Who can see your viewing activity?
Hi Prof Kahler, thanks for your very interesting talk. I wonder did you look at any other mask designs for example reusable fabric masks? They are much more widely used here in the UK than the n95 masks by the public and I have found they have much tighter fit than the simple surgical mask. ( I wear glasses and don't fog up with them but do with simple masks)
Some fabric masks are better than surgical masks. No question about that. However, if you wonna have full protection of youself they are not good enough and you should swich to an N95 masks. We have studied this quite strongly. You may have a look at the Videos on my Youtube channel LRT7 https://www.youtube.com/channel/UCY-i8Gh3EQ6jG4Lht5_w-DQ and our Paper in the Journal of Aerosol Science. https://www.sciencedirect.com/science/article/pii/S0021850220301063
