DH puts his on before he leaves the house.
Keeps it on all day at work, 12 hours including bus travel times.
Changes it to a fresh one evey time he takes it off, lunch, drink, if it gets moist.
Takes it off after he gets home and throws it in bucket by the coat rack ready for washing.
He has loads that I made for him. Says they are very comfy. Maybe that's because they are made from soft good quality clothing fabrics, not scratchy blue stuff, sweaty polyester swimming costume fabric or scratchy and sweaty stiff cotton/cheap polycotton bed sheet mateial.
If you're going to keep taking it on and off, you may as well not bother as far a disease transmission is concerned. Touching it with potentially contaminated hands, shoving it in dirty pockets and bags before putting it back on. You are only supposed to touch them by the ear loops to put on and take off. An awful lot of people appear to have no clue, either that or they are only wearing one to avoid getting fined.
Could we not just all stop being so belligerent about masks and try it as an experiment in protecting each other, see if it makes a positive difference to the infection numbers after a few weeks.
I dispare, I really do. This isn't about personal opinion, it should be about a caring community spirit.
Family friend took his 18 year old son for testing last week. Waited in the car and when the son came out, he announced "well, if I didn't have it before, I probably have it now".
Not one person in the test centre was wearing a mask/face covering of any sort. Not the staff, including the medical staff taking the swabs. Not a single person waiting to have a swab taken. Nobody! It was packed with people waiting to be tested, all sat next to each other.
