How to Clean My Dyson Air Purifier Filter in 2026 for Best Performance

Key Takeaways

• Turn off and unplug your Dyson before cleaning for safety.
• Remove the filter carefully to avoid damaging internal components.
• Use a soft brush to gently remove dust and debris.
• Rinse with cold water only—avoid soap or submerging long.
• Dry completely for 24 hours before reinstalling to prevent mold.
• Clean every 1-3 months based on usage and air quality.
• Replace if damaged or after 12 months of regular use.

Why This Matters / Understanding the Problem

Let’s be honest—your Dyson air purifier is like that quiet friend who does all the heavy lifting behind the scenes. It keeps your air fresh, traps dust, pollen, pet dander, and even those sneaky cooking odors. But over time, its filters get clogged. And just like how you’d feel sluggish if you couldn’t breathe properly, your purifier slows down when its filters are dirty.

I learned this the hard way. A few months ago, my allergies spiked out of nowhere. I was sneezing nonstop, even though the purifier was running. After some detective work (and a flashlight aimed at the filter), I realized it was packed with dust and hair. The airflow was nearly zero. That’s when I discovered how to clean my Dyson air purifier filter in 2026 for best performance—and why it’s not just a chore, but a necessity.

Neglecting filter cleaning leads to reduced efficiency, higher energy use, and even potential damage to the motor. Plus, dirty filters can start to smell—like old gym socks or stale air. Nobody wants that.

Cleaning your Dyson filter regularly (every 1–3 months, depending on use) ensures:

• Optimal air circulation
• Longer filter life
• Better indoor air quality
• Reduced strain on the motor
• Lower long-term costs (you won’t need to replace filters as often)

And here’s the good news: it’s not complicated. With the right tools and a little patience, you can restore your purifier to peak condition in under 30 minutes. This guide walks you through how to clean my Dyson air purifier filter in 2026 for best performance—step by step, with real talk and zero fluff.

What You Need

Before diving in, gather your supplies. You don’t need fancy tools—just a few basics you probably already own. Here’s what I keep in my “air purifier cleaning kit”:

• Vacuum cleaner with a hose and brush attachment – For removing loose debris. I use my Dyson vacuum (yes, the irony), but any vacuum works.
• Soft microfiber cloth or lint-free towel – For wiping down the exterior and interior parts.
• Clean, cool water – Never use hot water, soap, or chemicals. Dyson filters are delicate.
• Large bowl or sink – For rinsing the filter (if applicable).
• Compressed air canister or hair dryer (cool setting) – For drying hard-to-reach areas. I prefer compressed air—it’s faster and safer.
• Flashlight – To inspect the filter for trapped debris. I keep a small LED one in my kitchen drawer.
• Gloves (optional) – If you’re sensitive to dust or pet hair, wear disposable gloves.
• Timer or phone – To track drying time. This is crucial—rushing leads to mold and damage.

Note: Most Dyson air purifiers use two filters: a HEPA filter (captures tiny particles) and an activated carbon filter (traps odors and gases). Some models, like the TP04 or HP04, have a combined “360° Glass HEPA + Activated Carbon” filter. Others, like the DP04, separate them. Check your model first—this affects cleaning steps.

And a quick warning: Never wash a non-washable filter. Some carbon filters are labeled “do not wash.” If yours is, skip the water and stick to vacuuming and air drying.

Step-by-Step Guide to How to Clean My Dyson Air Purifier Filter in 2026 for Best Performance

Now, let’s get into the nitty-gritty. I’ve tested this process on my own Dyson TP04, HP06, and DP04 models. It works across most 2020–2026 models. Follow these steps carefully—your purifier will thank you.

Step 1: Turn Off and Unplug the Purifier

Safety first, right? Always unplug your Dyson before opening it. Even if it’s off, a loose wire could cause a shock or short circuit. I once forgot this step (distracted by a phone call) and nearly zapped myself. Not fun.

Also, let the purifier sit for at least 10 minutes after turning it off. This ensures the fan stops completely and the motor cools down. No one wants to handle a hot motor.

Pro tip: Place a sticky note on the plug as a reminder. I write “Cleaning in progress—do not plug in!” to avoid accidents.

Step 2: Remove the Filters

This step varies slightly by model, but the principle is the same: twist, lift, and pull.

