How to Clean a Levoit Air Purifier Filter in 2026

Let’s be honest—your Levoit air purifier has been quietly working overtime, especially during allergy season or when you’ve had guests over with pets. You’ve probably noticed it humming along in the corner of your bedroom or living room, doing its job without much fanfare. But have you ever stopped to think about what’s happening inside that sleek white machine? Behind the scenes, your air purifier’s filter is catching dust, pollen, pet dander, and even microscopic pollutants, all while trying to keep your indoor air fresh and breathable.

Now, here’s the thing: even the best air purifiers need a little TLC. And by “a little TLC,” I mean regular cleaning—especially the filter. If you’ve been using your Levoit air purifier for a few months (or longer), chances are that filter isn’t as effective as it once was. A dirty filter doesn’t just reduce performance—it can actually start circulating stale or contaminated air, which defeats the whole purpose of having a purifier in the first place. So, whether you’re a first-time owner or a seasoned user looking to refresh your maintenance routine, this guide will walk you through exactly how to clean a Levoit air purifier filter in 2026—step by step, with real-world tips and zero fluff.

Why Cleaning Your Levoit Air Purifier Filter Matters

It Keeps Your Air Truly Clean

Think of your air purifier filter like the lungs of your home. When it’s clogged with dust and debris, it can’t “breathe” properly. That means it can’t trap new pollutants effectively. Over time, a dirty filter becomes less efficient, and in some cases, it may even release trapped particles back into the air—especially if the unit is turned on at high speed. Cleaning your filter regularly ensures that your Levoit continues to deliver on its promise: cleaner, fresher air.

It Extends the Life of Your Filter and Unit

Levoit filters aren’t cheap—especially the HEPA and activated carbon models. Replacing them too often can add up quickly. But with proper cleaning and maintenance, you can significantly extend their lifespan. For example, the pre-filter (which captures larger particles like hair and lint) is often washable. Cleaning it every 2–4 weeks can delay the need to replace the main HEPA filter by several months. That’s money saved and less waste generated.

It Improves Energy Efficiency and Performance

A clogged filter forces your air purifier to work harder to pull air through. This increases energy consumption and can lead to louder fan noise. In fact, a study by the U.S. Department of Energy found that HVAC systems (and by extension, air purifiers) can use up to 15% more energy when filters are dirty. By cleaning your Levoit filter, you’re not just improving air quality—you’re also helping your machine run more efficiently and quietly.

It Prevents Mold and Bacteria Growth

This one might surprise you: a dirty, damp filter can become a breeding ground for mold and bacteria—especially in humid climates or during rainy seasons. If you’ve ever noticed a musty smell coming from your purifier, that’s a red flag. Regular cleaning helps prevent microbial growth, keeping your indoor environment healthier for you and your family.

Understanding Your Levoit Air Purifier Filter System

Types of Filters in Levoit Purifiers

Before you start cleaning, it’s important to know what kind of filter system your Levoit model uses. Most Levoit air purifiers feature a 3-stage filtration system:

Pre-Filter: Captures large particles like pet hair, dust, and lint. This is usually the outermost layer and is often washable.
True HEPA Filter: Removes 99.97% of particles as small as 0.3 microns, including pollen, mold spores, and smoke.
Activated Carbon Filter: Absorbs odors, VOCs (volatile organic compounds), and gases from cooking, pets, or cleaning products.

Some newer models, like the Levoit Core 400S or Vital 200S, also include a washable pre-filter and a permanent HEPA filter (in select versions), which can be cleaned rather than replaced. Always check your user manual to confirm which filters are washable and which are not.

Which Filters Can You Clean?

Here’s a quick rule of thumb:

Washable: Pre-filter (in most models), some permanent HEPA filters (check model specs).
Not Washable: Standard True HEPA filters, activated carbon filters (these are typically replaceable only).

For example, the Levoit LV-H132 uses a non-washable HEPA filter, while the Levoit Core 300 has a washable pre-filter and a replaceable HEPA filter. Always refer to your model’s manual to avoid damaging non-washable components.

How Often Should You Clean?

Cleaning frequency depends on usage and environment:

High-traffic homes (pets, kids, smokers): Clean the pre-filter every 2 weeks.
Moderate use (apartment, no pets): Every 3–4 weeks.
Low use (guest room, seasonal): Every 6–8 weeks.

Levoit’s smart models (like the Core 400S) often have a filter life indicator that alerts you when maintenance is due. But don’t rely solely on the light—trust your eyes and nose. If the filter looks gray or smells musty, it’s time to clean.

Step-by-Step Guide: How to Clean a Levoit Air Purifier Filter

Step 1: Turn Off and Unplug the Unit

Safety first! Always turn off your Levoit air purifier and unplug it from the power source before removing any filters. This prevents accidental startup and protects you from electrical hazards. It’s a simple step, but one that’s easy to skip when you’re in a hurry.

Step 2: Remove the Front Cover and Filters

Most Levoit models have a front cover that snaps off easily. Gently pull it away from the unit—there’s usually a small latch or groove near the bottom. Once the cover is off, you’ll see the pre-filter, followed by the HEPA and carbon filters (if applicable).

