Love These!
So far, these masks are the best I've purchased.  They're large enough  to cover the chin area, have nose wire, ear toggles to adjust the elastic and filter pockets which are an overlap style so the filters are easily inserted.  And they include 5 filters with  each mask.  I've abandoned the 'double mask' routine and just wear these and feel protected.  Nurses rule; they know what's up.
