P95 Pre-Filter Retainer over a P100 Filter

thingiverse

Retainer and Grid for adding a P95 pre-filter on top of a P100 filter to extend its life and prevent clogging. In the past, I've quickly ruined several P100 filter cartridges with fine dust or car waxes that cured and the P100 filter became permanently clogged. By adding a P95 pre-filter, your P100 cartridge can be protected, and simply change out the cheap P95 pre-filters when dirty. Generic P95 filters can be found for only about $1 a pair. Thanks, Hope this helps someone out.
