Durastill8 Gallon per Day Automatic Water Distiller Including 10 Gallon Reserve Tank with Casters and Level Gauge - Deluxe Model 3040

I've owned this model Durastill distiller since 2002. It has provided me almost 22 years of contaminant free distilled water. I've used it on well water as well as with chlorinated / fluoridated municipal water that is extremely hard. The distiller removes it all. The TDS readings range from 1ppm to 5ppm depending on how new the pre and post filter are. I change them once a year. Draining the boiling tank is very easy as is cleaning out the scale build-up. I use food grade citric acid bought on Amazon to soften up the scale build-up prior to cleaning. Having it hooked up to a cold water supply and using the auto fill mode insures that I always have 10 gallons of distilled water at all times. Made in USA of stainless steel.
