How to Clean Levoit True HEPA Air Purifier in 2026

Key Takeaways

• Unplug the purifier before cleaning to ensure safety.
• Vacuum the exterior and vents weekly to remove dust buildup.
• Wipe the filter cover with a damp cloth monthly.
• Never wash the HEPA filter—replace it every 6–8 months.
• Clean the pre-filter every 2–4 weeks with mild soap and water.

Why This Matters / Understanding the Problem

Let’s be honest—air purifiers are one of those appliances we *set and forget*. You plug in your Levoit True HEPA Air Purifier, breathe easier, and then… well, you kind of forget about it. Out of sight, out of mind, right?

But here’s the thing: dust, pet dander, and even mold spores can build up inside your purifier over time. And if you don’t clean it regularly, it stops working as well—or worse, it starts pushing dirty air back into your space.

I learned this the hard way after my purifier started making a weird humming noise. I opened it up and found the pre-filter packed with dust like a used coffee bag. That’s when I realized: cleaning isn’t optional—it’s essential.

If you’re searching for how to clean Levoit True HEPA Air Purifier in 2026, you’re already ahead of the game. Regular maintenance keeps your air quality high, your energy bills low, and your purifier running for years—not months.

And don’t worry—this isn’t a complicated science experiment. It’s a simple routine you can do in under 30 minutes, once every few weeks. Let’s get into it.

What You Need

Before we dive into the steps, let’s gather what you’ll need. Nothing fancy—just a few household items and a little elbow grease.

• Microfiber cloth – soft, lint-free, and perfect for wiping down plastic and filters
• Soft brush – a clean paintbrush, makeup brush, or even an old toothbrush works
• Vacuum with a brush attachment – for sucking up dust without damaging filters
• Compressed air canister (optional) – great for stubborn dust in tight spaces
• Mild dish soap and warm water – for cleaning the outer shell and pre-filter
• Timer or phone reminder – trust me, you’ll thank yourself later
• Replacement filters (if needed) – check your model (Core 300, 400S, etc.) and keep spares on hand

Pro tip: Always unplug your purifier before cleaning. Safety first—no exceptions.

Once you have these, you’re ready to tackle how to clean Levoit True HEPA Air Purifier in 2026 like a pro.

Step-by-Step Guide to How to Clean Levoit True HEPA Air Purifier in 2026

Cleaning your Levoit isn’t just about wiping the outside. It’s about systematic maintenance—tackling each part to keep airflow smooth and filtration effective. Here’s how to do it right.

Step 1: Power Down and Unplug

First things first: turn off and unplug your air purifier. Even if it’s just for cleaning, electricity and water don’t mix. I once forgot this step (don’t judge) and nearly shocked myself when I reached for a damp cloth near the power port.

Give it a minute to cool down if it’s been running. You don’t want to burn your fingers on warm plastic or motors.

Why this matters: Unplugging prevents accidental startup and protects internal electronics from moisture damage.

Step 2: Remove the Pre-Filter

The pre-filter is the first line of defense. It catches big particles like pet hair, dust bunnies, and lint. On most Levoit models (like the Core 300 or 400S), it’s a thin mesh screen on the outside.

To remove it:

• Twist or slide the front cover off (check your manual if unsure)
• Gently pull the pre-filter out—it’s usually held by small clips or magnetic strips

Hold it up to the light. If it looks like a dust storm hit it, it’s definitely time to clean. I once found a whole spider web in mine—yikes.

Note: Never wash the HEPA or carbon filter. Only the pre-filter is washable.

Step 3: Clean the Pre-Filter

Now, let’s get that pre-filter clean. Here’s how:

• Rinse it under warm (not hot) water to loosen dust
• Add a few drops of mild dish soap and gently scrub with a soft brush
• Rinse thoroughly until no soap bubbles remain
• Shake off excess water and lay it flat to air dry completely—no towels, no heat

I usually leave mine on a clean towel for 3–4 hours. Never rush this step—wet filters can mold or damage the purifier.

