Clean your Dyson air purifier filter every 1–3 months to maintain peak performance and extend its lifespan. Use only a soft brush and cold water—never soap or submerge the entire unit—to safely remove dust and debris without damaging sensitive components. This quick, easy routine ensures cleaner air and optimal airflow in just minutes.

How to Clean Dyson Air Purifier Filter in 2026

Key Takeaways

• Turn off and unplug the purifier before cleaning for safety.
• Vacuum loose debris first to extend filter lifespan and efficiency.
• Use cold water only—never soap or heat—to avoid damage.
• Air-dry completely for 24+ hours before reinstalling the filter.
• Clean every 2–3 months or more often in high-pollution areas.
• Replace if damaged—cracks or odors mean it’s time for a new filter.

Why This Matters / Understanding the Problem

Let’s be real: your Dyson air purifier works hard. It’s quietly humming in the corner, filtering out dust, pet dander, pollen, and even that weird cooking smell from last night’s stir-fry. But after a few months, that clean air starts to feel… not so clean. You might notice a musty odor, reduced airflow, or a blinking light telling you it’s time to act.

Here’s the truth: how to clean Dyson air purifier filter in 2026 isn’t just about maintenance—it’s about breathing easier and saving money. A clogged filter forces the motor to work harder, which means higher energy bills and a shorter lifespan for your machine. Plus, a dirty filter can’t trap pollutants effectively. That defeats the whole purpose.

I learned this the hard way. I ignored the filter light for weeks, thinking, “It’s just a little dust.” Then I started sneezing more, and my cat, Luna, began scratching her face. Turns out, a saturated filter was releasing allergens back into the air. Not cool.

So, if you’ve ever wondered, “Can I clean my Dyson filter without ruining it?” or “How often should I really do this?”—you’re in the right place. Cleaning your Dyson air purifier filter is easier than you think, and doing it right keeps your air fresh and your purifier running smoothly. And in 2026, with more smart features and filter types, knowing the how to clean Dyson air purifier filter in 2026 method is more important than ever.

What You Need

Before we dive in, let’s gather the right tools. You don’t need fancy gadgets—just a few household items and a bit of patience. Here’s your quick checklist:

• Dyson air purifier (obviously!) – Check your model (TP04, HP04, TP07, etc.) to confirm filter type.
• Soft brush or microfiber cloth – For dusting the outer surfaces and pre-cleaning.
• Vacuum cleaner with a brush attachment – A handheld vacuum works great for tight spaces.
• Large bowl or sink – For soaking the filter (if applicable).
• Mild dish soap (optional) – Only for washable HEPA filters. Avoid harsh chemicals.
• Clean, dry towels – To pat dry and absorb moisture.
• Timer or phone reminder – Because drying time matters!
• Replacement filters (optional) – Keep a backup on hand if yours is beyond cleaning.

Pro Insight: Not all Dyson filters are washable. The HEPA filter is usually not—only the pre-filter (the outer mesh) is. The HEPA filter is sealed in plastic and should never get wet. I once made that mistake and had to buy a new one. Lesson learned.

Also, check your purifier’s manual or Dyson’s website to confirm your model’s filter specs. In 2026, newer models like the TP09 and HP07 have slightly different filter designs, so knowing what you’re working with is key to mastering how to clean Dyson air purifier filter in 2026.

Step-by-Step Guide to How to Clean Dyson Air Purifier Filter in 2026

Alright, let’s get into the nitty-gritty. This guide works for most Dyson air purifiers—tower, fan, and heater models—with minor adjustments. I’ll walk you through each step like we’re doing it together in your living room.

Step 1: Power Off and Unplug

First things first: turn off and unplug your Dyson. Even if it’s just for a few minutes, safety comes first. I once forgot this and accidentally hit the power button mid-clean—yikes. The motor started, and I nearly dropped the filter.

Once it’s off, give it a minute to cool down if it’s been running. This is especially important for heater models.

Tip: Place a sticky note on the plug or outlet as a visual reminder not to turn it back on until you’re done.

Step 2: Remove the Outer Cover

Most Dyson purifiers have a magnetic or snap-on cover. For tower models like the TP04 or TP07, gently pull the front or top panel. It should pop off with a soft click.

On newer 2026 models like the TP09, the cover might have a hidden latch. Look for a small indentation near the base—press it lightly to release.

Once the cover is off, you’ll see the filter assembly. Don’t rush. Take a photo with your phone. That way, if you forget how to reassemble it, you’ve got a reference.

