Quick Overview

Why does BRS recommend this?

The easiest way to know if your city uses chlorine or chloramines is by using the LaMotte Test Strips for Free and Total Chlorine.  Water Treatment facilities can change their treatment process without notice and usually change the amounts of disinfectants used depending on the season.  With simple low cost, quick, and easy to use test strips that give reliable readings, every RODI system that filters city water should not be without them.

Free and Total Chlorine with test strips from LaMotte.  These test strips are used to identify if you your city uses chloramines or chlorine as the main disinfectant. Test strips are also used to determine when it is time to change your carbon blocks.

By having the ability to test for free and total chlorine will allow you to take a quick reading from your tap water.  If the Free Chlorine reading matches the Total Chlorine reading then no chloramines will be present.  However if the Total Chlorine is greater than the Free Chlorine reading your city is using chloramines.

•Range and sensitivity is 0, 0.5, 1, 3, 5, 10 ppm

Full Details

Testing procedure for identifying the disinfectant your city uses. 

1)  Run your tap water for two minutes and collect a water sample.

2)  Dip the test strip as directed on packaging and read results. 


  • Up to 5ppm total chlorine & same free chlorine = Chlorine* 
  • Up to 5ppm total chlorine & zero free chlorine = Chloramines*
  • Zero free and total chlorine = Well water*

*This is the most common interpretation of results. If you have trouble reading or determining results we suggest calling your city hall or water treatment facility to make a final determination.  


Testing procedure for identifying when your carbon blocks need to be replaced. 

1)  Run your RO/DI system for 30 minutes and collect a sample. Sample needs to be water which has passed through the carbon blocks but not the membrane. You can remove the tube coming from the last carbon block to collect the sample or collect a sample from your waste water tube, whichever is easier.

2)  Drip the test strip as directed on the packaging and read results. 


We suggest replacing the carbon blocks if you get any reading above zero. Readings over zero are an indication that the carbon blocks ability to treat for all types of contaminants has been depleted. Absolutely replace carbon blocks once the reading surpasses 0.5ppm

  • Effective By Dave D on 10/16/2015

    The results were easy to read and agreed with my local water company.
  • Fast and easy By kiel on 9/1/2015

    Great cost effective way to cheaply test your carbon block.
  • Did not tell me much. By fishman on 8/30/2015

    Bought this to find out if there were and Chloramines in my RODI water. According to the test there where none, but it also read that their was no Chlorine in my tap water. Which I thought was strange.
  • Does What It Suppose To By Matt on 4/10/2015

    Good method to check if chloramines are in your source water. A little difficult to to read, if color blind like me, but works as expected.
  • Get something else By Jeremy on 4/9/2015

    I bought these strips to test my water for chloramines, to determine when to change my filters. Unfortunately, they don't seem to detect much. They don't detect any free or bound chlorine, either in my tap water or filtered water. Perhaps I just got a bad batch, if others' experiences are different, but what I have is not useful to me.
  • Works well By Tex on 2/25/2015

    Product is relatively cheap and works well!
  • Very useful:) By Hamad on 2/21/2015

    Very useful test kit, you can test for chlorine and you can easily know when to change your carbon also you can test your water if you have fresh water tank
  • Now I know By Bruce on 2/12/2015

    Gives a definite answer to the question "when do I change my carbon filter?"
    Should pay for itself many times over by letting you get all the goodie out of your prefilters without running them too long causing damage to your membrane(s).
  • Works fast By Frag Shark on 12/16/2014

    This is a must have for anyone running an RO that's not sure if they have chloramines. They are easy to use and give a very fast and easy to read reading.
  • good By pops on 11/13/2014

    Everyone with an RO system, reefs, etc., shpould have some of these!
  • Great Stuff By DonB on 11/2/2014

    LaMotte + BRS, great combo. Test strips do their thing.
