Why This Matters / Understanding the Problem

Let’s be honest: air purifiers are amazing—until they’re not. You wake up with a stuffy nose, the fan sounds like it’s struggling, and suddenly, your Dyson air purifier isn’t doing its job. Sound familiar?

After living with a Dyson for over five years (and yes, I’ve had my fair share of filter fails), I learned the hard way that cleaning the filter isn’t just a “nice-to-do”—it’s essential. A clogged filter means poor airflow, reduced efficiency, and even potential damage to the motor. Plus, if you’re not cleaning it right, you could be wasting time or making things worse.

So, whether you’ve got a Dyson TP04, HP04, or the newer 2026 models, knowing how to clean filter on Dyson air purifier in 2026 easy steps is more important than ever. Dust, pet dander, pollen, and even cooking smoke can gunk up your filters faster than you think—especially if you live in a busy household or a city with high air pollution.

The good news? Cleaning your Dyson filter is not rocket science. With the right approach, you can keep your purifier running like new—without spending a dime on replacements. And in 2026, Dyson has made it even easier with updated filter designs and smart alerts. But you still need to know the right steps to avoid mistakes that could shorten your filter’s life or void your warranty.

In this guide, I’ll walk you through exactly how to clean filter on Dyson air purifier in 2026 easy steps—based on real testing, Dyson’s official recommendations, and my own trial-and-error (yes, I once used soapy water on a carbon filter—don’t do that).

What You Need

Before you start, let’s get your toolkit ready. The beauty of cleaning a Dyson air purifier filter is that you don’t need fancy tools. Just a few basics from around your home.

• Soft brush or microfiber cloth – For wiping down the exterior and removing surface dust.
• Vacuum with a brush attachment – A handheld vacuum works great for pulling dust off the pre-filter and housing.
• Dry, clean towel – For drying any moisture or wiping down parts.
• Compressed air (optional) – Helps blast out stubborn dust from crevices. Not required, but handy.
• Access to a sink or outdoor space – For rinsing the pre-filter (if your model has one).
• Your Dyson’s manual (or app) – To confirm filter types and cleaning instructions for your specific model.

Pro Tip: Always check your model number (usually on the bottom or back). Dyson has multiple filter types: HEPA, activated carbon, and some newer models use combined HEPA+Carbon or even antimicrobial filters. Cleaning methods vary slightly, so don’t assume one size fits all.

Also, keep in mind that only the pre-filter is washable on most Dyson models. The main HEPA and carbon filters are not meant to be soaked or scrubbed. More on that in the steps below.

And one more thing: never use bleach, harsh cleaners, or dish soap. These can damage the filter media and leave behind residues that affect air quality. Stick to water and air—your lungs (and your purifier) will thank you.

Now, with your supplies ready, let’s dive into how to clean filter on Dyson air purifier in 2026 easy steps—without breaking a sweat.

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

Step 1: Power Off and Unplug the Unit

First things first: safety. Always turn off your Dyson air purifier and unplug it from the wall. Even if it’s just sitting there quietly, you don’t want any surprises when you start taking it apart.

This is especially important on 2026 models, which have smart sensors and internal electronics. A sudden power surge or accidental button press could confuse the system or damage components.

Warning: Never open the filter compartment while the unit is running. Dyson’s safety lock (on newer models) may prevent access, but don’t force it. Patience is key.

Once it’s powered down, let it sit for a minute or two. This gives any residual charge a chance to dissipate and makes handling the internal parts safer.

Step 2: Remove the Outer Cover or Filter Housing

Dyson air purifiers have different designs, but most 2026 models use a twist-and-lift mechanism for the outer cover.

• On tower models (like TP07 or TP09), grip the top and twist the base slightly—usually counterclockwise.
• On fan-heater combos (like HP07 or HP09), there may be a button or latch on the side.
• Some newer models have a magnetic or snap-on cover—just pull gently at the seam.

Once the cover is off, you’ll see the filter housing. This is usually a cylindrical or rectangular unit that slides out.

For models like the Dyson Purifier Humidify+Cool (PH04), you may need to remove a front grill first. Use your fingers or a plastic pry tool (never metal) to avoid scratching.

Pro Tip: Take a quick photo of the filter setup before removing anything. This helps you remember how to reassemble it—especially if you’re cleaning multiple filters.

