Particle filter with activated carbon for use in rooms where removal of gaseous pollutants, such as tobacco smoke or volatile organic compounds (VOCs), is required. Optional Blueair Carbon+ Filter available, for where even heavier gaseous pollutants are an issue. V-shaped filter that closes like a book prevents exposure to pollutants when changing the filter. Our fiber media is free of chemicals and binders and ultrasonically bonded to prevent new particles from being added to your environment.
