Clean your Dyson filter by tapping it over a bin, then rinsing it under cold water—never use hot water or a washing machine
Your Dyson cordless vacuum's filter traps fine dust and particles that would otherwise escape back into the air. Over time, the filter clogs and your vacuum loses suction. Cleaning it is straightforward: you tap it to dislodge loose dust, rinse it under cold running water, let it dry completely (at least 5 hours, ideally overnight), and put it back. Most Dyson owners need to clean the filter every month or two, depending on how often they vacuum and whether they have pets or allergies.
The exact steps depend slightly on which Dyson model you own, but the principle is the same across all cordless machines. This guide covers the most common models—V15, V11, V10, V8, and V7—and tells you what to avoid so you don't damage the filter.
Key Takeaways
- Remove the filter by twisting or pressing the release button (depending on your model), then tap it firmly over a trash bin to shake out loose dust.
- Rinse the filter under cold running water only; hot water damages the filter material and voids the warranty.
- Never wash the filter in a washing machine, dishwasher, or with soap—water alone is all you need.
- Let the filter dry completely in a warm, dry place for at least 5 hours before reinstalling it; a damp filter will damage the motor.
- If the filter is torn, stained permanently, or no longer cleans properly after drying, it needs to be replaced rather than cleaned.
Locate and remove the filter from your Dyson
On most Dyson cordless models, the filter sits inside the dust bin or on top of the main body. Open the dust bin door or look at the top of the vacuum near where the handle connects. You will see a cylindrical or flat filter, usually white or gray.
To remove it, look for either a twist-release or a push-button release. On V15, V11, and V10 models, the filter typically twists counterclockwise to release. On V8 and V7 models, you usually press a button or lever and pull the filter straight out. Check your user manual if you are unsure—the release method varies by year and region.
Tap the filter to remove loose dust
Once the filter is out, hold it over a trash bin or outside (so dust does not spread through your home). Tap the filter firmly on the sides and bottom of the bin, or tap it gently against your hand. You will see a cloud of dust come out. Keep tapping until no more dust falls—this is the most important step, because loose dust blocks water from reaching the deeper layers of the filter.
Do not hit the filter hard enough to dent or bend it. The goal is to shake the dust loose, not to damage the pleats (the ridged sections that trap particles).
Rinse the filter under cold water only
Hold the filter under a cold running tap. Let water flow through the pleats from the inside out—this pushes trapped dust toward the outside surface. Rotate the filter as you rinse so water reaches all sides. Rinse for 10 to 15 seconds, or until the water runs clear.
Never use hot water. Hot water damages the filter material and can void your warranty. Do not use soap, detergent, or cleaning products. Water alone removes the dust; anything else can leave residue that clogs the filter further or damages the motor when you turn the vacuum on.
If the filter is very dirty or stained, rinsing may not restore it to white. That is normal. As long as water flows through it and it dries properly, it will work. If water does not flow through at all, or if the filter has a tear or hole, it needs to be replaced.
Dry the filter completely before reinstalling
Shake off excess water gently, then stand the filter upright in a warm, dry place. A bathroom, kitchen, or laundry room works well. Do not place it near a heater or in direct sunlight, and do not use a hair dryer or oven—heat can warp the filter.
Wait at least 5 hours, but ideally overnight (8 to 12 hours), before putting the filter back. A damp filter will damage the motor and may cause the vacuum to shut off automatically as a safety measure. You can check if it is dry by touching the inside—it should feel completely dry, not cool or damp.
Reinstall the filter and test the vacuum
Once the filter is dry, reverse the removal process. If you twisted it out, twist it back in clockwise until it clicks or stops. If you pressed a button to remove it, align the filter and push it in until you hear or feel it lock. Make sure it is seated firmly—a loose filter will not seal properly and dust will bypass it.
Turn on the vacuum and listen. It should sound normal. If it sounds strained or shuts off after a few seconds, the filter may still be damp or not seated correctly. Turn it off, remove the filter, and check both.
When to replace the filter instead of cleaning it
Cleaning extends the life of your filter, but it does not last forever. Most Dyson filters last 6 to 12 months with regular cleaning, depending on use. Replace the filter if:
- It has a visible tear, hole, or damage to the pleats.
- Water no longer flows through it after rinsing (it is permanently clogged).
- It is stained dark gray or brown and does not lighten after drying.
- Your vacuum still has weak suction even after the filter is clean and dry.
Replacement filters are available from Dyson's website, Amazon, and other retailers. They cost between $30 and $80 depending on the model. Installing a new filter is the same process as reinstalling a cleaned one.
Frequently Asked Questions
How often should I clean my Dyson filter?
Most owners clean the filter every month or two. If you vacuum daily, have pets, or have allergies, clean it monthly. If you vacuum once a week in a pet-free home, every two months is usually enough. If suction drops noticeably, clean the filter—that is the best signal that it needs it.
Can I use a vacuum to clean the dust out of my filter?
Yes. Use a handheld vacuum or the hose of another vacuum to suck dust out of the filter before rinsing. This removes loose particles faster than tapping alone. Do not use a brush or compressed air, as these can damage the pleats.
What happens if I use hot water on the filter?
Hot water can melt or warp the filter material and damage the adhesive that holds the pleats together. It may also void your warranty. Stick to cold water only.
Can I put the filter back in before it is completely dry?
No. A damp filter will damage the motor and the vacuum may shut off as a safety measure. Always wait until the filter is completely dry, which takes at least 5 hours but is best done overnight.
Do I need to replace the filter if it is still stained after cleaning?
Not necessarily. Staining does not affect performance as long as water still flows through the filter and suction is normal. If the filter is clean, dry, and your vacuum works well, you can keep using it. Replace it only if it is torn, permanently clogged, or your suction is weak.
