If you have to wear a mask at work...
I have to wear a mask for 8 hours a day at a desk... answering phones.  I have to talk all day long.  It was hard to breathe, my lips were getting chapped from constantly rubbing against the mask and I was getting claustrophobic.  Then I found this !!  Makes a world of difference!  It was purchased as a 10 pack... and within 15 mins my coworkers were all begging for one!  So many I had to reorder!<br /><br />For us... this is a lifesaver.<br /><br />There was one review that mentioned about covering the chin, I wear mine below my nose covering just my mouth and it still provides enough breathing room and space.
