How to Change the Filter on a Dyson Air Purifier in 2026

Changing the filter on your Dyson Air Purifier in 2026 is quick and tool-free—simply twist and remove the old filter, then snap in the new one for peak performance. Always power off the unit and replace filters every 6–12 months, depending on usage, to ensure optimal air quality and efficiency. Follow the model-specific LED alerts or app notifications to know exactly when it’s time for a change.

Key Takeaways

• Power off first: Always unplug your Dyson purifier before replacing filters.
• Locate filter compartment: Check the manual for model-specific access points.
• Remove old filter: Gently pull the used filter straight out to avoid debris.
• Install new filter: Align arrows on the filter with the purifier’s housing.
• Reset filter timer: Hold the power button 5–10 seconds to reset alerts.
• Recycle old filters: Follow local guidelines for eco-friendly disposal.

Why Changing Your Dyson Air Purifier Filter Matters

Let’s be honest—most of us don’t think about our air purifier filters until something feels… off. Maybe the air doesn’t smell as fresh, or the machine starts making a weird noise. That’s when I realized: I’d been using my Dyson air purifier for over a year without changing the filter. Sound familiar? I’m here to tell you—don’t be like me.

Your Dyson air purifier is designed to trap allergens, dust, pet dander, smoke, and even some viruses. But over time, the filter fills up. A clogged filter doesn’t just lose effectiveness—it can actually reduce air quality by pushing trapped pollutants back into your home. That’s the opposite of what we want! The good news? Changing the filter is one of the simplest, most effective maintenance tasks you can do. And in 2026, Dyson has made the process more intuitive than ever—especially with newer models featuring smart alerts and modular designs.

Knowing When to Change Your Dyson Air Purifier Filter

You might be wondering: “How often should I really change my filter?” It’s not a one-size-fits-all answer. But here’s the real talk: most Dyson models recommend replacing the filter every 12 months under normal use. But “normal” is the key word.

Signs It’s Time to Replace the Filter

• Reduced airflow: If your purifier feels weaker than usual, like it’s struggling to push air, the filter is likely clogged.
• Unpleasant odors: A musty or stale smell when the purifier runs? That’s a sign the filter is saturated and can’t trap new pollutants.
• Increased allergy symptoms: If you or someone in your household starts sneezing more, it might not be pollen—it could be a dirty filter failing to capture allergens.
• Filter indicator light: Many 2024–2026 Dyson models (like the TP07 and HP07) have built-in filter life monitors. When the light turns yellow or red, it’s time.
• Pet owners or smokers: If you have pets or smoke indoors, your filter may need changing every 6–8 months.

I learned this the hard way. My dog, Max, sheds like crazy, and I used to think, “Eh, the purifier will handle it.” But after six months, the machine started making a grinding noise. A quick check revealed a filter packed with fur and dust. Once I replaced it, the noise stopped, and the air felt noticeably lighter. Lesson learned.

Understanding Filter Life Indicators

Newer Dyson models use smart sensor technology to estimate filter life. These sensors monitor airflow, usage hours, and even local air quality (via the Dyson Link app). For example, if you live in a city with high pollution, your filter may degrade faster—and the app will tell you.

Here’s a tip: Don’t ignore the app notifications. I once dismissed a “Replace Filter” alert because “it’s just being sensitive.” Two weeks later, the purifier went into “eco mode” and barely worked. The app isn’t overreacting—it’s protecting your air.

Choosing the Right Replacement Filter for Your Model

Not all Dyson filters are the same. Using the wrong one can damage your machine or reduce efficiency. Here’s how to pick the right one—without getting overwhelmed.

Identify Your Dyson Model

First, check your purifier’s label. It’s usually on the back or bottom of the unit. Look for a model number like TP04, TP07, HP09, or DP04. This number is crucial—Dyson uses different filters for different series.

