  2. Filter works great. 5 Star Review

    I use this filter along with their regular carbon filter and RO filter to make my beer. I have no off flavors associated with chlorine or chloramine in the finished product.

  3. Product is made very well. 5 Star Review

    Posted by on 31st Jan 2015

    This is made very well and has very little loose dust.

    It has a high capacity for Chlorine and Chloramine. I run two of these in series. My city water has about 1ppm Chloramine and 0.32ppm Free Chlorine, and these reduce Chloramine to 0.01 according to a Hanna Checker. The checker is accurate to +/- 0.03, so this may actually be 0.00. The Free Chlorine is reduced to 0.00.

    These are very easy to flush. It is important to flush them before using them. You should disconnect or remove any filters downstream, so they don't get fouled up with the dust. The manufacturer recommends that you flush them for 10 minutes before use. You will see the water come out black at first, but it quickly clears up.

    I used to use Catalytic GAC in a refillable cartridge, but this has a higher capacity and is much easier to replace!

  4. The best chloramine filter out there 5 Star Review

    Posted by on 3rd Jun 2014

    I looked all around when I discovered that my city was using chloramines. Buckeye has had the best RO supplies in the past and no surprise, after looking for hours on the internet, I could not find a cartridge that could handle as much or for more gallons than this one. And it costs the same or less than any others you might find.

  5. Great savings 5 Star Review

    This unit is a good deal and performer. Not sure if I really can tell if it's any better but the price is =)
