If you own a Dyson vacuum, you know it’s a powerful machine. To keep it working its best, you need to know how to clean Dyson vacuum filter. A clean filter is the heart of your vacuum’s suction and longevity. Neglecting it can lead to weak performance, strange smells, and even motor damage. This guide will walk you through everything you need to know, step-by-step, for all the common Dyson models.
How To Clean Dyson Vacuum Filter
This is the core process that applies to most modern Dyson cyclonic vacuums, like the V-series, Outsize, Animal, and cordless models. The filter is usually a purple or grey cylinder. Always check your manual first, as steps can vary slightly.
What You’ll Need
- Cool, clean tap water
- A bowl or sink
- Your hands (no brushes or tools!)
- A dry, warm place to air dry (for at least 24 hours)
Step-by-Step Cleaning Instructions
1. Remove the Filter
First, turn off and unplug your vacuum. For cordless sticks, remove the battery. Locate the filter compartment. It’s often at the top of the cyclone or near the handle. Twist or pull the filter to release it from it’s housing. Be gentle.
2. Rinse Under Cold Water
Hold the filter under a cold tap. Use only cold water, as hot water can damage the fine material. Rinse the outside thoroughly, letting the dirty water flow out. Do not use any soap, detergent, or cleaning chemicals. They can clog the filter or leave a residue.
3. Wash the Interior
Place the filter in a bowl of cold water. Gently agitate it with your hand. You’ll see the water turn grey or black. This is the fine dust being released. Continue rinsing and soaking until the water runs clear. This might take several minutes. Squeeze the filter gently—never twist or wring it.
4. The Most Important Step: Drying
Shake off the excess water. Place the filter in a warm, dry place with good air flow. It must air dry naturally for at least 24 hours. Do not use a hair dryer, oven, microwave, or radiator. Do not put it back in the vacuum while damp. This can cause mold and motor damage.
5. Reinstall the Filter
Once the filter is completely and utterly dry—this is non-negotiable—you can reinstall it. Make sure it clicks securely into place. Your Dyson is now ready for peak performance.
Cleaning the Pre-Motor Filter (On Some Models)
Many Dyson vacuums have a second, smaller pre-motor filter. It’s often a rectangular sponge-like filter located near the main one. Check your manual to see if your model has it.
- Remove it carefully.
- Rinse it under cold water until the water runs clear.
- Gently squeeze out the water (don’t twist).
- Let it air dry fully for 24 hours before reinstalling.
How Often Should You Clean the Filter?
Dyson recommends washing the filter at least once a month. If you vacuum frequently or have pets, you might need to do it every two weeks. A good rule of thumb is to check it monthly. If it looks grey or dusty, it’s time for a wash.
Cleaning Different Types of Dyson Filters
Not all Dyson filters are the same cylinder shape. Here’s how to handle other common types.
Cleaning the Dyson Cinetic Filter
Some larger canister models have Cinetic filters. These are designed to not need washing. Instead, you “shake” them clean over a trash can. The official advice is to never wash Cinetic filters, as it can damage the oscillating tips. Just give them a good tap to dislodge dust.
Cleaning Older Dyson Ball Filters
Older upright Dyson Ball models often have a pleated, paper-like post-motor filter (usually HEPA) and a pre-motor foam filter.
- Foam Pre-Filter: Rinse in cold water, squeeze dry, and air dry.
- Pleated HEPA Filter: Do NOT wash this. You can gently tap it against the inside of a trash can to remove loose dust. Replace it every 6-12 months depending on use.
Cleaning Dyson Purifier Filters
This is for air purifiers, not vacuums, but it’s a common question. The carbon and HEPA filters in a Dyson purifier are not washable. You must replace them according to the machine’s indicator or the schedule in the manual. Only the pre-filter mesh can be wiped clean with a damp cloth.
Common Mistakes to Avoid
Making these errors can ruin your filter or your vacuum.
- Using Hot Water: This can melt the glue or warp the filter material.
- Using Soap or Cleaners: They clog the microscopic pores.
- Not Drying for 24 Hours: A damp filter is the #1 cause of motor failure and bad smells.
- Putting It in the Dishwasher or Washing Machine: The agitation and heat will destroy it.
- Using a Brush or Tool: You’ll tear the delicate material.
- Twisting to Wring It Out: Always squeeze gently instead.
Troubleshooting Filter Problems
My Vacuum Has Weak Suction
A clogged filter is the most likely culprit. Remove and clean it following the steps above. Also, check the bin, hoses, and brush bar for blockages. A full bin can also reduce suction power dramatically.
There’s a Bad Smell When I Vacuum
This usually means the filter was put back in while damp, causing mildew. Wash the filter again and let it dry completely for 48 hours in a sunny spot if possible. Also, empty the dust bin regularly and rinse it out with cold water (let it dry fully too).
The Vacuum Shuts Off or Overheats
A dirty filter restricts airflow, causing the motor to overheat and the thermal cut-off to engage. Clean the filter immediately and let the vacuum cool down for an hour before trying it again with the clean, dry filter installed.
Water Won’t Run Clear
Some fine dust is very stubborn. Keep rinsing and gently massaging the filter under a slow stream of water. Patience is key. It may never be perfectly white again, but the water should be mostly clear.
Maintenance Schedule for Your Dyson
Filter cleaning is just one part of upkeep. Here’s a simple schedule to follow.
- After Every Use: Empty the dust bin. Don’t let it fill past the “Max” line.
- Weekly: Check the brush bar for hair and thread tangles. Clear any blockages in the hose or wand.
- Monthly: Wash the main filter(s) following the cold-water method. Wipe down the outside of the vacuum.
- Every 6 Months: Give the entire vacuum a more thorough check. Rinse the dust bin and let it dry. Inspect filters for wear and tear.
- Yearly: Consider replacing any non-washable HEPA filters. Check for parts that may need replacing, like the brush bar.
FAQ Section
Can I wash my Dyson filter?
Yes, most Dyson vacuum filters are washable. You must use cold water only and let them air dry for at least 24 hours. Always confirm in your user manual first.
How do you clean a Dyson HEPA filter?
Most Dyson HEPA filters are not washable. For the pleated paper ones, you can only tap them gently to remove dust. The washable purple/grey cyclonic filters are often not true HEPA filters. Check your model’s manual to be certain.
What happens if you don’t clean Dyson filter?
Suction power will drop significantly. The motor will have to work harder, leading to overheating and potentially early motor failure. It can also cause unpleasant odors to blow back into your room.
Can I use warm water to clean my Dyson filter?
No. You should only use cold tap water. Warm or hot water can damage the filter’s material and adhesive, ruining it’s ability to trap fine dust.
How long do Dyson filters last?
The washable main filters can last for years with proper monthly cleaning. Pre-motor foam filters also last a long time. Non-washable HEPA filters typically need replacement every 6 to 12 months, depending on use.
Why is my Dyson still losing suction after cleaning the filter?
There might be another blockage. Check the entire air path: the bin opening, the cyclone shroud, the hose, the wand, and the cleaner head. Also, ensure the filter is 100% dry. Even a slightly damp filter can restrict airflow.
Keeping your Dyson’s filter clean is the simplest and most effective way to protect your investment. It takes just a few minutes of hands-on time, plus the patience to let it dry completely. By following these straightforward steps, you’ll ensure your vacuum has powerful suction for years to come, making your cleaning sessions quicker and more effective. Remember, when in doubt, always refer to the official Dyson guide for your specific model number.
