Comments about Impact® Face Mask with Elastic Ear Loop:
Very good value. They work good as well. The main drawback is that they are in a box with no plastic wrapping on outside. And when stored in the box takes on the odors/smells of surrounding things, and when you get near the end of the box some box fibers that are in the bottom attach to the mask and could be inhaled during use. If they were contained in plastic or a closed container [...] they would be much better.
