Cotton Round Filter Adaper

This is a cartridge that goes on the COVID 19 Mask, specifically with the Filter_N95_connector. It makes it so you can place a cotton round or any filter in and have a tight seal around whatever thickness filter you use. The adapter screws onto the connector on the mask, then you place the Holder (the wagon wheel looking piece) and the screw on the cap. or as I like to do it: assemble all these parts that I added- ie...cap, filter, holder, and adapter; this makes a cartridge. Then, you screw it onto the mask. The cap is desigened to bring air in from the back, so as to limit exposure of droplets. it is a remix and modification of a cap from alphaa.
