constantly monitor your air quality and our digital display allow you to view your AQI (Air Quality Index) at a glance.

HEPA-13 is medical-grade purification technology that traps 99.97% of particles up to 0.3 micron, and 99.9% of particles up to 0.1 micron in diameter.

Filters with a lower HEPA number (e.g. HEPA-11) 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).

Sans produces no ozone and is completely safe. Air purifiers that produce ozone can be dangerous and should be avoided.

The UV-C light featured in Sans sterilizes airborne viruses and bacteria so you're not breathing them in.

This technology paired with our HEPA-13 filter means there are likely to be far fewer bad particles in your home's air.
