I've had a 39 warming (KR 15) filter for a few years, that somehow got "loose" and the glass would rattle.
I looked very closely and could see that with a specialized filter spanner, there was some access, but not having any of these tools, I did the following:
Have the outside of the filter facing to the R like a wheel, use your thumb and middle finger with a clean microfiber cloth and hold the filter tight.
With your right hand, rotate the filter edge cw with your left hand firmly holding the center of the filter glass.
A couple of rotations should hold tighten it up, and your filter should be like new.
