Yes, you can. I have been doing it for years.
You need a steam water distiller. It can produce up to 4 litres of distilled water.
The machine boils the water until it turn into steam and goes into the pipes.
The contaminants in the water are left in the bottom of the tank.
Look how dirty it is !
A fan above cools the pipe and turns the steam into droplets of distilled water,. It is collected in the glass container.
The water distiller cuts off the power automatically in about 7 hours. The hot distilled water will cool down to the room temperature.
Where can I get the above steam water distiller ?
