YOUR SAFETY COMES FIRST: This Megahome distiller is UL (Underwriters Laboratory) approved. UL is the trusted independent global safety science company for US products, and determines product compliance with stringent safety standards. PLEASE NOTE: For fire safety, many home insurance policies require that electrical products installed in the home be UL certified. Megahome distillers are one of the only UL approved water distillers available. BEST QUALITY: Full 304 stainless steel interior and exterior, including the boil chamber, upper steam dome, and stainless condensing coils. Water does not touch plastic. PUREST WATER: 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. GLASS COLLECTION: This distiller includes a durable and easy to use porcelain lined nozzle, and a glass collection bottle. This ensures the purest and safest distilled water for all of your needs.
