"For YEARS I've had a 'clear the crud' cough every morning. ZERO coughing since putting these on our fans."
Brittany M. verified Verified Buyer

How It Works

Your ceiling fan moves 7x more air than standalone purifiers. Barnakl's activated coconut shell carbon filters stick to the top of each blade and trap 250+ pollutants as your fan runs.

The porous carbon surface attracts VOCs, allergens, mold spores, and odors like a magnet. You'll see the difference as filters visibly capture dirt and gain 15–30% weight from trapped contaminants.

Installation

  1. Peel the backing off each adhesive filter panel
  2. Stick one filter to the top of each fan blade
  3. Turn on your fan and let it work
  4. Replace every 60 days for continuous clean air

Takes under 60 seconds!

Benefits

  • Better Sleep: Cleaner air promotes deeper, more restorative rest
  • Reduced Health Risks: Lower long-term exposure to pollutants linked to asthma, heart disease, and lung cancer
  • Allergy Relief: Fewer allergens mean less sneezing, congestion, and itchy eyes
  • Fresher Home: Eliminates pet, cooking, and household odors naturally
  • Mental Clarity: Improved air quality supports sharper focus and cognitive function
  • Invisible & Silent: Works completely out of sight with zero noise
  • 10x More Effective: Cleans more air than a standalone purifier, at a fraction of the cost

FAQ

Does Barnakl have a smell?
Nope! The filters are completely odorless and actually eliminate odors in your home

Do I have to get rid of my air purifier if I want to use Barnakl?
Absolutely not! Barnakl works great on its own, but it also boosts the effectiveness of existing air purifiers and can extend their longevity by sharing the workload.

How does an activated carbon filter actually work?
Barnakl's activated coconut shell carbon traps contaminants in its porous surface. You'll see an increase in weight of 15–30% after using it — that's the chemicals and gases it's captured. By sitting on top of your ceiling fan, it maximizes air contact to trap far more pollutants than standalone purifiers.

How often do Barnakl filters need to be changed?
Every 60 days. Subscribe and save 25% on auto-deliveries so you're always ready when it's time to refresh.

Does it impact the balance of the fan?
Nope! Each filter only weighs 6 grams and doesn't imbalance the rotation. We also tested the airflow performance and nothing was affected.

Will the adhesive on the filter damage my fan blades?
No. Just peel the filter away from the Velcro base. If you need to remove the adhesive, peel it off slowly and it won't damage the blade surface.

Did you know?

Unfiltered Ceiling Fans Make Dirty Air... Dirtier

With Filter

Without Filter

Every whir spreads dust, contaminants, and allergens all over your home.

Dusting and air purifiers only push the problem around. For cleaner air, you must remove airborne particles once and for all.

Dust Redistribution

Rotating fan blades lift dust particles back into the air.

Allergen Recirculation

Ceiling fans continuously cycle pollen, dander, and mold spores.

Overnight Exposure

8 hours inhaling dirty air into your lungs, every single night.

And are you sleeping with your fan on?

Ceiling fans can push PM2.5 above outdoor levels for hours at a time, making sleep your highest daily exposure to pollution.

Unfiltered Nightly Exposure:
8 Hrs Adults
10-12 Hrs Children

Here's What You've Been Breathing In

Indoor air is up to 5x more polluted than outside. The coughing, the allergies, the brain fog — you're probably breathing the cause right now.

And you'd never know. You can't see them, feel them, or smell them until the damage is done.

86% of indoor air harm comes from particles and Barnakl is the only filter that removes them.

How Barnakl Works

Filters 7x MORE Air Than a $600 Purifier

*Conservative comparison. Fans move 3,000–10,000 CFM; purifiers 20–450 CFM.

Air Purifier

Barnakl Filters

Because every cubic foot goes through the filter, not around it.

Attach your Barnakl filter directly to your fan blades. Every
rotation forces air through the filter – not past it.