While it dries, move on to the next step.

Step 4: Vacuum the Interior and Filter Housing

Now, open the main chamber where the HEPA and carbon filters sit. Use your vacuum’s brush attachment to:

• Suction dust from the filter housing
• Clean around the fan blades (gently!)
• Remove debris from the intake vents

I like to use a flashlight to spot hidden dust. You’d be surprised how much collects in the corners.

For tight spots (like between fan blades), a compressed air can works wonders. Just don’t spray too close—hold it 6–8 inches away to avoid damage.

Caution: Never vacuum the HEPA filter directly—this can tear the delicate fibers.

Step 5: Wipe Down the HEPA and Carbon Filters (Surface Only)

You should not wash or vacuum the HEPA or carbon filters. But you *can* gently wipe the outside with a dry microfiber cloth to remove surface dust.

For stubborn particles, lightly brush the surface with a soft brush. Think of it like dusting a painting—gentle, precise, and careful.

I do this every 2–3 cleanings. It helps maintain airflow without risking filter damage.

Pro tip: Label your filters with the date you installed them. I use a small sticker—makes replacement easy to track.

Step 6: Clean the Exterior and Control Panel

Now, let’s make the outside look fresh. Dampen a microfiber cloth with a mix of:

• 1 part mild dish soap
• 3 parts warm water

Wipe down the entire outer shell—front, sides, back, and top. Pay attention to the vents and control panel. Use a cotton swab for tiny crevices around buttons.

Never spray water directly on the purifier. Always dampen the cloth first to avoid liquid seeping into electronics.

I once used a wet rag and shorted the touch controls. Learned my lesson—now I use a barely damp cloth.

Step 7: Reassemble and Test

Once everything is dry (especially the pre-filter!), it’s time to put it back together:

• Reinsert the HEPA and carbon filters in the correct order
• Snap the pre-filter back in place
• Close the front cover securely

Plug it back in and turn it on. Listen for smooth airflow—no rattling or grinding. If it sounds off, double-check that all parts are seated correctly.

I always run it on medium speed for 10 minutes to make sure everything’s working before setting it to auto or sleep mode.

Step 8: Reset the Filter Timer (If Applicable)

Many Levoit models have a filter replacement indicator. After cleaning (or replacing) the pre-filter, you’ll want to reset the timer.

On models like the Core 300S:

• Press and hold the “Filter” button for 3 seconds
• The indicator light should turn green

This ensures your purifier gives accurate reminders for future cleanings and replacements.

No reset? No problem. Just mark your calendar or set a phone reminder for next time.

Step 9: Set a Cleaning Schedule

Here’s the secret to long-term success: consistency.

I clean my pre-filter every 2 weeks and do a full internal wipe-down every month. If you have pets or live in a dusty area, go weekly.

Set a recurring reminder on your phone: “Clean Levoit Air Purifier.” I use Google Calendar—it emails me every other Sunday.

And remember: how to clean Levoit True HEPA Air Purifier in 2026 isn’t a one-time thing. It’s a habit that pays off in cleaner air and longer device life.

Pro Tips & Common Mistakes to Avoid

After years of cleaning my own purifiers (and making a few blunders), here’s what I wish I knew sooner.

✅ Pro Tip 1: Use a filter cover for pets
If you have cats or dogs, their hair gets everywhere. I started using a mesh filter cover (sold separately) on the pre-filter. It cuts down on hair buildup by 70%—game changer.

✅ Pro Tip 2: Keep a cleaning log
I keep a small notebook by my purifier. I write down:

• Date of cleaning
• Which filters I replaced
• Any issues (e.g., “fan was loud”)

It helps me spot patterns—like if the HEPA filter needs replacing earlier than expected.

✅ Pro Tip 3: Clean in a well-ventilated area
I used to clean mine in the kitchen, but dust and soap fumes made the room feel stuffy. Now I do it in the garage or near an open window. Fresh air helps everything dry faster, too.

