5/ For 3rd point, I agree that N95s are hard to breathe in for long periods
But most people though would only need to wear for shorter periods (eg, grocery store) & there are more comfortable options such as KF94s, elastomerics & others close to NIOSH approval (eg, @one_canopy)
Instead of double-masking, governments in South Korea & other countries got high-filtration masks to their populations
We need a federal effort to do the same in the US
