Review on Enhance Comfort with 5Pcs Face Mask Bracket: Ultimate Support for a Pleasant Wearing Experience by Anferny Pineda

Excellent product! This mask insert makes breathing more comfortable. The soft silicone material is flexible enough that I can slide the insert around my mask's filter pocket to keep it in place along with the PM2.5 carbon filter. The small clips at each end of the liner work well with concertina-style "paper" masks, but offer no advantage with typical 3-ply cloth masks with a filter pocket. I have recommended them to friends who have also been very happy with the product. Delivery time was fast.
