How to Clean Xiaomi Air Purifier Fan in 2026 for Best Performance

Key Takeaways

• Turn off and unplug the purifier before cleaning for safety.
• Remove and vacuum the filter gently to remove surface dust.
• Wash reusable filters with lukewarm water and let them air dry completely.
• Wipe the fan blades with a damp cloth to prevent dust buildup.
• Clean the exterior regularly with a soft, dry microfiber cloth.
• Replace HEPA filters every 6–12 months for optimal performance.

Why This Matters / Understanding the Problem

Let’s be honest—how often do you think about your Xiaomi air purifier after setting it up? You turn it on, it hums quietly in the corner, and you assume it’s doing its job. But here’s the thing: over time, dust, pet hair, and allergens build up inside the fan and filters, making it work harder and less efficiently.

If you’ve noticed weaker airflow, louder operation, or that your allergies are flaring up again, it’s probably time for a deep clean. Cleaning your Xiaomi air purifier fan isn’t just about hygiene—it’s about how to clean Xiaomi air purifier fan in 2026 for best performance, ensuring it lasts longer and keeps your air fresh.

I learned this the hard way. After six months of use, my Mi Air Purifier 3C started making a weird grinding noise. A quick inspection revealed a dust bunny party in the fan blades. A 20-minute clean later? Silent, powerful airflow again. That’s when I realized: regular maintenance isn’t optional. It’s essential.

And in 2026, with rising air quality concerns and more smart homes, keeping your purifier in top shape is more important than ever. Whether you have the Mi Air Purifier 2S, 3H, Pro H, or the newer models with laser particle sensors, the cleaning principles remain similar. Let’s fix this—step by step.

What You Need

Before we dive into the cleaning process, gather these tools. Most are already in your home, and none cost more than a coffee.

• Soft microfiber cloth (or lint-free cotton cloth) – for wiping surfaces
• Vacuum with a brush attachment – for loose dust and debris
• Compressed air can (optional, but helpful for tight spaces)
• Soft-bristled brush (like a clean toothbrush or electronics brush) – for fan blades
• Small bowl of lukewarm water – for damp cleaning (never soak the device)
• Dish soap (mild, non-abrasive) – just a drop for sticky spots
• Replacement pre-filter (if yours is beyond cleaning)
• Replacement HEPA filter (check your model’s lifespan—usually 6–12 months)
• Smartphone or tablet – to monitor filter life via the Mi Home app

Pro insight: Never use harsh chemicals, bleach, or abrasive scrubbers. These can damage the plastic housing, fan blades, or filter membranes. Your purifier isn’t a kitchen appliance—treat it gently.

Step-by-Step Guide to How to Clean Xiaomi Air Purifier Fan in 2026 for Best Performance

Step 1: Power Off and Unplug the Unit

First things first: safety. Unplug your Xiaomi air purifier from the wall. Even if it’s “off,” internal capacitors can still hold a charge. This isn’t just about preventing shocks—it’s about protecting the motor and electronics during cleaning.

I once skipped this step (in a hurry, of course), and the fan started spinning when I pressed the power button. Not a good feeling. Lesson learned: always unplug. It takes two seconds and saves you a lot of stress.

Also, let the unit cool down if it’s been running for hours. Warm plastic can warp or become more fragile when wiped.

Step 2: Remove and Inspect the Filters

Most Xiaomi air purifiers (2S, 3H, Pro H) use a 3-in-1 filter system: pre-filter, HEPA filter, and activated carbon filter. Start by opening the front or side panel—usually a simple latch or magnetic cover.

Carefully pull out the filter assembly. Hold it by the edges to avoid tearing the HEPA layer. Now, inspect each layer:

• Pre-filter (outer mesh): Look for visible dust, pet hair, or debris. If it’s caked, it’s time to clean or replace.
• HEPA filter (middle layer): Should be white or off-white. If it’s gray or black, it’s clogged and needs replacing—no amount of cleaning will fix it.
• Carbon filter (inner layer): Smell it. If it no longer has a fresh, clean scent, it’s saturated and ineffective.

Warning: Never wash or vacuum the HEPA or carbon filters. They’re made of delicate fibers and will lose effectiveness if damaged. Only the pre-filter can be cleaned.

For how to clean Xiaomi air purifier fan in 2026 for best performance, remember: clean filters = better airflow = longer motor life.

Step 3: Clean the Pre-Filter

The pre-filter is your first line of defense. It catches large particles like hair, lint, and dust. Over time, it gets clogged—reducing airflow and forcing the fan to work harder.

Here’s how to clean it:

• Take the pre-filter to the sink or a bowl.
• Rinse under lukewarm water (never hot—it can warp the mesh).
• If sticky, add a tiny drop of mild dish soap and gently scrub with a soft brush.
• Rinse thoroughly to remove all soap residue.
• Shake off excess water and lay flat on a clean towel.
• Let it air dry completely—usually 1–2 hours. Do not use a hairdryer or place in direct sunlight.

I’ve made the mistake of reinserting a damp pre-filter. It led to mold growth inside the unit. Not fun. Always wait until it’s bone dry.

Step 4: Vacuum the Interior and Fan Housing

Now, let’s tackle the fan and internal chamber. This is where dust accumulates and affects performance.

• Use your vacuum’s brush attachment to gently suck up dust from the inner walls, fan housing, and air intake vents.
• Pay special attention to corners and crevices where dust loves to hide.
• For stubborn dust on fan blades, use the soft-bristled brush to loosen it, then vacuum.
• If you have a compressed air can, use short bursts to blow dust out of tight spots (keep the can upright to avoid liquid spray).

Pro tip: Hold the fan blades steady while cleaning. Don’t let them spin freely—this can damage the motor bearings over time.

