RO will only remove 96-98% of the TDS so it all depends on your tap water quality. Without a TDS meter you never know. RO by itself is also poor with phosphates, silicates, nitrates, ammonia and other things. For the little bit extra DI is safe insurance.

You'll want the extra verticle DI canister. The small positively and negatively charged ions (cations and anions) in your water supply that get through the filter and RO membrane will get pulled out of the water when they go through the DI resin. If you get the color changing resin and a clear housing, then you'll know when it needs replacement. Your TDS will be lower using both RO and DI.

I buy walmart ro/drinking water and use no di and have no issues but have been thinking of pumping it through a di unit only to see if would cut down on my daily glass cleaning.......
