i bought a similar machine about 6 months ago and distill 4 litres about 4 times per week which is enough for 2 peeps for drinking water. i only drink distilled water now and think it is the best for health. When it's finished i pour into jugs and stir with a small wooden spoon to create a vortex to energise while singing a mantra to further energise.
i've not changed the charcoal filter yet (tested and it's 3 parts per million so pretty good) and don't notice any issue with taste.

i also add a pinch of Borax to each jug btw. Bicarb of soda is an alternative as Ura commented.
