I was wanting to know what would be the best RO unit to get and what to look for when I buy one also how much of the water goes to waste when I use it. How often do you need to change filters. Is there any one that has a used one they would sell. Thanks
the one i bought recently i got from thefilterguys.com . it came with an duel tds meter so you can check the tds in and out and determine when to replace the cartridges. i havent hooked it up yet but it looks solid and well constructed.
I think it is actually http://www.thefilterguys.biz/ and I would recommend them. I had several questions when I bought mine, and they were more than willing to answer them.
I have made two or three orders from the Filter Guys and highly recommend them. They do excellent work.
