We’ve re-engineered the Big + Quiet to deliver three key features to purify large spaces.¹ Long range projection creates the circulation power to draw even-distant pollutants back to the purifier. Our integrated sensor system detects and reports pollutants from around the room. Finally, three phases of purification sit within the machine, full sealed to HEPA H13 grade.⁹ Capturing gases², odors, ultrafine particles and destroying formaldehyde.⁺ Purified air is then projected back into the room and the cycle repeats.
