This is a useful thread. One request, as you respond, please briefly define the term "EDC" as you imagine it. The term "EDC" for me means what I carry on my person throughout the day. I could compromise here and include what I carry in my brief case. If you're imagining keeping your respirator in your vehicle, then your respirator would have been useless in a 9/11 style attack or similar, and that's the topic of the original post.

If you work in an office building and if you're around your desk a lot, it may be more realistic to store a more effective, more cumbersome mask in your desk. However, I don't consider that option to be EDC.

I don't mean to call anybody out. I'm just looking to make a purchase...
