How to Clean Levoit Pet Air Purifier in 2026 Easy Steps

Key Takeaways

• Turn off and unplug the purifier before cleaning for safety.
• Vacuum the exterior weekly to remove pet hair and dust buildup.
• Wash the pre-filter monthly with mild soap and let it air dry.
• Replace the HEPA filter every 6–12 months for optimal performance.
• Wipe the interior gently with a dry cloth to avoid moisture damage.
• Clean the air inlet regularly to maintain strong airflow efficiency.

Why This Matters / Understanding the Problem

Let’s face it—your Levoit Pet Air Purifier has been a lifesaver. It’s captured pet dander, tamed sneezes, and made your home feel fresher. But over time, dust, hair, and even mold can sneak into the filters and vents, silently reducing its power.

You might not see it, but a dirty purifier is like a car running on dirty oil. It still moves, but not as well. In fact, cleaning your Levoit Pet Air Purifier in 2026 easy steps isn’t just about hygiene—it’s about performance, longevity, and even your health.

I learned this the hard way. After six months of daily use, my purifier started making a weird grinding noise. Turns out, my cat’s fur had clogged the pre-filter, and the HEPA filter was coated in dust. Cleaning it restored the airflow and silenced the noise. That’s when I realized: regular cleaning isn’t optional. It’s essential.

Whether you’re dealing with shedding fur, seasonal allergies, or just want your air to feel crisp, knowing how to clean Levoit Pet Air Purifier in 2026 easy steps keeps your unit running like new.

What You Need

Before we dive in, let’s gather your cleaning squad. The good news? You probably already have most of these at home.

• Soft microfiber cloths (2–3) – gentle on surfaces, no lint
• Soft-bristled brush (like a clean makeup brush or paintbrush) – perfect for dusting crevices
• Vacuum with brush attachment – for pre-filter and exterior
• Mild dish soap – avoid harsh chemicals
• Clean, dry towel – for drying parts
• Compressed air can (optional) – great for hard-to-reach spots
• Replacement filters (if needed) – check your model for compatible HEPA and pre-filters
• Gloves (optional) – if you’re sensitive to dust or pet hair

Pro tip: Always unplug the purifier before cleaning. Safety first, always.

Step-by-Step Guide to How to Clean Levoit Pet Air Purifier in 2026 Easy Steps

Step 1: Power Down and Unplug the Unit

Start by turning off and unplugging your Levoit Pet Air Purifier. This isn’t just a safety thing—it also lets the internal parts cool down and prevents any accidental startups.

Even if you’re just wiping the outside, unplugging avoids any risk. I once forgot this step and brushed against the power button—my purifier roared to life, startling both me and my cat. Not fun.

Once unplugged, move the unit to a clean, flat surface. A kitchen counter or table works great. Lay down a towel to protect the surface and catch any stray dust.

Step 2: Remove and Inspect the Pre-Filter

The pre-filter is the first line of defense. It catches large particles like pet hair and dust. On most Levoit Pet models (like the Core 300, 400S, or Pet Plus), it’s a mesh screen at the front or side.

To remove it, gently press the release tab or slide it out. Take a close look. If it’s caked with fur or looks gray and grimy, it’s definitely time to clean.

Warning: Don’t wash the pre-filter with water if it’s a foam or carbon type. Only the mesh-style pre-filters are water-safe. Check your manual to confirm.

For mesh pre-filters: rinse under cool running water. Use a drop of mild dish soap and your soft brush to scrub away buildup. Rinse thoroughly and let it air dry completely—at least 4 hours—before reinserting.

For foam or carbon pre-filters: skip water. Instead, use your vacuum’s brush attachment or compressed air to blow out debris. Gently tap it on a hard surface to dislodge dust.

Step 3: Clean the Exterior and Air Inlet/Outlet

Now, let’s give the outside a spa day. Use a dry microfiber cloth to wipe down the top, sides, and base. Pet hair and dust love to cling here.

For stubborn spots, slightly dampen a cloth with water (never spray directly on the unit). Wring it out well—no dripping.

Use the soft brush to clean the air inlet and outlet vents. These are prime spots for fur buildup. I like to use a dry brush first, then a vacuum with the brush attachment for a deeper clean.

For models with touchscreen controls (like the Core 300S), avoid moisture near the panel. Just wipe with a dry microfiber cloth.

Pro tip: If your purifier sits near a litter box or pet bed, wipe the exterior weekly. It saves you deep cleaning time later.

Step 4: Access and Clean the HEPA Filter

The HEPA filter is the heart of your purifier. It traps 99.97% of particles as small as 0.3 microns—including pollen, mold spores, and fine pet dander.

But here’s the catch: you cannot wash a HEPA filter. Water ruins its delicate fiber structure. That said, you can still clean it—gently.

To access it, open the front or side panel (varies by model). Remove the pre-filter first, then slide out the HEPA filter. Hold it up to a light. If it looks dark gray or has visible mold, it’s time to replace it.

For light cleaning: use your vacuum’s brush attachment on the outside (clean side) of the filter. Never vacuum the inside (dirty side). Gently tap it to remove loose dust.

For stubborn debris, use compressed air. Blow from the clean side toward the dirty side. This helps push trapped particles out.

Warning: Never vacuum the inside of the HEPA filter. The suction can damage the fibers and reduce effectiveness.

After cleaning, let the filter sit for 10 minutes to settle any stirred-up dust. Then, reinsert it—clean side facing out.

Step 5: Clean the Carbon Filter (If Applicable)

Some Levoit Pet models (like the Pet Plus) include a carbon filter to remove odors—think litter box, wet dog, or cooking smells.

Like HEPA filters, carbon filters cannot be washed. But you can refresh them by placing them in direct sunlight for 2–4 hours. The UV light helps break down odor-causing compounds.

