So the story behind me having two half-mask respirators is that one day I needed my respirator, which I was pretty certain was a 3M brand (which I bought because I wanted to be sure I could find 3M bayonet cartridges for it), and it was nowhere to be found. I searched everywhere I thought it MIGHT be, and it wasn't there. So I gave up and went to Home Depot and bought the exact same model again. And when I got home, I opened my front door and the missing respirator was sitting in the middle of the living room, on the floor. I would have tripped over it when I left if it had been there then.
So I figured I was getting punked by a ghost and now I had two respirators.
Then I bought a 3M 6900 full face respirator during Covid when I thought the government might come try to gas me out of my house to force me to take the vaxx. I thought it used the same bayonet cartridges as the half mask respirators I have, but now I'm not sure.
I'm going to pull the cartridges off both types of mask and compare them later. I don't want masks that take multiple kinds of cartridges, so I may be giving away these Gersons and buying a 3M half mask respirator for when I don't want to fool with the full face one.
