Seems to fit well with the adjustable ear straps and I can breath well with it on even with the filter in.
These masks are my husband's go-to. Even with the filter they have enough space between the mask, mouth & nose to breathe well & still fit securely on the sides of the face. That's a major plus in the AZ heat. I love these in the feminine styles they have. Would definitely recommend these.
Masks fit well. Easy to clean. Easy breathing even with filter in place. Have ordered 3-4 times.
