Water DistillerMegahome's water distiller distills 1 gallon every 5. 5 hours. Distills the water at 212 degrees Fahrenheit which is the proper temperature for removing unwanted toxins and contaminants. It also includes 6 (optional use) high quality activated charcoal filters. The optional filters are used when VOCs like chlorine or other toxins that can form into a vapor are present. The filters capture and remove these toxins during the distillation process.
