Has anyone does cost analysis of how much it costs to maintain the average RODI unit a year in filter replacement costs? I buy water weekly from "Water to Go" in Federal Way. They have giant RODI unit that supposedly makes A1 water. I buy the 100 gallon prepaid card so it costs me 44 cents a gallon. At 10 Gallons a week= 520 gallons = $228.00 a year for RODI water.
If a RODI system costs 200-300 and has a 5 year lifetime thats roughly 40-60 a year in initial purchase cost, so if I had to spend more than 160 a year in filter cartidge replacements I would not be saving by having my own RODI. I would of course save the hassle of having to stop at WTG every Friday on my way home from work.
