This is a Honda 15400-PLM-A01 filter, made by Filtech Toyo Roki. This particular filter served for a ~7,500 mile OCI (to 15% on the MM) on a 09 CR-V with the K24 engine. Oil used was Honda 5W-20 Synblend (made by Conoco Philips).
The first thing I noticed when trying to cut apart this filter was how thick the casing was. It's significantly thicker than the A02 filter (which is made by Honeywell/Fram). I often use channel-locks to loosen filters for removal, and the A02 filters often get dented simply from the force of the pliers. I've never had that happen with an A01 filter yet. I used a pair of tin snips to open the filter and it took quite a bit of work.
The other big difference between the A01 and A02 is that the A01 has roughly 40% more filter area. If you look at the pleats, you can see how densely packed together they are. Someone on another forum measured the surface area of the pleats and it came out to be 151 square inches!
For reference, the Honda A02 filter has 106 square inches of filter media, the PureOne PL14610 has 108 square inches of media, and the Mobil 1 M1-110 has just 72 square inches of filter media!
Overall, this filter looks like it's in great shape and could have served for another OCI easily (perhaps this is why Honda came up with their recommendation of changing the filter at every other OCI?). No tears in the filter media, end-caps are still solidly attached, the silicone ADBV is still very soft/pliable, and the bypass spring opens as expected.
I did have to drill a pilot hole in order to use the tin snips, so there may be a few metal shavings that got onto the filter media in the pics.
Here are the pics:
