Have fresh air, every day
airdays
Korean KF94 face masks, engineered for the way you actually breathe — light, roomy, and made to be worn all day.
We started AirDays Mask with a simple goal: bring the masks Korea actually trusts to people everywhere else — without the markups, the guesswork, or the customs surprises that usually come with buying from overseas.
The mask we chose is AirDays, made in Korea by COOS Co., Ltd. In its first month on the Korean market it sold 22 million masks and became one of the country's most recognized mask brands — chosen by airlines, schools, companies, and families nationwide. We bring that exact mask, sourced directly in Korea, straight to your door anywhere in the world.
The mask we chose
Made by people who build homes for a living.
We didn't want to sell just any mask, so we went with one made by COOS Co., Ltd, an affiliate of Daewoo — the group behind the iaan and Exordium residential brands. The same discipline that goes into constructing a building goes into every AirDays mask: careful materials, precise engineering, and a refusal to cut corners.
AirDays masks are produced at COOS Co., Ltd's facility in the Ochang Science Industrial Complex in Cheongju, Korea — a large-scale plant running advanced production lines, so quality and supply stay consistent. That's the mask we source, and it's the only one we ship.

The design
The "bird-beak" shape, with room to breathe.
Our signature C-type (cockpit) structure creates roughly 3.5 cm of space between the mask and your lips — so the fabric never sticks to your mouth, even after hours of wear or conversation.
◇
4-Layer KF94 Structure
Outer cover, two filtering layers, and a soft inner lining built for high filtration with a light feel.
≈
Easy Breathing
Low breathing resistance keeps airflow comfortable through long, all-day wear.
○
Secure, Soft Fit
An ergonomic 3D shape and high-elasticity ear bands hug the face gently, without pressure.
◠
Fog-Free Nose Clip
A stable nose clip helps reduce glasses fogging and keeps the mask in place.
Independently lab-tested
The numbers behind the comfort.
Verified through accredited Korean testing institutes (KATRI & FITI) and our own quality lab. KF94 means the filter captures at least 94% of fine particles (around 0.4 µm).
