NaceCare 900391 Replacement Filter for the CV 570 CombiVac


The CV 570 CombiVac is built around one idea: pick up wet or dry without stopping to swap filters. This cartridge is the part that makes that work, and 900391 is the replacement NaceCare lists for it.

It fits the standard CV 570 head and handles both jobs, so a custodian can vacuum a spill and then the dry grit around it in the same pass.


The Owner's Insights on the CV 570 Filter

Because the CV 570 never has its filter swapped out, this cartridge does more work than the filter on a dry-only canister. After wet jobs, let it dry completely before you put the lid back on and store the machine. A filter left damp in a closed tank is where the musty smell comes from.

Replace it when it's torn, clogged with fine paste from drywall or concrete dust, or when suction stays weak with an empty tank. A spare on the shelf means the machine never sits waiting on a part.


Which Vacuums Take Filter 900391?

The WV 900 and WV 1800 wet vacs use the Permatex filters instead: 604116 and 604113.
