How We Tested
Our reviewers spent two hours trying a top-rated water testing kit. They collected samples of drinking water in their own homes, mailed them to the kit’s corresponding laboratory, and checked their results. We asked our testers to consider the most important features when using this water testing kit, from its ease of use to the thoroughness of its results. We've outlined the key points here so that you, too, know what to look for when shopping.
What to Look for in a Water Testing Kit
Water source First, you’ll want to figure out what type of water you’re testing — is it from a well or public water supply, or is from your pool or faucet at home? Water tests are often formulated specifically for various water sources, testing for the most common contaminants found in that type of water.
Testing procedure You’ll also want to consider the testing procedure when purchasing a water testing kit. If time isn’t a concern, consider a kit that you send out to a testing facility, as those options are often more comprehensive. However, if you want the results quickly, an at-home kit will give you answers immediately.
Contaminants Some water testing kits can detect a wide variety of common contaminants, such as lead, chlorine, copper, iron, and more. Others just test for one or two contaminants and are usually less expensive. If you know what substance you’re testing for, you may want to go with the latter option, but if you want to know generally what’s in your water, a broader kit is probably the way to go.

What We Like
Easy to use
What We Don't Like
Shipping cost of sending water back not covered
“If someone thought they had a water issue, I think this would be a solid product,” reported one of our testers. Our reviewers loved that it was very easy to use and that the results were comprehensive: “The results really go into detail about all the stuff in your drinking water,” one said, “including the number of essential elements and heavy metals, inorganic compounds, and volatile inorganic compounds.” One thing that disappointed our testers, though, was that users have to pay to ship their samples to the laboratory. “They provide a return label, but it's just a sticker,” said one reviewer. “You actually have to go to the post office to pay for shipping. I didn't like that I had to ship the water back on my own dime.”
