Tl;DR: 70C /158F heating in a kitchen-type of oven for 30min, or hot water vapor from boiling water for 10 min, are effective decontamination methods.

- dguaraglia 7y agoIs there a way to configure an autoclave to work at such low temperatures?
- milksteak42 7y agoYes, most have a low-temperature cycle and the rest can often be configured to include the option.

I'd think an autoclave/pressure cooker/rice steamer would have a much lower risk of melting plastic fibers in masks since they're physically limited to lower temperatures than a typical oven.
- notRobot 7y agoAccording to the document, using an autoclave failed. > Authors found decontamination using an autoclave, 160C dry heat, 70% isopropyl alcohol, and soap and water (20-min soak) caused significant degradation to filtration efficiency.
- elihu 7y agoI think some saunas can get to that temperature.
- fendy3002 7y agoWater vapor from boiled water seems much easier
- adventured 7y agoI'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.
- fendy3002 7y agoWell 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
