$89.95 too much to pay for an oil filter?

Oh, like an "edge filter" then. An edge filter is where a stack or coil of filter media draws fluid through the space between the media faces this way rather than through the media itself.
That allows the manufacturer or user to control filtration efficiency by controlling the pressure between the layers.

Advantage: Filtration can be made super efficient with super fine particles even with a cheap and relatively porous media. (Like adjusting the pressure to catch bacteria size particles with plain old cellulose media paper)
Because as the tension is increased, the media fibers between layers entangle with each other and compress to very fine porosity.

Disadvantage: It takes a large amount of media and usually a large filter to get good flow.
 
I currently have one on my Toyota Highlander. The small toilet-paper-like roll is actually a bypass element. The majority of the flow goes through a fine mesh filter. The mesh traps larger particles, and smaller stuff gets filtered out over time through the TP element. It's very well made.

I have used it for over half of the 126,000 miles I have on this car and I can say that it hasn't caused any damage. I was doing 10,000 OCIs for a while, and I was actually using cut-up rolls of toilet paper as filter elements. It was a pain cutting up and sizing a roll of TP to fit, but it was a lot cheaper than the replacement elements. I went back to using their replacement elements with this last filter change.

There was a UOA posted several years ago with this filter and I recall that the UOA was good but not stellar.

When you replace the element, you also clean out the wire mesh filter. Not much gets picked up by this mesh - only a few dozen large particles. IMO it probably is a fairly decent filter but it's not even close to being as good as the Amsoil bypass filter I have on my other car.
