Remove the filter from the machine first

Most Dyson vacuums have the filter on top of the main unit or on the side, depending on the model. Look for a release button or latch near the filter — it's usually labeled with a small arrow or icon. Press or twist the button and pull the filter straight out toward you. Don't force it; if it's stuck, check that you're pressing the release mechanism fully.

Once the filter is out, tap it gently over a trash can to dislodge loose dust and debris. You'll see a cloud of dust come out — this is normal and expected. Tap it several times until no more dust falls, holding it by the plastic frame, not the filter material itself.

Key Takeaways

  • Dyson filters need cleaning every month and replacing every 12 months, depending on how often you vacuum and whether you have pets.
  • The filter sits on top or the side of your machine and releases with a button or twist mechanism — check your manual if you can't locate it.
  • Wash the filter under cold running water only; hot water damages the material and voids the warranty.
  • Let the filter dry completely (at least 24 hours) before putting it back in the machine, or the motor can be damaged.
  • A replacement filter costs between $40 and $80 depending on your model and where you buy it.

Wash the filter under cold water only

Hold the filter under a cold tap and rinse it from the inside out, letting water flow through the pleats. Use your fingers to gently rub the filter material while rinsing — don't scrub hard or bend the pleats. Keep rinsing until the water runs clear and you see no more dust coming out.

Do not use hot water, soap, or a washing machine. Hot water shrinks the filter material and breaks down the seal, and soap leaves residue that clogs the filter. Dyson's warranty does not cover filters damaged by hot water or improper cleaning.

Dry the filter completely before reinstalling

After rinsing, gently squeeze out excess water by hand — don't wring or twist the filter. Stand it upright on a clean towel or hang it vertically in a warm, dry place. The filter must dry completely, which usually takes 24 hours or longer depending on humidity and air circulation in your home.

Do not use a hair dryer, oven, or direct heat source to speed up drying. Do not reinstall a damp filter; running the vacuum with a wet filter can damage the motor and void your warranty. If you're in a hurry, wash the filter the night before you plan to vacuum.

Put the clean filter back in and test it

Once the filter is completely dry, slide it back into the machine the same way it came out. You should hear or feel a click when it seats properly. Push or twist the release mechanism back into the locked position — it should be snug and not wobble.

Turn on the vacuum and listen for any unusual sounds. The machine should run normally. If you hear a whistling sound or the suction feels weak, the filter may not be seated correctly; remove it and try again.

When to replace the filter instead of washing it

Washing extends the life of your filter, but it does not last forever. After 12 months of regular use, or sooner if you have pets or a dusty home, the filter material begins to break down and won't rinse clean. At that point, you need to buy a replacement filter.

Signs that replacement is due include weak suction even after washing, a filter that stays discolored after rinsing, or visible tears or holes in the material. Replacement filters are sold by Dyson directly, through major retailers like Amazon and Walmart, and through vacuum repair shops. The cost varies by model but typically ranges from $40 to $80.

How often to clean your filter

If you vacuum once or twice a week in a home without pets, wash the filter once a month. If you have pets, a larger home, or vacuum more frequently, wash it every two weeks. If you notice suction dropping between your scheduled cleaning days, wash the filter early — a clogged filter is the most common reason Dyson vacuums lose power.

Mark your calendar or set a phone reminder so you don't forget. A clean filter keeps your vacuum running at full strength and extends the life of the motor.

Frequently Asked Questions

Can I use hot water to clean the filter faster?

No. Hot water damages the filter material and voids your warranty. Use only cold water, and allow 24 hours for drying. If you're short on time, wash the filter the evening before you plan to vacuum.

What happens if I run the vacuum with a wet filter?

A wet filter can damage the motor and may cause the machine to shut off automatically. Always wait until the filter is completely dry before reinstalling it. If you accidentally run it wet, turn off the machine immediately and let the filter dry fully before using it again.

Do I need to buy a new filter every time I clean it?

No. Washing and reusing the filter is normal and expected. Most filters last about 12 months with regular washing. After that, the material breaks down and won't rinse clean, so you'll need to buy a replacement.

Where do I buy a replacement filter?

Dyson sells filters directly through their website, and they're also available at Amazon, Walmart, Best Buy, and local vacuum repair shops. Make sure you order the correct model for your machine — filter sizes vary. Check your manual or the model number on your vacuum to confirm.
