    Most of the brita filters are just the activated charcoal filters... which is why we've always said they won't work for our plants. But this particular one says it uses Ion Exchange Resin... Which is exactly what that other one that Jason found uses "the ZeroWater system uses a five-stage ion-exchange filtration system" So on this particular brita filter.... I think I'm sticking too "I'm pretty sure you could".

    2 stage brita faucet filter: stage 1: A non-woven screen around the filter to trap sediment. Then the water flows through stage 2: A compressed block of carbon and zeolite, reducing chlorine (taste and odor) and lead. **no good**

    brita pitcher filter: The Brita® Pitcher Filter contains activated carbon and an ion-exchange resin. **probably good**

    From my understanding there are diffrent ion exchange resins that exchange for different products in the water, but since this is made for water purification I would have to say it's the same kinda at the end of a RO/DI system (plus I think water purification is the most common use of ion exchange)

    From my research (especially with reef tanks), this is one of those subjects where the more you pay, the better the product is going to be.

    Sorry to say I use these filters for my drinking water. Testing with a TDS meter it cuts the TDS by about half:

    Plain Tap water: 275 ppm
    After filter: 156 ppm

    This is probably ok for Nepenthes and Mexican Pinguicula but I wouldn't use it for other Genera.

    So it depends on what your TDS of straight tap water is. It also depends on what those dissolved solids are too - these filters do not filter out some. Be aware also that in Southern California your municipal water supply may come from many sources and the TDS will vary depending on the source at the time of testing.

    Filters run about $8.00 each. Capacity is around 40 gallons. So think around $0.20 per gallon.

    Thanks NAN- always good to see first hand Ever tried running water through a couple times? More contact with resin should yield more pure (less tds) water. Still seems like too much work though LOL

    If too much work is to be done to save money, I'd rather do it than annoy my parents almost every couple days. "Mommmmyy, can we go buy water now?"

    So my parents bought the filter to stop that... :P

    brita is all i have ever used. although ive always wondered if either RO would give me better results, or if my tap water is fine.

    The only way to tell is to have your water tested.

    I haven't tried refiltering the water to see what effect it has but then you'll be lowering the capacity of the filter too so think $0.40 per gallon.
