Yes, it had a lot of good data in it, but it is getting quite dated now. Much has changed. Many of the filters are no longer made by the same company. Champ still makes many of the same filters, but the larger ones are all Ecore now. I have documented the downward trend in media area in several brands. However, it is quite difficult to tell if that is offset by better media.

Nothing has changed with the Frams as they still have the substandard construction and premium price.
