If you have low immunity or just want to protect yourself, these are great. I wear them on airplane flights to protect me from germs passengers may bring on board with them.
These masks should not be crunched to maintain their effectiveness. I found a plastic lidded bowl that these fit in perfectly. So, when I pack them, they maintain their shape. And, they stay clean.
