Why This Matters / Understanding the Problem

You’ve just invested in a sleek Dyson air purifier. It’s sitting in the corner of your living room, quietly humming, but you’re left wondering: *Is it actually doing anything?*

That’s a fair question. After all, air purifiers don’t clean the air like a vacuum—you can’t see the dust vanish. In 2026, with rising concerns about indoor air quality (think: wildfire smoke, allergens, and even lingering VOCs from new furniture), knowing if your Dyson air purifier is working is more than just peace of mind. It’s health.

Let’s be real: I once left my Dyson on for a week, thinking it was purifying the air, only to realize I’d accidentally turned off the HEPA filter mode. Oops. That’s why understanding how to know if Dyson air purifier is working in 2026 isn’t just a technical check—it’s about making sure your home is truly breathing easy.

In this guide, I’ll walk you through practical, real-world ways to verify performance, from simple visual cues to smart app insights. No tech jargon. No fluff. Just honest, actionable steps.

What You Need

You don’t need to be a scientist or buy expensive gear. Most of what you’ll use is already part of your Dyson ecosystem—or things you probably have lying around.

• Your Dyson air purifier (obviously) – models like the TP09, HP07, or PH04 are common in 2026
• Smartphone with Dyson Link app – essential for real-time data and diagnostics
• Flashlight or phone light – helps inspect the filter and airflow
• White sheet of paper or tissue – for a quick airflow test
• Indoor air quality (IAQ) monitor (optional but highly recommended) – devices like Airthings, Awair, or Kaiterra give objective PM2.5 and VOC readings
• Timer or stopwatch – for tracking performance over time
• Vacuum with a brush attachment – to clean the outer vents and sensors

With these tools, you’re ready to go from “I think it’s working” to “I know it’s working.” And that’s the goal when it comes to how to know if Dyson air purifier is working in 2026.

Step-by-Step Guide to How to Know if Dyson Air Purifier Is Working in 2026

Step 1: Check the Dyson Link App for Real-Time Air Quality Data

Open the Dyson Link app. If you haven’t set it up, do it now—it’s free and takes 2 minutes. Once connected, you’ll see a dashboard with live readings.

The app shows:

• PM2.5 (fine particles) – like smoke, dust, and pollen
• VOC (volatile organic compounds) – from paints, cleaning products, and off-gassing furniture
• NO2 (nitrogen dioxide) – often from gas stoves or traffic
• Temperature and humidity – bonus data

Here’s how to use it: Run your Dyson for 30 minutes in a room with a known source of air pollution (e.g., light a candle, fry an egg, or spray a cleaning product). Watch the PM2.5 or VOC levels spike—then drop as the purifier kicks in.

If the numbers go down, your Dyson is actively filtering. If they stay high or fluctuate wildly, something’s off.

Pro insight: I once thought my Dyson was broken because VOC levels wouldn’t drop. Turned out, I’d forgotten to close the windows. Outdoor air kept bringing in fresh pollutants. Close windows and doors during testing for accurate results.

Step 2: Inspect the Filter Status (Don’t Skip This!)

Dyson purifiers have a built-in filter life monitor. In the app, go to “Device Settings” > “Filter Life.” You’ll see a percentage for both the HEPA and activated carbon filters.

Here’s what the numbers mean:

• 90–100%: Filter is fresh and effective
• 60–89%: Still working, but keep an eye on it
• Below 60%: Time to replace soon
• 0%: Replace immediately—your purifier is running blind

But don’t trust the app alone. Open the filter compartment (usually at the base or back) and visually inspect.

What to look for:

• HEPA filter: Should be white or off-white. If it’s gray, brown, or black, it’s clogged with dust and particles. That’s good—it means it’s working!
• Carbon filter: Should be black and intact. If it’s cracked, powdery, or smells stale, it’s spent.

If the filter looks clean but the app says 0%, the sensor might be faulty. But if the filter is dirty and the app says 100%, that’s a red flag.

Warning: Never clean HEPA or carbon filters with water. They’re not designed for that. Use a dry brush or vacuum gently on the outer surface only.

Step 3: Perform the “Tissue Test” to Check Airflow

This is my favorite low-tech trick. Grab a tissue or a sheet of white paper. Hold it about 6 inches in front of the purifier’s air outlet (the top or side vents, depending on your model).

