  • With the expansion of our commercial brewery, we were not achieving the needed water flow rate through our filtration system and contacted H2O Care for a solution.  Steve Theriault did a great job of explaining the technical issues and configuring a system to not only solve our flow problem but improve the filtration and an anticipated lower maintenance interval and cost.

    H2O Care was helpfully flexible in scheduling the installation around our production schedule and the resultant installation is first class and working well.  The came when they said they would and did what they said they would at the cost they quoted.

    We are pleased with the professionalism and quality of every aspect of our dealings with H2O Care and will continue to use them as our primary resource for any water filtration issues.

  • My house’s only water source since 1987 has been from Water well, like most people in New England. Water filtration and Well maintenance is  crucial to supply of  clean, reliable, and safe water. The H2O Care, Inc team of Steve, Cindy, Matt and Bob did such an outstanding first class job from water Analysis, to water filter design, scheduling, professional spectacular installation and operation of system that I have not seen since 1987 any company in this field to provide. It is perhaps most important to also note, that H2O Care Inc. team has brought a total level of new professionalism to this field, that I had not witnessed for 35 + years. Great job Team and please keep pushing the envelope for best service and care for our American houses in the neighborhood. THANKS for treating our home like yours. Stay well and safe.

  • H2O Care was the best option around as far as system quality, price, and most importantly, service. They were knowledgeable, patient, and down-to-earth. We had several issues plaguing our well water and now have the cleanest (lab tested), best-tasting water I’ve ever tried! I’m confident that my family is safer because of this system. It’s obvious that the people at H2O Care truly do care about their customers and aren’t out to just make money.

  • It was time to replace a 30+ year old water filtration system especially with a high radon count in a recent water test. We compared companies and felt Steve Theriault and H20 Care, Inc. were the most knowledgeable and experienced choice. We were pleased with the wealth of information provided especially from our many questions and happy with the crew and new installation overall. I highly recommend H20 Care, Inc. for your next water filtration system!

  • My wife and I had a great experience with the quoting and installation of our water filtration system. David and the crew were very knowledgeable, attentive, and responsive. When my initial test results of our system came back, we were contacted quickly in case we had any questions. Would highly recommend them.

Regular water quality testing is important whether you use a public or private water supply. However, if you have a private well, the responsibility of ensuring your water meets drinking water standards falls on you, not the town.

We strongly suggest that you test your water regularly, at least once a year per the EPA’s recommendations. At H2O Care, our water specialists can help in determining the most sensible approach. We also provide many well water treatment options to keep your water clean!
