Every few uses, unless I wear it for several hours at once. Typically, I only wear a mask for 15-20 minutes while I shop. Sometimes I literally wear it for a minute or two (pumping gas, running into post office, etc). I keep it in the car until I've used it "enough."
The other day, we went to Downtown Disney and were there almost 4 hours. Those got thrown in the hamper when we got home.
I don't worry at ALL about the virus being on the surface of the mask. I just don't believe that is a likely source of transmission, given what is now known about the virus. I am more concerned with bacteria from my own mouth festering on the inside of the mask and causing skin breakouts on my face.
