Test accurately for know if your water is safe to use.

Introducing rapid and accurate water contamination testing using our smartphone kit. Test your home, hot tub, pool, RV, cottage or other location in minutes.



  • Breakthrough nanotechnology for microbial detection
  • 1000s of times faster vs. lab by reducing testing time to minutes
  • Up to 50 times more bacteria detected vs. lab based culture tests
  • Costs reduced by >50% per sample vs. lab testing
  • Provides quantified results for bacteria contamination versus simple presence tests


Keeping your well, hot tub, pool, RV or home clear of infectious microbial water contaminants is an on-going job. 

We’ve created an end to end solution that allows you to keep your family safe, save money, and greatly simplify on-going microbial water testing for range of disease causing bacteria.

According to the EPA, 60% of hot tubs have microbial contaminants above acceptable limits. Don’t just over chlorinate you hot tub. Exact blue can directly test for bacteria and chlorine levels and advise on how to treat your hot tub.

Are you sure your pool is not going to make you or your children sick? Exact blue can directly test for bacteria and chlorine levels and recommend corrective action.

Private wells are not covered by EPA regulations. Well water is susceptible to Seepage through landfaills, failed spectic tanks, underground storage tank infection, fertilizers and peticides, run off and more.

Make sure the plumbing on your RV is safe and check surface or ground water at camp sites easily

Compromised plumbing can become a nutrient rich environment for bacteria. Check all the outlets in your house to know if any one might be a cause for concern.

Do you have a weakened immune systems due to disease, medical treatments or genetic conditions? Check your water sources quickly to make sure you’re not exposed to microbial contamination unwittingly.


Water contamination is an issue that concerns everyone. 

  • 10 people in Flint died of Legionnaires disease (bacteria illness) (Michigan Live, Jan 2016)
  • Legionella in plumbing systems is responsible for majority of drinking water disease outbreaks (57.6%) (CDC)
  • Over 15 million U.S. households obtain drinking water from private wells that are subject to various environmental contaminants including seepage through landfills, failed septic tanks, underground storage tank infection, fertilizers and pesticides (EPA)
  • Majority of water borne disease outbreaks (51.5%) are related to untreated ground water (EPA, CDC)
  • About 60% of public hot tubs are contaminated with bacteria beyond acceptable limits (CDC)
  • Millions of immunosuppressed consumers can get sick easily and with greater severity when exposed to bacteria not harmful to others

It simply makes sense to test your water for microbial contamination regularly. ExactBlue makes it simple to detect bacteria in minutes. It’s up to 50X more sensitive than traditional lab-based methods and gives you results using your smartphone in minutes.

Can you tell the difference?

It’s not always easy to tell if your water is compromised or not. Can you tell before it’s too late?
