Q&A with Jeff Kiszonas: Swapping deionized with reverse osmosis

Q - Can Reverse Osmosis water be used in place of Deionized?

A – This would not be feasible. Reverse Osmosis (RO) removes particulates to a sub-micron level, but really does not control pH or conductivity levels.  The machine could be filled or “topped off” with RO water, but it would still need to go through the de-ionizing resin system for pH and conductivity control.  RO systems are also somewhat slow in filtering. The best practice is to fill or top off the water levels in the machine with whatever clean water supply is at hand, and use the resin system for operational control.