This step is crucial for how to clean Xiaomi air purifier fan in 2026 for best performance. A clean fan spins smoothly, uses less energy, and lasts longer.

Step 5: Wipe Down the Exterior and Control Panel

The outside of your purifier collects fingerprints, dust, and pet dander. A quick wipe keeps it looking fresh and prevents grime from being sucked into the system.

• Dampen a microfiber cloth with water (wring it out well—no dripping).
• Wipe the entire exterior, including the top, sides, and base.
• For sticky spots, use a cloth with a tiny drop of dish soap, then wipe with a clean, damp cloth to remove residue.
• Dry immediately with a dry microfiber cloth.

For the touchscreen or LED display (on models like the 3H or Pro H), use a dry microfiber cloth only. Never use water or cleaning sprays directly on the screen.

I once used a disinfectant wipe on the display—big mistake. The chemicals smudged the coating. Now I only use dry cloths.

Step 6: Clean the Air Outlet and Fan Blades (If Accessible)

Some models (like the Pro H) have a detachable top grill or outlet cover. If yours does, remove it and clean the fan blades directly.

• Use the soft brush to remove dust from each blade.
• Vacuum or blow with compressed air.
• Wipe the inside of the outlet grill with a damp cloth, then dry.

If your model doesn’t allow blade access (like the 2S), don’t force it. Instead, use compressed air to blow dust from the outside in through the outlet. It’s less thorough, but better than nothing.

Warning: Never insert fingers or tools into the fan while the unit is plugged in—even if it’s off. Safety first.

Step 7: Reassemble and Reset the Filter Timer

Once everything is dry, reinsert the filters in the correct order: pre-filter (cleaned or new), HEPA, carbon. Make sure they’re seated properly—no gaps or misalignment.

Close the cover securely. Now, open the Mi Home app on your phone:

• Go to your purifier’s device page.
• Tap “Filter Life” or “Maintenance.”
• Reset the pre-filter timer (if you cleaned it).
• Replace the HEPA/carbon filter timer if you installed a new one.

Resetting the timer ensures your app gives accurate reminders. Otherwise, it might tell you to replace filters too soon—or worse, too late.

This step is a key part of how to clean Xiaomi air purifier fan in 2026 for best performance. Smart reminders keep you on track.

Step 8: Run a Test Cycle

Plug the unit back in. Turn it on and set it to “Auto” mode. Listen closely:

• Is the fan running smoothly?
• Is the airflow stronger than before?
• Any unusual noises?

Let it run for 15–30 minutes. The air should feel fresher, and the noise level should be lower. If it’s still loud, double-check that all parts are properly seated and nothing is blocking the airflow.

Bonus: open the Mi Home app and check the PM2.5 reading. A clean purifier should show a faster drop in particle levels.

Pro Tips & Common Mistakes to Avoid

After cleaning dozens of Xiaomi purifiers (mine and friends’), here’s what I’ve learned:

• Clean every 2–4 weeks if you have pets, live in a dusty area, or run the purifier 24/7. Otherwise, every 6–8 weeks is fine.
• Replace filters on time—don’t stretch it. A clogged HEPA filter can damage the motor.
• Use genuine Xiaomi filters when possible. Third-party filters may not fit perfectly, reducing efficiency.
• Keep the purifier away from moisture—no steam, no wet walls. Humidity can warp filters and promote mold.
• Don’t ignore the pre-filter—it’s the cheapest part, but the most critical for fan health.

Common mistake: People think “cleaning” means just wiping the outside. But the real magic happens inside—especially on the fan and filters. That’s where how to clean Xiaomi air purifier fan in 2026 for best performance truly makes a difference.

Pro insight: If your purifier has a laser particle sensor (like the Pro H), gently wipe the sensor window with a dry microfiber cloth every few months. Dust on the lens can skew readings.

One friend ignored her purifier for a year. When she finally opened it, the fan was so caked in dust it wouldn’t spin. The motor burned out within a week. A $50 repair could’ve been avoided with a $0 cleaning.

FAQs About How to Clean Xiaomi Air Purifier Fan in 2026 for Best Performance

Can I wash the HEPA filter?

No. The HEPA filter is made of ultra-fine glass fibers. Water, vacuuming, or brushing will damage it permanently. Once it’s gray or smells stale, replace it. Cleaning only applies to the outer pre-filter.

How often should I clean the fan blades?

Every 6–8 weeks under normal use. If you have pets, smokers, or live in a high-pollution area, clean every 3–4 weeks. The fan blades are the heart of the system—clean them to maintain airflow and efficiency.

Why is my Xiaomi air purifier loud after cleaning?

Usually, it’s because something isn’t seated right. Double-check that the filters are in the correct order and the cover is fully closed. Also, ensure no cloth or debris is stuck in the fan. If the noise persists, the motor bearings may be worn—contact Xiaomi support.

Can I use a vacuum cleaner on the HEPA filter?

No. Vacuuming can tear or compress the HEPA fibers, reducing filtration by up to 90%. The only safe cleaning method for HEPA is replacement.

What if my pre-filter is torn or damaged?

Replace it. A damaged pre-filter can’t catch large particles, so dust flows straight into the HEPA filter, clogging it faster. Genuine Xiaomi pre-filters are affordable and widely available.

Does cleaning affect the smart features?

Not directly, but if you reset the filter timer in the Mi Home app after cleaning, the smart reminders will stay accurate. That’s a big part of how to clean Xiaomi air purifier fan in 2026 for best performance—using tech to stay on schedule.

Is it safe to clean while the purifier is on?

Absolutely not. Unplug it first. Even if the fan isn’t spinning, internal components can be damaged by moisture or physical contact. Safety isn’t optional.
