The DI can be an important part... now days it seems the RO/DI units and RO units and about the same price anyways.

using R/O is somewhat better than using plain tap water, but you need to have the D/I. Without the D/I, you're only getting rid of (about) 91-94% of your contaminated H20.

The Typhoon III is a nice one...
A RO is MUCH better than just tap water... cleaning 91-94% is pretty good... but adding a DI will pickup the remaining stuff.
