Coronavirus Homemade Mask

If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV, (Coronavirus) infection.
Wear a mask if you are coughing or sneezing.
Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.
If you wear a mask, then you must know how to use it and dispose of it properly.
Do you hate every dust mask on the market? Me too. Most of them are more trouble than they're worth. The cheap throwaways never fit your face well enough, and if you just need one for a trip up to the attic or something it might not make sense to go buy an expensive respirator.
Unless you're really into steamed up glasses and breathing in the dust coming in around the damn thing anyway, try making one of your own and protect yourself from coronavirus. If it's going to be for a one time use, you can throw it away or recycle it when you're done. Or you can keep it, as it's also useful in some other ways. I use mine to wrap up my chisel when I carry it in my toolbag. It's handy for a rag, too.
You can just tie a bandanna around your face, but it only ties in one place and can slip off. Cutting a tee shirt in the way I'm going to show allows you to tie it in two places. It's very comfortable.
