Which Is The Purest Bottled Water?

Jun 6, 2011 by

Top Bottled Water


Several month’s ago I got a little water measuring device that came with the new Water Filter I purchased. The device measures Total Dissolved Solids ( TDS ) in the water ( it tells you exactly how purified water really is ). I have a post about it here.

Ever since then, I have been measuring all of the water I purchase (as neurotic as it sounds ).

When I was shopping in the store today I saw a lot of  overpriced Bottled Water and I wanted to investigate their purity.

In the end you can make a decision whether you are paying for the pretty packaging or great quality.

Just to let you know FDA requires Purified Bottled Water to achieve a TDS reading between 000 – 010. ( 0 being the purest, and as the number goes up, it’s the least purest )

Here is a list of the most popular Water Bottles and their measurement of purity on TDS meter:


Price 2.49 per 1.5 L  –  TDS  188

For a bottled water to read a TDS reading of 188 is pretty disappointing to me, especially for the price tag. Because Tap water is 210, and Pur Water Filter is 170.




Price 2.29 per 375 ml  –  TDS 031

This is not bad at all compared to the one above, it’s still a very expensive water. But this water gets more pointers with me because it comes in Glass Bottle, and you can reuse. A regular glass water bottle is around 10 dollars, and with VOSS it pays for it self.



Price 1.29 per 500 ml  –  TDS 111

As popular as this water is, I personally don’t think it’s worth all the hype, because there are a much better quality water out there for a smaller price.



Price 2.29 per 1.0 Liter  –   TDS 040

This is the first time I ever bought this water, and being the water fanatic that I am, this is nothing special.


Eternally Pure

Price 1.00 per 33.8 fl oz  –  TDS 048

As you can see it is also not the purest water, but the taste is not bad, the price is not bad as well compared to the other expensive water brands.



Price 1. 50 per 1.5 liter  –  TDS 034

This water is nothing special and not the purest, the price is OK for a large bottle, but there are better water out there for a better price.


365 Water

Price .79 per 16.9 fl oz  –  TDS 024

I actually like this brand because they provide a lot of organic produce for a smaller price. This water is very inexpensive and as you can see it more pure then the brands above.


Smart Water

Price 1.69 per 23.7 fl oz  –  TDS  021

Still not the purest, but since celebrities endorse this water it is the only reason why it’s so popular.



Price 1.19 per 20 fl oz  –  TDS 016

This water is actually one of the least expensive brands and it’s been around for a while. They also recently started recycling their bottles. So you get a good quality water and you are helping the environment as well.



Price 1.19 per 20 fl oz  – TDS 002

As you can see, this is the least expensive and purest bottled water. This was a big surprise to me, because I didn’t think the least expensive water would be the purest.



Price 1.49 for 16.0 fl oz  –  TDS 000

This water is the purest Bottled Water I measured  but as you can see it is also pretty expensive.
This water got it’s fame from celebrity endorsements and it also supposedly helps to grow your hair, and makes you skin glow. But in order to get those benefits you would have to drink a box of this water every day ( about 15 dollars worth ).

( BTW I am not promoting any of these brands, I am just investigating 😉 )

There you have it, as you can see just because a water is expensive doesn’t mean it’s the purest. And I personally prefer my water to be Pure ( I don’t want it to be enhanced with anything ) and I also don’t think it should cost you Arm and a Leg.

    Hi! There is a lot of information here, but perhaps some more elaboration may be required. The S in TDS is for ‘solids’. The purity of water is not determined by TDS alone. There are various other standards also, including microbial count.

