I can recharge the DI unit, the unit with a spare cartridge is $50 (give or take). So convince me RO/DI is better....

3 years on my membrains and filter changes of 5.00 ever 3 months. so that is on a 320gpd set up so I can pound out about 5 gal of RO in about 22 min. in an emergency in 4 hours I can do 60 gal of ro water.

I worked it out a couple weeks ago for a friend looking at getting an RO for drinking water instead of buying water and it cost me less than $.05 to make 5 gal of water. so lets say you buy a TWP at 50 bucks cuz you don't want to play with asid. they tipicly make 400 gal I believe around here. that works out to $0.625 for 5 gal so even if you get 1000 gal out of yours that is going to be $0.25 for 5 gal now if you recharge how much does tha asid and your time cost?

Another big factor is speed, you run water to fast through a TWP and it doesn't do its job properly.

at any rate I use my RO for drinking water and for the tank so cost/gal is cheeper over the long run even after the inital cost.
