Totally stainless steel with glass carafe.
The hardest part was assembling the glass carafe. You have to put the stainless steel bands around the carafe, attach handle, and screw it in securely.
Easier to operate than a coffee maker. Just fill stainless steel chamber with gallon of tap water. Use hot water from faucet to save time.
Put on the top which contains the cooling fan. Put glass carafe under drip spout. Plug in electricity and press RESET button.


Distilled my first gallon of water during the night. I was shocked to see what was at the bottom of the distiller. Bright orange fluid.
Who knows what chemicals are in the orange fluid? But I'll never drink tap water in my city again. And I'll never put tap water in my ResMed H5i Humidifier either. Just think of the chemical vapor I'd be breathing. I'd run my xPAP without humidifier if distilled water is unavailable.

The distiller takes about 4-5 hours to distill a gallon of water. Just setup and run while you sleep at night. The unit turns itself off automatically when finished. In the morning, you have fresh, pure distilled water in the carafe. Easy cleaning if you do it after every run. Just put 2 drops of dish soap and a little tap water. Through wipe with a Scotch-Brite. Rinse with clean tap water. Dry with soft cloth. Do the same for carafe. Add a gallon of tap water to start next batch.
Next I'm going to distill a gallon of "Purified bottled water" like Aquafina or Dasani (bottled by Pepsi and Coca Cola) to see what it contains.
The source of these brands are Municipal tap water which has been "purified" by reverse osmosis.
Any chemicals with molecules smaller than the pores in the membrane on the RO unit will end up in the "purified water." I have not been able to find any information about the membranes used by Pepsico or Coca Cola to purify their water.
BTW. My dog and cat LOVE drinking distilled water. No nasty chlorine or chemical taste/smell. My cat is drinking about 3 times as much water as she used to. My dog is drinking twice as much as he used to. Drinking distilled water is a natural chelating agent. Instead of "leeching minerals from bones", it can dissolve calcified plaque in your arteries preventing hardening of the arteries. What could be more natural than providing you body with the purest H2O available? It flushes out toxic elements from your system. I'm a total believer in drinking only distilled water.
