How to Clean Alen Air Purifier Filters in 2026: Easy Steps

Key Takeaways

• Power off and unplug your Alen purifier before cleaning for safety.
• Vacuum pre-filters monthly to extend HEPA filter lifespan efficiently.
• Rinse washable filters gently with cool water; avoid harsh detergents.
• Air-dry fully before reinstalling to prevent mold and damage.
• Replace HEPA filters annually or as needed based on air quality.
• Use the Alen app to track filter status and cleaning schedules.

Why This Matters / Understanding the Problem

Let’s be real—your Alen air purifier works hard every single day. It’s quietly pulling dust, pet dander, pollen, and even cooking fumes out of your home’s air so you can breathe easier. But here’s the thing: if you don’t clean or maintain those filters regularly, all that hard work starts to backfire.

I learned this the hard way last winter. My apartment started smelling musty, and I couldn’t figure out why—until I opened up my Alen purifier and saw the filter clogged with grime. It wasn’t just inefficient; it was actually recirculating dirty air! That’s when I realized how important it is to know how to clean Alen air purifier filters in 2026 easy steps. Not only does regular cleaning boost performance, but it also extends the life of your unit and saves you money on premature replacements.

Whether you’ve got an Alen BreatheSmart, Paralda, or any other model, proper filter care is non-negotiable. In this guide, I’ll walk you through everything you need—from tools to timing—so you can keep your purifier running like new, year after year.

What You Need

Before we dive into the actual cleaning, let’s gather what you’ll need. Don’t worry—it’s nothing fancy or expensive. Most of these items are probably already in your cleaning closet.

• Soft-bristle brush (an old toothbrush works great!)
• Vacuum cleaner with a hose attachment
• Mild dish soap (unscented and free of harsh chemicals)
• Clean, lint-free cloth or microfiber towel
• Lukewarm water
• Optional: Compressed air canister (for stubborn dust in tight spaces)
• Replacement pre-filter (if needed) – some Alen models have washable pre-filters, others don’t

Pro tip: Always check your user manual first! Alen designs different models with varying filter types—some have washable pre-filters, while others require replacement. Knowing your specific model saves you from accidentally damaging a non-washable component.

Step-by-Step Guide to How to Clean Alen Air Purifier Filters in 2026 Easy Steps

Step 1: Turn Off and Unplug Your Purifier

Safety first, always. Before you touch anything inside your Alen unit, make sure it’s completely powered off and unplugged from the wall outlet. I learned this lesson after nearly giving myself a shock reaching into a unit I thought was “off” but still plugged in.

This simple step protects both you and your device. Plus, it gives the internal components time to cool down if the purifier has been running recently.

Step 2: Remove the Front Panel and Access the Filters

Most Alen purifiers have a front panel that snaps off easily—no tools required. Gently pull the panel toward you until it releases. On some models, like the BreatheSmart series, you’ll hear a soft click when it’s ready to come off.

Once the panel is off, you’ll see the filter stack. Typically, there’s a pre-filter (the outermost layer that catches large particles), followed by the HEPA filter, and sometimes a carbon filter underneath. Take note of the order—you’ll want to reassemble them correctly later.

If you’re unsure which filter is which, snap a quick photo with your phone before removing anything. It’ll save you headaches when putting it back together.

Step 3: Vacuum the Pre-Filter

The pre-filter is your first line of defense—and usually the dirtiest part. Use your vacuum’s hose attachment to gently suction away dust, hair, and debris from both sides of the pre-filter. Hold the filter firmly so it doesn’t get sucked into the vacuum!

For Alen models with a washable pre-filter (like many BreatheSmart units), this step is crucial between deep cleans. Even if you plan to wash it later, vacuuming first removes loose gunk so you’re not rinsing a muddy mess.

Warning: Never vacuum the HEPA filter directly unless your manual explicitly says it’s safe. Most HEPA filters are delicate and can tear or lose efficiency if vacuumed aggressively.

Step 4: Wash the Washable Pre-Filter (If Applicable)

If your Alen model includes a washable pre-filter (check the label or manual!), now’s the time to give it a proper bath. Rinse it under lukewarm water—never hot! Hot water can warp or damage the mesh.

Add a drop of mild dish soap if there’s stubborn grease or odor (common in kitchens or pet-heavy homes). Gently scrub with your soft-bristle brush, focusing on stained areas. Then rinse thoroughly until no soap remains.

