If your Dyson vacuum is losing suction or sounding different, a dirty filter is often the culprit. Learning how to clean the filter on Dyson vacuum is the key to restoring its power and keeping your machine running for years. It’s a simple task that many owners overlook, but it makes a huge difference. This guide will walk you through every step for all popular Dyson models. We’ll cover how to find, remove, wash, and dry your filter correctly.
How To Clean The Filter On Dyson Vacuum
This main process applies to most modern Dyson cordless and upright vacuums. The exact location of your filter might vary slightly, but the cleaning principles remain the same. Always check your user manual for model-specific instructions first.
Step 1: Safety First & Preparation
Before you start, unplug your vacuum if it’s a corded model. For cordless stick vacuums, remove the battery pack completely. This prevents any accidental starts and keeps you safe. You’ll also need a few supplies:
- A clean sink or basin
- Lukewarm water (never hot)
- No detergent or cleaning chemicals
Step 2: Locating and Removing the Filter
Most Dyson vacuums have at least one main filter, and many have two. The pre-motor filter protects the engine from dust. The post-motor filter cleans the air before it exits the machine.
- For stick vacuums like the V7, V8, V10, V11, and V15: The main filter is usually on top of the cyclone bin or near the handle. Twist or pull it to release.
- For uprights like the Ball Animal or Cinetic models: The filter is often found near the ball or behind a cover at the back of the machine.
- For canister vacuums: Check near the top of the canister unit.
Gently remove the filter by following the arrows or release marks on the housing. If it’s stuck, don’t force it—double-check the manual.
Step 3: The Correct Washing Technique
This is the most important part. Using the wrong method can ruin your filter.
- Hold the filter under lukewarm running water. Run the water over the outside of the filter, not the inside center if it’s a cylinder shape. This pushes dirt out the way it came in.
- Gently squeeze and massage the filter pleats with your fingers. You’ll see brown water running out. Continue until the water runs clear.
- Do not twist, scrub, or use a brush on the filter material. This can damage the delicate fibers.
- Never, ever use soap, detergent, or disinfectant. These can clog the filter and leave a residue that you might inhale later.
What About Compressed Air?
Some people try to use compressed air to blow out a filter. This is not recommended by Dyson. It can damage the pleats and force dirt deeper into the material. Washing with water is the only method they endorse.
Step 4: Drying Thoroughly (The Non-Negotiable Step)
A wet filter will destroy your vacuum’s suction and can even damage the motor. Proper drying is critical.
- After washing, gently shake off excess water.
- Press the filter between the palms of your hands to remove more moisture. Avoid wringing it.
- Place the filter in a warm, dry, well-ventilated area. It must air dry naturally for at least 24 hours. This often takes longer than you think.
- Do not put it on a heater, in direct sunlight, in a tumble dryer, or use a hairdryer. Excessive heat can warp and shrink the filter.
Your filter must be completely, 100% bone-dry before you even think about reinstalling it. Patience here saves you from big repair bills.
Step 5: Reinstalling Your Clean Filter
Once the filter is fully dry, it’s time to put it back. Make sure it’s seated correctly in its housing. You should hear a click or feel it lock into place. A filter that isn’t sealed properly will let dusty air bypass it, reducing your vacuum’s efficiency.
How Often Should You Clean the Filter?
Dyson recommends washing the filter at least once every month for optimal performance. If you vacuum frequently or have pets, you might need to do it every two or three weeks. A good rule of thumb is to check it whenever you empty the dust bin. If it looks gray or brown, it’s time for a wash.
Cleaning Filters on Specific Dyson Models
While the core steps are universal, here are some model-specific tips to help you out.
Dyson Cordless Stick Vacuums (V Series)
These are incredibly popular, and their filters are easy to access. The main filter is usually a cylindrical unit. Some models, like the V11 and V15, also have a second, smaller filter in the bin assembly or near the cleaner head. Don’t forget to check and clean both if your model has them. After washing, let them dry with the open end facing down so water doesn’t pool inside.
Dyson Upright Vacuums (Ball Models)
Many upright Dysons have a purple pre-motor filter and a blue post-motor HEPA filter. Both need regular cleaning. The pre-motor filter might be washable, while some post-motor filters are not—always check your manual. For washable ones, follow the standard lukewarm water technique. If you have a Dyson with a “lifetime” filter, like some Cinetic models, it still needs occasional rinsing under the tap until the water runs clear.
Dyson Canister Vacuums
The filter on models like the Big Ball or Small Ball canister is typically found on top of the cyclone unit. It often twists out. The process is identical: rinse with water, squeeze gently, and dry for a full 24+ hours. Ensure the sealing gasket is clean and intact before you put it back.
