Has anyone tried Costa filters?

They just arrived. Seems well built. Holes in center tube.

The silicone ADBV seems thinner than any other one I have seen, but other than that seems very nice. Can is pretty thick. To be honest, seems like a PG standard filter, including the media, with a silicone ADBV instead of nitrile. Probably fine for a 7500K OCI. I will use them for 5K.

Looks well constructed, and uses the cream colored robust glue. Nice glue job too, zero sloppy areas.

We never heard back from the manufacturer about the ISO efficiency specs.
