Product review (5 stars): You people drinkin the wrong water -Bobby Boucher
I bought these for a 2015 GE Cafe fridge that needed the RPWF-E filter - if you just need an RPWF, skip to the next paragraph. As others have mentioned, the E at the end means the filter needs a genuine GE filter because of an RFID chip that is supposed to protect against leaks, but really forces you to buy the GE filters for $50 each. Placing this in the slot caused an immediate error which stopped water flow, and required pulling the RFID chip from the back of the old filter and placing it on the new one. This is very simple to do, as there will be a raised box on the back of a GE filter underneath some adhesive which can easily be removed and placed on any new filter.

Other filters on Amazon complain that what the buyer received was not a new filter. My order contained a box of 3 filters that were individually sealed in plastic with an additional plastic cap over the nozzle where it connects to the fridge. While the environment may hate us all, it gives some peace of mind about new/used filters in a crappy box.

The box states you need to run 2 gallons of water through the filter to get it set up, but I live on the edge so here's what will happen based on how many ounces you dispense:
0-6 ounces: your fridge still has reserve water in the line, it's coming through fine
6-32 ounces: Water is slowly entering the filter and air is sometimes coming out instead. It's a mix between a California drought and Yellowstone erupting all over my rug
32-128 ounces: every 12-16 ounces there's a bit of a pause and a pulse of more water. It sounds like the stream of that old guy who's staring at you in the urinal while he pees
128+: water pressure is up to par with the genuine filter, water tastes clean, and you feel good because you bought 3 for less than the price of 1

With the -E filters, the fridge will still think it's the same expired one and alert you every month to replace and buy new genuine GE filters. My original filter that came with the fridge tasted TERRIBLE, and I've yet to notice that with these. If you're wiling to put up with an alert every month telling you you're overdue, this is for you. If you want the genuine experience and a 6 month alert telling you to change out the filter, the genuine GE filters are available on amazon for a few bucks cheaper than retail. If you're really cheap, there's a filter by Waterdrop that's a bit less than this one, but I haven't used those so I cannot vouch for their quality (though I have seen them on clearance at walmart for $1 a filter).

Overall I am very satisfied with the ease of installation (despite GE's best efforts), taste of water, promptness of shipping, water pressure, no leaks, and price. I will update this review in the event that these filters do not meet the 5 stars that I have awarded them.
