93xtrista My step-dad rules...it’s a “coughy” filter😂😂 If you’re looking for a DIY face mask to protect others from your cough spray, grab your coffee filter and get to it! https://www.instagram.com/p/B-Pen-OpQGs/?igshid=1n58h8gefa4wp

I’ve just been wearing my tighty whities over my head.

Will that allow for breathing, however? With some of these 3-D printed masks, they’re just one hard material that doesn’t allow for air exchange, so you could be wearing one to the store, and then fall to the floor from carbon dioxide buildup and lack of oxygen. Might as well have a tightened plastic bag on your head.
