HMPL Face Mask
Who are these for? These are for anyone who doesn't want to contribute to the spread of the virus. These ARE NOT medical grade masks, they WILL NOT keep you from contracting COVID19. Only N95 masks can do this, and those masks are in short supply and will be used by professionals working directly with COVID19 cases.
That said, these are a great option for everyday folks, essential workers still tasked with getting out there and doing what they do, people who work with or are around high risk individuals, people who may be asymptomatic or don't have access to testing. There is so much uncertainty right now, obviously the BEST action you can take is to isolate, stay home, please! Not everyone has that choice right now, and these are at least a small line of protection to stop you from potentially infecting other people. Some defence is better than no defence.
These are not to be worn at all times. They are to use when you have to go out in public. It's recommended that you wash your mask frequently, ideally after 4 hours of continuous usage. (These are totally machine washable!)
