Product review (1 stars): RPWFE can GTFO...
The new RPWFE filters are garbage. The old filters worked great, but were still pricey. The new filters are designed to "filter more contaminants" than the previous filter, yet a simple ppm detector showed that to be false when comparing the two. My GE Cafe fridge has a hot water dispenser which won't even work now due to low water pressure resulting from the installation of the new filters. Customer support says that the filters are intended to filter 500mL in 30 seconds. Good luck with that. I've tried three of the new filters now and each is much slower than advertised. Do yourself a favor and try to find as many of the old filters as possible to use before you have to resort to using this new filter.
