Regularly cleaning your Levoit air purifier filter is essential to maintain peak performance and extend its lifespan. In 2026, the process remains simple: vacuum the pre-filter monthly, rinse the HEPA filter under cold water (if washable), and let it air dry completely before reinstalling. Never use harsh chemicals or submerge non-washable filters—this can damage sensitive components and void your warranty.

Why This Matters / Understanding the Problem

Let’s be honest: we all love our Levoit air purifiers. They quietly hum in the corner, filtering dust, pet dander, and even that weird cooking smell from last night’s stir-fry. But after a few months, you might notice something… off. The airflow slows. The noise increases. And the air just doesn’t feel as fresh.

That’s usually because the filter is clogged. And while Levoit makes some of the most user-friendly air purifiers on the market, cleaning the filter isn’t always straightforward. Some filters are washable. Others are not. And if you do it wrong? You could damage your device or shorten the filter’s lifespan.

So if you’re wondering “How to Clean Levoit Air Purifier Filter in 2026”—you’re not alone. In this guide, I’ll walk you through the exact steps I’ve used for my own Levoit Core 300 and 400 series units. I’ll share what works, what doesn’t, and how to keep your air clean without breaking a sweat.

Whether you’re dealing with a washable pre-filter or a HEPA filter that needs careful handling, this guide covers it all—with real-world tips from months of testing.

What You Need

Before we dive in, let’s gather your supplies. Nothing fancy—just a few basics you probably already have at home.

• Soft microfiber cloth (or a lint-free towel)
• Vacuum with a brush attachment (handheld or upright works)
• Mild dish soap (optional, only for washable pre-filters)
• Warm water (not hot—keep it lukewarm)
• Soft-bristled brush (like an old toothbrush or paintbrush)
• Drying rack or clean towel (for air-drying)
• Replacement HEPA filter (if yours is due—check your model’s lifespan)

Pro tip: Always check your specific Levoit model. The Core 200S, Core 300, Core 400S, and LV-H132 all have slightly different filter systems. But the core principles of how to clean Levoit air purifier filter in 2026 remain consistent.

You’ll also want to unplug your purifier before starting. Safety first, right?

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

Step 1: Power Off & Remove the Filter

Start by turning off your Levoit air purifier and unplugging it from the wall. This isn’t just about safety—it also gives the unit time to cool down and prevents dust from being pulled in during cleaning.

Now, locate the filter compartment. On most models (like the Core 300), it’s at the back or bottom. You’ll see a latch or a twist-lock mechanism. Gently open it—don’t force anything. If it’s stiff, wiggle it slightly.

Once open, you’ll see the filter housing. Pull it out carefully. Some models have a pre-filter wrapped around the main HEPA filter. Others keep them separate. Take note of how it’s arranged—you’ll want to reinstall it the same way.

Warning: Don’t yank the filter. The HEPA material is fragile. A sudden pull can tear it or dislodge the frame. Think of it like handling a delicate pastry—gentle hands only.

Step 2: Separate the Pre-Filter (If Washable)

Most Levoit purifiers have a washable pre-filter—usually a mesh or foam layer that traps large particles like hair, lint, and dust bunnies. This is the first line of defense, and it’s the one you can clean.

Look for a zipper or Velcro strip around the edge of the pre-filter. Unzip or unwrap it. If your model has a standalone pre-filter (like the Core 400S), it’ll just slide off the main HEPA filter.

Now, inspect it. If it’s covered in dust and pet hair (like mine after three months with two cats), it’s definitely due for cleaning. But if it’s just lightly dusty? A quick vacuum might be enough.

For a deeper clean, here’s what I do:

• Rinse it under lukewarm water (never hot—it can warp the mesh)
• Add a drop of mild dish soap if it’s really grimy
• Use a soft brush to gently scrub the surface—don’t press hard
• Rinse thoroughly until all soap is gone

After rinsing, shake off excess water and let it air-dry completely—this can take 4–6 hours. Never put it in the dryer or use a hairdryer. Heat ruins the mesh.

Pro Tip: I keep a spare pre-filter in my drawer. That way, I can swap it while the other dries. No downtime for my air purifier!

Step 3: Vacuum the Main HEPA Filter (Do NOT Wash It!)

