24/7 Espresso Services highly recommends a water filter or water softener to be fitted to any plumbed-in coffee, vending machine, hot water boiler, or water cooler, to prevent the build-up of lime scale, eliminate odors, remove bacteria & much others.
Filters should be replaced: annually, quarterly or biannual - depending on the Manufacture and model recommendations and usage, if you do follow this our advise, you will prevent damage to your machine and warranties becoming invalidated.