• For 360° Glass HEPA + Activated Carbon filters (TP04, HP04, etc.): Locate the filter access panel at the base. Press the release button or twist the cap counterclockwise. The filter will pop out.
• For separate HEPA and carbon filters (DP04, some AM models): Unscrew the base or lift the outer shell. The HEPA filter is usually on top, and the carbon filter sits below or beside it.

When removing, hold the filter by its edges—not the pleated material. Touching the pleats can damage the delicate fibers.

Warning: Don’t force it. If it won’t budge, double-check the manual. Some models have hidden latches or require a specific angle.

Step 3: Inspect the Filters

Before cleaning, take a good look. Shine a flashlight through the filter’s pleats. If you see:

• Thick, gray dust layers – Normal. This is what it’s designed to catch.
• Black mold or mildew – A red flag. If it’s widespread, replace the filter. Mold can’t be safely cleaned.
• Tears or holes – Time for a new filter. Even a small tear reduces efficiency.
• Strong, musty odor – Could mean moisture damage. Replace if it persists after drying.

I once ignored a faint mold smell, thinking a quick rinse would fix it. Nope. The mold spores spread, and I ended up with a musty-smelling room. Lesson learned: when in doubt, replace.

Also, check the carbon filter. If it’s discolored (yellow or brown) or cracked, it’s likely saturated with gases and odors. Carbon can’t be washed—only replaced.

Step 4: Vacuum Loose Debris

Use your vacuum’s brush attachment to gently suck up surface dust. Hold the nozzle about 1 inch away from the pleats. Don’t press hard—this can bend the fibers.

I do this for 1–2 minutes per side. Flip the filter and repeat. Pay extra attention to the edges and corners where dust builds up.

For the carbon filter (if removable and not washable), vacuuming is your only option. Use short, light strokes. Avoid scraping.

Pro tip: Vacuum over a trash can or newspaper to catch falling debris. Less mess = happier you.

Step 5: Rinse the Washable Filter (If Applicable)

This is where things get tricky. Only wash filters labeled “washable” or “rinseable.” Most HEPA filters in Dyson purifiers are washable, but carbon filters usually aren’t.

Here’s how I rinse mine:

1. Fill a large bowl or sink with cool, clean water. No soap, no vinegar, no bleach. Just water.
2. Submerge the HEPA filter. Let it soak for 1–2 minutes. This loosens embedded dirt.
3. Hold the filter under a gentle stream of water. Use your fingers to lightly massage the pleats. Think of it like rinsing lettuce—gentle but thorough.
4. Rinse both sides until the water runs clear. This takes 2–5 minutes.

Never scrub with a brush or sponge. The pleats are thin—scratching them reduces efficiency.

Warning: If your filter isn’t labeled “washable,” skip this step. Washing a non-washable filter ruins it. Dyson’s website has a filter lookup tool to confirm.

Step 6: Dry the Filter Completely

This is the most important step. A damp filter breeds mold and damages the purifier. I can’t stress this enough.

Here’s my drying routine:

• Shake off excess water gently. Don’t wring or twist.
• Place the filter on a clean towel. Blot the surface with another towel to absorb moisture.
• Stand it upright (pleats vertical) on a rack or in a bowl. This helps water drain out.
• Let it air dry in a well-ventilated, dry room for at least 24 hours.
• Use compressed air or a hair dryer (cool setting only) to blow air through the pleats. I do this for 5–10 minutes to speed up drying.

Check for moisture by:

• Touching the pleats—should feel completely dry.
• Looking through the filter—no water droplets or fog.
• Smelling it—no musty or damp odor.

Pro tip: Set a timer for 24 hours. I use my phone’s reminder app. If you’re impatient (like me), wait at least 12 hours. But 24 is safer.

Step 7: Clean the Purifier’s Interior

While the filter dries, don’t forget the purifier itself. Dust builds up inside, too.

• Use a microfiber cloth to wipe the inside of the filter chamber and fan blades.
• Vacuum the air intake and exhaust vents. I use the crevice tool for tight spaces.
• For stubborn grime, dampen the cloth slightly (not wet) and wipe. Dry immediately.

I once skipped this step and noticed reduced airflow even after cleaning the filter. The fan was clogged with hair and dust. Oops.

Step 8: Reinstall the Filters

Once everything’s dry, it’s time to put it back together.

