The Britannia - Non-Valve Mask

Cambridge Masks are fashion-forward, reusable, personal protective masks that come in a range of patterns and 5 sizes to fit children and adults. Our innovative and eco-friendly masks are available in Extra Small, Small, Medium, Large, and Extra Large. Each Cambridge Mask has an adjustable nose-clip to ensure maximum comfort as well as adjustable toggles so that you may tighten and loosen the mask to achieve a perfect seal for maximum protection. 

Human faces come in all different shapes and sizes which can make getting the right fit a challenge! However, taking careful measurements is an essential step when selecting your mask as the correct fit is imperative for perfect filtration.

The mask should be a snug fit, without leaving any gaps for unfiltered air to leak through. Please see below for two different ways measurement to ensure accurate purchasing decisions.

Our Recommended Means of Measurement

The well trusted measuring tape!

This means of measurement is for all ages and we strongly recommend this for an accurate way of ensuring your purchase will fit.

Step One

Using a tape measure, measure from the mid-point of your nose to just over an inch under your chin - this would be your reference for the first number on our size chart.

Step Two

Measure from the outer edge of your left cheekbone to the outer edge of your right to cheekbone (about an inch below your temples) to find the correct width for your mask. Make sure to add a couple of millimeters to your measurement to avoid the mask being too small.

Alternative Means of Measurement

Since bodyweight is not necessarily an indicator of facial size or structure, we strongly recommend using the body weight indicator as a back up only if you are unable to measure your self or family members.

Bodyweight and face-size can differ hugely between people of all ages, body types, cultures, and genders, and therefore this is by no means a fail-safe way to choose your mask size.
