    Home RO system

    I’m very happy with the system and the support I received over the phone.

    SpectraPure is the BEST

    This is the RO Drinking Water unit. My supply water is basically undrinkable and I had been buying RO water at a water store. Now I no longer need to carry heavy water bottles around. YAY
    My first experience with SpectraPure was a RODI unit for my saltwater water aquariums. I used that unit for something like 8 years with no problem. I can't give a 10 star review, but definitely would if it were an option.
    If you have no experience with installing something like this, I would recommend hiring a plumber, as every application is different and additional parts may be needed.

    Awesome little system

    Love this system! I've had it installed under my kitchen sink for over a year and it does great. Its much easier to work on than other brands I've owned previously. Thanks SpectraPure for the awesome product!

    Excellent unit

    I have owned the original system for over 13y. It’s easy to use and replace cartridges when needed and R/O membrane. This unit never leaked when I installed it correctly...lol. The tank was large enough for all my needs, filling a pot, making a gallon of ice tea, filling my wife’s coffee maker, or a single drink of great tasting water, and even to top off my fish tanks. They probably won’t leave this on the review but, I also tapped off the return line to the facet and ran the line to my fridge ice maker! Never bought another over price manufactured refrigerator filter again!

    Hello, and thank you for the positive review. Have you ever found the need to flush out your storage tank and or rinse it? We do like to recommend that you do this at least once a year to avoid any build up of algae. Also, do you change out your filters every 6 to 8 months? We recommend a new RO membrane every couple of years.
