Clean your Dyson filter every month by tapping it over a trash can, then rinsing it under cold water until the water runs clear
A clogged filter cuts your Dyson's suction in half and can damage the motor over time. The good news: cleaning takes five minutes and costs nothing. Most Dyson models use the same basic filter—a pleated cylinder that traps dust before air leaves the machine. When you see suction drop or the filter turns gray instead of white, it is time to clean.
You do not need to buy a replacement filter every time. A proper rinse restores most of the suction. You will only replace the filter once every 12 months under normal use, or sooner if you have pets or a dusty home.
Key Takeaways
- Remove the filter by twisting the top counterclockwise—it sits on top of the motor head on most upright models and on the side of the canister on cordless models.
- Tap the filter firmly over a trash can to dislodge loose dust, then rinse under cold running water until the water runs completely clear.
- Never use hot water, a washing machine, or a dishwasher, as heat damages the filter material and voids the warranty.
- Let the filter air-dry completely—at least four hours, or overnight—before putting it back in the vacuum.
- If the filter still looks gray or suction is still weak after cleaning and drying, the filter has reached the end of its life and needs replacement.
Locate and remove the filter
The filter location depends on your Dyson model. On upright vacuums (V7, V8, V10, V11, V15), the filter sits on top of the motor head. On cordless stick models, it is usually on the side of the canister near the handle. Check your model number on the back of the machine if you are unsure.
Unplug the vacuum or make sure the battery is removed. Twist the filter cap counterclockwise—it will come free after a quarter turn. Pull the filter straight out. You will see a white or light gray pleated cylinder. If it looks dark gray or black, it is overdue for cleaning.
Tap out loose dust over the trash
Hold the filter over an open trash can with the pleated side facing down. Tap the top and sides firmly with your palm or knuckles for 10 to 15 seconds. You will see a cloud of dust come out. This step removes the bulk of the debris and makes rinsing faster.
Do not bang the filter against the edge of the trash can—this can crack the pleats. Use a steady tapping motion instead. If the filter is very clogged, tap for a full 20 seconds.
Rinse under cold running water
Hold the filter under a cold water faucet with the pleated side facing up. Let water run over the top and sides for 10 to 15 seconds. Gently rub the pleats with your other hand to help water flow through. Flip the filter and rinse the bottom side the same way.
Keep rinsing until the water running out is completely clear—no dust or discoloration. This usually takes 30 to 60 seconds total. If the water is still cloudy after a minute of rinsing, tap the filter again over the sink and rinse once more.
Never use hot water. Heat damages the filter material and can void your warranty. Cold water is all you need. Do not use a pressure washer, soak the filter in water, or put it in a washing machine.
Dry the filter completely before reinstalling
Shake the filter gently to remove excess water, then stand it upright on a clean, dry surface. A kitchen counter, windowsill, or bathroom tile works well. Let it air-dry for at least four hours. Overnight drying is better—it ensures no moisture remains inside the pleats.
Do not use a hair dryer, oven, or direct sunlight to speed up drying. The filter must dry naturally. If you reinstall a damp filter, moisture can damage the motor and create mold inside the vacuum.
Reinstall the filter and test suction
Once the filter is completely dry, line it up with the filter cap on top of the motor head (or on the side of the canister). Push it straight in, then twist the cap clockwise until it is snug. You will feel a slight resistance—do not force it.
Plug in the vacuum or reinsert the battery. Turn it on and test the suction on a small area of carpet. You should notice a clear improvement. If suction is still weak, the filter may have reached the end of its life and needs replacement.
When to replace instead of clean
A filter lasts about 12 months with regular cleaning. If the filter still looks gray or dark after drying, or if suction does not improve after a thorough rinse and dry, replacement is your only option. Dyson sells replacement filters for $30 to $50 depending on your model.
Order the correct filter for your model number—Dyson makes different filters for different machines. Install it the same way you removed the old one: push it in and twist the cap clockwise until snug.
Frequently Asked Questions
How often should I clean the filter?
Clean the filter once a month under normal use. If you have pets, a large home, or allergies, clean it every two weeks. You will notice suction drop when the filter needs cleaning—that is your signal to rinse it.
Can I use soap or vinegar to clean the filter?
No. Use only cold water. Soap leaves residue that clogs the pleats further, and vinegar can damage the filter material. Cold water alone removes all the dust that rinsing can remove.
What if water still comes out cloudy after multiple rinses?
If the filter is very old or heavily used, some fine dust may not rinse out completely. Let it dry anyway—the remaining dust will not harm the vacuum. If suction is still poor after the filter dries, the filter has worn out and needs replacement.
Can I use the vacuum while the filter dries?
No. Running the vacuum without a filter, or with a damp filter, damages the motor. Always wait until the filter is completely dry before using the machine. This usually takes four to eight hours.
Do I need to clean the filter if I just bought a new Dyson?
Yes. New Dyson vacuums come with a filter that has dust from manufacturing and testing. Rinse it once before first use to get the best suction from day one.
