I was going to try to construct makeshift hepa filter masks, but in this video, this doctor says not a good idea.

Filters are constructed of glass micro fibers. Not good to inhale, especially if they’ve been cut. Many layers needed in order to function properly etc...

You could make a homemade mask to uses the PM2.5 filters.

There are refills available on Amazon.
