I have never experienced dirty acetylene. I have experienced dirty argon several times and it was a disaster. Is your filter specifically for acetylene? Once a bottle is contaminated, there is very little to be done to clean it. This is compounded by the fact that they usually do not mark a dirty bottle or pull it from service when it is returned.

A few years back there was a shortage of acetylene. Apparently, there are a limited number of manufacturing plants in the country. One of the big ones had an explosion and it was some time before they got back on line. I was told by my supplier that during that period, there was a cleanliness problem.
