Actually I was looking (well being bombarded by adverts) for masks, and even those from reputable companies with disposable filters in them, all had disclaimers saying that they were not a protection against the virus. So begs the question of why we are having to use them, if they don't offer protection. If they don't protect the wearer, then they also don't protect those around them. I hasten to add I do wear a face covering, a neck tube well ruched up together into several layers, in shops but absolutely hate it. I find them so distracting that I even forgot to take my shopping with me yesterday, I was in such a rush to get out of the shop and get my face uncovered! And don't get me started about the added cost to the environment of all the disposable masks, especially those just discarded on the ground, trees, other people's gardens, wildlife getting caught up in them, etc. Rant over, sorry.
