Unparalleled Filtration Efficiency

The design creates a filter with a large surface area, enabling the box fan to move high flow rates of air across the material. The engineer team tested in modeled conditions with an outdoor fine particle concentration of 165 µg/m3 in rooms of at least 1,200 cubic feet. Results displayed PM2.5 removal effectiveness of greater than 80% within just 30 minutes of operation.