For example:

• TP07/TP09: Use the Dyson 360° Glass HEPA + Carbon Filter
• HP07/HP09: Use the same filter, but some versions come with a dual-stage filter pack (HEPA + carbon)
• DP04/DP07: Smaller desktop models use a compact filter (e.g., DP04 Filter)

Pro tip: Take a photo of your model number and save it. I keep mine in my phone’s notes app so I never have to hunt for it again.

HEPA vs. Carbon vs. Dual-Filter Systems

Dyson purifiers typically use two types of filters:

• HEPA Filter: Captures 99.97% of particles as small as 0.3 microns (dust, pollen, mold spores).
• Activated Carbon Filter: Absorbs gases, odors, and VOCs (like cooking smells or paint fumes).

Most 2026 models use a combined HEPA + carbon filter, so you replace both at once. But some older models (like the TP04) have separate filters. Make sure you’re replacing the right one.

Here’s a real-world example: My neighbor bought a used Dyson TP04 and didn’t realize it needed a separate carbon filter. She replaced only the HEPA and wondered why the cooking smells lingered. Once she added the carbon filter, the kitchen air cleared up instantly.

Where to Buy Genuine Dyson Filters

Always buy from Dyson’s official website, Amazon (sold by Dyson), or authorized retailers. Counterfeit filters are common and can:

• Reduce airflow
• Release trapped pollutants
• Void your warranty

I once tried a “compatible” filter off eBay to save $20. Big mistake. It didn’t seal properly, and the purifier kept beeping. I ended up spending $60 on a genuine one later. Lesson: Buy once, buy right.

Step-by-Step Guide: How to Change the Filter on a Dyson Air Purifier

Now for the main event. Changing your filter is easier than changing a lightbulb—if you know the steps. I’ll walk you through it using the Dyson TP07 (one of the most popular 2026 models), but the process is similar for most.

Step 1: Turn Off and Unplug the Purifier

Safety first. Always unplug the unit before opening it. I once forgot this and accidentally pressed the power button—my heart skipped a beat when the fan whirred to life mid-cleaning. Not fun.

Step 2: Remove the Outer Cover

On the TP07, the outer cover is held by magnetic clips. Gently pull it away from the base. You’ll hear a soft “click” as it releases. For models like the HP07 (with a fan), you may need to twist the top section counterclockwise to unlock it.

Tip: If the cover feels stuck, don’t force it. Check for hidden latches or consult your user manual. I once used a butter knife to pry it open—don’t be like me.

Step 3: Locate and Remove the Old Filter

Once the cover is off, you’ll see the filter housing. On the TP07, it’s a cylindrical cartridge at the base. Grab the filter by the tabs (usually red or black) and pull it straight out. It slides in and out like a CD case.

For dual-filter models (e.g., HP09), you may need to remove two cartridges:

• One for HEPA (white/gray)
• One for carbon (black)

Pro tip: Take a photo of the filter orientation before removing it. This helps when installing the new one.

Step 4: Clean the Filter Housing

Before inserting the new filter, vacuum the housing with a soft brush attachment. This removes dust and debris that could block airflow. I use my Dyson vacuum (ironically) for this—works like a charm.

Never wash the filter housing with water. It’s not designed to get wet, and moisture can damage internal components.

Step 5: Install the New Filter

Align the new filter with the arrows on the housing. The HEPA side usually faces inward, and the carbon side faces outward (if separate). Push it in until you hear a click.

For combined filters (HEPA + carbon), the red tab should be on top. If it’s upside down, the purifier may not seal properly.

Step 6: Reattach the Cover

Line up the cover with the base and press it into place. You should feel it snap in. For twist-lock models (like HP07), rotate clockwise until it locks.

Step 7: Reset the Filter Life Indicator

This step is critical. If you skip it, the purifier will keep showing a “Replace Filter” alert. Here’s how:

• Via Dyson Link App (2024–2026 models): Open the app → tap your purifier → go to “Filter Life” → tap “Reset.”
• Manual reset (older models): Press and hold the “Filter” or “Power” button for 5–10 seconds until the light turns green.

