BOFA Filter for AD Access Fume Extractor - Pre-Filter

A replacement for one of the two filters in the AD Access Fume Extractor. The pre-filter is designed as a barrier to capture the larger dust and particulates that would otherwise be caught in the HEPA filter. By keeping the pre-filter clean, the HEPA filter will have a vastly greater lifespan.

This is an F8 rated filter, with 95% efficiency at 0.9 microns. It is recommended you replace the filter every 12 to 18 months.
