Boiling water kills bacteria, but the water still contains all the impurities and farm chemicals from ground water and acid rain water, and wild fire retardant chemicals, a big concern of ours.
This lil pure copper stovetop distiller, called an alembic, a medieval scientific instrument, makes one quart of distilled pure water per hour, it only evaporates the pure water parts to steam, cools and catches it. Pure H2O water. Never any rust, it is all copper.

The distillation pan holds 4 quarts, 4 liters. It produces 1 quart, 1 liter per hour of luke warm distilled water, 3.8 liters total. Every eight minutes, the steam coil that turns steam into distilled water heats up and needs to be cooled with 2 liters of cold tapwater. By draining the heated coolwater in a bucket, we reuse, only takes one bucket, 5 gallons, 40 liters of cooling water.
