How We Do It
Our 5-step HEPA air filtration system purifies your air one layer at a time until you are left with fresh, crisp feeling air.
Step 1
Carbon Prefilter
This filter is the first line of defense against poor indoor air quality. It starts by removing lint and large particles.

Step 2
HEPA Filter
Our HEPA filters remove pollutants down to 0.3 micron in size. Learn more about particle sizes here.
Step 3
Two Germicidal UVC Lamps
The UVC lamps zap and kill bacteria, viruses, mold, fungi & allergens.

Step 4
Photo Catalyric Oxidation (PCO) Filter
This removes volatile organic compounds, or "VOC's." Learn more about VOC's and other harmful pollutants.
