If you primarily use your vac to pick up wet messes or are using reusable dry filters, part of your filter is a foam sleeve. The good news is, you can clean this too.
NOTE:
Our reusable dry filters can be rinsed off and reused over and over again, but it’s very important that they are completely dry when you put them back in your wet dry vac.
Rinse them with water to remove debris and then leave them out to dry before you replace them. Do not machine wash or dry.
