Nikken PiMag Waterfall Review and Ranking – The Best Water to Drink?

Nikken PiMag Waterfall Review and Rating

In our Nikken Pimag Waterfall review, we found it just may be the best water to drink. What we found out surprised us.

The Nikken Pimag Waterfall is unique because it does not focus on just one particular attribute of the best water to drink. The Nikken Pimag Waterfall is designed to produce healthy water the body wants and can use right away. Nikken uses the term, Science Replicates Nature. So it would seem the Nikken Pimag Waterfall is designed to replicate a more natural water like our ancestors drank.

Nikken PiMag Waterfall Review – The Filter

Nikken uses some proprietary technology and media to produce a healthy drinking water. The advanced filtration technology meets or exceeds filtered water NSF standards 42, 53 and 372, No Lead.  The filtration is natural without adding chemicals. We will discuss the filtration more a little later.

The system uses a ring magnet of 1,200 gausses to reduce sediment clumping and build up as it helps to condition the water without adding salt.

 What is the best water to drink?

First, for more information and useful Water facts, check out the two articles below.

First, we discuss the 5 top choices of drinking water and take a detailed look at each:

Then, since there is no real discussion of what makes a drinking water healthy, we talk about what we think is a healthy water to drink:
Defining the Best Purified Healthy Drinking Water

The Pi in Nikken PiMag Waterfall

Pi water, meaning ‘life’ water was discovered in the 1970s. The observation of the effect of water led scientist to one particular Japanise valley where the water stream had a remarkable effect on the plants and trees in the area.

Nikken Pimag Waterfall

Nikken scientists set out to create a water filter to duplicate the conditions they found in that valley. Nikken wanted to provide water filtration to reduce and eliminate contaminants the same way nature does without adding chlorine or other chemicals. They added mineral properties they found in the valley to the filter. Then they added a magnetic field assist in reducing mineral buildup. This helps to condition the water. Finally, the water sits in and flows around mineral stones to add minerals to help the body health.  The resulting water was quickly called ‘Pi Water’ or Water of Life.

It should be noted we can not find any test certification on the Pi Material in the Nikken PiMag Waterfall filtration. However, read on to see what we found for the water filter.

The PiMag Water Filtration System

Their water filter is a gravity-fed system of multiple filters which filters out a broad range of tap water contaminants. The filter employs a natural carbon which captures microscopic particles. The charcoal carbon works by absorption. With the high amount of surface area, charcoal carbon makes it an extremely efficient filter.

The water then flows over spheres of Pi ceramic material with the final stage a bed of mineral stones “based on the agitation/fumble filtration provided in naturally-clean streams”. source

The ceramic in these filters also help to filter out pharmaceuticals which are showing up in water sources.

Fiction or Science?

We know this sounds like fiction you would find in a fairy tales, but the Nikken PiMag Waterfall has a lot of science to back up, but read on.

The advanced filtration technology meets or exceeds filtered water NSF standards 42, 53 and 372, Low Lead. All three Standards

Standard 42
42 is called the Aesthetic Standard mostly con concerned with smell and taste of the water. It does not deal with the health properties of water. Standard 42 is what you find in Refrigerators and most Pitcher type filtering systems.

Standard 53 
53 is called the Health standard. It is designed to filter out heavy metals including arsenic, cadmium, copper, selenium and many others. Standard 53 also will filter out inorganics such as fluoride, nitrate, and nitrite. It also targets VOC’s or Volatile Organic Compounds formed when Chlorine combines with water.

Standard 273
273 is low lead compliance, so important to human health and especially children.


Mineral Water

Using just a basic pool or spa chlorine/acidity tester you can buy at most hardware or pool/spa supply stores, we found a consistent value around 8.5 pH. We tested all kinds of water from bottled water to tap water from different cities as the source water, and the results were very consistent. That pH value is a very healthy value.

Nikken does not have a system of gathering testimonials like Amazon, so it is hard to quantify like other products we review. However, we did talk with owners of the Nikken PiMag Waterfall and found very enthusiastic and a happy group of owners. Our sense of the results would be in the (4.8 / 5) stars equivalent range of Amazon’s rating system.
To our surprise, we heard some common themes of both pets and children preferring the PiMag Waterfall water to almost anything. Many parents told us how their children would ask for water more so than soda.

Some complaints were addressing the need for a water unit on the counter. One person told us to keep the unit out of the sunlight to avoid algae problems. [See the Disclaimer part of this review about a trace element of Silver to counteract bio-growth in the system.]

We did look on the internet and read some negative reviews, but those were all old reviews over six years old and given for a different water purifier model, not the PiMag Waterfall.

The Recyclable polymer is certified to be non-toxic, BPA, Phthalates, and Bisphenol free.

