Water vapor from boiled water seems much easier

  I'm skeptical about that. You can easily put a bunch of masks in an oven at one time. There is no complication at all to that approach and no questions of coverage or distance (did your water vapor get all over the mask properly and at a high enough temp). The oven is fire and forget, pull after 30 minutes. The oven is safer and easier by a wide margin.

    Well I've thought of using something like "stainless steel steamer". Usually if properly distanced, it is heated uniformly. In asian area it's not common to have oven but steamer usually available