This is the big one: you cannot wash the HEPA filter. I learned this the hard way when I tried rinsing mine—only to realize it was ruined and had to be replaced.

The HEPA (High-Efficiency Particulate Air) filter is made of delicate paper-like fibers. Water destroys its structure and makes it ineffective. So what can you do?

Vacuum it—gently.

Use your vacuum’s brush attachment and set it to low suction (if possible). Hold the nozzle about 1–2 inches away from the filter surface. Work in slow, overlapping strokes from top to bottom.

Focus on both sides. The outside will be dusty. The inside (the side facing the fan) might have finer particles.

For stubborn spots, I use a soft-bristled brush to loosen dust before vacuuming. Think of it like dusting a bookshelf—light, deliberate movements.

Warning: Don’t use compressed air. The force can damage the HEPA fibers. And never poke or prod the filter with sharp objects.

After vacuuming, inspect the filter. If it’s still gray or black after cleaning, it’s likely at the end of its life. Most Levoit HEPA filters last 6–8 months with regular use. But if you have pets, smokers, or live in a dusty area? Replace it every 4–5 months.

Step 4: Clean the Air Purifier Housing

While the filters are out, take a few minutes to clean the inside of your purifier. Dust and debris love to settle in the corners and fan area.

Use your vacuum’s crevice tool to suck up loose dust. Then, wipe the interior with a dry microfiber cloth. If there’s sticky residue (like from a spilled drink), dampen the cloth slightly—but never let water drip inside.

Check the fan blades. They’re usually hidden behind a grill. If you can reach them, gently wipe them with the cloth. Don’t use water here—just dry cleaning.

Also, clean the air intake and outlet grills. A soft brush or cloth works best. These areas can get clogged with pet hair or dust, reducing airflow.

Pro Tip: I clean the housing every time I clean the filter. It only takes 5 minutes, and it keeps my purifier running smoothly.

Step 5: Reassemble the Filters

Now that everything is clean and dry, it’s time to put it all back.

Start with the pre-filter. If it’s washable, make sure it’s 100% dry before reattaching it to the HEPA filter. Any moisture can lead to mold or mildew inside the purifier.

Wrap it around the HEPA filter, then zip or fasten it securely. For models with separate pre-filters, slide it back into place.

Now, carefully insert the entire filter assembly back into the purifier. Make sure it sits flat and the latch or door closes smoothly. You should hear a “click” or feel it lock into place.

Double-check that the filter is seated correctly. A misaligned filter can cause air leaks, reducing efficiency.

Step 6: Reset the Filter Indicator (If Applicable)

Many Levoit models (like the Core 300S and 400S) have a filter replacement indicator light. It’s a helpful reminder—but it doesn’t know you just cleaned the pre-filter.

After reassembling, you need to reset the timer.

Here’s how (steps vary slightly by model):

• Press and hold the “Filter Reset” button for 3–5 seconds
• On some models, press the “Light” button 3 times quickly
• The indicator light should blink or turn off

Consult your user manual if you’re unsure. But most modern Levoit purifiers make this pretty intuitive.

Note: You only reset the timer if you cleaned the filter. If you replaced the HEPA filter, reset it immediately. If you just cleaned the pre-filter, reset it after cleaning—but remember, the HEPA filter’s lifespan is still ticking.

Step 7: Run a Test Cycle

Plug your purifier back in and turn it on. Let it run for 10–15 minutes on medium or high.

Listen for unusual noises. A clean purifier should run smoothly and quietly. If it’s rattling or making a grinding sound, double-check that the filter is seated properly.

Feel the airflow at the top. It should be strong and steady. If it’s weak, the filter might still be clogged or not installed correctly.

Also, check for any strange smells. A musty odor could mean mold in the housing or a damp pre-filter. If that happens, open it up and inspect again.

Pro Tips & Common Mistakes to Avoid

Over the past year, I’ve cleaned my Levoit purifier every 4–6 weeks. Here are the lessons I’ve learned—some the hard way.

Clean the Pre-Filter Every 2–4 Weeks

Don’t wait until it’s black. A slightly dusty pre-filter can still restrict airflow. I clean mine every 3 weeks, especially during pollen season or if my cats are shedding.

