Clean your Dyson filter every month, or whenever the red light appears on the machine

A clogged filter is the most common reason a Dyson loses suction. The filter traps dust and allergens, but when it fills up, air can't flow through the motor properly. Dyson filters don't need replacement as often as filters in other vacuums—you clean and reuse the same one. Most Dyson models have a filter you can access in under a minute without tools.

The exact location and shape of your filter depends on your model. Upright models usually have the filter on top of the canister or on the side. Cordless stick models have it near the motor head. Handheld models have a smaller filter tucked into the body. Check your model number on the back or bottom of the machine if you're unsure which type you have.

Key Takeaways

  • Most Dyson filters should be cleaned once a month or when the red light appears, without removing the filter from the machine.
  • Tap the filter firmly over a trash can to dislodge dust, then rinse it under cold running water until the water runs clear.
  • Let the filter dry completely—at least 24 hours in a warm room—before putting it back in the vacuum.
  • Never use hot water, a washing machine, or a dryer on your filter, as heat damages the filter material permanently.
  • If your filter is torn, stained permanently, or doesn't regain suction after cleaning, it needs to be replaced with a genuine Dyson filter.

How to access and remove your filter

For upright models, look for a button or latch on the side or top of the canister. Press it and twist the filter counterclockwise, or pull straight out depending on your model. The filter will come free in your hand. For cordless stick models, locate the filter near the motor head (usually marked with a filter icon) and unscrew it by turning counterclockwise. For handheld models, the filter is typically accessed by opening a panel on the side or bottom.

If you're not sure which direction to turn, check the arrow printed on the filter itself—it shows which way to unscrew. Don't force it. If it feels stuck, tap the canister gently on the side to loosen any compacted dust, then try again. Once removed, hold the filter over a trash can when ready, as loose dust will fall out.

Tapping out loose dust without water

Before you rinse, tap the filter firmly over a trash can or outside. Hold it by the plastic frame, not the pleated filter material itself. Tap the side of the filter against the edge of the trash can several times. You'll see a cloud of dust come out—this is normal and means the method is working. Keep tapping until no more dust falls out when you hit it.

This step removes the bulk of the dust and makes the rinsing step faster and more effective. Some people skip it and go straight to water, but you'll get better results if you tap first. The dust that comes out this way is dry and won't clog your sink drain.

Rinsing the filter under running water

Hold the filter under cold running water from a tap. Let the water flow through the pleats from the inside out—the direction the air normally flows through the vacuum. Rotate the filter slowly under the water so all sides get rinsed. You should see dirty water running off at first. Keep rinsing until the water runs clear, which usually takes 30 seconds to two minutes depending on how much dust was trapped.

Never use hot water, as heat can damage the filter material and reduce its ability to trap dust. Don't use a brush or scrub the filter, as this can tear the pleats. If the filter has stubborn stains or discoloration that won't rinse away, that's normal—stains don't affect how the filter works. What matters is that water flows through freely.

Drying your filter completely before reinstalling

This step is critical and often rushed. A wet filter will damage your Dyson's motor if you turn it on. After rinsing, gently shake the filter over the sink to remove excess water. Stand it upright (pleats pointing up) on a clean towel or paper towel in a warm, dry room. A windowsill, shelf, or counter away from direct sunlight works well.

Leave the filter to air-dry for at least 24 hours. In humid climates or winter, it may take longer. You can speed this up slightly by placing it in a room with a fan or dehumidifier, but don't use a hair dryer, oven, or any direct heat source—heat will warp the filter. Once it feels completely dry to the touch and has no moisture inside the pleats, it's ready to reinstall.

Putting the filter back and checking the seal

Align the filter with the slot or threaded opening where it came from. For screw-in filters, turn clockwise until snug—don't over-tighten. For push-fit filters, push straight in until you hear a click or feel it seat fully. Check that the filter is seated evenly all the way around. A filter that's not fully seated will leak unfiltered air and reduce suction.

Once reinstalled, empty the canister if you haven't already, then run the vacuum briefly to confirm suction has returned. The red light should turn off if it was on. If suction is still weak after cleaning and drying, the filter may be damaged or worn out and need replacement.

When to replace your filter instead of cleaning it

Dyson filters last roughly 12 months with regular monthly cleaning, though this varies based on how often you vacuum and what you're picking up. If your filter has visible tears, holes, or permanent damage to the pleats, it can't be repaired and needs replacement. You can buy genuine Dyson filters from the manufacturer's website, Amazon, or retailers that sell Dyson products.

If the filter is clean and dry but your vacuum still has weak suction, the problem may not be the filter. Check that the canister is empty, the brush bar isn't clogged with hair, and the air pathways aren't blocked. If suction returns to normal after cleaning the filter, you're done. If it doesn't, contact Dyson support or consult your manual for other potential causes.

Frequently Asked Questions

Can I use a vacuum to clean the dust out of my Dyson filter?

No. Using another vacuum on your Dyson filter can damage the pleats and push dust deeper into the material. Tapping over a trash can and rinsing under water are the correct methods. If you're worried about dust in your home, do the tapping step outside or over a trash can with a lid.

What if my filter is still wet after 24 hours?

Move it to a warmer, drier location with better air circulation. A room with a fan or dehumidifier will help. In very humid climates, it may take 36 to 48 hours. Never use heat directly on the filter. If it's been drying for more than two days and still feels damp inside the pleats, there may be a problem with the filter itself, and replacement may be necessary.

Do I need to clean the filter if the red light hasn't come on yet?

Monthly cleaning is recommended even if the light hasn't appeared, especially if you vacuum frequently or have pets. The red light indicates the filter is very clogged, but cleaning monthly keeps suction strong and extends the filter's life. If you vacuum only occasionally, you can wait for the light, but monthly is the safer schedule.

Can I wash my Dyson filter in the washing machine?

No. The washing machine uses hot water and agitation, both of which damage the filter material permanently. Hand-rinse under cold running water only. The same applies to dishwashers and dryers—never use them on your filter.

What's the difference between cleaning and replacing the filter?

Cleaning removes dust and restores suction without removing the filter from service. Replacement means buying a new filter and discarding the old one. Most Dyson filters are cleaned many times over their lifetime. You only replace when the filter is damaged, torn, or no longer regains suction after cleaning.
