They are exactly the same size, which I was expecting; however, there were noticeable differences. I noticed these filters had a thinner, more transparent outer layer. That concerned me so I decided to cut open one of each to assess the quality of both. I confirmed that this company makes a thinner outer layer; it’s very transparent. The second layer was about equal in type and thickness. The carbon layer on this filter feels less permeable and of better quality. I wish the outer layer was thicker, but knowing the inner layers are better quality makes me feel better. As for breathability, they feel about equal. All in all I’m satisfied with this purchase.

Bought for my granddaughter..she likes them..they do have an odor.

Great masks for the money. I never bought before Covid so can’t compare what they use to cost. The mask itself is good quality, I used one on my run this morning and it was so much easier to breathe in than the cloth ones. No issue with loops breaking even though i had to remove and put back on a few times. Love that it has the metal strip to make it shape for your nose. If my area continues to enforce mask wearing I will definitely buy again. Also yes they are made in china but they were made a full month ago so concerns about them being virus compromised.

These are excellent disposable face mask. They come nicely packaged and a certificate of authenticity is included in the box. I have to wear many hours each day. The ear band on a different brand of masks was an issue because it wasn’t always secure. These ones are comfortable and secure. I will purchase again before my box is empty. Nice quick delivery.

Recently my Houston Rockets officially masks came in. I seen that it had an opening for filters, so I ordered these and they fit! 💯👍🏿
