Antique Nature's Method of Purification Water Purifier

This vintage water purifier is made by National Percolator Company, Nature's Method of Purification. The "Duplex Water Percolator and Cooler" is made entirely of ceramic, except for the spigot. It has two separate compartments that are designed to be stacked. You add the dirty water to the top container, properly close the lids, and let the water settle. The liquid then drips down into the lower compartment, leaving the impurities behind. As the clean water drips down to the lower level, the container fills, and you can access the clean water through the spigot. Directions are printed on the front of the purifier making for easy use.
