Went to Grainger and the 3m seemed to fit pretty well. So I got it over the North. but now I'm confused what you guys do for filters. I'm looking for the setup where I can change out the P100 filters more often than the Organic Vapors. The guy at Grainger said the P100 would clog up quicker. So in other words the filter that has Organic and P100 in one unit would be wasteful.
What are you guys doing that have the 7500??
Thanks!
