I cannot attest to long term repeated use but I used this mask/respirator for a one time project of painting my inline 4 cyl Suzuki 1100 engine in a small enclosed not real ventilated space- and I was fine. I put it back into the large resealable bag it came in when I was done. That was 7 years ago and its been in its bag since then. It currently looks fine but obviously Id replace all the filters if I were to use it again.
