Clean your Dyson filter by tapping it over a bin, rinsing it under cold water, and letting it dry completely before reinstalling
Dyson filters clog with dust and lose suction over time. A blocked filter forces the motor to work harder, reduces airflow, and can damage the machine if left uncleaned. Most Dyson models let you access the filter in under a minute without tools. The process is the same across uprights, cordless handhelds, and cylinder models: remove it, tap out loose dust, rinse it, dry it fully, and put it back.
How often you clean depends on use. Daily vacuuming in a busy household means cleaning the filter every two weeks. Light use means monthly cleaning is enough. If suction drops suddenly between scheduled cleanings, check the filter first — it is usually the culprit.
Key Takeaways
- Remove the filter by twisting or pressing the release button on your specific Dyson model, then tap it firmly over a bin to dislodge loose dust.
- Rinse the filter under cold running water only — never use hot water, as it can damage the filter material and reduce its lifespan.
- Let the filter air-dry completely for at least 4 to 5 hours, or overnight, before putting it back in the vacuum.
- Do not use a washing machine, dishwasher, or compressed air on the filter, as these damage the pleats and void your warranty.
- Replace the filter every 12 months even if it looks clean, because microscopic particles reduce efficiency over time.
Locate and remove the filter on your Dyson model
The filter location varies by model type. On upright Dyson vacuums, the filter sits at the top of the machine near the dust bin. On cordless V-series models (V15, V11, V10, V8), it is usually on the side or back of the main unit. On cylinder models, it is often mounted on top of the bin itself. Check your manual or the Dyson website for your exact model number if you are unsure.
To remove it, look for a release button or a twist-lock mechanism. Most Dyson filters have a large button you press once to unlock the filter, which then slides or pulls straight out. Some older models require a quarter-turn twist clockwise or counterclockwise. Do not force it — if it does not move easily, you are turning or pressing the wrong part. Once released, the filter should come free in your hand.
Tap out loose dust over a bin
Hold the filter over a rubbish bin or outside over a garden. Tap the filter firmly on the side of the bin 5 to 10 times. You will see a cloud of dust come out. This step removes the bulk of trapped dust and makes the rinsing step faster and more effective.
Tap the pleated sides of the filter, not the flat ends. The pleats are where dust collects, and tapping them dislodges particles trapped between the folds. If dust is caked on heavily, tap a bit harder, but do not bang it so hard that you dent or crease the pleats — that reduces the filter's surface area and its ability to trap particles.
Rinse the filter under cold running water
Hold the filter under a cold tap and let water run over it for 10 to 15 seconds. Rotate the filter so water hits all sides. You can gently rub the pleats with your fingers to help loosen stubborn dust, but do not scrub hard or use a brush. The goal is to rinse away fine dust particles, not to scour the filter material.
Use cold water only. Hot water can warp the plastic frame and damage the filter material, shortening its life and potentially voiding your warranty. Do not soak the filter in a bucket or sink — flowing water is more effective and faster. If the water coming out is still visibly dirty after 15 seconds, rinse for another 10 seconds, but most filters come clean quickly.
Dry the filter completely before reinstalling
Shake off excess water gently and stand the filter upright on a clean, dry surface. Let it air-dry for at least 4 to 5 hours, or overnight if possible. Do not use a hair dryer, oven, or radiator to speed up drying — heat can damage the filter material and the plastic frame. Patience is the safest approach.
The filter must be completely dry before you put it back in the vacuum. Installing a damp filter can damage the motor and create mold inside the machine. If you are in a hurry and need the vacuum sooner, have a spare filter on hand so you can use one while the other dries. Dyson sells replacement filters for around £15 to £25 depending on the model.
Reinstall the filter and test suction
Once the filter is dry, slide or twist it back into place until you hear or feel it click or lock. The filter should sit flush with no gaps. Turn on the vacuum and check that suction feels normal. If suction is still weak after a fresh filter cleaning, the blockage may be elsewhere — check the dust bin, the hose, and the brush bar for tangles or debris.
Make a note of when you cleaned the filter. If you clean it regularly, you will notice suction improves noticeably after each cleaning, which tells you the process is working. Over time, even with regular cleaning, the filter will lose some efficiency. When you notice suction does not bounce back as much after cleaning, it is time to replace the filter with a new one.
When to replace the filter instead of cleaning it
Dyson recommends replacing the filter every 12 months, even if it still looks reasonably clean. Microscopic particles accumulate in the pleats and reduce airflow gradually. You may not notice the loss of suction day to day, but a new filter will feel noticeably stronger than a cleaned one that is a year old.
Replace the filter sooner if you notice any of these signs: the filter has visible tears or holes, the pleats are permanently creased or flattened, the plastic frame is cracked, or suction does not improve after cleaning and drying. A damaged filter lets dust bypass the filtration system and reach the motor, which can cause long-term damage. Replacement filters are widely available online and in shops, and installation takes the same 30 seconds as cleaning.
What not to do when cleaning your Dyson filter
Never use hot water, as it warps the plastic and degrades the filter material. Never use a washing machine or dishwasher, which will destroy the filter. Never use compressed air or an air compressor, which forces dust deeper into the pleats instead of removing it. Never scrub the filter with a brush or cloth, as this damages the delicate material. Never use soap, detergent, or cleaning products — water alone is all you need.
Do not reinstall the filter while it is damp. Do not leave the vacuum running without a filter, as dust will reach the motor and cause damage. Do not ignore a clogged filter in the hope it will improve on its own — a blocked filter only gets worse and forces the motor to overheat. These mistakes are common and can shorten the life of your vacuum significantly.
Frequently Asked Questions
How often should I clean my Dyson filter?
Clean the filter every two weeks if you vacuum daily, or monthly if you use the vacuum a few times a week. If you have pets or a dusty home, clean it more often. The best guide is suction — if it drops noticeably, clean the filter even if it has not been two weeks.
Can I use a vacuum to suck dust out of the filter?
No. Using another vacuum on the filter can push dust deeper into the pleats and damage the material. Tapping and rinsing are the only safe methods. Compressed air is also not recommended for the same reason.
What if my filter is still wet when I need to use the vacuum?
Do not use the vacuum with a wet filter. A damp filter can damage the motor and create mold. If you need the vacuum urgently, buy a spare filter so you always have a clean, dry one ready while the other dries.
Is it normal for the filter to look dirty even after cleaning?
Yes. Some discoloration is normal and does not mean the filter is dirty. If water runs clear after rinsing and suction is strong, the filter is clean enough. Slight yellowing or grey tint does not affect performance.
Can I wash the filter with soap or detergent?
No. Soap leaves residue that clogs the filter and reduces airflow. Cold water alone is all you need. Rinsing with water is gentler and more effective than any cleaning product.
