RO/DI users....
How many gallons of use do you get out of your DI filter on average? The water comes out at 8ppm out of RO and 0 out of DI, so DI is pulling about 8ppm out... just trying to estimate the change out time... thanks...

With a good well packed 20 oz vertical cartridge you should be able to get 300 to 400 gallons or more unless you have high CO2. CO2 really knocks the DI life down.
