## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Works well, difficult to get it to sit right.
  

*by L***L on Reviewed in the United States on September 15, 2018*

This mask has been a life saver for me.  My seasonal allergies get so bad in the fall that my throat swells up.  With this on I can sleep fine without issue.  There also was absolutely no rubber smell at all that other reviewers complained about.Getting it to sit on my face right was a chore.  The upper part is supposed to sit on the TOP of your cheekbones, if it doesn’t then there is a gap between the bottom and your chin.  It tends to slide down over time requiring adjustment from time to time.  Having some non-slip strips on the upper cheek portion of the mask that would stick to the face would help solve this problem.Otherwise it works well.  I’ve found I can go about two weeks per filter using it for sleep every night without my allergies kicking back up if anyone was interested in how long the filters last.  I also wish that the mask were just a tad smaller.

### ⭐⭐ 







  
  
    Broken in 8 months
  

*by L***G on Reviewed in the United States on August 25, 2019*

Slight smell when I first got it, not too bad & it went away in a day or two. Gray fabric started to separate from mask within first week. No biggie, I mostly care about function. At that point I'd have given it a 5/5 function, 3/5 quality.Now the ear strap is broken. Function is drastically reduced, and the gray fabric has continued to separate from the mask. Will be buying a different brand, or just go back to disposables. In 8 months I got about 24 uses from this mask. Disposables may be more economical.

### ⭐⭐⭐⭐ 







  
  
    Not great for average US male's head.
  

*by D***A on Reviewed in the United States on November 9, 2018*

I wear a 7 3/8 hat and am 6 ft tall.  When the ear loops are in place, the bridge is at eye level.  Useless.  Still, I will keep it because it works well without the loops under my full face MC helmet.  Anti-fog design works well, if used along with an anti-fog spray.  No bad odor; good airflow.  Face was warm today at 43 degrees.
