What is a mask frame?

A mask frame is an exoskeleton layer that fits atop of your mask.


Doctors and staff at the UCONN medical center wanted a better fitting and safer surgical mask that could closely match the effectiveness of a fitted N95 mask. 

Under the direction of Dr. Cato Laurencin, graduate students of the CT Convergence Institute for Translation in Regenerative Engineering, developed a “mask frame” that acts as an exoskeleton to be worn outside of a traditional procedure/surgical mask which simultaneously decreases the amount of non-filtered air flow while providing additional comfort. 
Here’s bit more information on their journey.

Additional techniques were developed to allow for custom production for an individual’s specific facial measurements by simply using a photo of a person’s profile and face next to a reference object.

Alongside a team of professionals, production engineers, and commerce specialists, we welcome you to try out our mask frame.

How does Secure Fit help?

Less Gap = More protection and reduction in eye glass fogging!


Our Secure Fit face mask frame is custom-made for each user to ensure a comfortable and secure fit.


The mask frame is to be used on top of conventional masks and provides better protection to the nose and the mouth.


Learn about the difference a gap makes! The frame has been tested extensively and can assure that anyone wearing a mask with the Secure Fit mask frame can still talk, breathe, and even smile. Our attempt is to ensure that the mask has a seal to improve the safety of all healthcare workers. Take a look at some sample photos.

Actual testimonials from customers:

Less Eyeglass Fogging
"I really like how it fits over the masks I make or the ones I can get from work. My favorite thing I love about it, is my glasses don't fog up. A huge drawback to reg. masks when I am at work for up to 10 hrs a day. It is very lightweight and comfortable to wear." -Joan S of Wethersfield, CT
"I forget that I am wearing one. It definitely helps with talking. In meetings and especially conference calls, it's a big improvement over a normal mask." -Anne S of Granby, CT
"I have a small face. When I wear a mask it sort of hangs there. I am like what's the point? With your covering, I finally feel like my mask is doing something" -Laurie G of Torrington, CT
"Thank you! Thank you. Finally my mask doesn't need non-stop adjustment. The mask holder [frame] holds it in place. I set it and forget it." -James R of New Hartford, CT
