Here are some adapters that will fit on the North brand respirators. These are to help DIY'ers with getting creative to make filters and filter systems to attach to the mask.
There is 5 in total:
1. North Mask to 3M Filter (will require 1/8 foam gasket)
2. North Mask to 10mm Spigot
3. North Mask to 15mm Spigot
4. North Mask to Cap
5. North Mask to Pop Bottle (will require sealant on the bottle threads)
The one I actually needed, we ran out of North style filters at work but had plenty of the 3M style. So now I can use both brands on my North mask.
I recommend printing with abs and giving it a vapor bath to ensure it is an air tight seal.
If anyone requires any adjustments to these models or would like my original .blend file for them, just let me know.
It's time to start getting creative. Good luck and lets get through this COVID BS together.