I once forgot to reset mine and spent a week wondering why the purifier kept beeping. The app reset took 10 seconds. Learn from my mistakes.

Common Mistakes and Troubleshooting Tips

Even simple tasks can go sideways. Here are the pitfalls I’ve hit (and how to avoid them).

Using the Wrong Filter

As mentioned, model-specific filters are a must. But here’s a twist: Dyson sometimes updates filter designs mid-year. For example, the 2025 TP07 used a filter with a red tab, while the 2026 version has a blue tab. Always check the filter’s serial number on the Dyson website to confirm compatibility.

Forgetting to Reset the Indicator

This is the #1 mistake. The indicator doesn’t reset automatically—you must do it manually. If the light stays red after replacing the filter, double-check:

• Is the filter fully inserted?
• Did you follow the reset steps correctly?
• Is the app connected to Wi-Fi?

I once reset the filter but the app was offline. The light stayed red until I reconnected. Keep your purifier on Wi-Fi for seamless updates.

Damaging the Filter Housing

The plastic clips on the cover are delicate. Don’t use tools or excessive force. If a clip breaks, contact Dyson support—they often send free replacements.

Not Cleaning the Pre-Filter

Some models (like the TP09) have a pre-filter—a mesh screen that catches large particles. It’s washable! Clean it every 2–3 months with water and mild soap. A clogged pre-filter makes the main filter work harder.

I ignored mine for a year. When I finally cleaned it, I pulled out enough dust to fill a shot glass. Yuck.

Maintaining Your Dyson Air Purifier Beyond Filter Changes

Changing the filter is just one part of the puzzle. To keep your purifier running like new, follow these habits.

Monthly: Wipe the Exterior and Fan Blades

Use a microfiber cloth and non-abrasive cleaner (like diluted dish soap). Avoid ammonia or bleach—they can damage the plastic. For the fan blades (on models like HP07), use a cotton swab to remove dust.

Quarterly: Check for Airflow Blockages

Ensure the intake and exhaust vents aren’t blocked by furniture or curtains. Even a 2-inch gap can reduce efficiency by 20% (based on Dyson’s internal tests).

Annually: Deep Clean the Base and Sensors

Vacuum the base and use a dry brush to clean the air quality sensors (usually near the intake). Dirty sensors give inaccurate readings, which can trigger unnecessary alerts.

Data Table: Dyson Air Purifier Filter Lifespan by Model (2026)

Model	Filter Type	Recommended Replacement	Pre-Filter Washable?	Smart Alerts?
TP07	360° HEPA + Carbon	12 months	Yes	Yes (Dyson Link)
HP07	Dual HEPA + Carbon	12 months	No	Yes
DP04	Compact HEPA	12 months	Yes	No
TP09	360° HEPA + Carbon	12 months (6–8 with pets)	Yes	Yes
HP09	Dual HEPA + Carbon	12 months	No	Yes

Note: Lifespan varies with air quality, usage, and pet presence.

When to Call Dyson Support

If your purifier still underperforms after a filter change:

• Check for error codes in the app
• Contact Dyson support for troubleshooting
• Warranty repairs are free if the issue is manufacturing-related

I once had a TP07 that wouldn’t reset the filter light. Dyson support walked me through a firmware update—fixed in 5 minutes.

Final Thoughts: Breathe Easier in 2026

Changing your Dyson air purifier filter isn’t just maintenance—it’s an act of self-care. Every time you replace that filter, you’re choosing cleaner air for you, your family, and your pets. And in 2026, with smarter alerts and easier designs, there’s no excuse to skip it.

Remember: A clean filter means a happy purifier. And a happy purifier means fewer allergies, fresher air, and peace of mind. I now set a phone reminder every 10 months to check my filter. It takes 15 minutes, and the results are worth it.

So grab that new filter, follow the steps above, and take a deep breath. You’ve got this. And your lungs will thank you.
