    When you start out the cheapest way to produce low volumes of pure water would be to use di resin, but as you start using more water it will work out more expensive as you will be buying more resin. That would be the time to buy a commercial reverse osmosis filter 4040, but you will still need the di to bring the tds to 0,but then the di resin will last for ages.
    Waste water from ro is good for gardening.
