DualProtection Filters for the Blueair models 405 and 480i air cleaners contain activated carbon for use in rooms where there are gaseous pollutants such as tobacco smoke, odors, or volatile organic compounds (VOCs). They are an optional upgrade for the standard Particle Filter that comes in the Blueair 405, or a replacement of the DualProtection filter that came as a standard feature in the Blueair 480i. In addition to the allergen particle-trapping abilities of standard Blueair Particle filters, these DualProtection filters contain a layer of coconut carbon to trap gaseous substances and annoying odors. Replace every 6 months. Note that no air filter can eliminate all hazardous contaminants of second-hand smoke.
