  1. Have you heard of Kangen water? If so, how does this compare to that? I see this removes a lot of the stuff that those Kangen machines remove, but Kangen is very much pricier. What do you suggest?

    • Kangen is mainly focus on using electolysis to generate the alkaline water. That is a Japan technology. In my opinion, I would suggest to go for the cleanier RO water system with some additional of Alkaline re-mineralization. That’s sufficient and is less than half of the price compared to Kangen.


  2. Great information above. It seems you really approve of this filtration system. You mentioned it was easy to install. For someone with little knowledge on installing this system or any system for that matter, would you recommend me getting some expert to install this for me?

    • The installation manual is designed for little or no installation experience on doing the job. You probably will save a couple hundred dollars if you do it on your own. My advice is try it out on your own first.


  3. Awesome content! Sounds very effective and affordable at the same time!
    I’m curious to know what some of the health benefits are to having this type of filter compared to others?

    • The most easiest way is to measure the Total Dissolved Solid (TDS) in the water. This system is able to reduce the TDS significantly above 90% leaving your water as less contaminated.
      The other way is based on the minerals that will be filtered. If you refer to the post above, there is a table of contamination that APEC guaranteed to remove by ROES-50 filter. Those are the usual of contamination that we often see in our water source.

  4. I was looking into water filtration systems so it is perfect that I found this post. This will definitely help me decide. Plus I learned a lot about it! Thanks for sharing.

  5. This is a great product, ideal for my father’s farm where the water comes from a borehole. The only problem is the pressure requirement.
    I had a look at the pressure booster and it actually works out great that it doesn’t need electricity as the farm runs on solar power.
    All and all a product I would definitely advise my father take a look at.
