Where the Dyson filter is and why it clogs

The filter on a Dyson vacuum is usually located on top of the main unit or on the side, depending on your model. It looks like a cylindrical cartridge with pleated folds running lengthwise. The filter traps dust and allergens as air passes through it on the way to the motor, so it gets clogged over time — sometimes faster if you have pets or a dusty home.

When the filter clogs, your vacuum loses suction because air cannot move freely through the machine. You might notice the motor sounds strained or the bin fills up faster than it used to. Cleaning the filter regularly — roughly every month, or more often if you vacuum daily — keeps your Dyson working at full power and extends the life of the motor.

Key Takeaways

  • The filter is usually on top of the unit or the side; check your model's manual to find the exact location and removal method.
  • Tap the filter gently over a trash can to dislodge loose dust before rinsing it with water.
  • Never use a washing machine, dishwasher, or hot water on the filter, as heat and agitation damage the pleats.
  • Let the filter dry completely — at least 24 hours in a warm room — before putting it back in the vacuum.
  • If the filter is torn, stained permanently, or does not restore suction after cleaning, it needs to be replaced.

How to remove the filter safely

Turn off and unplug your Dyson before you touch the filter. Locate the filter housing — on most upright models it is on top of the main body, while on cordless stick models it may be on the side or back. Look for a release button, latch, or twist-lock mechanism near the filter.

Press or twist according to your model's design, then pull the filter straight out. Do not yank it at an angle, as the pleats can bend or tear. Set it aside on a clean surface. If you are unsure how your specific model comes apart, the manual that came with your vacuum or the Dyson website has a diagram for your serial number.

Tapping and rinsing the filter

Hold the filter over a trash can and tap it gently on the bottom and sides with your palm or a soft brush. You will see a cloud of dust come loose. Keep tapping until no more dust falls — this removes the bulk of the buildup without water. Do not bang it hard or tap the pleats directly, as you can crack them.

Once you have tapped out the loose dust, rinse the filter under cool running water. Hold it pleated-side down so water flows between the folds. Gently rub the outside with your fingers to help dislodge stubborn dust. You can also hold it pleated-side up and let water run down the inside. Never use hot water, a brush, or a pressure washer — all of these damage the filter material.

Drying the filter completely

Shake off excess water gently and stand the filter upright on a clean, dry towel in a warm room. A bathroom with the door closed or a room near a window works well. The filter must dry completely before you put it back in the vacuum — moisture left inside can damage the motor or create mold.

Drying usually takes 24 hours or longer depending on humidity and air circulation. Do not use a hair dryer, oven, or direct heat source, as high temperatures warp the plastic housing and shrink the filter material. If you are in a hurry, stand the filter in front of a fan in a warm room to speed up the process, but still allow at least 12 hours before reinstalling.

Putting the filter back and testing suction

Once the filter is completely dry, slide it back into the housing and find it with the release button, latch, or twist-lock — whichever your model uses. Make sure it sits flush and clicks or locks into place. Plug in the vacuum and turn it on. You should notice an when ready improvement in suction if the filter was the cause of the loss.

Run the vacuum over a small area to confirm it is working normally. If suction is still weak after cleaning, the filter may be damaged or the clog may be elsewhere in the machine — check the hose, brush head, and bin for blockages.

When to replace the filter instead of cleaning it

If the filter has visible tears, holes, or permanent stains that do not rinse away, it cannot trap dust properly and needs to be replaced. Dyson sells replacement filters for each model, and they are available through the Dyson website, Amazon, and most appliance retailers. The part number is printed on the old filter or in your manual.

Even with regular cleaning, filters wear out over time — usually after one to two years of normal use. If you clean the filter monthly and suction still does not return to normal, replacement is the next step. A new filter costs between $30 and $80 depending on your model and usually arrives within a few days.

Keeping your filter cleaner longer

Empty the bin after every use, especially if you have pets or a shedding household. A full bin forces more air through the filter, clogging it faster. If you vacuum fine dust like flour, baking soda, or drywall dust, the filter will clog more quickly — consider using a shop vacuum for those jobs instead.

Some Dyson models have a pre-filter or secondary filter. Check your manual to see if yours does, and clean both filters on the same schedule. Keeping the bin, hose, and brush head clear of blockages also reduces the load on the main filter and helps it last longer.

Frequently Asked Questions

Can I wash the filter in a washing machine or dishwasher?

No. Heat and agitation damage the pleated material and the plastic housing. Hand-rinse under cool running water only, and let it air-dry completely before reinstalling.

How often should I clean the filter?

Once a month is standard for most households. If you vacuum daily, have pets, or live in a dusty area, clean it every two weeks. Check the filter visually — if it looks gray or clogged, clean it sooner.

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

Odor usually means the filter was not fully dry before you put it back, or moisture is trapped inside. Remove it, let it dry for another 24 hours in a warm, well-ventilated space, and try again. If the smell persists, the filter may need to be replaced.

Is there a filter cleaning cycle on my Dyson?

Some newer Dyson models have a filter-cleaning alert that tells you when to clean it. Check your manual or the app for your model. The alert is a reminder, not automatic cleaning — you still have to remove and rinse the filter by hand.

Can I use compressed air to clean the filter?

Compressed air can help dislodge dust, but use it gently and from a distance. Aim it between the pleats, not directly at them. Tapping by hand is usually safer and just as effective for routine cleaning.