Before sunbathing, vacuum the surface with the brush attachment to remove dust. After, let it cool completely before reinserting.

If the carbon filter is black, brittle, or smells musty, it’s time to replace it. Most last 3–6 months, depending on use.

Step 6: Reassemble and Reinsert Filters

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

• Reinsert the pre-filter (mesh side facing out)
• Slide in the HEPA filter (clean side out)
• Add the carbon filter (if your model has one)
• Close the front or side panel

Make sure all parts click into place. A loose filter can cause air leaks and reduce efficiency.

Once assembled, plug the purifier back in. Press the power button. Listen for smooth airflow. If it sounds labored or rattles, double-check filter placement.

Step 7: Wipe the Control Panel and Reset the Filter Indicator (If Applicable)

Models with a filter life indicator (like the Core 400S) need a reset after cleaning or replacing filters.

Wipe the control panel with a dry microfiber cloth. For sticky spots, use a cloth dampened with water—never alcohol or cleaners.

To reset the indicator:

1. Press and hold the “Filter Reset” button (usually for 3–5 seconds)
2. Wait for the indicator light to turn green or reset

This tells your purifier the filters are fresh. Without resetting, it might keep nagging you to replace them—even if they’re clean.

Step 8: Run a Test Cycle

After cleaning, let your purifier run on medium or high for 15–30 minutes. This helps clear any loose dust stirred up during cleaning.

Place it in a central room. Notice the airflow—it should feel stronger and quieter than before.

If you still hear noise or feel weak airflow, recheck filter placement or consider replacing the HEPA filter.

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve learned a few hard-earned lessons about how to clean Levoit Pet Air Purifier in 2026 easy steps. Here’s what you need to know:

Pro Tip 1: Clean the pre-filter every 2–4 weeks. It’s the easiest step and makes a huge difference. I keep a reminder on my phone.

Pro Tip 2: Label your filters. Write the date on the HEPA and carbon filters with a marker. It helps track when they’re due for replacement.

Pro Tip 3: Use a lint roller on the exterior. If you have a shedding pet, roll the sides and top weekly. It’s faster than wiping and removes fur instantly.

Common Mistake 1: Washing HEPA or carbon filters. I did this once, thinking a good rinse would help. Big mistake. The HEPA filter never worked the same. Save water for the pre-filter only.

Common Mistake 2: Reinserting wet filters. Even a damp pre-filter can mold. Always air dry completely—no shortcuts.

Common Mistake 3: Skipping the vacuum step. Brushing alone won’t get deep dust. Vacuuming the pre-filter and exterior removes buildup before it reaches the HEPA.

Pro Tip 4: Clean in a well-ventilated area. Dust and pet hair can spread. I clean mine near an open window or in the garage.

Pro Tip 5: Keep spare filters on hand. When one’s dirty, swap in a new one. Clean the old one, let it dry, and store it. This way, you’re never without clean air.

FAQs About How to Clean Levoit Pet Air Purifier in 2026 Easy Steps

How often should I clean my Levoit Pet Air Purifier?

Clean the pre-filter every 2–4 weeks, especially if you have shedding pets. The exterior can be wiped weekly. Deep clean the HEPA and carbon filters every 3–6 months—or when airflow feels weak.

I clean mine every month, but if my cat is in a shedding phase, I do the pre-filter every 2 weeks. It’s a small effort for big rewards.

Can I wash the HEPA filter?

No. Water destroys the HEPA filter’s structure. You can only vacuum the outside or use compressed air. If it’s dark, musty, or damaged, replace it.

Think of it like a paper towel—wet it, and it falls apart. HEPA filters are the same.

My purifier smells musty after cleaning. What’s wrong?

This usually means mold or moisture in the filters. If the pre-filter wasn’t dried completely, mold can grow. Or, the carbon filter might be old and saturated.

Replace any musty filters. Run the purifier with fresh filters and a fan in the room to dry the system.

Can I use compressed air on the inside of the purifier?

Yes—but gently. Use short bursts on the fan blades and internal vents. Avoid spraying directly at the filters. I use a can with a straw nozzle for precision.

Never use a leaf blower or high-pressure air. It can damage the motor.

How do I know when to replace the filters?

Check these signs:

• HEPA filter is dark gray or black
• Airflow is weak even after cleaning
• Purifier makes grinding or rattling noises
• Carbon filter smells musty or ineffective
• Filter indicator light is red (on smart models)

Most HEPA filters last 6–12 months. Carbon filters last 3–6 months. Pets and allergies shorten their life.

Is it safe to clean the purifier while it’s on?

Absolutely not. Always unplug it first. Cleaning while powered risks electric shock or motor damage. I know it’s tempting to “just wipe it quick,” but it’s not worth the risk.

Can I use disinfectant wipes on the exterior?

No. Alcohol and disinfectants can damage the plastic and control panel. Stick to dry or slightly damp microfiber cloths. If you must disinfect, use a cloth with a tiny amount of soapy water—never directly on the unit.

Final Thoughts

Cleaning your Levoit Pet Air Purifier doesn’t have to be a chore. With these how to clean Levoit Pet Air Purifier in 2026 easy steps, it’s a quick, rewarding routine that keeps your air fresh and your purifier happy.

Remember: the pre-filter is your best friend. Clean it often. Treat the HEPA and carbon filters with care. And never skip the drying step—mold is a silent enemy.

I clean mine every month, and it takes about 20 minutes. That’s less time than a coffee run, and the payoff is cleaner air, fewer allergies, and a purifier that lasts years.

So grab your cloth, vacuum, and brush. Give your purifier the love it deserves. Your lungs—and your pets—will thank you.

And hey, if you’re ever in doubt? Just unplug, breathe, and start with the pre-filter. One step at a time. You’ve got this.
