How to Clean Dyson Air Purifier Hot Cold in 2026

Key Takeaways

• Turn off and unplug the purifier before cleaning for safety.
• Wipe the exterior with a dry or slightly damp microfiber cloth.
• Clean the filter regularly as per Dyson’s schedule to maintain efficiency.
• Use compressed air to remove dust from vents and internal grilles.
• Never rinse filters with water unless they’re labeled washable.
• Reassemble carefully to ensure proper airflow and heating function.

Why This Matters / Understanding the Problem

Let’s be real—your Dyson Air Purifier Hot+Cold isn’t just a fancy gadget. It’s your home’s first line of defense against dust, allergens, pet dander, and even seasonal pollen. But here’s the thing: if you don’t clean it regularly, it starts working against you. A clogged filter or dusty fan can actually blow dirty air back into your room, making allergies worse instead of better.

I learned this the hard way last winter. My allergies flared up like crazy, even though my Dyson was running nonstop. Turns out, I hadn’t cleaned the machine in over six months. The filter was packed with gunk, and the internal components were coated in dust. Once I finally gave it a proper deep clean, the difference was night and day—my air felt fresher, and my sneezing fits dropped by at least 80%.

Cleaning your Dyson Air Purifier Hot+Cold isn’t just about maintenance—it’s about performance, efficiency, and your health. In 2026, with smarter homes and tighter indoor air quality standards, keeping your purifier in top shape is more important than ever. Whether you’ve owned yours for a year or just unboxed a new one, knowing how to clean Dyson Air Purifier Hot Cold in 2026 will keep it running like new for years to come.

What You Need

Before we dive into the steps, let’s gather the essentials. You don’t need fancy tools or expensive cleaners—just a few household items and a little time.

• Soft microfiber cloths (at least two)
• Mild dish soap (unscented is best)
• White vinegar (for stubborn buildup)
• Compressed air can (optional but helpful)
• Small brush (like an old toothbrush or makeup brush)
• Lukewarm water
• Dyson filter replacement (if your filter is overdue—more on that later)

Pro tip: Always unplug your Dyson before cleaning. Safety first, always. And if your model has a washable filter (like the HEPA + Carbon combo in many Hot+Cold units), make sure it’s completely dry before reinserting—moisture can damage the motor.

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

Step 1: Turn Off and Unplug the Unit

Before touching anything, make sure your Dyson Air Purifier Hot+Cold is completely powered off and unplugged from the wall. This isn’t just a suggestion—it’s essential. Even if the machine seems off, internal components can still hold a charge.

I once made the mistake of wiping down the exterior while it was still plugged in. Not dangerous, but definitely not smart. Take 10 seconds to unplug it. Your future self will thank you.

Step 2: Remove the Outer Shell and Access the Filter

Most Dyson Hot+Cold models have a magnetic front cover that lifts off easily. Gently pull the front panel away from the base—there’s usually a soft click when it releases. Once it’s off, you’ll see the filter compartment.

Carefully slide out the filter. Depending on your model, you might have a single HEPA filter or a dual-layer system (HEPA + activated carbon). Take note of how it’s positioned so you can reinstall it correctly later.

If your filter looks gray, clogged, or has visible debris, it’s time for a clean or replacement. Dyson recommends replacing filters every 12 months under normal use, but if you have pets or live in a dusty area, you might need to do it sooner.

Step 3: Clean or Replace the Filter

Here’s where things get important: never wash a non-washable filter. Most Dyson filters are labeled “do not wash.” If yours is washable (check the manual or filter label), rinse it gently under lukewarm water until the water runs clear. Avoid soap—it can degrade the filter material.

After rinsing, shake off excess water and let it air-dry for at least 24 hours. Never speed-dry with a hairdryer or place it near a heater. Heat can warp the filter and ruin its effectiveness.

If your filter isn’t washable or is past its prime, replace it with a genuine Dyson filter. Counterfeit filters might seem cheaper, but they often don’t seal properly and can let unfiltered air slip through. I learned this after buying a third-party filter that caused my machine to underperform for weeks.

Step 4: Wipe Down the Interior and Fan Blades

With the filter removed, you’ll have access to the internal chamber. Use a dry microfiber cloth to gently wipe away dust from the walls and base. For tighter spots, a small brush works wonders.

Now, here’s a trick I picked up from a Dyson technician: use compressed air to blow dust off the fan blades. Hold the can upright and spray in short bursts. Don’t spin the fan manually—it can damage the motor. Let the air do the work.

If there’s sticky residue (from humidity or pet hair), dampen a cloth with a 50/50 mix of water and white vinegar. Wipe gently, then follow with a dry cloth to prevent moisture buildup.

Step 5: Clean the Exterior and Air Vents

The outside of your Dyson collects dust, fingerprints, and even grease from cooking. Use a slightly damp microfiber cloth with a drop of mild dish soap to wipe down the entire surface—front, back, sides, and base.

Pay special attention to the air intake and output vents. These areas get clogged fast, especially if you have pets or live in a city. Use a dry toothbrush to dislodge dust from the slats, then wipe clean.

