Easy to install and provides great water.
[This review was collected as part of a promotion.] The GE REVERSE OSMOSIS FILTRATION SYSTEM GXRQ18NBN was super easy to install with simple push on connectors. System comes with everything you need to self install. Took me about 45-60 minutes to install and has very clear instructions. Youtube video for installation instructions: https://www.youtube.com/embed/qyuab7ou9Io?rel=0. The system and filters provide a REVERSE OSMOSIS filtration that provides the best tasting water I have had. I am on a treated community well and always disliked the water as it was hard water with a strong chlorine taste and smell. The filters removed all the taste and smells from the drinking water. I have ditched the wasteful water bottles for the GE system. The filters last 6 months with normal use and removes 95% impurities. The item description was just as described and I would buy it again.

    Love This
    [This review was collected as part of a promotion.] This filtration system is wonderful! I did not realize how much difference there is with filtered water. Water taste so much better and will definitely be drinking more of it due to this filtration system. I did have a little bit of help from my husband in connecting everything, but it seem to be pretty easy. I think it took him a whole 5 minutes, if even that.

      Not Home Depot's fault but...
      Took the leaking system previously noted back to Home Depot and they exchanged it. Experience was ok. Installed the new one and the RO cartridge leaks where the cap is. Poor manufacturing. This one is also going back and I am going to have to buy online from someone else. GE, you just can't help but manufacture garbage I guess.

        Hi there! We completely understand your concern regarding the bubbles cloudiness and apologize for any inconvenience. The bubbles and cloudiness are caused by air being in the system after installation. This will go away on its own after running for a while. Thank you for stopping by with this review. -Gina@GEA
          Spigot leaks
          This is a complex install and still leaks. The equipment takes up a large portion of your under sink area.

              Worthless
              This is the 3rd time this worthless thing has leaked on me. To qualify myself I’m a licensed HVAC contractor and a longtime municipal wastewater professional, I’m pretty sure I can install push to connect fittings correctly. But they’re cheap and have failed 3 times now. The icing on the cake is it never worked well anyways. The tank pressure was set correctly and the flow rate was somewhere around 2 cups per minute. So for the 3rd time, reaching for a new trash bag that was wet, I knew exactly what it meant. Shutting off my kitchen water, emptying the cabinet, drying with a fan, dinner became ordering in and now it looks like I need to replace the cabinet.

                Filtration System
                [This review was collected as part of a promotion.] Received this unit a few days back and installed , first off installation is a breeze after I installed unit did what instruction said and 24 hours later had system set and ready to use I did have one small leak but that was due to me not cutting line straight recut and no leaks. I love it for my drinking water the only down side to me is my coffee does not have has much flavor when i use this .Over all very nice unit and easy to install and set up Thank you GE.

                  Filter change not very easygoing. Water outgoing too small

                    too small
                    The water tank is half the size of my previous system. Its just not big enough for a family of 3 to use constantly. Installation wasnt too labor intensive. The water line that goes from the filters into the tank hooks to the top of the tank. It leaks! 2 different plumbers tried to fix it, in vain. Its going back!
