Of all the masks I've tried, these fit my face the best and compete the least with my glasses. They're comfortable and I like the way they look. In short, I'm such a big fan of these and will continue repurchasing them for the foreseeable future!

I purchased these mask for myself since my child wears the small and they are awesome. I figured these would fit since they are a size large but they are not much bigger than the small. I don’t by any means have a small face but I also don’t have a large one. I found them to be a little to short. No matter how much I adjusted it was either too short it barely cover my chin or it was too low on the bridge of my nose. I understand with covid they do not accept returns so now I’m stuck with 69 masks that barely fit. I have included pictures of the small and large together.
Thank you for your review.
Although the Blue KF94 2D Large masks are labeled as large they are recommended for women with smaller faces and teens. If you are looking for a larger 2D masks we suggest the Botn KF94 2D Large masks which is more in line with the average adult.

Love these masks - the nose wires are great for my glasses and they fit my face very, very well. They're easy to breathe in, durable, and look good. Be Healthy shipped the masks quickly and sent some fun freebies too. I'll be ordering more of these masks from here!
This is my second time buying masks from this website. They are well fitting and very comfortable. They are thin on the edges and thicker in the mouth area, making them quite light. I'm very happy with my purchase, again!
