The activated carbon filter now equips the HEPA 500 to capture a wide variety of volatile organic compounds (VOCs), including soot and smoke, food odors, fumes from paint and paint thinners, sewer odors, and many other compounds. With 2.2 pounds of activated carbon, these filters add another layer of filtration to the HEPA air scrubber by adsorbing pollutants that can often pass through a traditional HEPA filter.
No modification of the DefendAir is required – users simply place the new carbon filter inside the cabinet in front of HEPA filter, and then re-secure the cover. Capacity of the carbon filter will vary widely depending on conditions, but it should be replaced when a decline of effectiveness is noted.
Sold in packs of four individually-wrapped filters.
