What type of fask mask is suitable for people living in zones of yellow or orange air quality?
Airnow.gov rates air all over the USA and lately due to the California wildfire particulates spreading around MORE than California many of us are thinking about wearing masks.
Any recommendations from your people in the ‘know’. I really want to know which N-95 or N 99 mask is best. There are many with different numbers ex.3m 8516 or 8567… I know a hospital mask is not adequate.
Desperate for good information and just a link where I have to cipher because… not great at detailed complicated and highly nuanced writing.
