EasyStill is based on the same design as a well-known distillation unit for potable water. The chlorine release valve is omitted, the heating element is changed and the cooling capacity is enhanced to deal with alcohol. Separation is improved and gives a very pure spirits. It is still possible to distill water with the unit but takes twice as long as with the original water-distilling model.
The Invoice also specifies the unit is a distillation unit for water. Certain administrations demand that the description on the invoice must be the same as on the packaging. So in order to conform with the regulations and not cause hold-ups in customs in countries outside the EU (within Europe there are no customs) the invoice in the package has the description Drinking Water Distiller.
