Water distillers treat and disinfect water for drinking, cooking and other home or commercial uses. Choosing the best distiller for home or industrial use depends on your estimated water use and personal usage preferences. Distillers come in various sizes and models. For home use, countertop models are available that plug into a standard outlet or can be connected to your water supply. These come in manual or automatic. Industrial distillers are also available that run on 120V normal household current.

Batch Distillers

Batch distillers come in countertop or floor models. These are the best home distillers for drinking water because they are small and easy to use. Countertop models are small, about the size of a coffee maker. With batch distillers, water is poured directly into the boiling chamber, the unit is turned on, the water boils and is evaporated into a storage chamber. The machine automatically turns off and the water is filtered for drinking. The countertop distiller can purify 1 gallon of water per day. If you drink more than 1 gallon of water per day or wish to use the water for cooking, batch distillers come in larger 10-gallon floor units.

Continuous Flow Units

The best dilation units for industrial or business drinking water use are continuous flow units. Businesses and industrial plants have numerous employees and need a larger volume of available drinking water. Continuous flow distillers are automatic units connected to the water supply. Water flows into the boiling chamber and is maintained by a float valve. The water is distilled and stored in a storage tank or sent directly to the use area. As the purified water level drops, the unit automatically turns on and fills the storage tank.


Distillers remove contaminants, but also calcium, potassium, magnesium and other trace minerals that are beneficial for health. Essential nutrients and trace minerals can be obtained from foods. If you eat a well-balanced diet containing a wide variety of fruits and vegetables, this will not be a concern for you.

Distillers vaporize volatile organic chemicals, also called VOCs, and distiller units may purge some steam and volatile chemicals into the air, according to the University of Arizona Cooperative Extension. Home Distillation units should be properly vented to prevent indoor air contamination.