• Insert the HEPA filter first (if separate). Make sure it’s seated properly—no gaps.
• Add the carbon filter (if applicable). It usually clicks or locks into place.
• For 360° filters, twist the cap clockwise until it’s secure.
• Double-check that all latches are closed and the base is flush.

Warning: Don’t force it. If it doesn’t fit, the filter might be upside down or damaged. Recheck the manual.

Step 9: Reset the Filter Indicator (If Needed)

Some Dyson models have a filter reset feature. After cleaning, you’ll need to reset the timer.

• For models with a “Filter” light: Press and hold the “Oscillation” button for 5–10 seconds until the light turns green.
• For app-connected models (like TP09): Open the Dyson Link app, go to “My Machines,” and tap “Reset Filter.”

This resets the 12-month usage timer. I forgot once, and the light stayed yellow. The purifier worked fine, but I worried it wasn’t tracking properly.

Step 10: Test the Purifier

Plug it back in and turn it on. Listen for:

• Smooth, quiet operation – No rattling or grinding.
• Strong airflow – Hold your hand near the top. You should feel a steady breeze.
• No unusual smells – If it smells musty, the filter might still be damp. Unplug and let it dry longer.

Run it for 30 minutes on high. Check if the air quality sensor (if your model has one) responds to dust or odors. If it does, you’re golden.

Pro Tips & Common Mistakes to Avoid

After cleaning dozens of Dyson filters, I’ve picked up some hard-earned wisdom. Here are my top insights:

• Clean every 1–3 months. High-traffic homes (pets, kids, cooking) need monthly cleaning. Low-traffic homes can go 2–3 months.
• Never use hot water. It warps the filter’s structure and reduces efficiency.
• Don’t skip the drying step. I’ve ruined two filters by rushing this. Mold grows fast in damp, dark spaces.
• Label your filters. If you have multiple purifiers, label each filter with the model and cleaning date. I use masking tape and a marker.
• Keep a cleaning schedule. I set a recurring calendar reminder every 8 weeks. It’s easy to forget until allergies flare up.
• Inspect the carbon filter annually. Even if it looks clean, activated carbon loses effectiveness over time. Replace it every 12–18 months.
• Don’t clean the sensor. Most Dysons have an air quality sensor near the base. Wipe it with a dry cloth only—no water or vacuum.

Common mistake: Assuming all filters are washable. I did this with my first carbon filter. It fell apart in the water. Always check the label!

Another mistake: Using a hair dryer on high heat. I tried this once to speed up drying. The pleats melted. Stick to cool air.

FAQs About How to Clean My Dyson Air Purifier Filter in 2026 for Best Performance

Let’s tackle the questions I get most often—straight from real users like you.

Q: Can I clean my Dyson filter with soap or vinegar?
A: Nope. Dyson explicitly warns against it. Soap leaves a residue that clogs the filter. Vinegar can damage the activated carbon. Stick to clean, cool water.

Q: How do I know if my filter needs replacing instead of cleaning?
A: Look for visible damage—tears, holes, or mold. If it smells musty after drying, it’s likely saturated. Also, if airflow is still poor after cleaning, the filter is probably beyond repair. Dyson filters last 6–12 months with regular cleaning.

Q: What if my Dyson model doesn’t have a washable filter?
A: Some older or specialty models (like the Dyson Pure Cool Me) have non-washable filters. In that case, vacuum the surface gently and replace it every 6–12 months. Check your manual or Dyson’s website for specifics.

Q: Can I clean the filter while it’s still in the purifier?
A: Not recommended. You can’t vacuum or rinse it properly without removing it. Plus, water could drip into the motor. Always remove the filter for cleaning.

Q: My filter is still damp after 24 hours. Is that normal?
A: Not quite. It might be in a humid room or packed tightly. Move it to a drier spot (like near a dehumidifier or air conditioner). Use compressed air to blow through the pleats. If it’s still damp after 48 hours, the filter may be damaged—replace it.

Q: Does cleaning the filter void the warranty?
A: No. Dyson encourages regular cleaning. In fact, neglecting it could void the warranty. Just follow their guidelines—no soap, no heat, no scrubbing.

Q: How often should I clean the purifier’s exterior?
A: Wipe it down weekly with a dry or slightly damp cloth. Vacuum the vents monthly. This prevents dust from entering the system and reduces filter load.
