Clean your Shark filter by tapping out loose dust, then rinsing it under running water

Most Shark vacuums have a foam or pleated filter that traps fine dust and debris. Over time, the filter clogs and your vacuum loses suction. Cleaning it takes about five minutes and requires only water and a soft brush—no tools or special cleaners needed. You should clean the filter every month if you vacuum weekly, or every two weeks if you have pets or carpet.

The exact steps depend on your Shark model, but the process is nearly identical across the brand. This guide covers the most common filters found in upright and lift-away Shark vacuums. Check your manual if your model has a HEPA filter (a dense, accordion-style filter) or a cartridge filter, as those need slightly different care.

Key Takeaways

  • Turn off and unplug your vacuum before removing the filter to avoid accidental startup.
  • Tap the filter firmly over a trash can to dislodge loose dust before you rinse it.
  • Rinse the filter under cool running water, holding it with the pleats pointing downward so water flows through them.
  • Let the filter air-dry completely—at least two hours, or overnight—before putting it back in the vacuum.
  • If water alone does not restore suction after the filter dries, the filter may need replacement rather than cleaning.

Locate and remove the filter from your Shark

On upright Shark models, the filter is usually mounted on top of the dust cup or inside the main body near the motor. On lift-away models, it is often in the handheld unit. Unplug the vacuum first, then look for a release button or clip holding the filter in place. Press or slide the button, and the filter will pop out or pull free.

Some filters sit in a cage or holder. If yours does, gently twist or slide the cage counterclockwise to unlock it, then lift the filter straight up and out. Do not force it—if it feels stuck, check for a second clip or button you may have missed. Once the filter is out, set it aside over a trash can or sink.

Tap out loose dust over the trash can

Hold the filter vertically with the pleated side facing down. Tap the bottom and sides firmly against the inside of a trash can or over a sink. You should see a cloud of dust come out. Keep tapping for 10 to 15 seconds—this removes the bulk of trapped dust and makes rinsing much more effective.

If the filter is very clogged, tap it at different angles to dislodge dust from all sides. Do not hit it so hard that you dent the pleats or crack the foam. A firm, steady tap works better than a hard whack.

Rinse the filter under cool running water

Hold the filter under a faucet with cool or lukewarm water. Point the water so it flows through the pleats from the inside out—this pushes dust out rather than deeper into the filter. Rotate the filter slowly as you rinse, making sure water reaches all sides. Rinse for 20 to 30 seconds, or until the water runs clear.

Do not use hot water, as it can damage foam filters. Do not use a hose on high pressure—the force can tear the pleats. If the filter is very dirty, you can soak it in a sink of cool water for 10 minutes before rinsing, which helps loosen stubborn dust.

Gently clean stubborn spots with a soft brush

If rinsing alone does not remove all the dust, use a soft brush—a soft toothbrush or a dedicated filter brush works well. Brush gently along the pleats in the direction they run, not across them. Brush from the inside out to push dust away from the filter material. Rinse again after brushing.

Never use a stiff brush or scrub hard, as this can damage the pleats or tear the foam. If a spot still will not come clean after gentle brushing and rinsing, the filter may be permanently clogged and need replacement.

Let the filter dry completely before reinstalling

Shake off excess water gently, then stand the filter upright on a clean towel or paper towel to air-dry. Do not use a hair dryer or place it near a heat source—air-drying only. The filter needs at least two hours to dry, but overnight is safer. You can tell it is fully dry when it feels light and no moisture comes out when you squeeze it gently.

Never put a wet or damp filter back into your vacuum. Running the vacuum with a wet filter can damage the motor and create mold inside the machine. If you are in a hurry, clean the filter the night before you plan to vacuum.

Reinstall the filter and test your vacuum

Once the filter is completely dry, slide it back into its cage or holder, then push the cage back into the vacuum until you hear or feel it click into place. If your filter sits directly in the body, align it and push straight down until it locks. Check that it is seated firmly—a loose filter will not seal properly and suction will suffer.

Plug in the vacuum and turn it on for a few seconds to test suction. You should notice a clear improvement over the clogged filter. If suction is still weak after the filter has dried, the filter may be worn out and need replacement. Shark filters typically last 6 to 12 months with regular cleaning.

Frequently Asked Questions

Can I wash the filter with soap or cleaning solution?

Plain water is best and usually all you need. If you want to use soap, use only a tiny amount of mild dish soap mixed into cool water, then rinse very thoroughly until no soap residue remains. Soap left in the filter can reduce suction and create odors. Most Shark owners find water alone works fine.

What if my filter still looks dirty after rinsing?

Some discoloration is normal and does not mean the filter is not clean. If the filter is still clogged after rinsing and brushing, it may have reached the end of its life. Shark filters typically last 6 to 12 months. Check the model number on your vacuum and order a replacement filter from the manufacturer or a retailer.

How often should I clean the filter?

Clean the filter every month if you vacuum once a week on carpet or hard floors. If you have pets, vacuum more often, or have a lot of dust, clean it every two weeks. If you notice suction dropping between cleanings, that is a sign to clean it sooner.

Can I use a vacuum to suck dust out of the filter instead of rinsing it?

You can tap the filter and use a handheld vacuum to catch loose dust, but rinsing is more effective at removing fine particles trapped deep in the pleats. Tapping plus rinsing together gives the best results. A vacuum alone will not clean the filter thoroughly enough.

What happens if I put a damp filter back in the vacuum?

A damp filter can damage the motor, create mold inside the machine, and reduce suction. Always let the filter dry completely—at least two hours, preferably overnight—before reinstalling it. If you are in a hurry, clean the filter the evening before you plan to vacuum.
