Review on ON4HOME Hardness Drinking Water Filter with Fluoride and Aluminum Removal by Jojo Howell

Includes 50 A and 50 B strips, so you can perform 50 full tests for 18 pollutants. I tested the tap water from our kitchen and the water in our Brita jug. The water in our Brita is tastier and doesn't smell like bleach. For some pollutants there were only minimal differences. I wanted to test the chlorine but our water appears to be treated with chloramine and the chlorine readings showed no difference. I read somewhere how to use total chlorine and residual chlorine values to test for chloramine, but they came out the same in both water samples on this test, both 0. I was confused at first trying to read the first strip. The colors didn't match at all. Looking at the instructions for use, he indicates to hold the strip and compare it to the top of the chart on the bottle. On the outside of the box you can see him holding a strip at the bottom of the bottle for comparison. When I held it down, the colors matched. Both drawings can be seen in the photo. In general, tests have shown that our city water is only minimally polluted. I would have to test another brand to compare the results for accuracy.
