Key Takeaways

• Unplug first: Always disconnect power before cleaning for safety.
• Vacuum pre-filters: Remove large debris with a vacuum attachment.
• Rinse washable filters: Use lukewarm water—never soap or scrubbing.
• Dry completely: Air-dry filters 24+ hours to prevent mold growth.

Why This Matters: Understanding the Problem

Let’s be real—your Levoit air purifier works hard every day to keep your home’s air fresh and clean. But if you’ve noticed it’s not running as smoothly as it used to, or maybe the airflow feels weaker, chances are your filters need some love. I learned this the hard way last winter when my purifier started making a weird humming noise and my allergies flared up again. Turns out, I hadn’t cleaned the filters in months.

Cleaning your Levoit air purifier filters isn’t just about maintenance—it’s about performance, efficiency, and even your health. Over time, dust, pet dander, pollen, and other airborne particles build up on the filters. If left unchecked, this gunk can clog the system, reduce airflow, and even cause the motor to overwork. Worse? It might start blowing dirty air back into your room instead of cleaning it.

That’s why knowing how to clean Levoit air purifier filters in 2026 isn’t just a nice-to-have skill—it’s essential. Whether you’re using a Core 300, LV-H132, or any other Levoit model, regular cleaning keeps your unit running like new. And the best part? It’s easier than you think. No tools, no complicated steps—just a few minutes of your time can make a huge difference.

In this guide, I’ll walk you through everything you need to know, from what supplies to grab to step-by-step cleaning instructions. I’ll also share some pro tips I’ve picked up from years of using Levoit purifiers, plus common mistakes to avoid. By the end, you’ll feel confident maintaining your air purifier like a pro—and breathing easier because of it.

What You Need

Before we dive into the cleaning process, let’s make sure you have the right tools on hand. The good news? You probably already have most of these at home. Here’s a quick checklist:

• Soft-bristle brush (like an old toothbrush or makeup brush)
• Vacuum cleaner with a hose attachment
• Mild dish soap (optional, for washable pre-filters)
• Clean, dry cloth or microfiber towel
• Lukewarm water (never hot!)
• Replacement filters (if your HEPA or carbon filter is due for a swap)

Most Levoit models come with a pre-filter, a HEPA filter, and sometimes a carbon filter. The pre-filter is usually washable, while the HEPA and carbon filters are typically not—but they still benefit from gentle vacuuming. Always check your user manual to confirm which filters are washable and which aren’t. For example, the Core 300 has a washable pre-filter, but the HEPA H13 filter should never get wet.

Pro tip: Set a calendar reminder every 2–3 months to check and clean your filters. Consistency is key—don’t wait until your purifier starts acting up. A little prevention goes a long way in extending the life of your unit and keeping your air truly clean.

Step-by-Step Guide to How to Clean Levoit Air Purifier Filters in 2026: Expert Tips

Step 1: Turn Off and Unplug Your Air Purifier

First things first—safety first! Always turn off your Levoit air purifier and unplug it from the wall before you start cleaning. I learned this the hard way when I once tried to clean a filter while the unit was still running. Spoiler: it didn’t end well. Not only is it dangerous, but you also risk damaging the motor or internal components.

Once it’s unplugged, give the unit a minute to cool down if it’s been running. This is especially important if you’ve been using it on high speed for hours. A cool unit is easier to handle and less likely to warp or crack during cleaning.

Step 2: Remove the Front Cover and Access the Filters

Now, gently remove the front cover of your air purifier. Most Levoit models have a magnetic or snap-on cover that lifts off easily. On the Core 300, for example, you just pull the front panel forward and it comes right off. On older models like the LV-H132, you might need to press a small release button.

Once the cover is off, you’ll see the filters inside. Take note of how they’re positioned—this will help you reassemble everything correctly later. I like to take a quick photo with my phone before removing anything. It’s a simple trick, but it saves me from second-guessing later.

Step 3: Remove the Pre-Filter

The pre-filter is usually the outermost layer and the first line of defense against large particles like hair and dust. On most Levoit models, it’s a mesh or foam-like material that’s designed to be washable.

Gently pull it out and inspect it. If it’s caked with dust or pet hair, it’s definitely time for a clean. Don’t force it—some pre-filters are held in place with small clips or Velcro strips. If yours feels stuck, double-check the manual or look for hidden tabs.

Step 4: Vacuum the Pre-Filter (Dry Cleaning)

Before washing, I always start with a dry clean. Use your vacuum cleaner’s hose attachment to gently suction off loose dust and debris from both sides of the pre-filter. This removes the bulk of the gunk and makes the next step much more effective.

Hold the filter over a trash can or outside to avoid making a mess. Move the vacuum in slow, overlapping strokes—don’t press too hard, or you might damage the mesh. This step alone can restore a lot of airflow, especially if the filter hasn’t been cleaned in a while.

Step 5: Wash the Pre-Filter (If Washable)

If your pre-filter is labeled as washable (which most Levoit pre-filters are), it’s time for a proper wash. Fill a sink or basin with lukewarm water and add a drop of mild dish soap. Submerge the filter and gently agitate it with your hands. Don’t scrub or twist it—this can tear the delicate material.

Rinse thoroughly under cool running water until all soap is gone. Any residue can attract more dust later, so take your time here. Once clean, shake off excess water and place the filter on a clean towel to air dry completely. Never put it back in the purifier while damp—moisture can lead to mold or damage the unit.

