Don't take our word for it

“As a physician, I am aware of the potential harms of bottled water so I was glad when our friend Susan recommended Water Doctor.”

We had been using them for many years and NEVER had any more floods, leaks or mineral buildup. I would give them 10 stars if I could!

“Much more efficient than refilling 5g Poland Spring bottles every 2 weeks.”

Those who experience water quality issues (Ridgewood Water) should prioritize this RO system for their family. Use a TDS meter to check the water quality yourself.


“If I could recommend 11/10, I would for this water!”

Have you ever tried water which you know from the first drink, "Wow this water is very good!" You have found the cleanest purest water. If I could recommend 11/10 I would for this water!


“Water Doctor service is amazing!”

Not only do I love the quality of the water filters but everyone is so kind. The prices are also very reasonable. I highly recommend trying them out if you haven’t already!

“I have been a satisfied customer and now I trust them even more with my drinking water.”

When the E.coli bacteria was found in my city water recently, Water Doctor assured me their water filtration system gets rid of the bacteria 100%!!! I have been a satisfied customer and now I trust them even more with my drinking water.


“Good customer service and friendly service, I highly recommend it!”

I am drinking very clean and refreshing water while using Water Doctor.  When my babies were young, I used water from Water Doctor and fed them right away.  Good customer service and friendly service, I highly recommend it!

“The taste is so pure and clean.”

The thing that stands out the most about WaterDoctor water is its great taste! The taste is so pure and clean. Also, when I use it to fill up the humidifier there is no residue or water marks, so it doesn’t need cleaning as often. I love it!!
