Large Capacity & Production
For home or small office use, the Mega Classic produces up to 12 gallons of fresh distilled water daily and stores 10 gallons of water in its stainless steel storage tank. Because this is an automatic distiller, once water is consumed, the unit turns itself on to produce more fresh distilled water. The Mega Classic will make enough water for a large family or small office daily.

Built-In Pump
The built-in pump on the Mega Classic allows it to conveniently deliver water to a dedicated kitchen spigot, pot filler, icemaker, and refrigerator from a remote location such as a basement, laundry room, or garage (depending on local conditions). The flow rate is 1.4 Gallons-Per-Minute and produces 45-60 PSI. It also includes 25 feet of tubing and a faucet.

Automatic Drain
The automatic drain feature helps keep your distiller free of buildup between cleanings and flushes the boiling tank after the storage tank is full. A drain is required to use the automatic drain feature. For installations that cannot accommodate a drain, the unit can be switched to manual drain mode.

Long Lasting & Durable
Made in the USA, the Mega Classic has the best warranty in the industry. We use 304-grade stainless steel and with regular maintenance, the average life span of a Pure Water distiller is 20+ years, and some distillers have come into our service center that are over 40 years old! Moreover, we carry parts for our distillers in the event that it requires maintenance. Pure Water has been making water distillation systems for over 50 years for families, businesses, embassies, hospitals, schools and more.

Emergency Use
Natural disasters are becoming more frequent. Even if the power goes out, you will have 10 gallons of distilled drinking water in your storage tank. Moreover, with the Mega Classic’s high output, you can easily store additional water for later use.

Secure & Safe Water Source
If there is a boil alert, water main break, chemical spill, or other disaster, you can rest assure that the Mega Classic is removing contaminants before you hear about it on the news. Our distillers were originally developed for rural people and farmers who had issues with nitrates, pesticides and other chemicals that would find their way into well water. Now with microplastics, pharmaceuticals, PFAS and glyphosate, having a water distiller is more important than ever.


  • Cleaning the boiling tank approximately once a month
  • Replace the carbon filter approximately 3-6 months
