ResMed F30 Mask HumidX Adapter

This adapter gives the clearance needed to use a ResMed F20 HumidX cartridge (with a minor trim) in an F30 Full Face Hybrid mask. 

Printed in PetG for durability, it clicks into place where the cartridge would go. It should fit well enough that it won't come off unless you push the clip arms with a rigid object.

The top lip of white plastic (Just above the ResMed logo) is easily cut with your flush cutters. It is the only cut that needs to be made. It will fly away, so watch your eye!

This is shown in a Small F30 mask, so I assume it will fit in larger sizes. It does put the cartridge closer to you by a small bit, so your lip may brush against it depending on your particular fit.