Reviewer’s Thoughts

Nikken PiMag Waterfall review thoughts and summary.

The Good

Nikken PiMag Waterfall Review – Finally, a water filter system with straightforward on what it filters. In our opinion, it builds a lot of trusts and speaks about the company.

Another nice thing we see in this system is the intention to give this water the structure of natural water. They wanted your body to recognize this as a natural water. The Pi material, the mineral stones, and the magnetic field all represent the natural state of water flowing downstream.

This natural water effect could account for the stories of pets and children naturally preferring the PiMag water. Plants love the minerals in the water.

We asked Nikken if they ever planned to produce an under-counter model and the answer was quick and assured, “No.” Why? Water is a solvent and if it sits in a tube of any kind the quality of the water is affected. They can only give the certification if the water comes out of the spout and into the glass.

We also liked the lack of wastewater, and the gravity fed nature of the system which does not need electric power to operate. The Nikken PiMag Waterfall is very sustainable.

Our own simple tests verified a pH around 8.5 which is excellent give this water all the health benefits of a Mineral pH water to the body. We tested different types and brands of water with results very close to all the other results.

The Bad

Keep it out of the Sun. Even with the Silver to mitigate bacteria in the filter, keep it out of the sun. The silver is not good for fish, so keep your fish out of it. Both negatives did not deter the loyalty for the product shown by the people who use the Nikken PiMag Waterfall. We saw the same enthusiasm and loyalty from only one other system we reviewed.

We did notice the warning to use with potable water and the very direct statement of what his system does. The Nikken PiMag Waterfall is designed to be used with Municipal Tap Water, which has an array of disinfectants in the water.

The Ugly

ahhhh ….. we got nothing

The Summary

 Our Nikken PiMag Waterfall Review showed us it is one of the best, if not the best system we have reviewed to date.  This is especially true if you live in a water district where the water is potable. Many may not have heard of the product, but here it is anyway. This product will move on to our head to head review with another system.

  1. We use to be Nikken Distributors and own the under the counter PiMag system which I found out today we can no longer purchase replacement filters for. If this is the only option for PiMag water, what is the fix for drinking cold PiMag water?

    • Nikken has moved away from any water system which stores water [in a tub] or any place after the water leaves the water filter. The quality of water can only be certified as water coming out of the system. Water stored in any pipe/tube will pick up properties of the tube and lose its quality.

      The Nikken Waterfall it the current model of Nikken water filtering.

      Cold Nikken water? We pour it out of the Waterfall into a glass container and store in the refrigerator. I have heard of people putting the entire Waterfall into the refrigerator. We also store Nikken water as ice and drink ice water that way.

      Hope that helps!

  2. I really like this Nikken Pimag waterfall. I just need to know if the container is BPA free. Thanks, Brenda

    • Yes, it is. In fact, it goes beyond that.
      “PiMag products are made with recyclable and biodegradable materials, including a polymer that does not leach chemicals into the water as some plastics will.”
      In other words, the biodegradable material will break down into the soil.

      Hope that helps!

  3. What is difference between the Burkry and the Nikken water purifier?

  4. What is difference between the Burkry and the Nikken water purifier? No first time on here.

    • That is an excellent question.
      Just speaking in headlines:

      Nikken PiMag Waterfall
      inexpensive filters, flow meter so you know when to change the filter, Filtration Standard 42, 53, low lead certification, my tests show consistent pH 8.4v-8.5, excellent on filtering chloramine, Rabid fan base, Nikken would have helped to protect Flint Michigan water issues, does not waste water, no electricity needed

      Recommended for municipal water supplier only. City tap water kills biologics, Nikken filters out the disinfectant chemicals, Voc’s, and more.
      Not recommended for Well Water [although I use for well water]
      Initial Cost is higher than Berkey

      Lots of filters combinations [ note, well water folk do not need Floride filters], Class 1 filter [which is why they market it as a survival system], Class 1 takes out most biologics, Filter Cost is reasonable, Higher rated time between filter changes, Rabid fans base, less expensive than Nikken, would have helped in Flint Michigan water issues, does not waste water, no electricity needed if your water is known [reputation] to be bad source water, start with the Berkey

      While I trust the filter claims, they are not certified, no flow meter – so how do you really know when to change filters, the assembly is a tad harder, filter type will need to be known, pH values? Have not been able to test and Class 1 filter would imply pH below 7

      My decision: At home, I’m on well water, but my area has a reputation of good source water. We are very close to a clean [by today’s standards] river. We do not have gut issues. In the city office, we also use the Nikken.

      To avoid using electricity and staying away from a water wasting, if source water quality gets worse, my plan B is to get a Berkey and prefilter for the Nikken. Yup, using both for drinking water.

      I hope that helps.
