In that case all I can suggest is searching for an anti-fogging treated 72mm filter or buy some anti-fogging spray such as this from Muc Off to use on the inside of your current filter: https://muc-off.com/products/anti-fog-treatment

That was my thinking - something like what racing drivers use on their helmet visors or car windscreens when racing in the wet.
