Every since we had a few virus scares like H1N1, Sars etc. I have been planning on buying some good quality masks in case we ever need them. So I had a few questions. Has anyone used the NanoMask like in the link below? It seems like I remember reading that they did a good job because the seal around the face better. At the time this stuff was sold out every where so I want to buy before another scare happens and you can't get them for several months. Nano Mask Is this the company that makes them? They show up on web search but I don't see the product on the site. NMI Health Are there better options for small portable virus protection?What are your plans in case of a wide spread virus outbreak or something similar and you can't stay cooped up in your house? Do gas masks filter viruses or is it common to be able to buy filters that are multi purpose and filter gasses and viruses?
