DI water

what is the TDS in your area (there probably are TDS testers at your lfs)? that will tell you how clean your water is. high number bad, low number good.

In vancouver our TDS can be as low as 7ppm i believe. on the other hand i think there was a case in calgary where it got to 200ppm. if the TDS is low, the AP tap filter works fine and will last long (i use it). if TDS is high, then you might want to look into getting an RO unit yourself.
