How To Clean Shop Vac Filter

Regularly cleaning the shop vac filter is important because it helps the machine work more efficiently. When you use your shop vac to clean up a surface or room, the filter absorbs dirt, dust, and particles. This causes the machine to become less efficient. Cleaning the filter regularly prevents this problem.

The Needed Materials And Tools

A trash bin or large container to hold the dirt. You can use a plastic bag as well. Two removable caps will fit over the ends of the filter. Use wood screws to secure them together. Giant nails or rods with heads for holding the filter and caps during the cleaning process are needed.

Don’t forget to use a pair of safety goggles and a mask, if you have one around.

The ShopVac Filter Cleaning Process

You should never wash your filter with water. This may damage the filter.

A heap filter is a type of air purifier that uses a fan to blow air over a filter medium. These filters are usually made of paper, plastic, or glass fiber. They are designed to remove dust particles and other contaminants from indoor air.

Before You Begin

Shop vacs suck up dirt and debris, but they also release them back out into the air. To clean the shop vac, you need to remove the cover off the vacuum and then use an old toothbrush or rag to get inside the vacuum.

Then, turn the machine on and let it run until the brush gets dirty. After this, rinse the brush and put it away. Finally, take the shop vac apart and wash everything thoroughly. Wear a mask when doing this because dust and other particles may be released into the air.

Knock The Dust Loose

A shop vac cleaner should be used to clean out filters. You need to remove the filter by holding it in one hand and tapping it against a solid surface. Then you place your arm into a garbage bag and close it up. Tap the filter again to get rid of any dust. Wait a few minutes until the dust settles. Finally, release the garbage bag.

Dig The Dried Dirt Loose

Wet dry vacuum filters need to be cleaned regularly. A wet/dry vacuum cleaner uses a filter system to trap particles in the air. The filter should be changed periodically, as it collects dust and other debris.

To clean the filter, use a soft brush or cloth to gently scrape off any dirt or debris. Do not use metal tools, such as knives or screwdrivers, to clean the filter. This could damage the filter and cause the machine to stop working properly.

Use Compressed Air To Remove The Embedded Dust

With the bulk of dust, hair, dirt, and other particles removed, it’s time to remove the embedded particle. Any time you’re working with compressed air, it’s a good idea to don a pair of safety glasses to prevent flying chunks from entering your eye.

Lower the compressor pressure down to around 40 psi, and use an air chocker to blow the embedded particles free. Spray the filter from outside, and then spray it again from inside, being careful not to tear the paper pleats or deformed permanently with too much pressure

Wash The Filter In A Bucket Of Warm Soapy Water

To remove the remaining particles, use dishwashing liquid to clean the shop vac filter. Soak the filter for 10 minutes, then plunge it up and down several times. Rinse the filter with a garden hoe after soaking.

Let The Filter Dry

Photo filters need to be dried before they’re used again. Putting a wet filter into a shop vac and blowing it out will cause the dirt to block the filter. Put the filter back in the sun or in an oven to speed up the drying process.

Over time, the pleats of the vacuum cleaner bag will deform and the paper inside will get thinner. This will require a shop vac filter replacement. Keeping a shop vac parts list handy will help you restore the suction power of your vacuum cleaner. You won’t be guilty of shop vac negligence anymore, allowing your machine to clean up messes for many more jobs to come.

Frequently Asked Questions

How Often Should You Change A Shop Vac Filter?

How To Clean Other Types Of Shop Vac Filters?

Shop vacs come in many shapes and sizes. Some are designed to clean carpets while others are meant for cleaning floors. All shop vacs have a filter attached to them.

Rinse the filter by turning on the power switch and letting the water run until the water runs clear. Dry the filter by placing it on a flat surface or towel. Do not use soap when washing your filter because it will damage the foam material.

Reusable dry filters: The steps to cleaning this type of filter is the same as washing it under running water. Ensure that the filter was dry prior to attaching it.

HEPA Filter: Cleaning a HEPA filter is similar to washing it under running water, however, one difference is you can also rinse the outer part with water. Make sure that it completely drips off before putting it back into the vacuum.

Merchants suggest using filter flossers to make the rinsed part more efficient, but they cost extra money, so it’s up to you if you wish to incur that extra expense or not.


Always clean your shop vac after you use it. You should always use the right tool for the job. Use a vacuum cleaner with a HEPA filter to protect your lungs. Don’t use a scrigit scraper when removing debris. Do this carefully to avoid damaging the filter.
