All-New 18 in1 Drinking Water Test Kit-125 Water Quality Test Strips for Well Tap Test Kit,Water Testing Strips for Home Drinking Water Testing,Hardness,Chlorine, Lead,Iron, Copper,Fluoride

Wasn't able to get the result I was hoping for in regards to testing the filter in the shower, but these seemed to work well and easy enough to use. Just take your sample with the included tube and add a strip. After a few seconds compare it to the chart and it'll tell you what's what. I was disappointed to see that the shower filter was basically the same reading as the sink water, but with a slightly better hardness reading. Kind of doubting the efficiency of the filter.

These testing strips work fantastic! They read accurately, they hold together well and read clear results.

Very handy for RV when traveling, lots of different tests on one tab. It will also test the wholding tanks. Easy to read.

I bought this because I was concerned about the water levels in my house. Did I need this many? Absolutely not I don’t even know if they’re accurate but it says my water is good. Just a little bit of hardness. Haven’t tried it on bad water to see if there’s a difference.

I don't think its accurate

Didn't work. Didn't change color at all on any of the squares, we absolutely have fluoride in our water. Worthless.

Great job

Great for testing drinking water. Water is clearer now. These are not great for testing pool water. Neighbor was using these. I explained how these are used. His pool looks good now. Bought a pool kit.
