## Customer Reviews

### ⭐⭐ Keep shopping for another mask.
        
*by C***Y on January 4, 2019*

Fit is horrible.  The seal around the cheeks and chin suck. I'm not happy.
  

### ⭐⭐⭐ Doesn't seal around my jaw/chin but it might for you
        
*by N***L on November 20, 2018*

Edited: Excellent customer service. I was contacted by the seller who refunded my money. One size never fits all, but one size fits most, so I think this mask is worth ordering and trying on considering the price point and ability to return if the fit is not right.Original review: I bought this mask because of the bad air quality in San Francisco due to current wildfires in Northern CA. I had already been using a Cambridge N-99 mask that sealed well, but I thought this might be more comfortable as it wraps around the head, instead of looping behind ears. Unfortunately, this mask only seals well around the nose and upper cheeks, but leaves HUGE gaps under the chin and around the jaw line. And when I mean huge, I mean I can fit 2 fingers between the mask and my chin, and 1 finger between the mask and my jawline. There is no fixing this no matter how tight one ties the band. One size does not fit all AT ALL! If a mask does not seal well, it is ABSOLUTELY useless. I had purchased 2 (one pink and one blue) and one of them was still in its original shipping package and the one I tried on still had its filters in their sealed packages. I wanted to return these items less than 24h after I received it, but they are apparently "not eligible for return" for reasons unclear to me. Don't waste your money. There are way better masks out there.
  

### ⭐⭐⭐⭐⭐ Stylish, sized well for a teenager, effective
        
*by K***X on September 3, 2018*

There's been a lot of smoke and dust in the Pacific Northwest lately and I wanted to get a dust mask for my daughter. This fits her very well and is cute exactly as pictured. She wore it out camping and it works very well for the campfire smoke, she didn't come home with a sore throat from the smoke which is uncommon. The mask is neoprene and so it smells like neoprene when you get it. We just soak the mask overnight in some vinegar let it air-dry and that killed most of the smell, then my daughter put a drop of peppermint on one of the filters which covered up any remaining plastic smell. by the time she came home from camp and everything smells like wood smoke so that issue is very short-lived. no problems with durability wearing it through the weekend, the mask stayed on her face in place no problem
