Re: tap water filter i think its about the same thing. that you would have to read into tho. an RO unit will produce more water with less work then a refrigerator water spout. the majority of those membranes are only good for a bout 100 gallons, and thats because they dont purify the water to the extant of an RO system. RO units dont have to be expensive or complicated, but if its something thats not in your budget, then the cheap 1 gallon deionized water at the store could be used i believe. that will get expensive really quick though. |
