ROVSUN 【Upgraded】 1.1 Gallon/4L Water Distiller Countertop Distilled Water Machine with Flame-Retardant Material, BPA-Free Container & Stainless Steel Interior, 750W Distilled Water Maker Purifier

This distiller is slightly larger than many, but what attracted us was the on/off switch for AC power. No need to pull the plug to power down. It runs quietly, and was easy to clean up after use. We liked the plastic catch container - no glass to break! Our use is in a humidifier to avoid the white dust, and occasionally in an iron, etc. We do not use the carbon filter, which keeps things simpler, and particularly like the short flexible tube that can be attached to the spout to ensure all the condensate is directed into the catch container, and not dribbling off the edge of the lid with a slight misalignment. A tube of this kind could be added to similar distillers if they don't include one.We ran it on a Kill-A-Watt meter and were surprised to find that it consumed almost exactly the 900 watts at which it is rated, peaking briefly at about 905 watts, then settling down around 890-900 watts. It took about 3.7 kilowatt-hours to produce approximately 1.33 gallons of distilled water. (Note that we do not operate it at "full capacity", from fill line to dry - see next paragraph.)We avoid the overheating shutoff by measuring the capacity of the distiller just below the fill line (where we fill it), and note that level on the catch container. We power it off when the distilled water has filled to an inch or two below that. This leaves an inch or more of water in the bottom of the distiller. By not boiling it dry, we avoid depositing a lot of minerals in the bottom of the distiller stainless steel pot, and also avoid distilling over any small amount of heavy volatiles that boil at a higher temperature than water. We intend to plug it into timer switch capable of switching the 900 watt load, so allowing it to run without checking its progress. It is pretty reliable in timing, if started with the same amount of water, at the same temperature. We use hot water from the tap (actually just warm, as we keep the water heater set low), and our water is softened, which helps avoid lime scale. A cleaning with vinegar removes nearly all the "staining" we get in the bottom of the distiller pot, leaving only a faint stain that penetrated the surface of the steel right away, but is not really darkening with repeated use.Starting with hot water shortens the time before it starts boiling and producing condensed water. This water is heated with natural gas in the water heater, more cheaply than heating it with electricity in the distiller. Leaving some (hot) water in the bottom at the end of each use wastes the electricity used to heat it up. We are talking a few cents here, either way. At our electrical billing, I recall calculating the cost of distilled water at about 30 cents per gallon. (Forgive me if the power usage and cost data are a bit off, I am going from memory.)We are quite happy with this ROVSUN 6L distiller, and can recommend it. Our usage method was inspired both by our own ideas and the reports of other reviewers (thanks to all for reporting your experiences). Operated with a little care, it works fine, does not leak, and is easy to clean.

This unit has been great so far- I run a decent sized humidifier in my studio, and this is preventing me from buying multiple gallons of distilled water a week. The water from it is working great for the humidifier without leaving any mineral buildup or white dust. It's straightforward and simple to use, and cleaning with the included citric acid is really easy. I've been running it a couple of times a week, and cleaning it about every 5 cycles. The included jug feels sturdy. Overall, it's a little loud, but sitting on my basement counter it doesn't bother anyone. It's a little larger than I anticipated, so when I'm not using it during the colder months I'll have to figure out a place to keep it besides the counter.

Been using it for a month. Works great! Tested thw water and it is distilled. Has a little bit of a burnt taste due to the last of the hard water boiling off and burning the solids in the water.

I wish I had chosen this brand the first time. I recently had to replace my old water distiller that I bought 3 years ago that was 4 TIMES (you read that right) the price as this one! I was upset that I spent so much money on a product that only lasted 3 years, so I abandoned that brand and found Rovsun.It looks nearly identical to the one I replaced. Main difference is the on/off switch in the back which is so convenient because I no longer have to plug/unplug to turn it on and off. I also love the stainless steel spout on the Rovsun compared to the plastic spout on the one I replaced.Distillation takes the same amount of time, which is roughly 6 hours.I should add that some reviewers complained about the PPM readings. Distilled water should be 0.5 PPM or less to be labeled as "distilled". But you need to keep in mind that not everything can be removed through the distillation process alone. You need to filter as well to remove particles that can't be removed from distillation, hence the filters they provide for you inside the spout. They're easy to change out. Just be sure to change them periodically. Changing them depends on how frequently you use your water distiller. Personally, I change mine monthly.Overall this is a great, inexpensive, water distiller. Highly recommend!

Great product that does its job very well. My wife uses a cool mist humidifier and for a couple years I've been buying gallon jugs of distilled water at the grocery. Not any more as this distills your tap water and gives you a gallon of clean, mineral free water for optimal use in your humidifier. (Never use tap water in a humidifier as the minerals will gum up the inner works of a humidifier. After it's use, you simply fill it with 4 tsps. of Citric Acid for water distillers and plug in the bottom section. In 30 minutes, the inside of the distiller is bright stainless and clean, ready to make more distilled water.
