How it Works

The T100 circulates air in smaller spaces up to 125 square feet. Air passes through three layers of advanced HEPA style materia, where allergens and particles are captured and removed from the air. An ozone-safe Ionizer also complements the HEPA style filter by charging particles in the air, causing them to stick together and become more easily captured. Once air moves through the filter, purified air is then circulated back into the room.

When To Use It

After conducting air quality studies, our Air Purifiers America experts have found the air quality in a room can returned to pre-cleaned levels only two hours after turning off an air purifier. Based on these findings, we recommend you run your air purifier 24/7 to maintain the cleanest air possible. If you run your air purifier at the recommended levels, you air purifier will require a new filter every 6-8 months. .
