Source for Rigid Canister style Air Filtration System Pre filters...

[Clarence Martinn]

Got an older Rigid canister style Air Filtration System. I went to pull out the black pre filter to clean it, and the pre filter fell apart in tiny pieces in my hand . Call the Orange Box store where I bought it YEARS AGO !!! Apparently, Rigid no longer makes those Air Filtration Systems. At least the hanging canister style. Does anyone know where you can buy those pre filters ??? The machine runs fine , just the filter needs to be replaced.

Not an exact answer, but on a recent chair seat recovering, I had some polyester batting left over. On my CPAP (circa 2004) machine outer filter is gone, so I used a scrap of the polyester batting to replace it.

I think that might be a hard one to find . Might have to make it .

believe it's a re-badged Shop-Vac filter. Might check with them as a source.
