Item Description:

Provides first-pass filtration efficiency

The adddition 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.

With the standard pre-filter, DOP Stage 2 pre-filter and the HEPA primary filter installed, the HEPA 500 passes laboratory DOP testing conducted per ANSI standards, achieving an efficiency rating of 99.97% against oily aerosol particles down to 0.3 microns.

Install the DOP filter between the standard pre-filter and the HEPA primary filter. Use the Activated Carbon Filter together with the DOP filter for highly effective odor removal. Simply replace the paper pre-filter with the carbon filter.

DOP stands for "dispersed oil particulate," the name of a standard procedure for testing the effectiveness of HEPA filtration. The DOP test introduces a dense cloud of extremely fine particulates into the filter under controlled conditions.
