As any CPAP user knows, you become a distilled water junky! The humidifiers attached to the CPAP can go through a couple of cups of water a night during dry weather. As a member of the Geezer Squad, dealing with the heavy bottles from the supermarket/drugstore and the ever-increasing prices make a home distiller a sensible purchase. The price for this unit is great and the only difference with more expensive models seems to be the exterior finishes. I’m running my first batch and so far, so good. Setup is simple, except for inserting the charcoal filter into the exit spout, which is a bit fiddly. I finally got the hang of it. The rest is just plugging in the two cords, filling the tank, and plugging it in! It supposedly can process a gallon every 4 hours and it takes about 30 minutes for a fresh tankful to boil and start dripping into the external jug. There is an auto-shutoff feature that turns off the distiller when the tank runs dry, just like some coffee makers. So you can let the machine run while napping or sleeping without worrying. The unit isn’t tiny but it’s compact – taller than wider. It doesn’t have a large footprint so I have it doing its magic on the bathroom countertop next to the sink and it’s working fine. I’ve still got a couple of empty supermarket jugs so I’m going to fill them with water from the machine, which should give me nearly a month’s supply for the CPAP. So, good price, easy to use, and my nearly 80-year-old self won’t have to juggle heavy bottles from the store, especially in bad, slippery weather!!! I’m not planning on drinking the water because distilled water is flat and tasteless after the machine removes the minerals that give drinking water its flavor. But it probably does make good coffee or cooked foods in places where the tap water has strong or unpleasant flavors. Cleaning the distiller is basically running a batch of diluted citric acid (supplied) through the unit periodically – whenever you see scale forming in the stainle
