Do You know that… It’s not really a alkaline water system…

Low pH Increase: However, the remineralization filter doesn’t turned it to an alkaline water. The remineralization filter just add about 0.5-0.8 to the overall pH which comes up to be 6.5-7.2. This range is consider mild acidic to neutral.

UV Light Sterilizer: iSpring RCC7AK-UV is having the same features as RCC7AK, with an additional ultraviolet sterilizer that kills all virus, bacteria and microorganism. It is best use for well water filtration system which has more living organism.

Do you know that … The TDS is worst than RCC7… NO big deal!

5% Lower Rejection Ratio but : The iSpring RCC7AK & RCC7AK-UV is advertised to achieve 90%+ Total Dissolved Solid (TDS) rejection ratio, a drop of 5% as compared to RCC7.

This is due to the remineralization process that adds in beneficial minerals which increases the TDS.

TDS shouldn’t be the sole factor of choosing a reverse osmosis water filter.

+ The product itself was fairly easy to install.
+ This seem like a good quality filter. Easy assembly, and the water taste great.
+ My particle of 012 are now at 022. Which is still good. Our area tap water is 145ppm.
+ My unfiltered tap water is around 400 ppm! The filtered water is around 43 ppm.
+ You get 95% of everything you need to install aside from a couple tools and possible one additional part
The alkaline levels are still horrible. The pH balance is almost nonexistent. .
I have tested the drinking water with two diffrent sets of tests (drops and test strips) and both came out as ph nuetral.
You pour one glass of water and you waste five down the drain.
The water is great, but don’t expect it to come out fast. I had to wait 4 minutes to fill a water glass.


Verdict : Recommended!

  1. I’ve never really given too much thought about the filtration process of my drinking water, but this article has certainly opened my eyes. The only issue I see for this particular unit is the length of time to get a glass of filtered water, are there other alternatives?

  2. Great post Jay,
    This is such an informative review and I like that you’ve included a video on how to install it. We’ve been looking into getting a water filter so this site has great info on that. 4 minutes to fill a glass of water is a concern.
    Is there a water filter that you can recommend that is quicker to fill up as well as not having to replace the filter as often?

    • The Home Master TMHP is one of the best under sink water filter system that I’ve encounter. It can produce up to 75GPD of filtered water and a waste water reduction of 1:1.
      The suggested replacement is approximately once a year.
      It is an excellent product. You got my words 🙂
