Please help me answer the following question that arose today. I have a 5 stage 150 gpd RODI system that gives me 0 TDS (which i paid $270 for)http://www.airwaterice.com/c=hyQ6iB...RODI-with-Gauge-TDS-Alarm-Dual-TDS-Meter.html.
Today out of curiosity i went to my brother and tested his water coming out of Tap Water Filter (very small and simple device for $50) http://www.marinedepot.com/Aquarium...icals_API_MARS_Fishcare-AP4111-FIRODI-vi.html

And to my amazment that water came out to be 0 TDS. I am baffled by that discovery and trying to figure out why RODI systems are better. All i hear about good water is 0 tds and no other parameters, however both devices giving me 0 tds.

What am i missing?

That your 'real' rodi will process many, many, many (did I say that 3 times? :)) more gallons of water and still have a TDS of zero, while he will need to replace the cartridge portion of his a LOT more frequently than you.

i use the api tap water filter and have for years. i get about 200-300 gallons per filter. i also live in nyc and the tds in my source water is only about 12ppm. YMMV