🚫 Mistake 1: Rushing the drying process
I once put a damp pre-filter back in—big mistake. It started smelling musty after a week. Now I wait at least 4 hours. Overnight is even better.

🚫 Mistake 2: Using harsh cleaners
Bleach, ammonia, or strong disinfectants can damage plastic and filter materials. Stick to mild soap and water. Your purifier isn’t a toilet—it doesn’t need heavy chemicals.

🚫 Mistake 3: Forgetting the fan
The fan blades collect dust, but they’re easy to overlook. A dusty fan means reduced airflow and more strain on the motor. Vacuum them gently every 1–2 months.

🚫 Mistake 4: Ignoring the manual
Every Levoit model is slightly different. The Core 200S opens differently than the 400S. Always check your manual before disassembling. It’s free on Levoit’s website if you’ve lost it.

🚫 Mistake 5: Not replacing filters on time
Cleaning helps, but it can’t extend a filter’s life forever. The HEPA filter lasts 6–12 months, and the carbon filter 3–6 months (depending on use). When airflow drops or odors return, it’s time to replace.

My rule of thumb: If I can’t see light through the pre-filter, it’s time to replace it—even if it’s not due yet.

FAQs About How to Clean Levoit True HEPA Air Purifier in 2026

Q: How often should I clean my Levoit air purifier?
A: I clean the pre-filter every 2 weeks and do a full wipe-down every month. If you have allergies, pets, or live in a dusty area, go weekly. The key to how to clean Levoit True HEPA Air Purifier in 2026 is consistency—not perfection.

Q: Can I wash the HEPA filter?
A: No. The HEPA filter is made of fine glass fibers. Water or vacuuming will destroy it. Just wipe the surface with a dry cloth. When airflow drops or it’s past its lifespan (6–12 months), replace it.

Q: My purifier is making a loud noise after cleaning. What’s wrong?
A: This usually means something isn’t seated correctly. Check that:

• The filters are in the right order
• The pre-filter is fully snapped in
• The front cover is closed tightly

Also, make sure nothing is blocking the fan. A loose screw or dust clump can cause rattling.

Q: How do I know when to replace the filters?
A: Look for signs like:

• Reduced airflow
• Persistent odors (especially smoke or pet smells)
• The filter replacement light is on
• The filter looks gray or black (not white or light gray)

Most Levoit models have a built-in timer, but I also recommend tracking dates manually.

Q: Can I use vinegar to clean the purifier?
A: Vinegar is great for descaling kettles, but not for air purifiers. The acid can damage plastic and rubber seals. Stick to mild soap and water.

Q: What if I lost my manual?
A: No worries! Levoit offers free PDF manuals on their support page. Just enter your model number (usually on the bottom or back of the unit).

Q: Is it safe to run the purifier while cleaning nearby?
A: No. Always unplug it first. Also, avoid using other appliances (like vacuum cleaners) that stir up dust while cleaning the purifier. I learned this when my vacuum kicked up a dust cloud—defeating the whole purpose.

Final Thoughts

Cleaning your Levoit True HEPA Air Purifier isn’t just about keeping it looking nice—it’s about protecting your health and your investment.

When you take 20 minutes every few weeks to clean it, you’re not just removing dust. You’re ensuring it captures allergens, smoke, and pollutants effectively. You’re also extending its lifespan—saving money on replacements.

I used to think air purifiers were “set and forget.” Now I see them as part of my home wellness routine, like changing HVAC filters or cleaning the fridge coils.

So, here’s my final advice: Start small. Clean the pre-filter this weekend. Set a reminder for two weeks from now. Keep a log. And if you ever feel overwhelmed, just remember—how to clean Levoit True HEPA Air Purifier in 2026 is a skill, not a chore.

You’ve got this. And your lungs will thank you.

One last tip: Pair your cleaning with a quick wipe of your windows and vents. It’s a mini air quality reset—and feels oddly satisfying.
