Is Penta Water Alkaline? pH Test (Video) and Pro Review

Last updated Apr 8, 2020

Good evening fellow water enthusiasts, I’m your host, Pete. In today’s article, I answer the question: Is Penta water alkaline? I’ll also share a pH test video and my complete Penta water review.

It’s been a crazy month here at AWMS, and I’ve completed a ton of bottled water reviews. At this point, I know everything there is to know about bottled water brands and what to look for in each company.

Is Penta legit? The company claims that its water is alkaline, but I had trouble believing it after I read how they filter their water.

With all the new bottled water brands popping up lately, it’s important for you to choose the best one, especially considering the price of some brands.

Let’s start with the most important part, the Penta water pH test.

Is Penta water alkaline? pH Test (Video)

The young scientist who conducts the pH test in the video below does a great job. I’ve been following his videos, and I can assure you that his tests are accurate.

Let’s see the results below:

Of all the bottled water pH tests I’ve seen, Penta has the lowest pH by far. This is especially troubling since the company advertises a “naturally occurring” pH between 7 and 8.

Later in my review, I’ll tell you why I was skeptical when I read Penta’s pH claim.

Let’s discuss TDS first. The one promise Penta did deliver on was the low TDS of their water. A TDS of just 1ppm is super low. What does this mean? It means there’s almost nothing at all in this water.

Is that a good thing? Most water experts recommend a higher TDS since we do want to get some minerals and electrolytes from our drinking water.

Conclusion: Is Penta water alkaline? No. Does Penta water have a TDS of 1ppm as advertised? Yes.

Next, let’s check out where to buy Penta water in bulk for the best price.

Where to Buy Penta Water in Bulk for the Cheapest Price

Since you may not be concerned about pH and care more about the purity of your water, I’ll show you where to buy Penta water for the best price.

Before I do, I will say that this water is indeed “ultra-purified” as advertised. However, later in the review, I’ll show you how to make an unlimited supply of your own Penta water.

Where to buy Penta water? The best place to buy it in bulk – if you can’t find it locally for a good price – is online through Amazon.

I did the math, and the case size below gives you the lowest price per oz for this water (click the link to check out the current price):

You also have the option to take advantage of Amazon’s Subscribe & Save with Penta water. This option allows you to set your own schedule to receive Penta water automatically each month. You save 5% on the first case and 15% on each case after that.

It’s also eligible for Prime free two-day shipping.

Now that you know the pH of Penta water and where to buy it in bulk, let’s see what current drinkers are saying before I share my review with you.

Penta Water Reviews

Is Penta’s acidic pH a bad thing? Well, this question is open to debate, but I’ll tell you right now that I wouldn’t buy this water because I wholeheartedly believe in the healing power of alkaline water.

Read my story to see how it helped me reverse a chronic case of heartburn and fatigue. I drink it every day and will continue to do so for the rest of my life.

Now that I got that out of my system, what are current Penta drinkers saying? I will say that the Penta reviews on Amazon are sparkling.

Here’s what I found:

  • One guy said Penta water has helped his whole family stay healthy and out of the doctor’s office. They began drinking it after his doctor recommended they try it. He called it “so worth” the price.
  • One woman made a bold claim, writing that Penta’s “viscosity” allows it to easily pass through “cellular walls.” She didn’t link to any scientific evidence to back up her claim.
  • Another person said Penta doesn’t cause bloating like other water brands.
  • One woman over 60 wrote that Penta gives her an immediate energy boost.
  • Another person called it “so refreshing” with a “different” taste than other bottled water brands.

After checking out the Penta water reviews, I must say that I’m a bit suspicious of some of the health claims I came across. A lot of reviewers went into great detail about how Penta water hydrates better, and they made scientific claims that appear far-fetched to me.

My Penta Water Review

Okay, I’m kind of excited right now because I feel like somewhat of a sleuth after looking deeper into this bottled water brand.

I’ll break my review into two parts to make it easier for you to read: my likes and my dislikes.


  • I do think this water is super pure since Penta uses reverse osmosis filtration to remove impurities. You can be sure you’re drinking purified water when you buy Penta.
  • It’s fluoride-free.
  • The bottles are BPA-free.
  • Penta’s water source is an aquifer in California.
  • They provide a water quality report on their website. I do appreciate when a bottled water company is transparent.
  • They use 100% solar power.


  • The wacky health claims that appear in the Amazon reviews. I have yet to see another bottled water brand with reviews like these.
  • Here’s why I feel like a sleuth. On Penta’s Amazon product page, the company lists a “naturally occurring” pH of between 7 and 8, which would make their water slightly alkaline. The video above shows that Penta water is acidic. Here’s the most interesting part, though. I checked out Penta’s water quality report, and the pH on the report says 5.9. Where did they get the natural pH of 7 to 8?
  • The TDS is too low for my taste. I do prefer water with a higher pH and lower TDS, but not water with a TDS of 1ppm. Yes, there are no impurities in Penta water and also no essential minerals.
  • They say the water is “infused” with oxygen. I do see that they use ozonation to sterilize their water before its bottled. Ozonation is a common process used by water companies to sterilize water with ozone.
  • I see a third pH claim on their website between 6.10 and 7.12. I’m really confused about what pH they want their water to be.

A Better Alternative

Penta water has a TDS of 1ppm. This means the water is essentially blank water. Who’s to say you can’t make Penta with a reverse osmosis filtration system that gives you the same TDS reading?

How to Make Penta Water

Click here or the image below to check out a reverse osmosis system that makes water with close to 0 ppm:

Reverse osmosis filtration is part of Penta’s filtration process. They also use UV light and ozone sterilization.

Click here or the image below to check out an ultraviolet light water purifier:

And last but not least, click here or the image below for an ozone generator:

Voila! Now you’ve made purified ozonated water with a TDS near 0ppm.

Final Thoughts

Almost everything about Penta water confuses me. Why do they get their water from an aquifer in Calfornia then proceed to strip all the minerals out of the water? Why not just use municipal water?

Then, there’s the pH confusion.

Overall, I don’t like to bash any company, but I have no idea what makes Penta water special.

The best two bottled water brands I’ve come across are Icelandic Glacial for alkaline spring water and Essentia for ionized water.

If you love Penta water, you’re better off making your own reverse osmosis water at home. In my opinion, the ozonation and UV sterilization is overkill since reverse osmosis does such a great job of removing everything from water.

There are a ton of home reverse osmosis water filtration systems on Amazon for very reasonable prices.
