Customer Reviews and Concerns 

Waterdrop N1

“I purchased b/c tap water was growing red algea and stunk. i put a house waterdrop particulate filter and then my tap runs from 280-300 TDS in the house and when RO.. it shows 15-35 TDS which i confirmed. absolutely love the machine and product. i take extra precautions to supplement trace minerals from celtic sea salt” 
-Amazon Review
“After the first tank of about 40 TDS reading, I have been consistently getting 99+ TDS reading. I have been having to flush every week to get it back to 50-60 TDS Level only for it to go back up. I average about 1 tank per day and always dump out the entire tank when refilling but no help. I also fill the tank from my tap, which is hooked up to a 10 stage filter. This is not a good product”
-Amazon Review


“It’s a sleek machine, barely makes a noise. I live in central FL, and city water here has a sulfur smell and taste. It also is hard water. We moved and our regular filter did not fit the new place’s faucet. That old one (it was a countertop Aquasana one) did a good job improving the quality of the water, but the hardness was still there. However, with this new filter, the water has a bottled water quality to it: no hardness and no sulfur smell or taste. I have had this filter for a couple of days now and am very happy with my purchase.” 
-Amazon Review
“I have had an AquaTru for a year, and it has been a huge waste of time and money. My first problem is that the unit would lock up after I washed the front container. Customer Service sent me a new base unit, but that didn’t fix the problem. I found that the unit would eventually restart on its own if I waited overnight, so I would make an extra pitcher of water before I washed the components (which you are supposed to do weekly), and keep my fingers crossed that it would be back in operation the next morning.”
-Amazon Review
