Was traveling and felt more comfortable wearing the N 95. I am glad I was able to purchase. They fit my face. Wearing it during the cold months. So I did not feel like it got too hot, which is a complaint I hear.

Seem to be good quality. Arrived quickly.

They work great

As describe. Needed for work. I checked for myself before buying on the cdc.gov website for Niosh approved n95 and company name, model, Approval number it was on there. *check yourself

These mask are as close as I am going to get to the 3M mask that are so cherished in the medical community right now. I had some 3M respirator mask before CoVid (for woodworking,etc) I really can not tell you the difference between the two as far as quality. It has a decent seal around my face. The elastic is a looser than the others, but you can tie a knot to tighten. I am very happy because the price was reasonable and the quantity will help make the dollar stretch. 11/27 update*** without tying a knot in elastic it is tight enough. I feel very safe in these. I wear them for an 8 hour work shift. When I take off mask you can see how well it seals around the face by the imprint it leaves around your face. Initially your face is hot under the mask due to your breath, but after a while you adjust to this. It is expected from these type of mask. Definitely a 5 star product

This mask is good and affordable.

Great product

I can't believe the price. I thought I'd go ahead and buy the box of 20 and then give away the 17 I'll never use. But everyone I know seems happy with the el cheapo particulate filters which are ineffective against viruses. I think I'll keep wearing them after the hysteria diminishes because I haven't gotten sick once since I began wearing N-95 masks, not even the seasonal pollen sniffles when I work outside.

Not sure why people are staying that these are knock offs of N95. I checked the CDC's website and they are listed on the approved N95 list. I don't have any complaints with the fitting, it fits like it should if worn correctly.

For the sake of science, I sacrificed one of these --- I dissected it. I found four layers. The one brand of fully-American registered N95's that I tried before had six layers. I don't know if the difference makes any difference (so to speak.) Other than that: the straps are glued onto the mask rather than stapled. I have a large head; so the glue came loose on the first try. I'm stapling the straps to the mask now.
