If Google Shopping is any indicator of how they're coming along, they've got a ways to go. I recently searched for refrigerator water filters and just went with the top result in Google Shopping. I ended up getting something that isn't NSF-certified, and in fact the company Google recommended to me as the top result has previously gotten in trouble by falsely claiming that their filters were certified.
I ended up throwing them away and ordering directly from Home Depot. At least I can be reasonably sure that they will sell me something I can trust to give me drinking water.
