continually touching them isn't a good idea anyway, they are being unwise when they do that imho - unless your hands are scrupulously clean you could just be putting virus particles off your hands & onto the mask... ready to be inhaled, or just deposited onto your face from the mask, or even from your hands as you reposition it.Before I get out of the car I out the mask on and get it right and then just keep it on rather than some people who seem to take em off & put em on as they go in and out of places. I know I'd forget.

Best to do as you do - put it on with clean hands then dont touch it again until you ready to remove it for washing/disposal, & then wash hands after removing

A friend told me this evening that there have been studies done which show that mask-wearing leads to increased (re)inhalation of carbon dioxide and possibly viral particles. Can anyone confirm this - or alternatively deny it?
Abstract said:Successful masks were muslin at 100 threads per inch (TPI) in 3-4 layers (4-layer muslin or a muslin-flannel-muslin sandwich); tea towels (also known as dish towels), studied as one-layer, and two-layer expected to be better; and good-quality cotton T shirts in 2 layers (with a stitched edge to prevent stretching). In flat-cloth experiments, tea towel, cotton 600 TPI in two layers, and cotton 600 TPI with flannel 90 TPI, performed well, but two-layer cotton 80 TPI did not. Multiple layers should be used, at least two, and preferably three or four; however there is a trade-off in that this increases the resistance to breathing.
I've been making my own masks and getter better at it! - 4 layers of fabric and a KN95 filter which I slot into the middle of the mask. I wouldn't wear a homemade mask without the filter.Posting this here, as it does include homemade masks:

@Wits_End One of my neighbours is a tailor and is making masks. I bought a couple off him. He said I could come to him for the KN95 filters. Now that I am making masks I just go down and buy the filters from him.Where do you get KN95 filters from? I've been using coffee filters![]()