Carefully remove each filter, noting their order. Take a photo with your phone if you’re unsure—this helps when reassembling. Place the filters on a clean, flat surface like a towel or tray to avoid contamination.

Step 3: Clean the Pre-Filter (Washable Models Only)

If your model has a washable pre-filter (common in Core and Vital series), this is where the real cleaning happens. Here’s how:

Use a soft-bristle brush or vacuum with a brush attachment to remove loose dust and hair.
Rinse the filter under lukewarm water. Avoid hot water—it can damage the mesh.
Gently scrub with your hands if needed, but don’t use soap or detergents—they can leave residues that affect airflow.
Shake off excess water and let the filter air-dry completely—this can take 6–12 hours. Never reinstall a damp filter.

Pro Tip: If you’re short on time, use a handheld vacuum to clean the pre-filter between full washes. This keeps it functional longer.

Step 4: Vacuum the HEPA Filter (If Washable)

Some Levoit models, like the Core 300S, feature a washable HEPA filter. If yours is one of them:

Use a vacuum with a soft brush attachment to gently remove surface dust.
Do not rinse or soak the HEPA filter unless the manual explicitly says it’s safe. Most HEPA filters are not designed to get wet.
If your model allows washing, rinse lightly under cold water and air-dry for at least 24 hours.

Warning: Never wash a non-washable HEPA filter. Doing so can destroy its delicate fiber structure, rendering it useless.

Step 5: Wipe Down the Carbon Filter (If Applicable)

Activated carbon filters are not washable and should never be exposed to water. However, you can extend their life by:

Vacuuming the surface gently to remove dust buildup.
Placing the filter in direct sunlight for 2–3 hours to help “recharge” the carbon (this works best in dry, sunny climates).

This won’t restore full effectiveness, but it can reduce odors and buy you a little extra time before replacement.

Step 6: Clean the Interior and Exterior of the Unit

While the filters are out, take the opportunity to clean the inside of the purifier:

Use a dry or slightly damp microfiber cloth to wipe down the fan blades, housing, and air intake vents.
Never spray water directly into the unit—moisture can damage the motor.
For stubborn dust, use a can of compressed air (like those used for electronics) to blow out crevices.

Also, wipe the exterior with a damp cloth and mild cleaner. A clean machine looks better and performs better.

Step 7: Reassemble and Reset the Filter Indicator

Once everything is dry and clean, carefully reinstall the filters in the correct order. Snap the front cover back into place and plug in the unit.

If your Levoit has a filter life indicator (common in smart models), reset it after cleaning. This ensures accurate tracking. For example, on the Core 400S, hold the “Filter” button for 3 seconds to reset the timer.

Common Mistakes to Avoid When Cleaning Your Levoit Filter

Using Water on Non-Washable Filters

This is the #1 mistake I see people make. Just because a filter looks dirty doesn’t mean it’s washable. Pouring water on a standard HEPA filter can ruin its electrostatic charge and fiber integrity. Always check your manual first.

Reinstalling a Damp Filter

A damp filter can promote mold growth and damage the motor. Even if it feels “mostly dry,” give it extra time. I once made the mistake of reinstalling a slightly damp pre-filter—within a week, my purifier started smelling like mildew. Lesson learned.

Using Harsh Cleaners or Soaps

Avoid dish soap, bleach, or disinfectants. These can leave chemical residues that get released into your air when the purifier runs. Stick to water and gentle brushing.

Ignoring the Filter Life Indicator

Even if you clean the pre-filter regularly, the HEPA and carbon filters degrade over time. The indicator light is there for a reason. Don’t wait until your air smells stale or your allergies flare up—replace filters as recommended (usually every 6–12 months).

Overcleaning the HEPA Filter

Some users think more cleaning = better performance. But excessive vacuuming can damage the delicate fibers. Clean only when necessary and use a soft touch.

Pro Tips for Maintaining Your Levoit Air Purifier in 2026

Create a Cleaning Schedule

Set a monthly reminder on your phone or calendar. For example:

First Sunday of the month: Clean pre-filter.
Every 3 months: Deep clean interior and check filter condition.
Every 6–12 months: Replace HEPA and carbon filters (or as indicated).

Consistency is key. A little effort each month prevents big problems later.

Use a Filter Cover or Pre-Filter Protector

If you live in a dusty area or have shedding pets, consider using an additional mesh pre-filter cover. These inexpensive accessories catch hair and large debris before they reach the main filter, reducing cleaning frequency.

Monitor Air Quality with a Smart Sensor

Levoit’s smart models come with built-in air quality sensors. Use the app to track PM2.5 levels and filter performance. If the air quality drops suddenly, it might be time for a cleaning—even if the indicator hasn’t lit up yet.

Store Filters Properly When Not in Use

If you’re storing your purifier (e.g., during summer in a seasonal home), remove the filters, seal them in a plastic bag, and store in a cool, dry place. This prevents moisture and pests from damaging them.

Upgrade to a Washable HEPA Model (If Possible)

If you’re due for a new purifier, consider models with washable HEPA filters, like the Levoit Core 300S or Vital 100S. These can save you hundreds in replacement costs over time.
