Works but probably 400% overkill and possibly damaging to the masks.

Few seconds is not enough, a minute or two should be. But the problem is any sort of conductive element will cause havoc in the microwave, so you'd want to very careful. Think staples, reflective ink, etc. carbon filters might be an issue as well?

I'm not sure about overkill, a domestic pressure cooker it would probably be hard pressed to reach the required 130'C. Remember the mask would only be exposed to steam, not the boiling water. It would probably be a lot more gentle than dry uneven heat in a microwave.

iMo:
Hopefully you all distinguish between a "face mask" and an "FFP3 respirator".

NiHaoMike:
If it's sunny in your area, just leave the masks in a car parked outside. You'll be surprised how good of a solar collector a car is even on cooler days.