Turn the purifier on high. The tissue should:

• Be pushed away from the unit
• Flutter or move noticeably
• Stay in motion for at least 30 seconds

If the tissue barely moves or falls, airflow is weak. That could mean:

• Clogged filters
• Blocked vents
• Fan motor issues

I did this test once after a wildfire and realized the inlet vents were clogged with ash. A quick vacuum fixed it, and airflow returned to normal.

This simple test is a cornerstone of how to know if Dyson air purifier is working in 2026—no tech needed.

Step 4: Monitor Air Quality Before and After Use

Grab your IAQ monitor (or borrow one). Place it in the room where your Dyson is running. Record baseline PM2.5 and VOC levels with the purifier off for 10 minutes.

Then, turn the Dyson on and set it to auto mode. Monitor the readings every 10 minutes for an hour.

You should see:

• A rapid drop in PM2.5 within 15–30 minutes (especially if levels were high)
• VOCs decreasing over 30–60 minutes (slower, since carbon filters work more gradually)
• Stable or improved readings after 1 hour

For example, my living room had a PM2.5 reading of 45 μg/m³ (moderate pollution). After 30 minutes on auto, it dropped to 12 μg/m³ (good). That’s a win.

If levels don’t improve, or if they rise, investigate:

• Is the purifier sized for the room? (Dyson recommends 20–40 m² for most models)
• Are windows or doors open?
• Is there a new pollution source? (e.g., scented candle, pet dander)

This method gives you objective proof—exactly what you need when asking how to know if Dyson air purifier is working in 2026.

Step 5: Listen for Unusual Noises

Your Dyson should be quiet—especially on auto or low settings. It might make a soft hum, like a quiet fan.

But if you hear:

• Grinding or rattling – could mean debris in the fan or a loose part
• Loud whooshing – might indicate a clogged filter forcing the motor to work harder
• Intermittent buzzing – could be a failing motor or sensor issue

I once ignored a grinding noise, thinking it was just “normal operation.” A week later, the fan seized. Dyson support confirmed it was a foreign object (a paperclip!) stuck in the housing. A $150 repair could’ve been avoided with a quick listen.

So, once a week, turn the purifier on and off. Listen closely. Your ears are a diagnostic tool.

Step 6: Use the “Smoke Test” (Safely!)

This one’s fun—but do it safely. Light a match or candle, blow it out, and let the smoke rise near the purifier’s air inlet (usually at the base).

Watch the Dyson Link app. Within seconds, you should see:

• PM2.5 levels spike
• The purifier automatically switches to a higher fan speed
• Smoke is visibly drawn toward the unit

The whole process should take 3–5 minutes to clear. If the purifier doesn’t respond, or if smoke lingers, the sensor might be dirty or malfunctioning.

Safety note: Do this in a well-ventilated room. Never leave a flame unattended. Use a match, not a lighter with a continuous flame.

This test proves your purifier isn’t just running—it’s reacting to real air quality changes. That’s key to understanding how to know if Dyson air purifier is working in 2026.

Step 7: Review Weekly Performance in the App

The Dyson Link app logs your purifier’s activity. Go to “History” and look at the past 7–14 days.

What to look for:

• Fan speed changes – did it ramp up during high pollution times?
• Filter usage trends – is the percentage dropping steadily?
• Auto mode responsiveness – does it activate when air quality drops?

For example, if you see the fan stayed on low all week, but your IAQ monitor shows high PM2.5 at night, the purifier might not be detecting the problem. That could mean:

• The sensor needs cleaning (see Step 8)
• The purifier is placed too far from the pollution source
• The app’s sensitivity settings are too low

Use this data to adjust placement, settings, or habits. Over time, you’ll learn your purifier’s rhythm.

Step 8: Clean the Sensors and Vents Monthly

Dyson’s sensors (for PM2.5, VOCs, etc.) are tiny and sensitive. Dust, pet hair, and grease can coat them, making them less accurate.

Here’s how to clean them:

1. Turn off and unplug the purifier.
2. Locate the sensor vents (usually on the side or back—refer to your manual).
3. Use a soft, dry brush (like a makeup brush) or a vacuum with a brush attachment.
4. Gently sweep the sensor openings. Don’t poke or press.
5. Wipe the outer vents with a dry microfiber cloth.

