The fastest way to clean a Dyson filter
Most Dyson filters come out by twisting or pressing a release button near the top of the machine — check your model's manual for which. Once it's out, hold it over a trash bin and tap it firmly against the side to dislodge loose dust. Then rinse it under cool running water, tapping gently as you go. Never use hot water or a dishwasher, which can damage the filter material. Let it dry completely — at least 4 hours, or overnight — before putting it back in.
The whole process takes about 5 minutes of active work. Most Dyson owners need to clean the filter every month if they vacuum regularly, or every two weeks if they have pets or allergies. A clogged filter makes the vacuum lose suction and forces the motor to work harder, which shortens the machine's life.
Key Takeaways
- Remove the filter by twisting or pressing the release button, then tap it over a trash bin to shake out loose dust.
- Rinse under cool water only — never use hot water, a dishwasher, or cleaning products on the filter.
- Let the filter dry completely for at least 4 hours before reinstalling it, or the vacuum will not work properly.
- Clean the filter monthly with regular use, or every two weeks if you have pets or allergies.
- If water still comes out after rinsing, the filter is not clean enough yet — rinse again until the water runs clear.
Where the filter is and how to remove it
On upright Dyson models, the filter is usually in a cylindrical housing at the top of the machine. Look for a button or release lever near the handle. Press or twist it — the direction depends on your model — and the filter cartridge will pop out or slide free. Some models have the filter on the side of the canister instead.
On cordless Dyson models (V6, V7, V8, V10, V11, V15), the filter is almost always at the top of the machine. Locate the release button, press it, and twist the filter counterclockwise to unscrew it. It should come free in your hand. If it's stuck, do not force it — spray a tiny bit of water around the seam to loosen dust that may be binding it.
Keep the filter housing itself clean too. While the filter is out, use a dry cloth or soft brush to wipe the inside of the housing where the filter sits. Dust builds up there and can reduce airflow even after you clean the filter.
The right way to rinse and dry
Hold the filter over a trash bin and tap it sharply against the side 10 to 15 times. This knocks out the bulk of the dust without water. Then hold it under cool running water — not hot, not warm — and let water flow through the pleats. Gently tap the filter as the water runs, working from top to bottom. Do not squeeze or scrub the filter material itself, which can tear it.
Keep rinsing until the water running out is clear, not cloudy. This usually takes 30 seconds to a minute. If the water is still brown or gray after a full minute of rinsing, the filter is very clogged — rinse for another 30 seconds and check again.
After rinsing, gently shake the filter to remove excess water, then stand it upright on a clean, dry surface. Do not use a hair dryer, oven, or radiator to speed drying — heat damages the filter material. Let it sit for at least 4 hours, preferably overnight. You can tell it is fully dry when it feels light and no moisture comes out if you squeeze it gently.
What not to do when cleaning a filter
Never use hot or warm water. Heat breaks down the filter material and creates small holes that let dust bypass the filter and damage the motor. Cool water only.
Never use soap, detergent, or cleaning products. These leave residue that clogs the filter faster and can damage the electrostatic material that traps fine dust. Water alone is enough.
Never put the filter in a dishwasher or washing machine. The agitation and heat will destroy it. Hand rinsing is the only safe method.
Never reinstall the filter while it is still damp. A wet filter will not seal properly, and moisture can reach the motor and cause electrical damage. Always wait until it is completely dry.
When to replace the filter instead of cleaning it
A filter usually lasts 6 to 12 months with regular cleaning. After that, it starts to lose effectiveness even after rinsing. Signs that replacement is due include suction that does not improve after cleaning, a burning smell during use, or visible tears or holes in the filter material.
Dyson sells replacement filters for most models. The part number is printed on the old filter or in your manual. Prices vary by model but typically range from $30 to $80. Buying a genuine Dyson filter is worth the cost — third-party filters often do not seal properly and let unfiltered air into the motor.
If you clean your filter every month and let it dry fully before use, you can extend its life closer to the 12-month mark. Neglecting to clean it regularly shortens its life to 6 months or less.
Cleaning the rest of the vacuum while you are at it
While the filter is drying, clean the other parts that collect dust. Empty the canister or dust cup by pressing the release button and tapping the contents into a trash bin. Wipe the inside of the canister with a dry cloth to remove dust coating.
Check the brush bar on the head for hair and lint wrapped around it. Use scissors or a seam ripper to cut away any tangles, then wipe the bar with a damp cloth. A clogged brush bar reduces suction almost as much as a dirty filter.
If your model has a pre-filter (a smaller filter before the main one), rinse that too under cool water. Not all models have one, so check your manual. If yours does, clean it at the same time as the main filter.
Frequently Asked Questions
How often should I clean my Dyson filter?
Clean it every month if you vacuum once or twice a week. If you have pets, allergies, or use the vacuum more often, clean it every two weeks. If suction drops noticeably between cleanings, that is a sign to clean more often.
Can I use vinegar or baking soda to clean the filter?
No. Vinegar and baking soda leave residue that clogs the filter faster than dust does. Cool water is all you need. If the filter smells bad, that smell will fade once it dries completely.
What if the filter still looks dirty after rinsing?
Some discoloration is normal and does not mean the filter is not clean. If water runs clear but the filter still looks gray or brown, it is fine to use. If water is still cloudy or brown, rinse for another 30 seconds and check again.
Can I use the vacuum while the filter is drying?
No. Using the vacuum without a filter, or with a damp filter, will pull dust and moisture directly into the motor and damage it. Always wait until the filter is completely dry before turning the machine on.
Is it cheaper to replace the filter or keep cleaning it?
Cleaning is much cheaper. A replacement filter costs $30 to $80, while cleaning costs nothing. A well-maintained filter lasts 12 months or longer, so cleaning every month is the better choice unless the filter tears or stops working after cleaning.
