Can You Trust Water Tests By Filtration Companies?
Independent lab testing will never try to sell you a filtration product.
So you got a free water test from a filtration company but you’re just as confused as before. You might even be looking at a quote for an expensive treatment system you’re not sure you really need.
Here’s the thing: Free water tests from water filtration professionals are designed to sell you a system, but not always designed to give you a clear picture of your water quality.

Frequently Asked Questions:
“Do I really need to test my water?”
If you’re interested in filtering your water, then yes, a water test is a smart move. If your water is truly clean, an independent test confirms it. If something is present, you’ll know exactly what it is, how much, and whether or not it actually matters.
“Are free tests by filtration companies independent?”
No, free tests from water treatment firms are often designed to sell a system, not give you the full picture of your water’s quality. They may only look for a few convenient contaminants and frame results to create urgency. For example, a water softener company may focus only on hardness or iron, the issues their equipment is designed to fix, while ignoring the broader range of contaminants that actually determine what treatment (if any) is appropriate for your home.
“Can a lab test really save you thousands of dollars?”
Yes. Spending a few hundred dollars once on professional lab testing can help you avoid years of unnecessary equipment, maintenance, and costly treatment systems you may not actually need.
“Is Tap Score scientifically legitimate?”
Yes. Tap Score is built on the same laboratory standards used by regulators, researchers, and environmental professionals.

How can we support you?
Where to begin? What should you test for? What does it all mean for your health and safety? Answers to all your questions are always a chat or FAQ away.
What test do I need?
When in doubt, we recommend that everyone start with one of our CORE KITS, which test multiple contaminants within a single test and are designed specifically for your drinking water source.

Most people receive results within 3-5 business days after the lab receives their sample. However, some tests may require additional analytical time so be sure to check each kit’s product page for the most accurate estimate.

Your report will rank your water against local and federal safety benchmarks, provide a thorough breakdown of any contaminants detected and how they may be affecting your health or plumbing, and provide non-biased treatment recommendations.
