Human faces come in all different shapes and sizes. Getting the right fit can be tricky, but is very important, as how your mask fits is imperative to the filters’ ability to work effectively. Respirators should be a snug fit, without any gaps for unfiltered air to leak through. 

Here are 2 ways that will help you  make a more accurate purchasing decision.

I’ve got a tape measure and I’m not afraid to use it.

  • Suitable for seasoned mask wearers who have purchased one too many a saggy mask, and doesn’t have time for any more nonsense. You get to ditch the next three points and get yourself a mask that is going to fit.
  • Appropriate for all ages
  • High success rate

First, measure from the middle of your nose to about a little over an inch under your chin, this would be your reference for the first number on our size chart.

For the width can be tricky, as human nose have different in size. So make sure to add few mm to your measurement to avoid mask to be too small for your nose or your cheek.

Second, measure from right cheekbone to the left, for the width of the mask. Make sure the tape sized correctly. You may use mirror or other’s help to be accurate while measuring.

Use my height and body weight to measure.

  • Appropriate for all ages
  • Varying results
  • Since body weight can differ hugely between people of all ages, body types, cultures and genders this is by no means a fail-safe way to choose your mask size.

The problem with this method is that it doesn’t take these following factors into account.

  1. Your weight maybe not be typical, if you have more muscle mass, maybe you weigh heavier than average, but it doesn’t affect your face size. 
  2. Body types (Ectomorphic, Endomorphic, and Mesomorphic) are very difficult to factor in.
  3. Your height and weight may not correlate at all with face size – this can often be seen in very tall people with ectomorphic body types.

Please refer to our sizing and guideline below.

The Cambridge Mask is a fashion-focused pollution mask that comes in a range of patterns and 5 sizes to fit children and adults. Masks are available in  Extra Small, Small, Medium, Large, and Extra Large. Masks have an adjustable nose-clip and toggles on the chin so that you may tighten and loosen the mask to achieve a perfect seal. If you have any questions do not hesitate to reach us here.

Note: Cambridge Mask has an XS size which is designed for toddlers or very small children. The adjustable apparatus is too big for the mask and therefore we do not produce these at the moment. The XS size does not come with a valve for the same reason. This does not usually create any issues as smaller children do not need to exhale as much air as adults.
