How to Clean Bissell Air Purifier Filter in 2026: Easy Guide

Key Takeaways

• Turn off and unplug the purifier before cleaning for safety.
• Remove the filter carefully to avoid damaging internal components.
• Rinse with cold water—never use soap or harsh chemicals.
• Dry completely before reuse to prevent mold and odors.
• Clean every 3–6 months based on usage and air quality.
• Replace if damaged or discolored even if cleaning appears effective.

Why This Matters – And Why You’re Probably Overlooking It

Let me tell you a quick story. Last winter, I noticed my allergies acting up more than usual—even though I’d just replaced the filters in my home’s HVAC system. I was sneezing, my eyes were itchy, and I couldn’t figure out why. Then one evening, while dusting near my Bissell air purifier, I caught a whiff of something… funky. Like stale popcorn mixed with wet dog. That’s when it hit me: I hadn’t cleaned the filter in over six months.

Turns out, a dirty air purifier filter doesn’t just stop cleaning the air—it can actually make indoor air quality worse. Dust, pet dander, mold spores, and even bacteria can build up and get recirculated back into your living space. And if you’re like most people (including me, once upon a time), you probably bought your Bissell air purifier thinking it was “set it and forget it.” Spoiler alert: it’s not.

That’s exactly why knowing how to clean Bissell air purifier filter in 2026 easy guide isn’t just helpful—it’s essential for keeping your home truly healthy. Whether you’ve got pets, live in a dusty climate, or just want to breathe easier, regular maintenance makes all the difference. Plus, cleaning your filter properly can extend its life, save you money on replacements, and keep your purifier running efficiently.

In this guide, I’ll walk you through everything you need—from tools to timing—to clean your Bissell air purifier filter safely and effectively. No jargon, no fluff—just real, practical steps based on what actually works.

What You Need

Before we dive in, let’s gather our supplies. The good news? You likely already have most of these at home. Here’s your quick checklist:

• Soft-bristle brush (an old toothbrush works great)
• Mild dish soap (unscented and non-abrasive)
• Clean, lukewarm water
• Microfiber cloth or lint-free towel
• Vacuum cleaner with a hose attachment (optional but helpful)
• Timer or calendar reminder (yes, really—consistency is key!)

A few notes before we start:
– Never use harsh chemicals like bleach, ammonia, or aerosol sprays. They can damage the filter media and leave toxic residues.
– If your model uses a permanent washable filter (like many Bissell TrueFilter models), you’re in luck—you can clean it repeatedly. But if it has a disposable HEPA filter, cleaning isn’t recommended; you’ll need to replace it instead. Always check your user manual to confirm your filter type.

Now that we’re prepped, let’s get into the nitty-gritty.

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

Step 1: Turn Off and Unplug Your Air Purifier

Safety first—always! Before you even think about touching the filter, make sure your Bissell air purifier is completely powered off and unplugged from the wall outlet. This isn’t just about avoiding electric shocks (though that’s important too); it also prevents accidental startup while you’re handling internal components.

I learned this the hard way once when I nudged the power button with my elbow while reaching inside the unit. The sudden whirring startled me so much I dropped the filter—and cracked the housing. Don’t be me. Take the extra 10 seconds to unplug it.

Once it’s off, give the unit a moment to cool down if it’s been running recently. Warm filters can warp or become brittle, making them harder to clean without damage.

Step 2: Locate and Remove the Filter

Now comes the fun part: finding the filter. On most Bissell air purifiers, the filter is housed behind a front or side panel. Look for a latch, clip, or simple snap-on cover—there’s usually no screwdriver needed.

Gently press the release tabs (they’re often marked with arrows or icons) and swing the panel open. Inside, you’ll see the filter—typically a rectangular cartridge with a mesh or pleated design. Some models have multiple layers (pre-filter, carbon filter, HEPA), so take note of how they’re stacked as you remove them. A quick photo on your phone can help you remember the order later.

Pro tip: If you’re unsure which model you have, check the label on the back or bottom of the unit. Bissell’s website has a handy model lookup tool that tells you exactly what kind of filter your purifier uses.

Once removed, inspect the filter. If it’s visibly caked with dust, fur, or discoloration, it’s definitely time for a deep clean. Even if it looks okay, routine cleaning every 2–3 months is ideal—especially if you have pets or live in a high-pollen area.

Step 3: Vacuum Loose Debris (Optional but Recommended)

Before washing, use your vacuum’s hose attachment to gently suction away surface dust and hair. Hold the filter over a trash can and run the vacuum along both sides—front and back. This step removes the bulk of debris and prevents clogging your sink or shower drain later.

Don’t press too hard—you’re not sanding wood here! Just light, sweeping motions. If you don’t have a vacuum handy, a soft brush (like that old toothbrush) works too, though it’ll take a bit longer.

This pre-cleaning step is especially useful for homes with shedding pets. I have two golden retrievers, and trust me—without this step, my sink would be a fur-filled disaster zone.

Step 4: Rinse with Lukewarm Water

Now for the main event: rinsing. Fill a clean basin, sink, or bathtub with lukewarm water—never hot! Hot water can damage the filter’s delicate fibers or adhesive seals.

