I had a box of masks that I gave my hubs to use. When those are gone it is going to be the ones I make at home.
Perfect?.....no. Better than nothing at least.
I am using 3 layers of my best quilting cotton and building in a pocket for disposable filters.....if I can figure out hat filter material is best then that pocket is there.
Fit matters A LOT. I have found some patterns absolutely horrible for fit.
I am using this pattern and find it fits well for hubs while I had to decrease the size for myself.
