NOPE!
I really wanted to love these.  I've had my vaccines, and thought I might stop double masking and wear my fabric mask with one of these filters instead.  Just one problem--I can't breathe!  For some reason, I get very short of breath wearing the mask with this filter.  Tried it while grocery shopping and I couldn't wait to get out of the store and peel off the mask!  Forget wearing it to work for hours and hours!  Guess I'll keep double masking...