And every particle gets the full filtration treatment.

Activated Coconut Shell Fibers

Up to 1,200 m²/g surface area for maximum particle interception.

Barnakl Filters

How does Barnakl compare to HEPA?

Wondering about the difference between Barnakl and HEPA filters?

HEPA

Captures the most particles it can in a single pass — cleaning the air that flows directly through the unit.

Barnakl

Captures particles again and again, cleaning the whole room as your ceiling fan keeps the air moving through it.

Barnakl is independently lab-tested to pull airborne particles, VOCs, mold spores, and microplastics out of the air in your room. It doesn't work the way HEPA does — it takes a different path, riding the ceiling fan you already own to keep cleaning the whole room, pass after pass.

Inside the Filter

Activated coconut shell fibres with up to 1,200m²/g of surface area, capturing dust, pet dander, mould spores and microplastics on every rotation.

For YEARS I’ve had a ‘clear the crud’ cough for the first hour of every day. I’ve had ZERO coughing in the morning since putting these on our fan. I can’t think of the last product I’ve been this impressed by — I’m a customer for life!

I was surprised how quickly I noticed an improvement in my allergies after installing the Barnakl filters. Literally the morning after, I woke up without a stuffy nose and itchy eyes for the first time in months.

I normally have a lot of sneezing at night and in the morning in our bedroom. We placed them, and night one I had no sneezing. It’s day three and no more tissues needed! So grateful and thankful.

We live in the deep South with too many allergens to count. Barnakl has really improved our quality of life — we’re experiencing fewer sinus and allergy problems! I’m also noticing much less dusting is required, and it’s SO easy to install.

I was debating trying them — now I won’t be without them! Put them on both our fans and what a difference. No more morning sneezing for hubby, and we sleep much better, too! Give them a try — you’ll see an immediate difference.

I’m not one to write reviews unless it’s for something truly amazing — and this is. We’ve been using them for 6 months now with nothing but incredible results. The photos are from our bedroom and our child’s. Every room in our house has one.

These filters have been a total game-changer for me and my fam! We’ve got two cats, my mom has asthma, and my grandma’s with us too, so clean air is a must. I put one in my bedroom, and when I took it off, it looked like it had fought a dust storm and lost! Now we’re all breathing easy.

My oldest’s room always had this funky smell that drove me CRAZY. I put these on the ceiling fan and honestly, I don’t walk into that odor anymore. What a relief! We have them on several other fans too, but this was the most notable change for me.

My dog SHEDS!!! And Barnakl has been absolutely amazing for eliminating dog smell and capturing my furry friend’s dander! I’ve also noticed my sleep improved a lot. I’ve been using them for 3 months now and I’ll never live without it!

I’m really enjoying the pet filters! The first filters I used were wonderful — they just took a little longer to clear the dog odor. I switched to the pet filters and within hours, the pet odor was gone and has not returned. Highly recommend.

MERCEDES G.

I have 5 cats and 2 dogs — to say there’s a bit of pet dander is an understatement. The difference in just a few days is insane.

As an owner of 3 German Shepherds with 2 whole-house air purifiers, I thought, do I really need another? All I can say is: ‘Where has this been my entire life?’ I was shocked at all the gunk the filters caught after 2 months. Money well spent vs two $499 units.

    Easy to install an exciting for clean air!

    We live in Brooklyn where there is a lot of street traffic and I’m excited to have our air filtered in our great room where we have a ceiling fan because it’s both the kitchen and living room combination and so there is a lot of dust, but also cooking that happens in the space. Our ceilings are fairly high at 10 1/2 feet and so while I can have an air filter on the floor in my home, the upper level air is never quite filtering the way I want it too, so this was a great solution. I just installed them today and I’m really excited, especially now that all of the flowers and leaves are out on the trees. It feels like the perfect time to spring clean my air and help with some allergens that must be floating around everywhere.!! installation was really simple I am excited to turn my fan on each time now.!
