Amanda Abbott created a spreadsheet with a lot of data on 60+ different elastomerics. There is no standardization as each manufacturer has their own sizing charts. So if you are looking for a new mask or looking to upgrade your PPE, there's now information on measurements.
There are even information on whether or you can create 3D-printed covers for the filters and paint the mask(s) to remain stylish during the creeping apocalypse.
If you live in or near Portland, Oregon, you can also contact Amanda for test-fits since she has most of the model. The only way to know if something is COVID-safe is to try the masks on, but they are non-returnable.