    • Hi Vikas, Thank you for pointing that out 🙂

  • Zain

    TDS doesn’t simply represent impurities, it also represents Mineral Count:

    As stated in http://www.cleanairpurewater.com/best_bottled_water.html

    Total dissolved solids (tds) is the sum total of all the minerals in
    water. While minerals are desirable there is a range of suitability.
    Since tds is comprised of a number of substances, high levels will
    affect the taste of water and may also affect toxicity.
    Generally, a low tds is considered by some health practitioners to be
    more hydrating. EPA has set it’s Maximum Contaminant Level for tds in
    drinking water at 500 mg/l for aesthetic purposes. Water with a very low
    tds, say 30 or less, will have a sharp crisp taste, perhaps considered
    ‘clean’ by some. A higher tds, in the range of 150 to 250, provides more
    ‘mouth feel’ or ‘taste’.

    • Thank you Zain for the insightful comment and link, I enjoyed reading that post. It helped me understand more about water.
      I do prefer the cleaner taste with a lower tds. When there is a higher tds, water tastes a bit like metal.

  • Ohh yeah, I know what you mean.  I’ve only purchased it for the experiment.  It’s pretty crazy that some water bottles like Penta cost almost 4 dollars per small bottle.  Right now I am using a filter, it’s not so clean though, tap water has a funny taste and since I live in FL it’s a bit dangerous to drink it by it self.

  • Evaleen

    Ha! I bought a 32 oz Voss months ago just to use that bottle, so good advice! Makes a nice tall vial for cold water, 🙂 for just three buckers.

    And I’m definitely surprised with the low readings for the commercial brands (Dasani and Aquafina). I’ve had someone try to drill it in my head it’s the worst kind to get, that it’s just filtered city water or something… this person worries about everything though lol.

    • So far I’ve measured like every water brand I could find, and to my surprise the cleaner water comes from Publix ( the gallon one ), that says purified. I’ve been buying it ever since.

  • chixndopen

    1) You’re supposed to be reviewing purified water, so why are you reviewing source spring water that has not been purified along with it?

    2) Unfortunately, a purer water ? more healthy / better tasting water. Aquafina tastes like a dry & sterile chore, while Dasani tastes pretty much like tap water.

    3) It’s not the level of TDS (or lack thereof) that makes water taste good, or not good. The variable responsible for bottled water tasting good or bad, is dependant on which dissolved substances (minerals, gases etc) are present or not present, and the widely varying ratios between said dissolved substances. Different spring waters have different compositions with regard to minerals and gases, and taste different. Some taste horrible (usually no-name brand sourced from a well in a field), and some taste great (Evian, sourced from god’s vagina in france )

    Having said this, many of the minerals and gases present in water are beneficial / essential to health. You shouldn’t be trying to find water with nothing in it, but you be trying to find water with low levels of specific substances (lead, mercury, etc)

  • You are measuring bottled waters that include dissolved minerals in them such as Fiji and Jana so of course your cheapest waters like Aquafina and Dasani will be closer to 0, as they have nothing in them as they are PURIFIED water while Jana and Fiji and the like are Artesian Waters that have or add minerals to them for both health as well as taste. Your little meter is well and good for finding purity of water but have you considered that Pur and Brita do not filter out all the medications that cannot be processed out of city water? That would be one of my larger concerns over taste and TDS. Enjoy that 2nd and 3rd hand Depakote and Ritalin we’re cramming into our kids because they don’t excell well with sports or can’t sit still in a seat for hours on end in school.

  • John Parson

    Ummmm, buying Fiji water merely feeds the oppression and enslavement of said island–not to mention the bottles are made from some of the dirtiest and most polluting factories in China!!! So the whole bit where they try to claim that they are carbon negative is a farce.—BPA anyone? Maybe, just maybe if the island had access to their own water instead of having rampant water born disease problems I’d pay for some Chinese slaver to push a boat all the way to our continent. China is only good for cheap high powered lasers and all the crap “as seen on tv.”

  • Daniel Vondrak

    Just because a water has a lower TDS reading doesn’t mean that it’s “better”. In fact, a water withouth much mineral content is unhealthy. Ideally you want spring water with a healthy mineral content.

