Bests & Worsts Reviews from Amazon

I had a new whole house water filtration system installed and wanted to see if there was any difference between my straight well water and the new faucet water that has been filtered, so I bought two of these tests. Let me just say this... I'm now happy with both purchases. The filter and this test kit. Although the results were nearly identical, there was a positive hit with the "potentially harmful bacteria" from the well, but it was a negative result from the new filtered water.
