High Flow Montanna filter plug

This is the first time i've bothered uploading to thingiverse, so.. be gentle with me.

This is a version of the Montana mask's filter plug. It replaces the square part that holds the filter in place. I didn't like the airflow of the original, as it made my asthma feel like it was going to act up, this one has much higher air flow.

the mask is usable with any filter material generally, but is specifically designed for P2.5 filters....
