How to choose a mask size

To ensure the mask is the right size, please check when you inhale there are no gaps between the mask and the face which could allow air to enter. The mask is probably too small if it is pulling your ears forward or rising above your chin. We base the size on body weight. 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. The second number is from the middle of your left cheek to the middle of your right cheek for the width of the mask.

Infant Mask - Extra Small

We do not  offer masks for babies under 1.5 years both due to the choking risks and as babies lungs aren't able to overcome the resistance to draw air properly through our filter materials. A healthy child from this age onwards should be able to overcome the resistance to airflow due to the mask and therefore would not have their oxygen intake limited. Depending on the reason for the use of the mask from this age up it may be beneficial to use a mask rather than expose such as a young child to high levels of pollution. Any respirator should only be worn by children under close adult supervision and should only be worn when required.

As the extra small size is indeed very small, and really designed for toddlers or very small children. The adjustable apparatuses; toggles and nose clip are too big for the mask and therefore we do not produce these at the moment. You may also notice 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.