    • nigra truo

      That is very true. A low TDS is good, but a TDS of 0 is actually nothing special: Go to a hardware store and buy some distilled water and that is what you get. You have to remember that distilled water is mineral free, it is pure H2O, nothing else and our bodies over millions of years have never drank that kind of water and are not adapted to it. My chemistry teacher warned me about it in one of the first chemistry lessons, he said that you can kill yourself drinking too much of it.
      So I wonder how much glow you will have from it. If you drank 1 quart (1 liter) of that water, your stomach would actually pull the minerals and electrolytes out of your body into the water, though osmosis. That is the same process that kills you when you drink sea water (although there it is because there is to much salt in it, not too little)

      Unfortunately, TDS does not show what is there, which solids are disolved, and some are of course bad, you don’t want chlorine and flourine (who came up with that dumb idea to STILL put it into the water supply, now that we had it in every toothpaste anywhere for the last half a century?),
      but some elements in a TDS (maybe of 40 or so) can actually be good stuff, like calcium, magnesium etc…

      The good news is that soon we will get chemical analyzers that you have in your cellphone and then you can tell what is actually in there.

  • Rei Lapresca

    Thank you for posting the TDS of some bottled water available in the market.
    It is such a big help especially for me to calibrate my TDS meter unit that I use in my job as an Auditor (but I need to memorize the TDS for each brand that you listed…… lol).

    I can now calibrate my TDS meter whenever I am, all I have to do is find the brand of bottled water listed in your blog.

    Best Regards,
    – Rei 😉

  • Steve Morang

    Pure has nothing to do with the quality of the water and the TDS. Minerals are very important so the better European springs are full of them! Look for a water above 1000 TDS if you really want a health water! Taking them out through an osmosis process like Dasani is pathetic, but sells well to the masses as pure! Shame on them!

    • John

      Pure water actually has everything to do with TDS. High quality water doesn’t.

  • Rah Tha GoD

    It is not only about the TDS level of the water, it is about how it is produced, the content of the water location where it is taken from and last but not least the pH level of the water also. There are many other companies that produce water with better levels of taste and a high pH content that are not on this list that you can buy at Krogers and other whole food stores.

  • Trisha Idleno Morey

    Just so you all know Penta passes all tests for the purest levels of water. They are also the ONLY brand out of three in the world that are 100% open with their consumers about their testing process, results and hourly reports on how many times a day they test their water. I called them myself. They send me reports. They have been tested for transparency and are one out of three that are completely transparent with their product. Not just the water, but what their bottles are made out of. The only junky part about it is the price. It’s REALLY costly. Like $50 a week per person expensive. More if you work out. So if you want truly clean water, you can’t be poor, which I think is a pile of total bs.

  • The Waterboy

    TDS is actually good if high. Our bodies need minerals, total dissolved solids does not give you any information about the purity of the water. It just tells you how many dissolved solids are in it, it does not give you information on if the TDS are good or bad. For example, if essentia has 040 TDS that will not let you know what dissolved solids are in there. They could be good or bad (im sure they are not bad). Total dissolved solids are made up of organic and inorganic compounds. therefore, searching for water with low TDS can actually harm you. Distilled water will actually pull minerals out of your body and into the water, distilled water is “hungry water”, hungry for minerals. Although the reporting limit for TDS is 10 with the FDA, the actual reporting limit is only over 500, that means companies only need to report to the FDA if their water tests at over 500, not 10. I personally enjoy water that has a moderate TDS and preferably comes out of the ground that way, not out of a lab.

    • Dunsson

      I agree with you entirely. TDS is not the best measure, infact it is a secondary measure in many places, US and Canada included I think.

  • Sardar Ravinder Singh Rajan

    When we do purification process of water by reverse osmosis or demineralization than 99.5% of dissolved Solids removed during filtration. According to FDA Standard For RO water TDS not more than 10ppm or 10mg/l. But Many companies Sell their products by label “mineral water” and re-addition of Minerals for Enhance the taste of water and Full fill the Body Requirements.