Avoid spraying water directly onto the machine. Dampen the cloth instead—water and electronics don’t mix, even on the outside.

Step 6: Clean the Heating Element (If Applicable)

The “Hot” in Hot+Cold means this purifier can also warm your room. If you use the heating function, the internal heating element can accumulate dust over time.

While you can’t access the heating coil directly, you can clean around it. Use compressed air to blow dust away from the heating chamber. Never use water or liquid cleaners near this area—moisture can cause corrosion or electrical issues.

If your machine has a “Heating Element Clean” mode (some newer models do), run it once a month during heating season. It helps burn off light dust buildup safely.

Step 7: Reassemble and Test

Once everything is dry and clean, it’s time to put your Dyson back together. Slide the filter back into place, making sure it’s seated correctly. Reattach the front cover—listen for that satisfying magnetic click.

Plug the unit back in and turn it on. Run it on the lowest fan setting for 10–15 minutes to ensure everything is working smoothly. Listen for unusual noises or vibrations—these could mean something’s misaligned.

If the machine runs quietly and the air feels fresh, you’re good to go. Congrats—you’ve just mastered how to clean Dyson Air Purifier Hot Cold in 2026 like a pro.

Pro Tips & Common Mistakes to Avoid

Cleaning your Dyson isn’t rocket science, but there are a few pitfalls that trip people up. Here’s what I’ve learned from years of maintaining mine—and fixing mistakes along the way.

Pro Tip: Set a calendar reminder every 3 months to check your filter. Even if it doesn’t need cleaning yet, a quick visual inspection helps you stay ahead of buildup.

Warning: Never use bleach, ammonia, or abrasive cleaners. They can degrade plastic parts and leave harmful residues in the air.

One common mistake? Over-cleaning the filter. If you wash a washable filter too often, you can damage the delicate fibers. Stick to rinsing only when visibly dirty—usually every 3–6 months.

Another trap: assuming the machine is clean because the exterior looks fine. Dust loves to hide inside. I used to skip the internal cleaning until I noticed my purifier was louder than usual. A deep clean fixed the noise instantly.

Also, don’t ignore the remote. Wipe it down with a disinfectant wipe monthly. It’s one of the dirtiest things in your home—yet no one thinks to clean it.

Finally, if your Dyson starts making a rattling noise after cleaning, double-check that the filter is fully seated and the front cover is securely attached. Loose parts can cause vibrations that sound worse than they are.

FAQs About How to Clean Dyson Air Purifier Hot Cold in 2026

Q: How often should I clean my Dyson Air Purifier Hot+Cold?
A: For most users, a full clean every 3–6 months is ideal. If you have pets, smoke, or live in a high-pollen area, aim for every 2–3 months. The filter should be replaced annually, or sooner if it looks dirty.

Q: Can I vacuum the filter instead of washing it?
A: You can gently vacuum the surface of a washable filter to remove loose dust, but it won’t deep-clean it. For best results, rinse it under water when needed. Never vacuum a non-washable filter—it can tear the material.

Q: My Dyson smells musty after cleaning. What’s wrong?
A: That’s usually a sign of trapped moisture. Make sure the filter is 100% dry before reinserting. If the smell persists, run the purifier on high for an hour with the windows open to air it out. A few drops of lemon essential oil on a cloth (not in the machine) can help freshen the air.

Q: Is it safe to use the heating function right after cleaning?
A: Yes, as long as no water got inside the heating chamber. If you used compressed air or a dry cloth, you’re good to go. But if you suspect moisture, wait 24 hours before using the heat setting.

Q: Can I clean my Dyson with a steam cleaner?
A: Absolutely not. Steam introduces moisture into sensitive electronics and can warp plastic parts. Stick to dry or slightly damp cloths only.

Q: My purifier isn’t cooling as well as before. Could cleaning help?
A: Yes! A clogged filter or dusty fan reduces airflow, making the cooling effect weaker. Cleaning the internal components often restores performance. If it still underperforms, check for blockages in the vents or consider a filter replacement.

Q: Do I need to clean the remote control?
A: Yes! The remote collects oils, dust, and germs from your hands. Wipe it monthly with a disinfectant wipe. It’s a small step that makes a big difference in hygiene.

Final Thoughts

Cleaning your Dyson Air Purifier Hot+Cold might seem like a chore, but it’s one of the best things you can do for your home’s air quality—and your peace of mind. A well-maintained purifier runs quieter, lasts longer, and actually does its job: giving you cleaner, healthier air.

Think of it like changing the oil in your car. Skip it, and you’ll pay the price later. Do it regularly, and everything runs smoothly. In 2026, with air quality challenges on the rise, taking 30 minutes a few times a year to clean your Dyson is a small investment with huge returns.

So grab your microfiber cloth, unplug that machine, and give it the TLC it deserves. Your lungs—and your Dyson—will thank you. And if you’ve been putting it off? No judgment. Just start today. You’ve got this.
