The Airpura Replacement HepaBarrier Filter is for the C600 Airborne
Chemicals Air Purifier and T600 Tobacco Smoke Air Purifier.
HepaBarrier traps particles and dust after the carbon bed.
HepaBarriers should be changed every 12 months. For the T600 filters
should be changed at the same time as the carbon filter. For private
