3.1.1.1 Choosing your Mask size
How to measure your face to establish the most likely HM1400 size for you. This process can be
undertaken in two ways.
NB: The most comfortable size for you, or the size which enables you to achieve a fit, may be different
from your recommended mask size depending on your facial features and preferences. Also, if in
between sizes (e.g., if you find your measurement to be between small and medium), both sizes
should fit but one size may be more comfortable than the other.

Written instructions:
Option 1 – Self measurement and sizing chart
1.
Measure the distance from the bridge of your nose to the tip of your chin using any convenient
measuring tool. Do not follow the contour of your nose.
2.
You can either download and print your mask sizing chart from
www.corpro.systems/resources, email [email protected] and ask for a downloadable
version, or request the chart directly from any Corpro Representative.
3.
Use the sizing chart and map your measurements to find your most likely size.
Option 2 – Sizing calliper
The sizing calliper recommends your mask size without the need for explicit measurements. The
calliper can be purchased as an individual item.
1.
Place the tip of the more curved, shorter side of the calliper on the tip of the chin and move
the other tip of the calliper gently towards the bridge of your nose until there is contact.
