NaceCare 604113 Secondary Permatex Filter for the WV 900 and WV 1800 Wet Vacs


NaceCare lists the 604113 secondary Permatex filter for its 900 and 1800 series wet vacs: the WV 900, the WV 1800DH and the WV 1800P and WVD 1800P pumpers. It's the filter that stays in when you're picking up water, catching debris and spray before air reaches the motor.

Permatex media is washable and stands up to being wet every day, which is exactly what a flood or floor-stripping vac needs.


The Owner's Insights on Wet Vac Filters

After a stripping job, this filter holds slurry and finish. Rinse it in clean water, let it dry, and it's ready for the next shift. Skip the rinse and it hardens, airflow drops and the vac starts to sound strained.

Keep a spare so one can dry while the other works. That's the cheapest insurance a 20-gallon wet vac can have.


Which Wet Vacs Take Filter 604113?

For dry pickup on the WV 900, use the 14-inch primary filter 604116 with an NVM-4BH bag. The CV 570 takes its own cartridge, 900391.
