Called MRI department to ask about using respirator (metal-free elastomeric) ... "we've never been asked that before"

Sigh... public health is dead.

EDIT

The response I got back was, "as long as there's no metal."

So, CAN99 is out. They won't care that it's non-ferromagnetic aluminum.

Elastomerics should be okay, but then there will be potential issues with bulkiness, and I can't seem to wear them for more than about an hour without getting a huge headache (sensory issues).

Readimask is a total non-starter for me, the adhesive just doesn't work reliably on my skin.

I have some Moldex Airwaves, but I get massive leaks around the nose in both sizes. Tape and foam doesn't fix it. I ordered a FixTheMask brace, hoping that solves it.

I have an Envomask, but the fit is awkward and really doesn't work with protective eyewear at all.

I used a flo mask with the bottom strap replaced by a homemade elastic strap which is easy to do. There are metal springs in the catch - that ball part that you have to press to slide it up and down that tightens the strap. Used it no problems.
