Fantastic for flying
These filters are not like the one that comes with the pro sport mask,but they fit as well. It doesn’t say in English on the package that they are Kn95. Maybe the specifics on the certificate mean the same thing.They arrived promptly and I am happy with them. The mask itself is super comfortable, but this review is about the filters.
Seems like it doesn't fit perfectly in the nose section, so it is a little uncomfortable
I really like the softness and are very comfortable. They are somewhat difficult to get in place in the mask. Also, they are too big for the smaller mask and need to be cut down.
The title says it all. Fits well, tight not too tight, comfy and best mask I've had
