I am not impressed with Hastings. I have cut up a bunch of different brands of filters. The Hastings was nothing special, much like the ST and most of the $3 filters despite costing almost twice as much. Fram was inferior, and the AC had half again more filter area than any of the others. If Baldwins aren't any better than Hastings, they are a waste of money. The more I learn, the more convinced I am that if you can find the OEM reasonable, use it, otherwise hope there is an ST for your application.
