Thanks everyone. I'm definitely looking into buying an RO system as lugging 40 gallons worth of water upstairs to my condo doesn't seem appealing to me LOL. I have an attached PUR water system that hooks onto my faucet. Doesn't do a thing according to my TDS meter. I'm probably going to buy a tankless RO system and fill a 40 gallon tote or something and make sure I don't leave or forget about it while it's filling...
