What Customers Are Saying
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!
MEGAN W.
Verified Buyer
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.
THERESA
Verified Buyer
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.
PENNY J.
Verified Buyer
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.
ELAINE R.
Verified Buyer
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.
MARY S.
Verified Buyer
I love that I now have a powerful air purifier in every room, just by using my ceiling fans. The odor and allergen control with a fresh filter is noticeable every time. My kids have been sick less, and I don’t take antihistamines anymore. A+ product.

These have helped my daughter with her allergies and asthma!
TAMARA E.
Verified Buyer
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.
EMANUELLE M.
Verified Buyer
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.
ERIN
Verified Buyer
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!
KEVIN F.
Verified Buyer
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.
Verified Buyer
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.
KIM K.
Verified Buyer
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.
DENISE M.
Verified Buyer
I have two long-hair cats and a dog, and these ceiling-fan filters have cut down on the floating cat hair in every room with a fan. Love this product!

Frequently Asked Questions
Nope! The filters are completely odorless and actually eliminate odors in your home
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.
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.

Nope! Each filter only weighs 6 grams and doesn't imbalance the rotation. We also tested the airflow performance and nothing was affected.
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.