Step 3: Take Out the Filter

Now, locate the filter. You’ll see two parts:

• Pre-filter (outer mesh) – This is the first line of defense. It catches large particles like hair and lint.
• HEPA filter (inner cartridge) – Sealed in plastic, this captures fine particles like mold spores and pollen.

For most models, the pre-filter slides out easily. The HEPA filter is usually held by a plastic frame. Gently lift it out—don’t force it. If it feels stuck, double-check for any clips or tabs.

Warning: Never remove the HEPA filter’s plastic casing. It’s designed to stay sealed. If you break it, the filter loses effectiveness.

Set both filters aside on a clean towel. This is a crucial step in how to clean Dyson air purifier filter in 2026—keeping things organized avoids confusion later.

Step 4: Clean the Pre-Filter (The Washable One)

This is the only part you can (and should) wash. The pre-filter is usually made of a fine mesh and sits outside the HEPA filter.

Here’s how:

1. Vacuum first – Use the brush attachment to remove loose dust and hair. This prevents clogging your sink.
2. Rinse under warm water – Hold it under the tap. Use your fingers to gently rub away grime. If it’s really dirty, add a drop of mild dish soap.
3. Soak (if needed) – For stubborn gunk, soak it in warm (not hot) water with a bit of soap for 10–15 minutes. Hot water can warp the mesh.
4. Rinse thoroughly – Make sure no soap residue remains. Leftover soap can create a film that traps dust faster.

After rinsing, shake off excess water. Then, lay it flat on a clean towel to air dry. Do not wring or twist—this can damage the mesh.

Pro Tip: If you have hard water, use filtered or distilled water for rinsing. Minerals can leave spots and reduce airflow.

Step 5: Dry the Pre-Filter Completely

This step is non-negotiable. A damp filter will grow mold or mildew, which you’ll breathe in when you turn the purifier back on.

Place the pre-filter on a dry towel in a warm, well-ventilated area. I like to put it near a window with indirect sunlight or use a fan to speed things up.

Let it dry for at least 12 hours—or 24 hours if it’s humid. I once tried to rush this and used a hairdryer on low heat. Big mistake. The mesh melted in one spot. Now I set a timer and walk away.

Once it’s bone-dry, it’s ready to go back in.

Step 6: Wipe Down the HEPA Filter (Do Not Wash!)

Remember: the HEPA filter is not washable. But you can still clean the outer surface.

Use a dry microfiber cloth to wipe away dust from the plastic casing. If there’s visible dirt, lightly dampen the cloth (wring it out well!) and wipe gently. Then, use a dry cloth to remove any moisture.

For stubborn dust in the crevices, use a soft brush or a cotton swab. Be gentle—those tiny pleats are delicate.

Real Talk: If the HEPA filter looks brown or smells musty, it’s time to replace it. Cleaning won’t fix a degraded filter. Dyson recommends replacing HEPA filters every 12 months (or sooner if you have pets or allergies).

Step 7: Clean the Purifier’s Interior and Exterior

While the filters dry, clean the machine itself. Use the vacuum brush to remove dust from the inside chamber where the filter sits. Pay attention to the air inlet and outlet grilles.

For the exterior, wipe with a slightly damp cloth. Avoid spraying water directly on the purifier. For stubborn fingerprints or smudges, a drop of isopropyl alcohol on a cloth works well—just don’t let it drip inside.

Check the sensor (usually near the base) and wipe it gently. A dirty sensor can cause false filter alerts.

Step 8: Reassemble the Purifier

Now that everything is dry and clean, it’s time to put it back together.

1. Insert the HEPA filter first. Make sure it sits flush in its housing. You should hear a soft click.
2. Slide the pre-filter back over it. It should fit snugly—no gaps.
3. Replace the outer cover. Line up the magnets or clips and press gently until it’s secure.

Double-check that everything is aligned. A misaligned filter can reduce performance and cause noise.

Step 9: Reset the Filter Indicator (If Applicable)

Many Dyson models have a filter life indicator on the screen or app. After cleaning, you’ll need to reset it.

Here’s how:

• On the device: Press and hold the “Filter” or “Reset” button for 3–5 seconds until the light changes.
• Via Dyson Link app: Open the app, go to “Settings,” and select “Reset Filter Life.”

This step is crucial. If you skip it, the purifier will keep showing a dirty filter alert, even after cleaning. Trust me, I’ve been there—it’s annoying.

Step 10: Run a Test Cycle

Plug the purifier back in and turn it on. Set it to low speed and let it run for 10–15 minutes.

Listen for unusual noises. Feel the airflow—it should be smooth and strong. If it’s weak or noisy, double-check the filter placement.

