Lite Air Filters
The airinum size guide
To find the correct size, we recommend to combine the two measurements below, the weight measurement and the eye-chin distance measurement.
1 WEIGHT MEASUREMENT
The weight measurement is strongly correlated with the length and size of the face, making it a great measurement for mask sizing.
|L||Over 70||Over 155|
2 EYE - CHIN DISTANCE MEASUREMENT
The eye - chin distance measurement is a very accurate method for estimating the correct mask size.
|L||Over 11.4||Over 4.5|
|M||10.2 - 11.3||4.0 - 4.4|
|S||8.2 - 10.1||3.2 - 3.9|
|XS||Under 8.1||Under 3.1|
If you get diffrent recommendations from the 2 methods, follow the one from the eye - chin distance measurement. If your weight or eye-chin distance is on the borderline, pick the bigger size to ensure a better fit.
