Saying

★★★★★ Rated 5.0 / 5.0

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
★★★★★ Rated 5.0 / 5.0

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.

THERESA ✓ Verified Buyer
★★★★★ Rated 5.0 / 5.0

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!

PENNY J. ✓ Verified Buyer
★★★★★ Rated 5.0 / 5.0

We live in the deep South with too many allergies to count. Barnakl has really improved our quality of life — we’re experiencing fewer sinus and allergy problems!

ELAINE R. ✓ Verified Buyer
★★★★★ Rated 5.0 / 5.0

I was debating trying them now I won’t be without them. Put them on both our fans and what a difference.

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.

Every 30 days. Subscribe and save 25% on auto-deliveries so you're always ready when it's time to refresh.

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.
