This is the Best RO water filter

This provides my family good, safe, drinking water. This is the Best RO Water Filter you can buy for the price. I live in upstate NY. And every once in a while, we get the boil water warning way after the fact. With these filters we are safe. I test the PPM and it continues to measure 21 PPM output for our drinking water. Municiple water will register a measurement at 395 PPM from the faucet. So, I feel very confident and safe with this superior RO water filter.

My filter housing arrived damaged and after sending pictures to customer service, it was replaced free of charge in a timely fashion.

Overall good unit

The system was fairly easy to install. I did have to order a John Guest Angle Stop Valve 3/8 x 3/8 - 3/8 part number ASVPP2LF (bought on Amazon) to replace the Feed Water Adapter that was provided with the system since the fitting didn't fit my existing cold water stop under the sink. Took about 1 hour from start to finish. Just make sure to fully connect the quick connect lines and fittings. Been a few days since I installed my system and so far no leaks.

Excellent So Far

Got this water system installed by a professional plumber. After he installed it he made the remark that, "you'll have the best drinking water on the planet." That made me feel like I did the right thing. There were other water systems I looked at that were in the thousands of dollars... so I definitely feel like I got my money's worth. We've only had it for a week, and so far the water is great! Haven't had to change any filters yet, so we'll see how that process goes, but I'm pretty confident that this is a top notch system!

Great RO system,

Best deal around, we like the total operation of this unit, we installed the 6 stage unit, nice to have minerals in the water again,really neat, well built unit,
Water is super clean, installed in 2 hours, would recommend it to everyone,

Great Solution to our water needs!

Excellent cost effective solution for our lunchroom needs!

Great Product - excellent water quality

The reason I did not give you five stars is because when I ordered a seven stage replacement set, you sent me six items. I know you people are better than that just based on the quality of your product.

Great high quality faucet

I really like this brushed nickel faucet it matches my brushed nickel moen faucet perfect. The quality of the faucet is better than I expected it to be. Easily to install & I would certainly recommend.

Pleasantly Surprised

Unit arrived quickly and in good condition. Very easy to install and works as described. Currently using for drinking water and two ice makers. I was a little worried about the ice makers after what I have read, but everything is working great and making lot's of ice.

Bad filters

I believe these filters are defective, I am corresponding with someone from your company but getting nowhere, please contact me or assure me you are sending new filters. I would have given no stars but it was not an option. Until filters were changed system worked well. 254-733-5351

We are a senior couple and was able to install the unit by ourselves, We love it. Use it everyday. Thank you for your service and the quick delivery.

Great faucet

Ordered the faucet and it arrived a few days later, in good working order, and is installed and looks and works great!

Nu Aqua 7 stage UV with Booster Pump

Awesome unit

The spam is annoying. Filters look a little different than last time, so will see. The ones I replaced worked great.


Bought this filter system a little over a year ago. It leaked badly on install. Nu Aqua was very helpful in sending me a complete new system free of charge. It installed without any problem. I am now ready to replace the filter but can get no response other than the web site continuing to show "out of stock"...have tried to reach out via calls and response.....confused.

Excellent sistem

This system gives us clean, soft and good tasting water. Everyone in our house loves it. Highly recommended


I live in a "pre-war" building in a city that, supposedly, has the best water treatment facilities available. However, after spending the past winter running a cool-air humidifier and then seeing the kind of dreck left behind from the tap water, I knew I did NOT want to continue drinking that stuff.
I now have a countertop NuAqua filter and the change in the taste of the water is remarkable! At my age, and with my health as it is, I'm supposed to be drinking much more water, anyway, and the NuAqua water filter system certainly makes that much easier and more enjoyable to do!

Great Water

I am really enjoying my NU Aqua system. It is very quiet and I love the little light on the handle. While my plumber installed the unit, I drilled the 5/8 inch hole through my quartz countertop. It cost me about $90 for 3 diamond drill heads. The salesman at Home Depot advised me how to drill a hole through quartz and it was actually quite easy. Like others mentioned, the adapter received was not the right size and my plumber had to go get me one. My plumber was very pleased with the unit and he will recommend it to others. The unit fit very comfortably under my sink leaving plenty of room for all the cleaning stuff I keep there. The water tastes great and I use it very conveniently, no need to purchase gallon water jugs anymore. I will definitely recommend Nu Aqua to others.

The best ro

Long story short, had people come in to sell us another RO for 20 times the price. Did all kinds of testing on our Nu Aqua system . They left a little deflated. This system by far is the best and you can’t beat the price. Im a recovering cancer patient and great water is important, not to mention no more plastic bottles, thank you Nu Aqua!

awesome system

multiple people in our family have bought a reverse osmosis from nu aqua we are very happy with the system but I did order the wrong one I meant to get the system with a pump but either way the pumpless one works great if you have city water but do not want the taste this will fix it

Best on the market

My son and I did alot of research when deciding on the best RO system for our homes. It wasn't a quick decision but we are so happy with our water filters. Thank you so much.

7-Stage Filtration - Bargain and Good Results

This system is not compact, so I concluded that if I was going to manage to get filtered water that gets rid of Fluoride as well as other contaminants, I was going to have to locate the filter assembly remotely (not under the sink). To manage this, I was fully expecting to need to find and install a booster pump, but the 7-stage Nu Aqua system actually includes a pump so if this is a consideration for you, relax, it's already part of the package.
I was also pleased that the filter assembly comes pre-assembled so 50% of the construction outlined in the instructions is done. Be sure to install the UV Light and Tube, though. Since most everything else is done, it would be easy to overlook.
I did have one leaky connection on the Nu Aqua assembly that I had to deal with not to mention one of my own where I had not fully inserted the Push-to-Connect completely into the fitting. Their leak was in the Stage 1 Sediment filter which just wasn't fully tightened. Take your time and be sure to follow their directions to only open the valve halfway until you are certain their are no leaks. It will minimize the mess.
Since I located the filter assembly in my basement, I wasn't able to take advantage of Nu Agua's clever color-coded polytube, but it is definitely a nice feature, but an extra 12-24" for each colored tube would have been nice.
I also split the output to run water to my sink and fridge so I ended up buying a few fittings and 25' of polytube plus Nu Aqua's fridge kit. You might want to plan on a trip to the hardware store as part of the install if you are doing anything beyond a basic installation.
Since I had to cut some holes in drywall, the bottom of my kitchen cabinet and the floor to route the polytube which had to be fished through the ceiling of a finished basement, my installation took a lot longer than the 2-3 hours it might have taken if I installed it under the sink, but even with all of that, I was performing the initial flush after about 8 hours.
The results are outstanding. We are fortunate to have decent water in my town, but the TDS was cut in half down to the low 20's and the taste improved from what I already thought was pretty decent.
You can pay more for a filtration system, but I really don't know why you would. Nu Agua's system, at least for the first couple of weeks of operation, is a great value producing excellent quality water.
