It depends on the hardness/mineral content of your water.  I get to fill my 
45 gallon reserve tank twice, and make a couple pitchers of iced tea with one 
cartridge.  I usually have about 120ppm GH.  In February when the aquifer 
fills up, I can get three tanks, or about 135 gallons.  Hardness then is down 
to 50-60 ppm.

I have decided to buy two more TWPs and some rechargeable resins.  Then I can 
fill one used cannister with KATI, one with ANI, and the third with activated 
carbon.  I'm going to run them in series, first carbon, then KATI, then ANI.  
This way it will be cheaper over the long term, and I can buy it a little at 
a time, rather thn popping the big bucks all at once for a rechargeable DI
