Other than the hardware, for many 'brands', if one were to break open the filter media casing, it is more likely just another oem which can be found in the market or online.

And most casing are specially molded to fit the brand hardware so one cannot buy alternatives.

Basically water filtration is about removing sediments and odour. As for the rest, I dont think it can be verified other than from the brochure.
