You might think that disposable face masks are only for doctors and nurses who work in hospitals or offices. For a long time this was the only time you saw it, but now you see it everywhere you look, especially during flu season.
Don't think of them as something you will never use because you will probably find that at some point in your life they will be very useful and even necessary. They may seem expensive to some for almost the bulk of the money, but they are worth the price if they do the job they are supposed to do.
There are various types of air filter respirator face mask available online.
If you get to the hospital today during or before the flu season, you'll see a supply of disposable face masks on your way to the door. Most offices and hospitals now want you to wear them if you have the flu, have caught the flu, or are just afraid that someone else you talk to might catch the flu.
This can be very effective at stopping the spread of flu in medical settings where you are most likely to have the flu. Feel free to use it and don't feel stupid unless you like the flu of course.
If you have a newborn during flu season, you may want to have disposable face masks for your home visitors if you are not sure whether or not they are okay. If you have premature babies that you bring home during flu season, you need to be more careful because they may have weaker immune systems. If you don't want guests exposing your premiums to the flu, lock your house. There will be people like your grandparents who you may want to visit. You can offer face masks and let them know they don't agree.
