Clean your Dyson filter by tapping out loose dust, rinsing under cold water, and air-drying for at least 24 hours before reinstalling

A clogged Dyson filter reduces suction and makes the motor work harder. Most Dyson models let you clean the filter yourself without tools—it takes about 10 minutes of hands-on time, though the drying period is longer. The filter should be cleaned every month if you use the vacuum regularly, or whenever you notice suction dropping.

The exact steps depend slightly on your Dyson model, but the core process is the same across uprights, cordless stick vacuums, and cylinder models. This guide covers the most common Dyson filters: the pleated fabric filters found in V-series cordless models and upright machines.

Key Takeaways

  • Turn off and unplug your Dyson before removing the filter to avoid accidental motor start.
  • Tap the filter firmly over a trash bin to dislodge loose dust and debris trapped in the pleats.
  • Rinse the filter under cold running water only—hot water damages the fabric and reduces filter life.
  • Let the filter air-dry completely for at least 24 hours before putting it back in the vacuum.
  • Never use a dryer, oven, or heat source to speed drying, as this will permanently damage the filter.

Locate and remove the filter from your Dyson model

The filter location varies by model. On cordless V-series vacuums (V7, V8, V10, V11, V15), the filter is usually on top of the dust bin or attached to the motor head. On upright Dyson models, it is typically on the side or back of the machine. Check your model's manual if you are unsure—Dyson's website has PDFs for every model number.

To remove the filter, first unplug the vacuum or power it off completely. On cordless models, press the release button or twist the filter counterclockwise until it comes free. On uprights, you may need to unlatch a clip or unscrew a cover. Once removed, hold the filter over a trash bin so loose dust falls directly into it rather than onto your floor.

Tap out loose dust and debris

Hold the filter vertically over the open trash bin and tap the sides and bottom firmly with your hand or a soft brush. You should see a cloud of dust come out—this is normal. Tap for 10 to 15 seconds, rotating the filter so you hit all sides. This step removes the bulk of trapped dust and makes the water rinse much more effective.

Do not bang the filter hard against the bin edge or hit it with a hard object, as this can tear the pleated fabric or crack the plastic frame. A firm tap with your palm is enough. If dust is still visibly caked on after tapping, you may have waited too long between cleanings, but the rinse step will still help.

Rinse the filter under cold running water

Hold the filter under a cold tap and let water run over all sides for 10 to 15 seconds. You can gently rub the pleats with your fingers to help water flow through, but do not squeeze or wring the filter. The goal is to flush out fine dust particles trapped deep in the fabric. You should see dirty water run off at first, then clearer water as the filter cleans.

Use cold water only. Hot water damages the electrostatic charge in the filter material, which reduces its ability to trap dust. Never soak the filter in a bucket or use a pressure washer. If the filter still looks very dirty after a cold rinse, repeat the process—a second rinse often removes more trapped dust.

Shake off excess water and prepare to dry

After rinsing, hold the filter upright and gently shake it to remove excess water. You can tap it lightly against the sink or a towel. Do not wring or squeeze it. Place the filter on a clean, dry surface—a kitchen towel, paper towels, or a clean cloth work well. Stand it upright so air can flow around all sides.

Some people place the filter in a warm (not hot) room or near a fan to speed drying, but this is optional. The key is air circulation and time, not heat. Avoid placing it in direct sunlight for extended periods, as UV light can degrade the plastic frame.

Air-dry for at least 24 hours before reinstalling

Leave the filter to dry completely before putting it back in your Dyson. This usually takes 24 hours in a normal room, longer in humid climates. You can check if it is dry by feeling the fabric—it should be completely dry to the touch, not damp or cool. If you reinstall a damp filter, it can reduce suction and may cause mold growth inside the motor housing.

Once the filter is fully dry, reattach it to your Dyson by reversing the removal steps. On cordless models, align the filter and twist clockwise until it clicks. On uprights, slide it back into place and find any latches or covers. Your vacuum is now ready to use at full suction again.

When to replace the filter instead of cleaning

Cleaning extends filter life, but filters do not last forever. If your Dyson still has weak suction after cleaning and drying a filter, or if the fabric is visibly torn or discolored, the filter has reached the end of its life. Most Dyson filters last 6 to 12 months with regular cleaning, depending on how often you vacuum and what you pick up.

Replacement filters are sold on Dyson's website and through retailers like Amazon and Walmart. They cost between $20 and $60 depending on the model. Buying a spare filter and cleaning one while the other dries means you never have to wait 24 hours between vacuuming—you can swap them out and keep cleaning right away.

Frequently Asked Questions

Can I use hot water to clean the filter faster?

No. Hot water damages the electrostatic material in the filter, which traps fine dust particles. Once that charge is gone, the filter cannot be restored and must be replaced. Always use cold water, even if it takes longer to rinse.

What if the filter still smells bad after cleaning and drying?

Odor usually means mold or mildew is growing in the fabric. This happens if the filter was reinstalled before it was completely dry, or if it was stored in a damp place. Let it dry in a warm, dry room with good air flow for another 24 hours. If the smell persists, the filter should be replaced.

Do I need to clean the filter if I empty the dust bin regularly?

Yes. The dust bin and the filter trap different sizes of particles. The bin catches large debris, but fine dust still builds up in the filter pleats. Even with a nearly empty bin, the filter can be clogged. Clean it monthly or whenever suction drops.

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

Tapping and rinsing are more effective than vacuuming. A vacuum removes loose dust but leaves fine particles embedded in the pleats. Cold water rinses flush out trapped dust that a vacuum cannot reach. Stick with tapping and rinsing for the best results.

How do I know if my Dyson filter is the type that can be cleaned?

Most modern Dyson filters are washable. Check your model's manual or the filter itself—washable filters usually say "washable" or "rinse-friendly" on the packaging or frame. Some older or specialty filters are not washable and must be replaced. When in doubt, contact Dyson support with your model number.
