Wash your Dyson filter every month, or more often if you have pets or allergies

A clogged Dyson filter loses suction and forces the motor to work harder, which shortens the vacuum's life. The filter is washable—not replaceable—so cleaning it regularly is how you keep the machine running. Most Dyson models let you rinse the filter under tap water, tap out loose dust, and let it air-dry completely before putting it back.

The exact steps depend on which Dyson model you own, but the principle is the same across all of them: remove the filter, tap out the big dust, rinse gently with water, and dry it fully before reinstalling. A wet filter put back into the vacuum will damage the motor.

Key Takeaways

  • Turn off and unplug your Dyson before you remove the filter, and wait at least 30 minutes after use so the motor cools down.
  • Tap the filter firmly over a trash can to dislodge loose dust, then rinse it under cool running water—never use hot water or a pressure washer.
  • Let the filter air-dry completely in a warm, dry place for at least 24 hours before putting it back in the vacuum.
  • If your filter is visibly torn, has a hole, or does not regain suction after cleaning, it needs to be replaced, not washed.

Where the filter is located on your Dyson

The filter location varies by model. On upright Dyson vacuums (V7, V8, V10, V11, V15), the filter is usually in the dustbin area or mounted on the side of the motor head. On cordless stick models, you may need to detach the main body from the wand to access it. On Dyson uprights with a traditional bin, the filter is often at the top of the bin or clipped to the inside of the motor housing.

Check your model's manual or the Dyson website for your specific machine—the manual will show you exactly where to look and how to release it. Most filters twist or slide out rather than requiring tools.

Step-by-step washing process

Step 1: Power down and cool the vacuum. Unplug the machine from the wall outlet. If you have just used it, wait at least 30 minutes for the motor to cool. A hot motor can be damaged by water.

Step 2: Remove the filter. Open the dustbin or access panel and locate the filter. Twist it counterclockwise or slide it out, depending on your model. Some filters are held by a clip or button—press or release it first. Once loose, pull the filter straight out.

Step 3: Tap out loose dust. Hold the filter over a trash can and tap it firmly on the sides and bottom. You should see a cloud of dust come out. Tap it from different angles to dislodge as much as possible. Do not hit it hard enough to damage the pleats (the ridged folds in the filter material).

Step 4: Rinse under cool water. Hold the filter under a running tap with cool water. Let the water flow through the filter from the clean side (the outside) toward the dirty side (the inside). Do not use hot water, and never use a pressure washer or hose—the force can tear the filter material. Rinse until the water runs clear or nearly clear.

Step 5: Shake out excess water. After rinsing, gently shake the filter over the sink to remove standing water. Do not wring it or squeeze it hard.

Step 6: Air-dry completely. Stand the filter upright in a warm, dry place—a windowsill, shelf, or bathroom with good air flow works well. Do not use a hair dryer, oven, or direct heat. The filter must be completely dry before you put it back in the vacuum. This usually takes 24 hours or longer, depending on humidity. If you put a damp filter back in, it can damage the motor and void your warranty.

Step 7: Reinstall the filter. Once the filter is bone-dry, slide or twist it back into place until it clicks or seats firmly. Make sure it is fully seated—a loose filter will not seal properly and suction will suffer.

What to do if the filter is damaged

If you see tears, holes, or permanent discoloration in the filter material after washing, or if suction does not return after the filter dries, the filter has reached the end of its life and needs to be replaced. Dyson sells replacement filters for each model, and they are not expensive—usually between $30 and $60 depending on the model.

A damaged filter cannot be repaired by washing. Continuing to use a torn filter will allow dust and debris to bypass the filter and damage the motor, which is a much costlier repair. If your filter is still under warranty, check whether Dyson will replace it for free—some models come with a warranty that covers filter defects.

How often to wash the filter

Wash your filter at least once a month if you use the vacuum regularly. If you have pets, allergies, or a lot of carpet, wash it every two weeks. If you notice suction dropping between your regular cleaning schedule, wash it sooner—a clogged filter is the most common reason for loss of suction.

Some Dyson models have a filter-cleaning alert that lights up on the machine when the filter needs attention. If your model has this feature, follow the alert rather than a calendar schedule. The alert is based on how much the vacuum has been used, not just time elapsed.

Common mistakes to avoid

Do not use hot water. Hot water can warp or damage the filter material and reduce its effectiveness. Stick to cool tap water.

Do not use soap or detergent. Water alone is enough to clean the filter. Soap residue can clog the pores and reduce suction.

Do not use a pressure washer, garden hose on high setting, or any high-force water stream. The force will tear the pleats and create holes in the filter.

Do not reinstall a wet or damp filter. This is the most common cause of motor damage. Wait the full 24 hours for complete drying, even if the filter feels mostly dry to the touch.

Do not wash the motor head or other parts of the vacuum with water unless your manual specifically says it is safe. Only the filter is designed to be washed.

Frequently Asked Questions

Can I use a hair dryer to speed up drying?

No. Heat can damage the filter material and change its shape, which reduces suction. Air-drying at room temperature is the only safe method. Plan ahead so you have time to let it dry fully before you need to vacuum again.

What if my filter still smells bad after washing?

A lingering smell usually means the filter did not dry completely or bacteria grew in it while damp. Make sure it is fully dry before reinstalling. If the smell persists after the next wash and dry cycle, the filter may have reached the end of its life and should be replaced.

Do I need to replace the filter if I wash it regularly?

Not necessarily. A well-maintained washable filter can last one to two years or longer with regular cleaning. You only need to replace it if it tears, develops holes, or stops regaining suction after washing and drying.

Can I wash the filter while it is still slightly damp from the last use?

Yes. If the filter has been drying and is no longer dripping wet, you can rinse it again. Just make sure it dries completely afterward before reinstalling.

What if water comes out brown or very dirty after rinsing?

That is normal. Keep rinsing until the water runs clear or nearly clear. It may take several rinses if the filter has not been cleaned in a while. The brown water is dust and debris washing out of the filter material.
