I installed the RFB ULTIMATE about a month ago. Before installing the ice had a chlorine taste to it, ruining any drinks we added ice to. Since installing the filter the ice is sparkling clear and completely tasteless. It is important to note that results are not instantaneous. I had to fill and empty the ice tray 3-4 times to rid the system of residual chlorine.

Hi , i bought this filter last year and i am plenty satisfied. I live at Brazil, and we are concern about an chemical larvicide called PYRIPROXYFEN. It's supposed to disturb the life cycle of the mosquito , but could be a relation with the microcephaly. Have you ever test it? If so, is this filter effective? Thanks.

QuickConnect fittings to attach to the refrigerator line do not exist, filter does not match standard fittings. Installation is a nightmare and seems impossible without cutting a new thread. Want to return it back, so it will be just waste of time.

Comment Reply: Standard 1/4" quick connects are provided with the system. Looks like Ross didn't purchase this from us. Manufacturer has been trying to help Ross because of a very specific situation to match with his existing connectors which is very uncommon. Undeserved 1 star here.