Smell the air. If there’s a musty odor, the filter might still be damp. Turn it off and let it dry longer.

Once it’s running smoothly, you’re done! You’ve just mastered how to clean Dyson air purifier filter in 2026.

Pro Tips & Common Mistakes to Avoid

After cleaning dozens of Dyson filters (mine and my friends’), I’ve learned a few things the hard way. Here are my top tips and warnings:

• Don’t wash the HEPA filter. I can’t stress this enough. The plastic casing is not waterproof. One rinse, and it’s toast.
• Don’t skip drying. Mold grows fast in warm, damp places. Your purifier is the perfect breeding ground.
• Clean the pre-filter every 1–2 months. If you have pets, kids, or live in a dusty area, do it monthly. Otherwise, every other month works.
• Replace the HEPA filter every 12 months. Even if it looks clean, the fibers degrade over time. Dyson’s app can track usage and alert you.
• Use only mild soap. Harsh detergents can break down the mesh and leave residue.
• Don’t use compressed air. It can damage the delicate pleats in the HEPA filter.
• Keep a cleaning log. I use a sticky note on the purifier: “Pre-filter cleaned: May 15.” It helps me stay on schedule.

Real-Life Example: My neighbor cleaned her pre-filter but forgot to dry it. A week later, her purifier started making a gurgling noise. She opened it and found a small patch of mold. She had to replace the filter and deep-clean the chamber. Don’t be that neighbor.

Also, in 2026, Dyson has introduced smart filters with embedded sensors. These track usage, humidity, and air quality. Cleaning them follows the same steps, but always check the app for specific alerts. Some models even tell you when the pre-filter needs cleaning—another reason why understanding how to clean Dyson air purifier filter in 2026 is essential for modern air care.

FAQs About How to Clean Dyson Air Purifier Filter in 2026

Let’s tackle the questions I get asked the most. These come from real users, just like you.

Can I wash the HEPA filter in my Dyson?

Nope. The HEPA filter is sealed in plastic and should never get wet. Washing it will ruin it and void any warranty. Only the outer pre-filter is washable. If your HEPA looks dirty or smells bad, it’s time to replace it—not clean it.

How often should I clean the pre-filter?

Every 1–2 months, depending on use. If you have pets, smoke, or live in a dusty area, clean it monthly. For light use, every other month works. Dyson’s app can help track this, but your nose is a good judge—if the air smells off, clean it.

Why is my Dyson purifier still showing a dirty filter after cleaning?

You probably forgot to reset the filter indicator. Most models have a reset button or app option. If you cleaned the pre-filter but the light is still on, that’s the issue. Also, if the HEPA filter is overdue for replacement, the purifier might still alert you—even after cleaning.

Can I use a hairdryer to dry the pre-filter faster?

Not recommended. High heat can warp or melt the mesh. If you must, use the lowest heat setting and keep it at least 12 inches away. Better yet, plan ahead and start drying the night before.

What if my filter is damaged or torn?

Replace it immediately. A torn pre-filter won’t trap particles effectively, and a damaged HEPA filter is useless. You can buy genuine Dyson filters from their website or authorized retailers. Avoid third-party knockoffs—they don’t meet the same standards.

Does cleaning the filter improve performance?

Absolutely. A clean filter allows better airflow, which means the purifier works more efficiently. It also reduces strain on the motor, which can extend the machine’s life. I’ve noticed a big difference in air quality after cleaning—my allergies are less intense, and my room feels fresher.

Are there any models with self-cleaning filters?

Not yet in 2026. But newer Dyson models have smart diagnostics that alert you when cleaning is due. Some even adjust fan speed based on filter condition. While not self-cleaning, these features make how to clean Dyson air purifier filter in 2026 easier to manage.

Final Thoughts

Cleaning your Dyson air purifier filter isn’t just a chore—it’s a small act of self-care. You’re not just maintaining a machine; you’re investing in your health and comfort. A clean filter means cleaner air, better performance, and fewer replacements.

Remember, the key to mastering how to clean Dyson air purifier filter in 2026 is consistency. Set a reminder on your phone, mark it on your calendar, or just tie it to another routine—like changing your sheets. Once a month, give your purifier a little love.

And don’t stress if you make a mistake. I’ve ruined a filter or two in my time. What matters is learning and doing better next time. Your Dyson is built to last, and with proper care, it will keep your air fresh for years.

So, go ahead—unplug, clean, dry, and reset. Then take a deep breath. That’s the sound (and smell) of fresh air, done right.
