Most importantly, these masks are very comfortable (they have two bands, one above the other, to wrap around your head, instead of wrapping around your ears) and seal well around your nose and mouth. They are "duck" masks which take a little while to get used to, but of all the masks I've tried, these are the most comfortable to wear.

These masks are very comfortable to wear once you get them on. The seem to give the wearer more breathing room so you don't feel smothered. Finding the straps is easy once you know they are in the inside of the mask. I do not have any fogging of my glasses with these masks.

This is the first time I have ever worn a comfortable N95 mask. These straps around the back don’t dig in and don’t pull my hair. The mask does not fog and is comfortable on my face, forming a better seal. I feel safer wearing this than the KN95 mask or the “ hard” N95.

The most comfortable N95 I've worn. They're not attractive, but they are at least roomy and not sucked in if you breath. Not too hot. Better than others. I watched a video that rated them high in terms of adjusting for a good seal. I used them on flights. Disposal.

My second order for these masks. Good quality and believe they do the job intended. Made in USA. Only downside is they give the appearance of a duck!! But that aside, good purchase at a good price.

Mask fits well and works well (based on the extent to which the filter material collapses during inhalation). The materials and construction are “light-duty” so expect to use only once.

The seal was very tight. I have a breathing issue so need more air with a mask. That being said very good mask

They are comfortable easy to breathe, especially if you need to wear oxygen. It takes a bit to get use to the head straps.. but would buy again

The masks seem well made and comfortable, but the box the masks come in are not plastic wrapped, and the masks are not bagged as a whole or individually. Instead they are all exposed to the air. Any other mask I get are packaged with some kind of plastic protective seal.

These are the most breathable masks I have encountered this entire time of masking! The flexible nose bridge is perfection, far superior to any metal ones I have used. That said, for me, they are not without issue. As a man with a large head and wide face, as I have discovered since searching for masks these last 2+ years, and a trim beard, I'd so appreciate a larger size with 2 improvements. First, longer straps as these are snug, not uncomfortably so but definitely stretched to their max. Secondly, adding an inch or two on either side making it wider would give a better fit and feeling of more security. Because it is pulled on the sides to fit me, the duckbill actually points downward and sits flatter instead of sticking out. It still provides breathability but I know that is not how it should fit. I will be wearing a cloth mask over it just like I have with the KN95s I've used so that is not such a concern. However, because the fit is off, I find myself adjusting these much more than other masks. I wish more mask manufacturers would recognize that it is not one-size fits all and make a few different sizes. Lastly, there is a method to putting them on and there are simple instructions in the pamphlet included in the box right on top when you open it so people complaining about no straps, etc. are clearly not bothering to open that pamphlet and read.
