Finding the Perfect Fit
Not All Masks Are Created Equal. Just like every face is unique, so too are the masks that protect us. A mask that fits snugly on one person might leak or feel uncomfortable on another.
How to Use the Mask Selection Tool in 3 Easy Steps:
- Select Your Head Size
Choose the size that best matches your head shape to ensure a comfortable and secure fit.
- Pick Your Activity
Let us know how you plan to use the mask—whether for work, exercise, or everyday use—to find the most suitable options.
- Get Your Recommendations
Proceed to see a tailored list of masks designed to fit your needs and preferences. It’s that simple!
Measure the circumference of your head at its widest point, just above your ears and eyebrows. If you need a tape measure, options are available for next-day delivery at Amazon.com. Most people have a medium-sized head. (If you are average height and weight, select medium.)
Comfort and Protection Go Hand in Hand
The effectiveness of a mask isn’t just about the material or design—it’s about the fit. A poorly fitting mask can allow leaks, reducing its ability to protect you and those around you.
Age, Shape, and Comfort
Your face changes over time. What fit well in the past might not fit so perfectly now. That’s why finding the right mask is a personal journey.

Masks Have Different Purposes
Respirators ensure strong protection against inhalation hazards like chemicals, dust, and infectious particles.
Masks, on the other hand, may offer some inhalation protaection but are primarily designed to protect others from the spread of disease.


Proper Fit Is Critical
- Gaps around the nose, cheeks, or chin let unfiltered air pass through.
- Surgical masks often have large gaps on the side.
- Adjusting the straps and nosepiece can help improve the fit.
- Respirators are designed to fit better and are fit-tested to ensure performance.
