The easiest way to choose your size is to measure the width of your thumbnail and use the following guide:
Small: 1.3 cm
Medium: 1.5 cm
Large: 1.7 cm
X-Large: 1.9 cm
You can place a ruler across the widest part of your thumb to get an approximate measurement. We recommend choosing the size closest to your measurement for the best fit.

Why Choose Us Vs. Traditional Mask
This nasal filter outperforms bulky masks and ineffective sprays by providing discreet, comfortable, and proven allergen reduction.
Hey, I’m the guy behind AirShield™. I’ve spent years working in dusty, dirty environments, and I got tired of choosing between wearing a bulky mask or just dealing with everything in the air.
I started looking for something simple and discreet that I could actually wear while working. When I couldn’t find anything I liked, I decided to make my own.
