About this item
This appliance uses a 750-watt heating element to distill tap water, reducing dissolved solids and other impurities to produce water suitable for drinking, cooking, or use in small appliances. The interior components that contact water are stainless steel, while the collection pitcher is BPA-free plastic.
It runs as a freestanding, corded unit and shuts off automatically once the water reaches 300°F or the water level drops too low, at which point a reset button restarts the cycle. Output is rated at roughly 0.3 gallons per hour, with a finished water quality around 2 ppm from source water up to 500 ppm TDS.
Beyond drinking water, it can supply water for coffee makers, humidifiers, CPAP machines, aquariums, or small engine cooling systems. An AC adapter is included with the unit.
