Why Changing Your Dyson Air Purifier Filter Matters

Imagine this: It’s a crisp winter morning, and you wake up to the soft hum of your Dyson air purifier doing its job. But as you take a deep breath, you notice something—your usual fresh, clean air feels a little stale. You’re not imagining things. That’s the moment you realize your filter might be due for a change.

Dyson air purifiers are fantastic at trapping dust, allergens, pet dander, and even microscopic pollutants. But over time, those filters get clogged. Like a sponge that’s absorbed too much, they lose efficiency. A dirty filter doesn’t just reduce performance—it can actually release trapped particles back into your air, making things worse instead of better. That’s why knowing how to change Dyson air purifier filter isn’t just a maintenance task; it’s essential for keeping your home truly clean and healthy.

Whether you’ve had your Dyson for a year or just moved into a home with one, this guide will walk you through the process step by step. No confusing jargon. No vague instructions. Just simple, practical advice—like a friend showing you how to do it in real time. And don’t worry: even if you’ve never touched a filter before, you’ve got this.

When to Change Your Dyson Air Purifier Filter (And How to Know)

Let’s get real: no one wants to change a filter too early and waste money, or too late and breathe dirty air. So how do you know when it’s time? Dyson makes it easier than most brands, but there are still a few things to watch for.

Check the Built-in Filter Life Indicator

Most Dyson air purifiers—like the TP07, TP09, HP07, and BP01—come with a built-in filter life indicator. This is your best friend. When you turn on the purifier, the display (or app) shows how much life your filter has left. It usually starts at 100% and drops over time.

• 10–20% remaining: Start planning your filter change. Order a new one if you don’t already have it.
• 5% or less: The machine may flash a warning or send a notification via the Dyson app. Time to act.
• 0%: The purifier might stop working or run at reduced power. Don’t ignore this.

Pro tip: The indicator is based on usage and room conditions. If you run your purifier 24/7 in a dusty or smoky environment, the filter will wear out faster than the average 12-month lifespan.

Look for Physical Signs

Even if the indicator says you’re fine, your eyes and nose can tell you more. Here’s what to watch for:

• Visible dirt or discoloration: Open the purifier and check the filter. If it’s gray, brown, or covered in dust, it’s time.
• Reduced airflow: The purifier sounds louder or the breeze feels weaker? A clogged filter restricts airflow.
• Unusual odors: If your purifier starts smelling musty, moldy, or like stale air, the activated carbon filter may be saturated.
• Increased allergy symptoms: Sneezing, congestion, or itchy eyes when the purifier is on? That’s a red flag.

I once ignored a slightly musty smell for weeks. Then one day, I opened the purifier and found the filter looked like a dust bunny convention. Lesson learned: trust your senses.

How Often Should You Change It?

Dyson recommends replacing the filter every 12 months with normal use (about 12 hours per day). But your mileage may vary:

• High-usage homes (24/7 operation, pets, smokers): Every 6–8 months
• Allergy-prone households: Every 9–12 months, but check monthly
• Low-usage homes (a few hours a day): Up to 18 months, but still monitor

The key is not to rely solely on the calendar. Use the indicator, your senses, and your environment to decide.

Types of Dyson Air Purifier Filters (Know What You’re Replacing)

Not all Dyson filters are the same. Using the wrong one—or a knockoff—can damage your machine or reduce performance. Let’s break down what you need to know.

HEPA + Activated Carbon Combo Filter

This is the most common filter type in Dyson purifiers. It’s a single unit with two parts:

• HEPA layer: Captures 99.97% of particles as small as 0.3 microns (dust, pollen, mold, pet dander).
• Activated carbon layer: Absorbs gases, odors, and VOCs (like cooking smells or cleaning fumes).

Models that use it: TP07, TP09, HP07, HP09, BP01, and most newer models. This is the one you’ll most likely be replacing.

Tip: The HEPA layer is usually white or off-white. The carbon layer is black or dark gray. If the white part looks dirty or the black part smells bad, both parts need replacing.

Pre-Filter (Some Models)

A few Dyson models—like the AM11 and some older TP01 variants—have a separate pre-filter. This is a mesh screen that catches large particles like hair and dust before they reach the main filter.

• Clean every 1–2 months with a vacuum or soft brush.
• Replace every 1–2 years, depending on use.

It’s not the main event, but keeping it clean extends the life of your HEPA/carbon filter. Think of it like a bouncer at a club—it keeps the riffraff out so the VIP (main filter) can do its job.

Specialty Filters (Rare but Important)

Dyson occasionally releases models with specialized filters. For example:

• Formaldehyde-specific carbon layer: In models like the TP09, designed to break down formaldehyde from furniture or paint.
• Allergy+ filters: Extra-thick HEPA layers for severe allergy sufferers.

Always check your model number before buying. You can find it on the bottom of the purifier or in the Dyson app. Never assume a filter fits just because it looks similar.

OEM vs. Third-Party Filters: What’s the Difference?

You’ll see cheaper “compatible” filters online. They might look the same, but there’s a catch:

• OEM (Original Equipment Manufacturer) filters: Made by Dyson. Guaranteed fit, performance, and safety. Slightly more expensive (~$50–$70).
• Third-party filters: Often lower quality. May not seal properly, reducing efficiency. Some even release particles back into the air. Riskier, but cheaper (~$20–$30).

I tried a third-party filter once to save money. Within a week, my purifier started beeping and the app said “filter not recognized.” I had to buy an OEM one anyway. Lesson: stick with OEM. Your health and machine are worth the extra cost.

