    WAter filter~ Brita

    http://www.brita.com/us/products/wat...sers/ultramax/

    Think this will work ? I think it said "good for plants" but they probably don't know about our plants :P

    Nope, Brita filters remove very little in the way of TDS.

    Yup. Reverse osmosis is a complex process, Brita is not RO. If it was, people wouldn't be spending so much money buying distilled water or RO systems. You could always try building a solar still.

    Actually, while we have always said that brita is not sufficient... I've taken a moment to look at this system and I think it may work for our application. It says it filters by activated charcoal (which we all know does no good for minerals) but it also has Ion Exchange Resin which I'm pretty sure is deionization..... This is generally the final step of a good RO system to get the TDS from 11ppm or whatever your system may finalize at, down to zero. Without having something do an initial drop of TDS, this filter will fail quickly- which is proven by the literature given with that product.... 40 gallons to a filter, of course that will vary depending on your TDS levels to start, the higher they are the faster the filter will fail. So you would definitely need to constantly test your water with a TDS tester so you know when it is time to replace that filter. That given- I don't know the cost of those filters and if this would make it unreasonable to use in our application. but on a "can I use it" scale... I give it a "I'm pretty sure you could" lol

    While by no means conclusive, I found this little thread in a google search: http://www.window-tools.com/windows/...e;topic=4202.0

    Here's a pitcher that claims to be so good, it gets the TDS to 0. I'd love to try it out sometime.

    I tried a new brita filter on our tap water a few months back. TDS on tap was 490 ish, after brita was 450.
