Will you kill me if I point out no apostrophe in heroes?
I’ll add to that by saying masks, unless you are using very specific ones, and trained in their fitting / wearing and re-certified annually ** are not really worth a damn.
** My best mate, until retirement 3 months ago, was my local hospital FITS trainer / certifier, and if you have a beard or moustache then forget them fitting properly. Further, they aren’t generally recommended for use by the general public.
Sorry not sorry: but climbing down off of my horse now.
Na More important things to think about than that stay safe mate and wear a mask that is suitable and obviously correctly fitting by an expert, for me it’s my Harley skull and cross bones bandanna and some £1.99 aftershave from B n M which wards anything off
