Review on JFMAMJ Cover Active Carbon Filter by Kevin Harmon

I was very happy with the original filter, not so much with the replacement. They kept falling apart and I felt like I was breathing in parts of the filter. Very uncomfortable! Stopped wearing it because of the filters. I may have to order different third party filters. The extras you get with this mask are rubbish. It fits very well even though I have a big head. That was one of the most important things I looked for when buying a mask. Most are too small for me.
