Espresso machines require water with virtually no scaling minerals to operate reliably and efficiently. In the past, operators have used softeners that had to have salt manually added periodically. Most often this was overlooked, simply because of the inconvenience, until the repair man was presenting the bill for de-scaling the boiling chamber. Using Omnipure water filters, our EFS Espresso Water Filter System eliminates the messy and time-consuming task of pouring salt, backwashing and rinsing. In less than a minute the Omnipure EFS softening and taste/odor cartridges are changed and the system is back in service.