Hold the filter under the water and gently swish it around. Let the water flow through both sides to flush out trapped particles. Avoid twisting, wringing, or scrubbing aggressively—you could tear the filter media.

If your filter has a foam pre-filter (common on Bissell models like the Air320 or Pro+, rinse it separately. These foam layers are more durable and can handle a bit more agitation, but still avoid harsh squeezing.

Rinse until the water runs clear. This might take a minute or two, especially if the filter was really dirty. Patience pays off here—rushing can leave behind grime that reduces airflow and efficiency.

Step 5: Wash with Mild Soap (If Needed)

For stubborn odors or greasy buildup (think cooking fumes or pet smells), a drop of mild dish soap can help. Add just a few drops to your basin of lukewarm water and swirl the filter gently for 30–60 seconds.

Again, less is more. Too much soap can leave a residue that attracts more dust later. And never use scented or antibacterial soaps—they often contain additives that degrade filter materials over time.

After washing, rinse thoroughly under clean water to remove all soap traces. Any leftover suds can clog the filter pores and reduce performance.

Step 6: Air-Dry Completely

This step is non-negotiable: your filter must be 100% dry before reinstalling. Moisture trapped inside can lead to mold growth, musty odors, or even electrical damage if it reaches internal components.

Place the filter on a clean towel in a well-ventilated area—away from direct sunlight or heat sources (like radiators). Sunlight can degrade certain filter materials, and heat can warp them.

Let it air-dry for at least 24 hours. I usually set a reminder on my phone: “Check filter dryness – tomorrow AM.” If you’re in a humid climate, you might need longer. Never speed up drying with a hairdryer or oven—it’s not worth the risk.

While waiting, wipe down the inside of your air purifier with a dry microfiber cloth to remove any dust that settled during filter removal.

Step 7: Reinstall and Reset

Once the filter is bone-dry, carefully place it back into the unit in the correct orientation. Most Bissell filters have arrows or labels indicating airflow direction—make sure those point toward the fan.

Close the panel securely and plug the purifier back in. Turn it on and listen for smooth operation. If you hear unusual noises or reduced airflow, double-check that the filter is seated properly.

Many newer Bissell models have a filter reset button or indicator light. After cleaning, press and hold the reset button (usually for 3–5 seconds) to clear the “replace filter” alert. This ensures your purifier accurately tracks future maintenance needs.

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve made my fair share of mistakes—and learned some hard-earned lessons. Here’s what I wish someone had told me sooner:

Pro Tip: Set a recurring calendar reminder every 8–12 weeks to check your filter. Consistency beats perfection. Even if it looks clean, airflow decreases over time due to microscopic particle buildup.

Warning: Never soak a HEPA filter in water—even if it’s labeled “washable.” True HEPA filters are made of fragile glass fibers that lose efficiency when wet. Only clean the outer pre-filter if your model has one.

Common Mistake: Assuming all Bissell filters are the same. Models vary widely—some use reusable foam filters, others have disposable cartridges. Always verify your filter type before cleaning. Cleaning a non-washable filter voids your warranty and ruins performance.

Another thing I’ve noticed? People often clean the filter but forget the exterior vents and fan blades. Dust builds up there too! Every few months, use a damp cloth to wipe the intake and outlet grilles, and gently clean the fan with a soft brush (while unplugged, of course).

And finally—don’t wait for your purifier to smell bad or sound strained. By then, it’s already working overtime. Regular cleaning keeps it efficient, quiet, and effective.

FAQs About How to Clean Bissell Air Purifier Filter in 2026 Easy Guide

Q: How often should I clean my Bissell air purifier filter?
A: For washable filters, every 2–3 months is ideal. If you have pets, smoke indoors, or live in a dusty area, check it monthly. Disposable filters should be replaced every 6–12 months—cleaning isn’t safe or effective for those.

Q: Can I clean a HEPA filter in my Bissell purifier?
A: Only if your manual explicitly says it’s washable. Most Bissell HEPA filters are not meant to be washed—they’re designed for replacement. Washing them damages the fine fibers and reduces filtration efficiency.

Q: My filter still smells after cleaning. What should I do?

A: Lingering odors often mean mold or bacterial growth. If rinsing and air-drying don’t help, it’s time to replace the filter. For future prevention, ensure it dries completely within 24 hours and consider using an activated carbon filter layer if your model supports it.

Q: Is it okay to use vinegar to clean the filter?
A: I wouldn’t recommend it. While vinegar is natural, its acidity can degrade certain filter adhesives and materials over time. Stick to mild soap and water for safest results.

Q: Will cleaning my filter improve air quality right away?
A: Absolutely! A clean filter restores optimal airflow and capture efficiency. You might notice less dust on surfaces, fewer allergy symptoms, and a quieter-running unit within hours of reinstalling.

Q: What if I lose my user manual?
A: No worries! Visit Bissell’s official support page and enter your model number. They provide free digital manuals with detailed filter care instructions for every product.

Q: Can I run my purifier without the filter?
A: Never! Running the unit without a filter exposes the internal motor to dust and debris, which can cause permanent damage. Always reinstall the filter—even if it’s just been cleaned—before turning it back on.
