    I’ve been using this system recommended by this website for about 1 month now, and I’m very impressed. My girlfriend, who usually drinks coke, and ice tea, is now drinking a litre of water a day! She loves the flavor of the water.

    Another thing is it makes you realize how nasty tasting tap water from other places are. I went to a chinese restaurant and got a glass of water, and it was disgusting.

    So far the unit has been working flawlessly, and there are no issues with it running.

    Just took a bit longer to install in the beginning though.

    I’ve spent the last three decades working in the construction and home improvement business, and I believe that the APEC ROES-50 is one of the very best systems offered at this price point. When a whole house system is out of the budget range of my clients, I always recommend this system. I appreciate that it is made in the USA, and APEC backs its products with consistent customer service and support.

    When you install as many reverse osmosis systems as I do, you quickly see the difference in the quality offered by different companies. APEC’s systems are priced similarly to iSpring’s systems, but in my experience, the product quality and results provided by APEC are superior.

      So, what system do you recommend for a whole house RO system? I already have a whole house filtration system, but not with an RO.
