Great inserts that help for multiple things
I got these mainly to find a way to prevent my glasses for fogging up.  I figured the nose part would do a good job at sealing and keeping the air flow projected forward.  The fact that they hold the mask away from the face, to prevent makeup or just keep it from getting damp is frankly a bonus.<br /><br />These really do what they say they do.  They hold the mask off a bit, and seal near the nose.  They prevented my glasses from fogging, and made things a little better as far as breathing. They work well in a mask with a little room to expand, but they do hold shape well and stay in place.  They're silicon, so they should be easy to wash.<br /><br />The only negatives I can find are that they do get a little damp if you wear them long enough.  That's going to happen with any mask type thing though, and at least with these you can pretty easily change them out.