While the pre-filter dries, move on to the other filters. Just remember: only the pre-filter should be washed. The HEPA and carbon filters are not designed for water exposure.

Step 6: Vacuum the HEPA and Carbon Filters

Now, carefully remove the HEPA filter (and carbon filter, if your model has one). These filters are not washable, but they still benefit from gentle vacuuming to remove surface dust.

Use the vacuum’s brush attachment on the lowest suction setting. Gently run it over both sides of the filter, focusing on areas with visible buildup. Avoid pressing too hard—HEPA filters are made of tightly packed fibers that can tear if mishandled.

For carbon filters, be extra gentle. The activated carbon can break down over time, and excessive suction might release fine particles back into the air. A light pass with the vacuum is usually enough to keep it functioning well.

After vacuuming, inspect the filters. If they look yellowed, brittle, or have a strong odor, it’s probably time to replace them. Most Levoit HEPA filters last 6–12 months, depending on usage and air quality.

Step 7: Clean the Interior and Exterior of the Unit

While the filters are out, take a moment to clean the inside of the air purifier. Use a dry or slightly damp cloth to wipe down the interior walls, fan blades, and any accessible surfaces. Avoid getting water near the motor or electrical components.

For the exterior, a microfiber cloth works great. If there’s sticky residue or fingerprints, dampen the cloth with a bit of water and mild soap. Wipe down the front cover, control panel, and base. Let everything dry completely before reassembling.

This step often gets overlooked, but a clean unit runs more efficiently and looks better in your living space. Plus, it prevents dust from re-entering the system once the filters are back in place.

Step 8: Reassemble the Air Purifier

Once all components are dry, it’s time to put everything back together. Start by placing the HEPA and carbon filters back into their slots, making sure they’re seated properly. Then, insert the clean (and completely dry) pre-filter.

Double-check that each filter is in the correct orientation—some have arrows or labels indicating airflow direction. If you took a photo earlier, now’s the time to reference it.

Finally, snap or magnetically reattach the front cover. Give it a gentle press to ensure it’s secure. Plug the unit back in and turn it on. Listen for any unusual noises—if everything sounds normal, you’re good to go!

Pro Tips & Common Mistakes to Avoid

After years of using Levoit air purifiers, I’ve picked up a few tricks—and made my share of mistakes. Here’s what I’ve learned so you don’t have to.

Pro Tip: Clean your pre-filter every 2–4 weeks if you have pets or live in a dusty area. For lighter use, once a month is usually enough. The more you use your purifier, the faster the filters clog.

Warning: Never soak or machine-wash HEPA or carbon filters. Even a small amount of moisture can ruin their effectiveness and void your warranty.

Common Mistake: Putting a damp pre-filter back in the unit. I once made this mistake and noticed a musty smell a few days later. Mold had started growing inside. Always let filters air dry for at least 24 hours.

Pro Tip: Use a filter replacement indicator app or set phone reminders. Levoit’s newer models have built-in filter life indicators, but older ones don’t. Staying on top of replacements ensures peak performance.

Common Mistake: Over-vacuuming the HEPA filter. While it’s tempting to go over it multiple times, excessive suction can damage the fine fibers. One gentle pass is usually sufficient.

Another thing I’ve noticed? People often clean the filters but forget about the air intake and outlet vents. These can collect dust over time, reducing airflow. Use a soft brush or compressed air to clean these areas every few months.

And if you’re unsure whether a filter is washable, always check the manual or Levoit’s website. Different models have different specs, and assuming can lead to costly mistakes.

FAQs About How to Clean Levoit Air Purifier Filters in 2026: Expert Tips

Q: Can I wash the HEPA filter in my Levoit air purifier?
A: No, you should never wash the HEPA filter. It’s made of delicate fibers that can tear or degrade when wet. Instead, gently vacuum the surface to remove dust. If the filter is dirty or smells bad, it’s time to replace it.

Q: How often should I clean the pre-filter?
A: It depends on your environment. If you have pets, smoke, or live in a dusty area, clean the pre-filter every 2–3 weeks. For lighter use, once a month is fine. Regular cleaning extends the life of your HEPA filter and keeps your purifier running efficiently.

Q: My Levoit air purifier is still noisy after cleaning. What’s wrong?
A: Noise can come from a few places. Make sure all filters are properly seated and the cover is securely closed. Also, check if the fan blades are hitting something or if the unit is on an uneven surface. If the problem persists, the motor or internal components might need servicing.

Q: Can I use compressed air to clean the filters?
A: Yes, but with caution. Compressed air can be useful for blowing dust out of tight spaces or the fan area. However, don’t use it directly on the HEPA or carbon filters—it can push debris deeper or damage the fibers. Use low pressure and hold the can upright.

Q: Do I need to replace filters even if they look clean?
A: Yes. Over time, filters lose their ability to trap particles, even if they appear clean. Most Levoit HEPA filters should be replaced every 6–12 months. Check your model’s manual for specific recommendations.

Q: Can I clean my Levoit air purifier with disinfectant wipes?
A: It’s not recommended. Most disinfectant wipes contain chemicals that can damage plastic components or leave residues. Stick to a damp cloth with mild soap for the exterior, and avoid getting moisture near electrical parts.

Q: My air purifier smells musty after cleaning. What should I do?
A: This usually means moisture got trapped inside. Turn off the unit, unplug it, and let it air dry for 24–48 hours in a well-ventilated area. If the smell persists, check if the pre-filter was fully dry before reassembly. In rare cases, mold may have grown—consider replacing the filters if needed.