Common Mistakes to Avoid
Even with good intentions, it’s easy to make a error that hurts your vacuum. Here’s what to watch out for.
Using Hot Water or Chemicals
Hot water can melt the glue or warp the filter frame. Chemicals leave behind invisible residues that clog pores and create odors. Stick to lukewarm tap water only.
Not Drying Long Enough
This is the number one mistake. Putting in a damp filter is the fastest way to get musty smells and poor suction. If you’re in a humid climate, give it 48 hours. To be sure, touch the inner material—it should feel completely dry, not cool or damp.
Forgetting Secondary Filters
Many Dysons have more than one filter. If you only clean the obvious one, performance can still suffer. Take a moment to identify all filters in your machine. Your user manual has a diagram that shows every part.
Damaging the Filter During Cleaning
Aggressive squeezing, brushing, or tapping the filter against the sink can tear the fine mesh. Treat it gently, like a delicate sponge. If the material is torn, you need to replace it immediately.
Troubleshooting: After Cleaning Your Filter
What if you’ve cleaned your filter properly, but your vacuum still isn’t working right? Here are some solutions.
Vacuum Still Has Weak Suction
If suction hasn’t improved after a filter wash and full dry, other blockages are likely. Check these areas:
- The bin opening and cyclone shroud: Debris can get compacted here.
- The hose and wand: Detach them and look through for obstructions.
- The cleaner head: Remove any hair or string wrapped around the brush bar.
- The post-motor HEPA filter: If it’s not washable, it may need replacing every few years.
Strange Noises or Overheating
A howling noise often indicates a blockage elsewhere in the system. A high-pitched whine or the machine shutting off points to an overheating motor. This can happen if a damp filter is restricting airflow, causing the motor to overwork. Turn the vacuum off, let it cool completely, and re-check that your filter is 100% dry.
Dust Blowing Back Into the Room
This is a sure sign that a filter is missing, damaged, or not installed correctly. Air is bypassing the filtration system. Power down, remove and inspect the filter for tears or improper seating. Make sure all seals are clean and the filter clicks firmly into its correct position.
When to Replace Your Dyson Filter
Even with perfect cleaning, filters don’t last forever. The material will eventually degrade. Washable Dyson filters typically need replacement every 12-18 months with normal use. Signs you need a new one include:
- Visible tears, holes, or deformation in the filter material.
- A persistent musty smell even after proper washing and drying.
- Reduced suction that doesn’t improve after cleaning the filter and checking for blockages.
- Your vacuum’s “check filter” light (on some models) remains on after maintenance.
Always use genuine Dyson replacement filters for the best fit and performance. Third-party filters may not seal properly or filter as effectively.
FAQs About Dyson Filter Cleaning
Can I wash my Dyson filter with vinegar?
No, you should not use vinegar or any other cleaning solution. Dyson explicitly instructs to use cold or lukewarm water only. Chemicals can damage the filter and void your warranty.
How long does it take for a Dyson filter to dry?
It needs a minimum of 24 hours to air dry completely. In humid or cool environments, it can take 48 hours or more. Rushing this step is the most common cause of problems after cleaning.
Why does my Dyson smell bad after I cleaned the filter?
A bad smell usually means the filter was reinstalled while still damp. Moisture inside the machine causes mildew and mold to grow. It can also happen if you used soap. You must let the filter dry fully, and never add any scents or cleaners to it.
Do all Dyson vacuums have washable filters?
Most modern Dysons have at least one washable filter, usually the pre-motor one. However, some models have a secondary HEPA filter that is not washable and must be replaced. Always refer to your specific model’s user manual to be certain.
How do I clean the filter on a Dyson without removing it?
You can’t clean it properly without removing it. Trying to wipe or vacuum the surface won’t remove the deep-seated dirt. You must take it out and wash it under running water to get it truly clean.
My filter turned yellow, is that normal?
Yes, that’s normal, especially for HEPA filters. Discoloration doesn’t mean it’s dirty or ineffective. It’s often caused by organic compounds in the air. As long as you wash it regularly and it’s not damaged, a yellow color is fine.
Keeping your Dyson’s filter clean is the simplest and most effective maintenance you can do. It protects your investment, ensures peak performance, and maintains healthy air quality in your home. By following these steps—using only water, being gentle, and allowing for a full dry—you’ll keep your vacuum working powerfully for the long haul. Set a monthly reminder on your phone to check the filter, and it will become a quick and easy habit.
