I have a Pure Power SS reusable filter, and love it. If you read the literature, the PP filter passes all of the oil THROUGH the SS mesh in the filter, instead of just across a paper element, as virtually all normal paper filters do. If you think about it, passing all of the oil through a SS mesh seems like a much better way to filter oil than passing it across a pleated paper element. The SS mesh also has almost no resistance to the flow of oil, in contrast to a paper filter element. The PP filter also has two magnets in it to grab ferrous particles from the oil, and I have to believe that these magnets right there in the oil flow would be able to hold onto ferrous particles much better than any magnets placed outside of a regular filter. And, the outer cover of the PP filter also has heat dispersion fins machined into it, to cool the oil as it goes through the filter.

Cleaning the PP filter is not difficult nor time-consuming. You just take the SS mesh element and swish it around in parts cleaner or soapy water, then blow it out and let it dry. Takes all of 10 minutes total, and most of that time is soaking and drying.

Yes, the PP filter is expensive, but it's much much better than a paper filter at filtering all of the oil that goes through it. It puts almost no drag on the engine, because the engine doesn't have to work to force oil through the filter... it flows through the filter nearly effortlessly. You can blow right through the SS mesh.

A few years ago, one of the biker mags did an independent dyno test, and after they put the PP filter and new oil in, their test bagger showed a 9 HP and 7-8 ft/lb torque increase over the previous dyno run using a paper filter. I didn't buy the PP filter for any potential HP/torque gains though - I bought it because I want my engine oil filtered using the best technology available, and I think the PP filter is that.

Paper filters are ancient 1940's technology that is still used on modern, high-performance, and demanding air-cooled H-D engines. That just doesn't make much sense to me. PurePower makes filters for all kinds of heavy-duty vehicles - including aircraft, that have far more demanding performance standards than land-based vehicles do - and they know what they are doing.

I do not see the "PURE POWER" system paying for itself.

As far as "reading the literature", anyone knows that stats can be manipulated to show anything.. If you think that the "PURE POWER" filter system is so great do you have one of each of your vehilces? I'll bet you don't, B]
