Respirator HEPA Filter Cassette and cap
thingiverse
These are replacement HEPA filter cassettes that can be made for 3M 6000 series respirators when OEM equipment is not available.I produced a video about assembly and testing of this cassette here: https://www.youtube.com/watch?v=cyhrL93nQNU&feature=youtu.be The components are: 1. Top and bottom of filter cassette. 2. Cap to cut off one filter inlet and use only one filter cassette at a time. 3. Internal cap that can be used to wedge a piece of surgical mask in the inlets so that there is a low risk of inhaling microplastics. 4. Things that need to be purchased elsewhere: Roomba i7 Filter cassettes and silicone sealant.