Step 3: Identify and Remove the Filters

Now comes the fun part: seeing what’s inside. Most Dyson air purifiers have at least two filters:

• Pre-filter (outer layer): Usually black or gray foam or mesh. Catches large particles like hair and dust.
• HEPA filter (middle layer): White, accordion-style paper. Captures fine particles like pollen and mold spores.
• Activated carbon filter (inner layer): Black, granular media. Absorbs odors, VOCs, and gases.

Some 2026 models use a combined HEPA+Carbon filter, which simplifies things. But you’ll still see a removable pre-filter.

To remove:

• Pull the pre-filter straight out. It’s usually held by a clip or just sits snugly.
• For the main filters, check for tabs or handles. Gently lift or slide them out. Don’t yank—these are delicate.

Important: Never remove the main HEPA or carbon filters for washing. They’re not designed to get wet. Only the pre-filter is washable. If you’re unsure, check your manual or the Dyson app.

Once removed, place the filters on a clean towel or paper towels. Avoid setting them on the floor—dust will stick instantly.

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

Ah, the star of the show: the pre-filter. This is the only part you can safely wash, and doing it right makes a huge difference in performance.

Here’s how to do it:

• Take the pre-filter to a sink or go outside with a hose.
• Rinse it under lukewarm water. Hot water can warp the foam or mesh.
• Use your fingers to gently squeeze and massage the filter. Think of it like kneading dough—work the water through to loosen trapped dust.
• Rinse until the water runs clear. This might take 1–2 minutes, depending on how dirty it is.

No scrubbing with brushes or sponges. The foam is porous and can tear easily.

Pro Tip: If your pre-filter is really grimy, let it soak in a bowl of cool water for 10–15 minutes. But never soak for hours—this can degrade the material over time.

After rinsing, gently shake off excess water. Then, place the pre-filter on a clean towel in a well-ventilated area to dry. Never put it in the dryer or near a heater. Let it air dry for at least 12–24 hours.

Yes, that’s a long time. But rushing this step risks mold growth or a damp filter that reduces airflow and harms your purifier’s efficiency.

Step 5: Clean the Main HEPA and Carbon Filters (Without Water)

Now, for the filters you can’t wash—but still need to clean. The HEPA and carbon filters are sealed units. Water will ruin them. Instead, use air and suction.

• Take the HEPA filter outside or to a garage. Use a vacuum with a brush attachment to gently vacuum both sides.
• Focus on the folds (pleats) where dust collects. Move slowly—don’t press too hard.
• For stubborn dust, use a can of compressed air. Hold it 6–8 inches away and blow from the clean side (the side that faces the room) toward the dirty side (facing the fan).
• Repeat for the carbon filter if it’s separate. If it’s combined, vacuum the entire surface.

Warning: Never use water, steam, or cleaning sprays on HEPA or carbon filters. This voids warranties and destroys the media. I once thought “a little water won’t hurt”—it did. The filter lost 40% efficiency after one rinse.

For 2026 models with smart filter tracking, Dyson’s app may show “filter life” percentage. Vacuuming helps extend that life, but don’t expect to reset it to 100%. The sensors detect physical degradation, not just surface dust.

Step 6: Clean the Filter Housing and Internal Components

While your filters are drying or being vacuumed, don’t neglect the inside of the purifier.

• Use a dry microfiber cloth to wipe down the filter housing and fan blades.
• For tight spaces, use a cotton swab or soft brush. A toothbrush (clean!) works great for crevices.
• If you see dust on the fan, use compressed air to blow it out—don’t touch the blades.
• For models with a humidifier (like PH04), wipe the water tank and mist outlet with a vinegar-water mix (1:1), then rinse thoroughly.

This step is often overlooked, but dust inside the unit can re-contaminate clean filters. Think of it like cleaning your fridge after throwing out expired food—you don’t want old smells lingering.

Step 7: Reassemble the Purifier

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

• Start by placing the main HEPA and carbon filters back into their slots. Make sure they’re seated properly—listen for a soft click or feel for a snug fit.
• Slide the pre-filter back in. It should fit snugly over the main filters. Some models have arrows or “TOP” labels—align them correctly.
• Reattach the outer cover. Twist or snap it into place. Don’t force it—if it’s not going on, double-check filter alignment.
• For models with a front grill, reattach it now.

Pro Tip: Before powering on, double-check that all filters are in place. A missing pre-filter can cause the purifier to overwork or trigger an error code.

