I purchased a couple of sets of these 3M, P100, 2097 filters to use on my 7502 3M half mask that was also on the same order. I am impressed with their performance. First of all they do an excellent job of filtering out the dirt and fumes associated with welding and cutting steel, and they keep working for quite a long period (three weeks for me welding, cutting, and grinding steel for a good portion of each day, and honestly, they were still working great, they just looked cruddy). Secondly, they are reasonably priced, and lastly I suppose, is the fact that they are super easy to install.
ProsWork great, cost little (comparatively speaking), and easy to replace.
