Question: What is the difference between the 15 gram and 22 gram fiberglass exhaust filters?
Answer: The 15 gram fiberglass exhaust filters (PA/GA Series) offer greater overspray holding capacity at the expense of efficiency. The 22 gram fiberglass exhaust filters offer a higher efficiency rating at the expense of holding capacity. This is the sliding scale that fiberglass filters are bound to, more of one property means less of the other. So what if you need greater efficiency and higher capacity? The drop-in solution is to switch over to a higher end filter such as Paint Pockets.
