The Airpura HEPA-Barrier post filter traps carbon dust and particles. Filter should be changed at the same time as the carbon filter. Recommended replacement for carbon filter is as needed in heavy applications and at least every 2 years in normal use (change at least once every 3 months in public areas, private home use change interval will be less frequent). Keep your frame when you replace HEPA-Barrier as new frame not included.
