10 Best Drinking Water Test Kits 2025 in the United States

The Varify 17 in 1 Complete Drinking Water Test Kit is designed for anyone concerned about the quality of their drinking water, whether it's from a well, tap, or city source. One of the standout features is its ability to test for 17 critical parameters, including lead, chlorine, fluoride, and bacteria. This comprehensive testing capability gives users a broad understanding of their water's safety, which is invaluable for health-conscious individuals and families.

A significant strength of the Varify kit is its ease of use. The color-coded system allows for quick interpretation of results, making it simple for users without technical backgrounds to assess their water quality in a matter of minutes. Additionally, the kit includes a total of 100 test strips preserved in sealed pouches, ensuring freshness and accuracy over time.

Accuracy is another highlight, as the kit aims to deliver reliable results with its premium quality materials and design. The bacteria tests take up to 48 hours for completion, which may not suit those needing instant information on water safety. While the kit covers a wide range of contaminants, some users might still require more specialized testing for specific pollutants, depending on their local water conditions. A portion of the proceeds supports initiatives for clean water in Central Africa, appealing to consumers looking to make a positive impact with their purchases.

The Tap Score Advanced Home Water Test Kit is a thorough option for anyone wanting to check their drinking water quality, whether from a well or city supply. It tests for a broad range of contaminants—116 in total—including heavy metals, bacteria like E. coli, nitrates, and chemical byproducts, which makes it especially useful for homes near farms or industrial areas. The kit uses certified EPA-approved labs, ensuring accurate results you can trust. You’ll get your detailed report within about 5 business days after sending in your sample, which includes clear health guidance and taste assessments. The kit also comes with everything you need to collect and send your water sample, plus expert support via chat if you have questions. One advantage is its easy-to-understand report and professional backing, which can help you decide if you need a water filter or other treatment.

The test kit is a bit more expensive and requires shipping your sample to a lab, so it’s not instant like some in-home test strips. Also, the kit has a 12-month shelf life, so you should use it within that time frame. This product is ideal if you want a comprehensive, reliable water test and don’t mind waiting a few days for lab results. It is less suited for quick spot checks or those wanting immediate home-based testing without mailing samples.

The Tap Score Professional PFAS Test Kit is a reliable choice for anyone wanting to check their drinking water for harmful PFAS chemicals, including PFOS and PFOA among others. It uses the EPA Method 537.1, a trusted testing process able to detect extremely low levels of contaminants (below 2 parts per trillion), making it very sensitive and accurate. The kit includes everything needed for sampling, like sterilized vials and prepaid shipping, which makes it simple to use at home without needing special skills. You collect your water sample, send it to their certified labs, and get results within about 10 business days. These labs are EPA, NELAC, and ISO certified, ensuring high testing standards and trustworthy results.

One notable strength is the support from experienced scientists available if you have questions. However, the test is specific to PFAS chemicals, so if you want to check for other contaminants like bacteria or heavy metals, you would need different kits. Also, the kit itself expires after 12 months, so it’s important to use it within that time. While the wait time is reasonable for lab testing, it’s not instant, so those needing immediate results might find this limiting.

This kit is well suited for homeowners concerned about PFAS contamination who want accurate, lab-certified results with easy sampling and good customer support.