Never Use Water on the HEPA Filter

I’ve seen people try to wash HEPA filters with soapy water, rinse them, or even soak them. Don’t do it. Water breaks down the fibers, and the filter becomes useless. Vacuuming is the only safe method.

Don’t Skip the Housing

It’s tempting to just clean the filters and call it a day. But dust in the housing can get sucked back in, re-clogging your filter faster. Take 5 minutes to wipe it down.

Check for Filter Damage

Every time you clean, inspect both filters for tears, holes, or warping. A damaged pre-filter won’t catch dust. A damaged HEPA filter won’t trap particles. Replace either if you see damage.

Label Your Filters (Optional but Smart)

I write the date on my HEPA filter with a permanent marker. That way, I know exactly when to replace it. No guessing games.

Use Genuine Replacement Filters

Third-party filters might seem cheaper, but they often don’t fit properly or meet HEPA standards. I’ve used off-brand filters before—and my purifier worked, but the air quality wasn’t as good. Stick with Levoit’s official filters for best results.

Clean in a Dust-Free Area

I used to clean my purifier in the garage. Big mistake. Dust settled on the filters while they dried. Now I clean them indoors, near a closed window, and cover them with a clean cloth while drying.

Warning: If you have allergies or asthma, wear a mask during cleaning. Disturbing the filter can release trapped particles into the air.

FAQs About How to Clean Levoit Air Purifier Filter in 2026

Can I wash the HEPA filter in my Levoit purifier?

No, and I’ve tested this. The HEPA filter is made of paper-like fibers that break down when wet. Washing it—even with a gentle rinse—will ruin its ability to trap particles. The only safe way to clean it is with a vacuum and soft brush.

Stick to vacuuming, and replace the HEPA filter every 6–8 months (sooner if you have pets or allergies).

How often should I clean the pre-filter?

I clean mine every 2–4 weeks, depending on use. If you have pets, smokers, or live in a dusty area, clean it every 2 weeks. For light use (like a bedroom with no pets), every 4 weeks is fine.

The key is to check it monthly. If it’s gray or covered in hair, it’s time to clean.

My filter indicator light is on, but I just cleaned the pre-filter. Do I need a new HEPA filter?

Not necessarily. The indicator tracks total usage time, not just the pre-filter. If you’ve cleaned the pre-filter but the HEPA filter is still in good shape (no tears, still white/gray), you can reset the timer and keep using it.

But if the HEPA filter is dark, smelly, or damaged, it’s time to replace it. The indicator is a helpful guide, but your eyes and nose are better judges.

Can I use compressed air to clean the HEPA filter?

Technically, yes—but I don’t recommend it. The high pressure can damage the delicate fibers. If you must, use the lowest setting and hold the nozzle at least 6 inches away. Even then, vacuuming is safer and more effective.

How do I know if my filter is damaged?

Look for:

• Tears or holes in the material
• Warping or bent frames
• Discoloration beyond normal use (like black mold)
• Persistent musty smell after cleaning

If you see any of these, replace the filter. A damaged filter can’t clean the air—and may even release trapped particles back into your home.

Can I reuse a washable pre-filter forever?

Eventually, no. Even washable filters wear out. The mesh can stretch, tear, or lose its ability to trap dust. I replace my pre-filters every 12–18 months, even if they look okay. It’s a small cost for better air quality.

What’s the best way to dry the pre-filter?

Air-dry it flat on a clean towel or drying rack. Keep it out of direct sunlight and heat sources. I leave mine overnight. Never use a hairdryer, oven, or radiator—heat warps the mesh.

Final Thoughts

Cleaning your Levoit air purifier filter doesn’t have to be complicated. With the right tools and a little routine, you can keep your purifier running like new—and your air fresh and clean.

Remember: clean the pre-filter every few weeks, vacuum the HEPA filter monthly, and replace both when needed. It’s that simple.

And when you’re following how to clean Levoit air purifier filter in 2026, focus on gentle, consistent care. No harsh chemicals. No water on the HEPA. Just patience and attention to detail.

Your purifier will last longer. Your air will be healthier. And you’ll avoid that annoying “filter replacement” light for months.

So grab your vacuum, set a reminder on your phone, and make this part of your monthly cleaning routine. Your lungs will thank you.
