3M P95 Respirator Filter Adapters

thingiverse

I'm creating filter adapters for my 3M P95 Respirator using furnace filter material as the medium. To improve sealing around non-uniform shapes/sizes of cut filter material, I modified the Exhale Filter cover by suatbatu to add a lip around the opening. Next, I modified the intake filter adapters by mikelyden to match the same design and enhance airflow for easier breathing. The gasket and standard adapter remain unchanged but are provided here for reference. For more variations, please see mikelyden's original designs. A flexible material like TPU should be used to print the gasket.\r\n\r\nThis setup still accumulates some condensation inside after several hours of wear. However, it remains far more comfortable and produces less condensation than fully 3D-printed face masks I've tried.
