I have never seen a consumer system (in person) or a water store using a D/I stage. (This isn't to say tons people have them installed...)

The water you can buy from the grocery store only goes through a carbon and an R/O stage (if you're lucky!, sometimes it's just carbon!).

The water you buy from the "pure water store" goes through multiple carbon stages, UV stage, then R/O, etc.

All the bottled water you buy (Dasani, etc) doesn't go throgh D/I, as per the mineral content listing. If it did, there wouldn't be any minerals to list.

With our newborn we keep a juice pitcher next to the kettle and just boil a couple litres of tap water each morning and then once it's cooled down, we fill up the juice pitcher. Then this is used for formula water throughout the day. Just ensure to clean the pitcher every now and then.