How to Change Dyson Air Purifier Filter: Step-by-Step (2026 Guide)

Ready to swap that old filter? Don’t worry—it’s easier than changing a lightbulb. I’ve done this on three different Dyson models, and the process is nearly identical. Here’s how to do it in 2026, updated for the latest models.

Step 1: Turn Off and Unplug the Purifier

Safety first! Even though the filter isn’t electrical, you don’t want the fan running while you’re inside the machine. Unplug it from the wall and wait 30 seconds. This also gives the motor time to cool down.

Pro tip: Do this during a quiet time—like morning or evening—so you’re not interrupting your air cleaning.

Step 2: Open the Filter Housing

This is where models differ slightly. Here’s how to open the most common ones:

• TP07, TP09, HP07, HP09 (Tower & Hot+Cool models):
  • Place the purifier on a flat surface, base down.
  • Press the release button on the side of the lower half (usually near the base).
  • Gently pull the lower housing apart from the upper half. It should split vertically.
  • You’ll see the filter inside—usually in a removable cartridge.
• BP01 (Bladeless Desk Fan):
  • Turn the purifier upside down.
  • Locate the small locking tab on the bottom.
  • Press and hold it while twisting the base counterclockwise.
  • Lift off the base to reveal the filter.

If it feels stuck, don’t force it. Double-check for a release button or tab. Most models have a soft “click” when it opens.

Step 3: Remove the Old Filter

Once the housing is open, you’ll see the filter cartridge. It’s usually held in place by small clips or friction.

• Gently pull the cartridge straight out. Don’t twist or yank.
• If there’s a pre-filter, remove it first (it’s usually on top).
• Hold the filter over a trash can and tap it lightly to shake loose dust. Avoid inhaling—wear a mask if you’re sensitive.

Real talk: This part can be gross. My first filter change looked like I was holding a dust bomb. That’s how well it works!

Step 4: Insert the New Filter

Now for the easy part. Take your new OEM filter and:

• Check the arrow or “this side up” label. It must face the correct direction (usually toward the fan).
• Slide the filter into the housing until it clicks or seats firmly.
• If there’s a pre-filter, place it on top of the main filter (if applicable).

Make sure it’s snug. A loose filter can let unfiltered air slip by, reducing efficiency.

Step 5: Reassemble the Purifier

Reverse the opening steps:

• For tower models: Align the upper and lower halves and press together until it clicks.
• For BP01: Place the base back on, twist clockwise, and press the tab to lock.

Double-check that it’s fully closed. A gap means it’s not sealed properly.

Step 6: Reset the Filter Life Indicator

This is crucial! Otherwise, your purifier will keep showing the old filter’s life.

• Via the Dyson app: Open the app, go to your purifier, and tap “Reset Filter Life.”
• Manually (if no app): Turn on the purifier, press and hold the “Oscillation” or “Filter” button for 5–10 seconds until the indicator resets to 100%.

Note: Some 2026 models auto-detect new filters. But it’s safer to reset manually.

Step 7: Test and Monitor

Plug in the purifier and turn it on. Listen for normal operation—no weird noises or vibrations. Check the app or display to confirm the filter life shows 100%.

Run it for 15 minutes. You should notice:

• Stronger airflow
• No odors
• Reduced allergy symptoms (if applicable)

If anything feels off, double-check the filter placement and seal.

Tips to Extend Filter Life (Save Money & Breathe Better)

Changing filters is simple, but you can make them last longer. Here’s how to get the most value from each one.

Clean the Pre-Filter Regularly

If your model has a pre-filter, clean it every 4–6 weeks. Use a soft brush or vacuum with a brush attachment. This removes large particles before they clog the main filter.

Example: My cat sheds like crazy. I clean the pre-filter every 3 weeks, and my main filter lasts 14 months instead of 12.

Vacuum Around the Air Intake

Dyson purifiers pull air from the base. If the intake is covered in dust, the filter works harder. Every 2–3 weeks, vacuum the area around the purifier and wipe the intake vents with a dry cloth.

Use in the Right Environment

• Avoid extreme dust: Don’t place near a woodworking shop or open window during a storm.
• Reduce smoke exposure: If you cook with oil or grill, use a range hood to cut down on smoke hitting the purifier.
• Keep pets away: Long-haired pets love to sit near purifiers. Their fur can clog filters faster.

Run Smartly (Use Auto Mode)

Most Dyson purifiers have an Auto Mode that adjusts fan speed based on air quality. It runs slower when air is clean, reducing wear on the filter. Enable this in the app or on the machine.

Store Spare Filters Properly

If you buy an extra filter, keep it sealed in the original packaging, in a cool, dry place. Avoid humidity (like a bathroom) or extreme heat (like a garage). A damaged seal can ruin the filter before you use it.

Common Mistakes & How to Avoid Them

Even with good intentions, people slip up. Here are the most common mistakes—and how to avoid them.

Forgetting to Reset the Filter Indicator

You change the filter, but the display still shows “5% life left.” This is the #1 mistake. The purifier thinks the old filter is still in. Always reset the indicator after replacing the filter.

Using the Wrong Filter Model

TP07 and TP09 filters look similar but aren’t interchangeable. Check your model number before buying. A quick Google search of “[your model] filter” helps. When in doubt, buy from Dyson’s official store.

Not Sealing the Housing Properly

If the housing isn’t fully closed, air can bypass the filter. This defeats the purpose. After reassembling, run your hand around the seam to feel for gaps. Listen for a faint “whoosh” of unfiltered air.

Changing Too Early (or Too Late)

Changing too early wastes money. Changing too late risks poor air quality. Use the indicator, your senses, and your environment—not just the calendar.

Ignoring the Dyson App

The app gives real-time air quality data and filter alerts. Set up notifications so you never miss a change. It’s like having a personal air quality assistant.
