They work, but not well
The fit is a bit small.  Either it rides cupping your chin leaving your nose uncovered/unsupported or the other way around; your nose is supported but rides between your chin and lower lip.  I would not recommend these for an 8 hour work day or long periods, but wearing for a short period of time like going in and out of a store shopping or Dr. appointments they work out fine.
