Purflux, owned by Sogefi filter division. They are distributing Purflux, Fram, Coopers Fiaam. Basically, they tells that Purflux is OEM quality, Fram is premium, and Coopers Fiaam is standard.
I used many of those filters (air, oil, cabin, fuel) and the build quality seemed serious. Purflux have more media surface because of their "plissé chevron" thing. On euro cars we run Purflux for like 30000km (on cars that are specified for that OCI) and they are still flowing and in shape.
