Clean your Dyson filter by tapping it over a bin, then rinsing it under cold water until the water runs clear
The filter on a Dyson vacuum traps dust and particles so fine they would otherwise escape back into the air. Over time, the filter clogs and your vacuum loses suction. Cleaning it takes about five minutes and costs nothing. Most Dyson models let you do this yourself without tools — you just need access to a sink and a bin.
The exact steps depend slightly on which Dyson model you own, but the principle is the same across all of them: remove the filter, tap out loose dust, rinse with water, let it dry completely, and put it back. A clogged filter is the most common reason a Dyson loses power, so cleaning it regularly — roughly every month if you use the vacuum daily — keeps the machine working as it should.
Key Takeaways
- Remove the filter by twisting or unclipping it depending on your model, then tap it firmly over a bin to dislodge dust.
- Rinse the filter under cold running water until water flows through it clear, which usually takes one to two minutes.
- Never use hot water or a washing machine, and never put the filter in a dryer — heat damages the filter material.
- Let the filter air-dry completely (at least four hours, ideally overnight) before putting it back in the vacuum.
- Clean your filter monthly if you vacuum daily, or whenever you notice the suction dropping noticeably.
How to remove the filter from your Dyson
The filter sits inside the main body of the vacuum, usually near the top or on the side. On upright models like the V15 or V11, look for a cylindrical filter that sticks up from the dust bin area. On cordless stick models, the filter is often accessed from the back or side of the motor head.
To remove it, grip the filter firmly and twist it counterclockwise — most Dyson filters unscrew like a jar lid. Some newer models use a clip or release button instead; if twisting does not work, look for a small button or lever near the filter base and press it while pulling gently. Once loose, pull the filter straight out. Do this over a bin or sink because dust will fall as you remove it.
Tapping out loose dust
Hold the filter over a bin or outside (if you have a yard) and tap it firmly on the bottom and sides. The goal is to dislodge the thick layer of dust that has built up on the outside. Tap it the way you would tap a flour sifter — not hard enough to damage the filter, but hard enough that you see dust falling out. This step removes the bulk of the debris and makes the rinsing step faster.
If the filter looks very clogged — so packed with dust that you can barely see the white or gray filter material underneath — spend a bit longer tapping. You may need to tap it 20 or 30 times. The more dust you remove by tapping, the easier the water rinse will be.
Rinsing the filter under running water
Hold the filter under a cold tap and let water run through it from the inside out. Start with the tap on low to medium pressure — high pressure can damage the delicate filter material. Rotate the filter as you rinse so water reaches all sides. You should see dirty water running out at first; keep rinsing until the water runs clear, which usually takes one to two minutes.
Pay special attention to the pleats (the ridges running along the filter). Dust collects in these folds, so use your fingers gently to help water flow through them. Do not scrub hard or use a brush — the filter material is fragile and can tear. If water is not flowing through easily after a minute of rinsing, go back and tap the filter over the bin again, then rinse once more.
Drying the filter completely
After rinsing, shake off excess water and stand the filter upright on a clean, dry surface — a kitchen towel works well. Let it air-dry for at least four hours, though overnight is better. The filter must be completely dry before you put it back in the vacuum, because moisture can damage the motor and reduce suction.
Never use a hair dryer, oven, or any heat source to speed up drying. Never put the filter in a washing machine or dryer. Heat damages the filter material and can warp it so it no longer fits properly. If you are in a hurry and need to use your vacuum, clean the filter in the evening so it can dry overnight while you sleep.
Putting the filter back and testing suction
Once the filter is completely dry, line it up with the opening in the vacuum and push it in straight. Then twist it clockwise (or use the clip or button, depending on your model) until it is snug. You should hear or feel a click when it is seated properly. Do not force it — if it does not turn easily, pull it out and check that it is lined up correctly.
Turn on the vacuum and test the suction. You should notice an when ready improvement if the filter was clogged. If suction is still weak after cleaning, the filter may be damaged or there may be a blockage elsewhere in the vacuum — check the hose and the dust bin for clogs.
How often to clean your Dyson filter
If you use your Dyson daily on carpet or hard floors, clean the filter once a month. If you use it less often or mostly on hard floors, every six to eight weeks is fine. The best sign that it is time to clean is when you notice suction dropping, even if you have not emptied the dust bin recently.
Some Dyson models have a filter-cleaning alert light that turns on when the filter needs attention. If your vacuum has one, follow that signal. If not, set a calendar reminder for the first of each month so you do not forget. A clean filter keeps your vacuum running at full power and extends the life of the motor.
Frequently Asked Questions
Can I wash the filter in a washing machine?
No. Washing machines use hot water and agitation that damage the filter material. Always rinse by hand under cold running water only. The filter is designed to be rinsed, not washed, and hand rinsing takes just a couple of minutes.
What if the filter is torn or has holes in it?
A torn filter no longer blocks dust properly and should be replaced. Dyson sells replacement filters for most models, and they cost between $30 and $80 depending on the model. Order the correct filter for your vacuum model number before the old one fails completely.
How do I know if my filter is dry enough to use?
Touch the filter with your hand — it should feel completely dry, not damp or cool. If you are unsure, wait another hour or two. Using a damp filter can damage the motor and is not worth the risk of a few extra minutes of waiting.
Why is my Dyson still losing suction after I cleaned the filter?
Check the hose and the dust bin for blockages — hair and debris can clog these areas. Empty the dust bin completely and look inside the hose by holding it up to a light. If you see a clog, use a straightened coat hanger or plumbing snake to push it through.
