MASK REVIEW -- WHICH ONE IS BEST??
tl;dr - I highly recommend the Halo Mask (depicted in photos 1 & 2)! It beat out the others by a long shot.
Over the last few months I've been trying out a whole bunch of different masks. I was in jury duty all day every day for a month which gave me a great testing ground for figuring out which mask was most comfortable to all-day use!
I did research to find the masks that focused on breathability and comfort and wound up trying out the following masks. Here's my feelings on them from best to worst
1.) Halo mask - This was the winner! It uses a semi-flexible bridge to keep the mask out of your mouth, which made a little pocket of air in the mask which I think helped make this mask super breathable (even with the n95 filter!!). The inner mask fabric is also reallly soft and comfortable on the face. Their designs are kinda boring compared to some others, but for all-around use the halo mask has become my go-to.
2.) Zensah mask - This one was _actually_ the most comfortable, BUT I think that it's actually a bit too thin to be truly protective (which is part of what makes it so pleasant to wear). The fabric is soft and my favorite part about it was how the straps go around the head rather than behind the ears (allowing you to easily rest it around your neck). If you're looking for a mask for outdoor sports this may be protective enough, but I wouldn't say its effective enough for, say, a plane ride or jury duty.
3.) Fiber-knit mask - this is a cool 3D knit mask that has a single head strap which works surprisingly well. With the filter, it's thick enough to not blow out a candle. On the down side, the material is a bit rough on the skin so it's not comfortable for long periods of time. If you're looking for a low profile exercise mask, then this might be a good fit.
