This second-stage particulate filter, manufactured for use with Abatement Technologies models PAS500/PAS600/PAS1000/PAS1200, works best when changed as recommended, every 3-7 days.

This filter offers superior construction and is the standard filter for your original Phoenix 200 dehumidifier and your Phoenix Mini-Guardian Air Scrubber.

The addition of the DOP filter makes the DefendAir HEPA 500 a high efficiency three-stage air filtration unit, ready for any sensitive job requiring first-pass HEPA filtration.