Shake off excess water and lay the filter flat on a clean towel to air-dry completely—never reinstall a damp filter. Moisture can promote mold growth and ruin your purifier’s electronics. I usually let mine dry overnight just to be safe.

Step 5: Wipe Down the Interior and Exterior

While the pre-filter dries, take a moment to clean the inside of your purifier. Use a dry or slightly damp microfiber cloth to wipe down the fan blades, housing, and any accessible surfaces. Avoid spraying water directly into the unit—dampen the cloth instead.

Don’t forget the exterior! Dust loves to settle on the front grille and control panel. A quick wipe keeps your purifier looking fresh and ensures airflow isn’t blocked by external buildup.

Step 6: Inspect the HEPA and Carbon Filters

Now, take a close look at your HEPA filter. If it’s visibly discolored (gray or brown instead of white/light gray), smells musty, or has been in use for 6–12 months (depending on usage), it’s likely time for a replacement—not a cleaning.

Most HEPA filters in Alen purifiers are not washable. Attempting to clean them with water or compressed air can destroy their microscopic structure, reducing their ability to trap allergens. Same goes for carbon filters—they’re designed for absorption, not rinsing.

However, if your HEPA filter looks relatively clean and you’re within the recommended usage window, you can lightly vacuum the outside surface (the side facing the room) to remove surface dust. Do this gently—no scrubbing!

Step 7: Reassemble and Restart

Once everything is dry and inspected, carefully place the filters back in their original order: pre-filter first, then HEPA, then carbon (if present). Make sure each filter sits snugly in its slot—no gaps or misalignments.

Snap the front panel back into place until it clicks securely. Plug your purifier back in and turn it on. Listen for unusual noises—if something sounds off, double-check that all components are seated correctly.

Run your purifier on low for about 30 minutes to ensure proper airflow before returning to your usual settings.

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve made my share of mistakes—and learned a ton from them. Here’s what I wish I’d known sooner:

• Don’t wait until it smells bad. By then, your filter is likely overdue. Set a calendar reminder every 2–3 months for pre-filter cleaning and every 6–12 months for HEPA inspection.
• Never use bleach or harsh cleaners. They can degrade filter materials and leave toxic residues in your air.
• Avoid compressed air on HEPA filters. It might seem efficient, but high-pressure air can puncture the fine fibers.
• Keep spare pre-filters on hand. If yours gets damaged during cleaning, you won’t have to run your purifier unfiltered.
• Track your usage. If you have pets, live in a dusty area, or cook frequently, you’ll need to clean more often than someone in a low-pollution environment.

Personal Insight: I used to think “cleaning” meant just wiping the outside. But once I started following the full how to clean Alen air purifier filters in 2026 easy steps routine, my allergy symptoms dropped dramatically—and my energy bills went down because the unit didn’t have to work as hard!

FAQs About How to Clean Alen Air Purifier Filters in 2026 Easy Steps

Q: Can I wash my Alen HEPA filter?
A: Generally, no. Most Alen HEPA filters are not washable. Check your model’s manual—if it doesn’t say “washable,” assume it’s not. Washing can ruin the filter’s ability to capture tiny particles like smoke or bacteria.

Q: How often should I clean the pre-filter?
A: Every 2–4 weeks if you have pets or live in a dusty area. Otherwise, every 6–8 weeks is usually sufficient. If you notice reduced airflow or louder fan noise, it’s time for a clean.

Q: What if my pre-filter is torn or damaged?
A: Replace it immediately. A torn pre-filter lets large particles bypass into the HEPA filter, shortening its lifespan. Alen sells genuine replacement pre-filters online—just search your model number.

Q: My purifier still smells after cleaning. What now?
A: The odor might be coming from the carbon filter, which absorbs smells over time and eventually saturates. Replace the carbon filter (usually every 6–12 months) or consider adding a fresh bowl of baking soda nearby as a temporary fix.

Q: Can I use a wet cloth to clean the inside of the purifier?
A: Only if the cloth is barely damp—and never spray liquid directly into the unit. Excess moisture can damage the motor or electronics. Always unplug first!

Q: Is it okay to run my purifier without the pre-filter?
A: Technically yes, but not recommended. The pre-filter protects the more expensive HEPA filter from large debris. Skipping it means your HEPA will clog faster and need replacement sooner.

Q: Do I need special tools to clean Alen filters?
A: Nope! Just basic household items: vacuum, brush, soap, and water. No special kits or proprietary cleaners required—Alen designs their filters for easy DIY maintenance.
