Not as advertised/pictured.
Just opened this up - it does not come with the filters shown in the picture. I have Amazon Prime, but this item required a shipping charge.  Which I was aware of - but after reading reviews thought this would be a good choice on mask. Not - single black "filter" and not the 2.5 ones shown in pic. Will be returning, I would contact the seller first but do not see a choice to do that.
