I have a Propur system, my friend has a zero water system but recently bought a propur system, and TDS tests on the propur system show HIGHER tds readings AFTER the water is filtered on both mine and his propur systems. I have the additional fluoride filters on mine and it doesnt seem to make any difference. Of course the zero water system always reads 000 after being filtered.

 

Can anyone explain this ?

Could propur be a scam ?

How important is a TDS reading ?

  1. I think the main question to answer would be how beneficial / dangerous TDS are, and the only way to do that is to get the water analyzed to see *what* the TDS is actually measuring. Zero water takes out everything that conducts electricity, be it good, bad, or indifferent. Per the propur documentation, they leave in minerals, which means by default it will conduct better than zero water. That doesn’t in and of itself mean the water is worse. In fact some say water with zero minerals is actually worse for you. I’ve used zero water for years but am now switching to propur.

    I know when I measure my post filter zero water, I show 000 on the TDS meter. However when I use the same meter on the propur I show ~89-91. My tap water actually measures in the low 80′s, so the TDS actually goes *up* after filtering. This could mean anything, but without before and after lab annalasis (spend $$), all you know for sure is that there was a change.

    @John – I think you actually have a problem with the set up of your system. I’m just guessing from my recent experience (just bought a propur since they want to “upgrade” our public water with all the new federal stuff).

    1) you may have a leak. (you can do the food coloring test to verify this fairly quickly)

    2) you may not have run enough water through to clean out the initial junk in the filter. There IS initial junk in the filter, which is why they recommend running two pots worth through (I recommend more due to paranoia below).

    When I first set mine up, I used just the top pot on the wire rack to ensure I got everything together right without leaking. I didn’t. It leaked like a sieve. I found that the instructions on the new filters are *wrong* in my opinion. The rubber gasket should go between the filter and the bottom of the pot (inside the top pot), NOT between the nut and bottom of the bot (outside the top pot). With the nut in the wrong place, no matter how tight I tightened the filter nut (even using pliers), I could see water leaking down the outside of the stem sticking down from the hole. Once I moved the washer to inside the top pot the leaking stopped with just finger tightening the bottom nut.

    Odd finding: when first running water through just that top pot testing for leaks, I used tin foil to direct the water from under the wire stand to the sink (improvisational engineering). After I fixed the leaking I thought I was good and just left it like that to finish running the initial water through to clean out the filter. I got a shock when I came back hours later.

    Whatever was coming out of those filters for that first pot was strong enough to actually oxidize the tinfoil. I kept the initial foil and a mid-stage foil, and you can see the dark coloring around the impact point and along the streams to the end of the foil. It took 7-8 pots before the tinfoil stopped visibly changing colors (I kept changing it between pots).
    I have a pic, but don’t know if it’s allowed.

    • ergh, besides my usual spelling errors, there’s a serious error here I had to correct:
      With the nut in the wrong place, no matter how tight I tightened the filter nut (even using pliers), I could see water leaking down the outside of the stem sticking down from the hole.

      That *should* read: With the *washer* in the wrong place

      Heh, it tells you to put the nut in the right place. The problem is the picture shows the washer going on the bottom outside, *and* the text reads: “Install in upper container with washer and wing nut on bottom side of upper container.”
      I could NOT get it to not leak using that method. Maybe someone can offer a suggestion if I’m doing something wrong.

  2. Yeh Ive just bought a Propur system here in London and the TDS BEFORE filttration was 350ppm, and after was 330ppm. I was expecting amuch lower figure around 50ppm as expected from a 4 stage reverse osmosis filter with added mineral unit. That is what I have installed under the sink !!, and 50ppm is what I get after mineral addition (15 straight after 4 stage RO).
    I thought propur units were suppsoed to just leave in the minerals, NOT add any of its own. Can anyone clarify this please ??

    Cheers

    • I dont know, it seems that no one will come forward with an answer to this, i did however order the new ceramic Pro-one filters, when they get here i will see how the fair on the TDS meter.

      but Im thinking more and more that pro-pur is kind of a scam, my water actually comes out with a higher TDS reading after its filtered through my pro-pur.

      IF Anyone can give insight to this PLEASE RESPOND !

  3. I understand the fact that Propur leaves minerals in the water, and I understand TDS readings are not necessarily a red flag but more of just a reading of stuff in the water, but why would a tds reading be higher AFTER the water is filtered, that would indicate to me that the filters are leaving even more stuff in the water than what I began with.

    • You definitely ought to contact Propur and see what’s up. I thought you were saying that you were comparing Zero Water filtered water with Propur filtered water. My mistake.

      That clears up everything. TDS meters also measure ionic conductivity within the water. This website explains it with the technical jargon that I lack the eloquence to utilize effectively.

      If you’re still suspicious, contact Propur. If that gets you nowhere – I guess request a refund.
      Regardless, when and if bottled water skyrockets or for some reason there is a shortage, I’m breaking open my Propur. Says no priming required, but I’ll probably flush it out good before using it based on what you are saying about the TDS. Oftentimes, if a water filter isn’t flushed appropriately, this can also be a reason why the TDS is higher.

  4. Propur is not a scam. In his commercials on his show, for Propur – Alex states that it leaves in beneficial minerals.

    TDS measures a broad spectrum of ‘total dissolved solids’ which can be anything from beneficial minerals to actual junk that you don’t want in there. So a measure of TDS is not necessarily a red flag that there is junk in there. It is likely the minerals that Alex Jones states the system leaves in. Many water filter companies explain that their filters do this.
