CLEANING A WET DRY VACUUM FILTERS – Dry Filters:
1. Unplug Shop Vacuum Power Cord
Always unplug the power cord before cleaning or removing the filter. This step prevents accidents.
2. Work in a well-Ventilated Area
It is recommended to clean the Filter in an open, ventilated area. Because cleaning will put dust in the air it SHOULD not be done indoors. • Note: If you have allergies or health concerns it may be prudent to simply replace the filter.
3. Removing Debris
- Method 1– Tapping or shaking the vacuum. Light cleaning of some dry debris from the filter can be accomplished without removing the filter from the vac. Simply slap your hand or soft brush on top of the handle and allow debris to drop down into the dust drum
- Remove Filter- Other methods require the filter to be removed. This process varies and is covered more thoroughly our article on “How To Change/Replace Your Wet/Dry Vac Filter” available here and on the WORKSHOPvacs.com website as a PDF. For most units the powerhead is removed to access the drum and shop vacuum filter.
- Method 2– Remove Vacuum Filter & Tap. For slightly tougher jobs. Gently tap the filter against the inside wall of your dust drum or a trash can and the debris will loosen and fall. Make sure you are in a ventilated area. We suggest outside so that dust is not pushed throughout the house, shop, or garage.
- Method 3– Bag Vacuum Filter & Tap. This is similar to Method 2, but place the filter in a plastic of garbage bag to collect and contain the debris. This method does collect debris, but because the area is confined it tends to keep debris near the filter to resettle on the paper material, taking longer to thoroughly clean the filter.
- Method 4– Compressed air. Using compressed air you can blow the debris off of your filter. It is best to blow from the inside of the filter out to remove the debris. Take care that air pressure (PSI) is not strong enough to damage filter.
- Method 5– “Wash” For thorough cleaning, especially when cleaning fine dust, you may clean with water. This method often works best if larger debris is removed using other methods first. Tips for using this method is in the next section for cleaning a wet filter.