Step 8: Power On and Reset the Filter Timer (If Needed)

Plug the unit back in and turn it on.

Most Dyson air purifiers have a filter life indicator. After cleaning, you may want to reset it—but only if you’ve replaced the filters. Cleaning doesn’t reset the timer, and resetting it prematurely could lead to a clogged system.

However, if you’ve replaced a filter, here’s how to reset:

• Hold the “Filter” or “Settings” button for 5–10 seconds until the light changes or the app confirms the reset.
• On newer 2026 models, open the Dyson app. Go to “Filter Management” and tap “Reset Filter Life.”

If you cleaned the filters (not replaced), don’t reset. The app will continue tracking actual usage.

Let the purifier run for 15–30 minutes. Listen for smooth airflow and check if the fan isn’t straining. If it sounds louder than usual, double-check the filter seating.

Pro Tips & Common Mistakes to Avoid

After years of cleaning Dyson filters—some successfully, some not—I’ve learned a few hard truths. Here are the pro tips and mistakes you should definitely avoid:

• Don’t wash HEPA or carbon filters. I said it before, but it’s worth repeating. Water ruins them. Stick to vacuuming and air.
• Never use compressed air indoors. It stirs up dust and can make your air worse. Take filters outside or to a garage.
• Don’t skip drying the pre-filter. A damp pre-filter is a mold magnet. Let it dry fully—no shortcuts.
• Check for tears or damage. If your pre-filter is frayed or the HEPA filter is cracked, replace it. A damaged filter is worse than no filter.
• Clean every 2–4 weeks in high-use areas. If you have pets, allergies, or live near traffic, clean more often. The Dyson app can help track usage.
• Use the Dyson app for reminders. Set up cleaning alerts. In 2026, Dyson’s AI can even detect when airflow drops and suggest cleaning.
• Don’t ignore the fan and vents. Dust inside the unit reduces efficiency. Clean them monthly.

Real-Life Example: My neighbor cleaned her pre-filter but forgot to vacuum the HEPA. After a month, the purifier sounded like a jet engine. A quick vacuum fixed it—but it could’ve been avoided with a full cleaning.

Another common mistake? Over-cleaning the pre-filter. Washing it too often (like weekly) can wear out the foam. Stick to every 2–4 weeks, or when it looks visibly dirty.

And if you’re wondering: “Can I use a hairdryer to speed up drying?” The answer is no. Heat damages the foam. Air drying is the only safe way.

FAQs About How to Clean Filter on Dyson Air Purifier in 2026 Easy Steps

Q: How often should I clean my Dyson air purifier filter?

A: It depends! For most homes, clean the pre-filter every 2–4 weeks and vacuum the main filters every 1–2 months. If you have pets, smoke, or live in a dusty area, do it weekly. The Dyson app (on 2026 models) gives personalized recommendations based on usage.

Q: Can I wash the HEPA filter in my Dyson?

A: No—and please don’t try. HEPA filters are made of paper-like media. Water will destroy their structure and reduce efficiency. Only vacuum them gently. If yours is beyond cleaning, replace it.

Q: Why is my Dyson purifier still loud after cleaning?

A: It could be several things: the pre-filter isn’t fully dry, the HEPA filter is damaged, or dust is still inside the fan housing. Check all components. Also, make sure filters are seated properly. A loose filter can vibrate and cause noise.

Q: Do I need to replace the pre-filter after cleaning it?

A: Not unless it’s damaged. The pre-filter is designed to be washed up to 50 times (Dyson’s estimate). But if it’s frayed, torn, or no longer holds its shape, replace it. A broken pre-filter lets dust bypass the main filters.

Q: Can I clean my Dyson filter with soap?

A: No. Soap leaves residues that can affect air quality and damage filter materials. Just use water for the pre-filter. For the rest, stick to vacuuming and air.

Q: How do I know when to replace the HEPA or carbon filter?

A: Dyson recommends replacing HEPA and carbon filters every 12 months (or 12,000 hours of use). The app will notify you. Signs include reduced airflow, persistent odors, or the filter looking gray and clogged. If you clean it and it still smells musty, it’s time to replace.

Q: Are 2026 Dyson filters different from older models?

A: Yes! Newer models often use combined HEPA+Carbon filters with antimicrobial coatings. They’re more efficient but still follow the same cleaning rules: vacuum only, no water. Always check your model’s manual or app for specifics.
