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.

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

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

It seems it doesn't work to test tap water

Great job

I don't think its accurate

These test drips are excellent! There are many of them in the container and they read the water quality very accurately. Very affordable. And it gives me great peace of mind to know that my water is good quality. Highly recommend.

They work fine.
