Wow, this is fabulous! They spent almost $5000 to buy and test every mask available on Amazon.

If you click on a mask it will take you to a page with the test details. More incredibly, most of the masks also have 5-7 minute video review!

If you click on the "Breathability" column, then on "Grade" twice, you will end up with a list of masks that Pass with the most breathable masks first.

Way to go, Lloyd. I've never heard of you or your company before, but I am genuinely impressed.