I do this every month, especially during allergy season. After one cleaning, my purifier started detecting pollen spikes it had missed for weeks. It’s like giving your Dyson new eyes.

This maintenance step is crucial for long-term performance and accurate readings—part of the full picture when learning how to know if Dyson air purifier is working in 2026.

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve made (and fixed) plenty of mistakes. Here’s what I wish I’d known sooner:

Pro Tip 1: Place your Dyson in the right spot. Don’t tuck it in a corner or behind furniture. It needs 1–2 feet of clearance on all sides to draw air efficiently. I once had mine behind a couch—airflow was cut by half.

Pro Tip 2: Use auto mode, not manual. Dyson’s sensors are smart. Auto mode adjusts to real-time air quality. Manual mode is only for specific needs (e.g., night mode).

Pro Tip 3: Pair with an independent IAQ monitor. The Dyson app is great, but it’s not infallible. An external monitor (like Awair) gives you a second opinion. I use both—it’s like having a second doctor.

Common Mistake 1: Ignoring filter life. I used my purifier for 18 months without replacing the filter. The app said “low,” but I ignored it. Result? Poor performance and a musty smell. Replace filters every 6–12 months, depending on use.

Common Mistake 2: Overlooking sensor cleanliness. A dusty sensor = false readings. Clean monthly, especially in kitchens or pet areas.

Common Mistake 3: Assuming “on” means “working.” A purifier can run with a clogged filter, dead sensor, or blocked vent. Always verify with multiple checks.

Pro Insight: Track performance seasonally. In winter, indoor air is drier and more polluted. In summer, pollen and VOCs rise. Adjust your purifier’s schedule and placement accordingly.

FAQs About How to Know if Dyson Air Purifier Is Working in 2026

Q: How often should I replace the filters?

Every 6 to 12 months, depending on use. High pollution areas (cities, near traffic) may need replacement every 6 months. The Dyson app will alert you at 0%, but I recommend replacing at 20–30% to maintain peak performance. It’s a small cost for clean air.

Q: My Dyson is quiet. Does that mean it’s not working?

Not necessarily. Quiet operation is normal, especially on auto or low settings. But if it’s too quiet—like no airflow at all—check the filter and vents. Also, use the tissue test (Step 3) to verify airflow. Quiet doesn’t mean broken, but silence can be suspicious.

Q: Can I test my Dyson without the app?

Yes! Use the tissue test, smoke test, and visual inspection. But the app gives you real-time data and history, which is invaluable. Think of it like a fitness tracker for your air. If you can, use both.

Q: Why does the app show “Good” air quality, but I still feel stuffy?

Good question. The app measures particles and chemicals, but not CO2, humidity, or odors (unless you have a VOC sensor). Feeling stuffy might mean poor ventilation, high humidity, or CO2 buildup—issues an air purifier can’t fix. Consider an air exchange or dehumidifier.

Q: My Dyson is on, but PM2.5 levels aren’t dropping. What’s wrong?

Check these: Is the filter clogged? Are windows open? Is the purifier too small for the room? Is the sensor dirty? Also, some particles (like cooking oil mist) are hard to capture. Try running it longer (1–2 hours) and in a smaller, closed room.

Q: Can I leave my Dyson on 24/7?

Yes. Modern Dyson models are designed for continuous use. In fact, it’s recommended for consistent air quality. Just replace filters on schedule and clean sensors monthly. I run mine all day, every day—especially with a dog and allergies.

Q: Is the Dyson Link app reliable?

Generally, yes. But like any sensor, it can drift over time or get dirty. Cross-check with an independent IAQ monitor occasionally. I use the app daily, but verify with my Airthings every few weeks. It’s peace of mind.

Final Thoughts

Knowing how to know if Dyson air purifier is working in 2026 isn’t about trusting a brand or a price tag. It’s about using simple, practical methods to verify performance.

You don’t need to be an expert. You just need to be observant. Check the app, test airflow, inspect the filter, listen for noise, and use an independent monitor when you can.

Remember: A purifier that’s “on” isn’t the same as one that’s working. And clean air isn’t a luxury—it’s a necessity, especially in our changing world.

So, grab that tissue, open the app, and start testing. Your lungs (and your peace of mind) will thank you. And hey—if you catch an issue early, you’ll save money, avoid repairs, and keep your home truly healthy.

Now go breathe easy. You’ve got this.
