It's quite worthy to keep a box. You can rewash the masks and reuse them many times.Super comfortable, breathable mask. Just wore one for several hours at the zoo this morning. Bonus that they can be washed and reworn several times.I dislike when it’s not in plastic sealed bag . It’s not sanitary! But the mask it’s self I really love! I’m debating if I’m going to buy it again.It just seems weird to me that a paper mask would be “washable”. If I wanted a washable mask, wouldn’t I just use cloth? That said, these are good comfortable masks. I have a small face and my husband has a very large face and nose. These fit both of us comfortably. They’re probably best suited to normal sized faces. They tend to ride up a little close to my eyes sometimes and his will pop down under his nose on occasion. They fit comfortably behind the ears for both of us. I keep the box in my car just in case we need one unexpectedly since they’re being required less and less these days and we’re both full vaccinated.I hope this info was useful.Review Result:[Buy Today, Get it Someday, or Skip Past Any day]Buy Today, these masks are a pretty good addition to anyone in our current dark times, stuck behind a mask. They are quoted as being washable and reusable. I don’t know. Based on my use the last few weeks, I would say they are pretty good for as one for work-week or so. That being said, I have to walk a ½ mile to the train station. Sometimes, it is -5 to -10 Fahrenheit.

We haven't tested the washable aspect, but otherwise, we are pleased with this selection.They look disposable, yet it's a 3-ply washable reusable mask!The best part I like about it is a zinc ions which fights odor! They also do not hurt when you wear them for long periods. I have used a lot of masks in the past and this is one of my favorites! The price is Right because you can wash them and reuse them!Our whole family has used these masks - the wire nose bridge allows for a good upper seal and prevents the fogging of glasses. The many layers help with filtration. We were skeptical about laundering, and they delivered - going through a typical laundry cycle and being re-used, which is a nice bonus. Our challenge is that some of them had an inner layer that became loose from the rest of the mask, and would fluctuate in-and-out while breathing, which was distracting and odd - we could feel it on our lips, but not an obstruction to breathing, so we took off a star for that - in every other way, they performed as expected.
