An effective & good way to disinfect the N95 (and other types of) masks is at 70°C (~160°F ) for 30 minutes.
Latex (and the other materials) are safe up to this temperature without degradation.
I purchased a cheap toaster oven off Amazon for this exclusive purpose, as my better half wouldn't allow the existing one in the kitchen to be used for this purpose!
Added:
The masks should be 'hanging' off a wooden rod, and not touch metal surfaces in/of the oven.
