Anti Pollution Face Cover Air Breathing Valves，for Most Kind of Double Air Breathing Valve Mask
With the Pandemic running full force again. I change these out about every 8 hours of wearing them in my mask. I am High risk, so I wear them pretty much everywhere I go now.

As advertised
These came in a very timely manner, needed to order them as my spouse had already broken the ones that were on our masks. Work great.

Will need a thick gasket or very thick mask material.
Value was ok but a diagram or instructions would be helpful for homemade face masks.

Waste of money
Returned. Membrane was very poor quality and wouldn't reclose. Inconsistent sizing makes them useless and many missing parts.
