Allerair AirMed 3 Supreme Exec Carbon Filter
15 lbs of activated carbon filter with granular carbon for better filtration of chemicals and odors. Most compact air purifiers only have a sprayed-on mesh carbon filter that saturates quickly.
The Carbon Filter Should be changed after approximately 12 months of use in an average home environment. A noticeable decrease in air quality could also be a sign that it may be time to replace this filter.
