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

I’ve been using the ROVSUN Upgraded 1.1 Gallon Water Distiller for a little while now, and I’m genuinely impressed with how well it performs. The setup was simple, the instructions were clear, and the unit feels sturdier than I expected at this price point. The distiller runs quietly, produces very clean‑tasting water, and the stainless‑steel interior is easy to wipe down after each cycle. I really appreciate the automatic shut‑off feature—it gives me peace of mind when I’m multitasking around the house. If you’re looking for a reliable, affordable way to get purified water for drinking, humidifiers, CPAP machines, or even aquarium use, this unit delivers exactly what it promises. Great purchase and definitely worth recommending.

This Rovsun Water Distiller is a great machine. We purchased it on sale a few weeks ago and have made several batches of distilled water. We use distilled water for our iron, CPAP, and cold mist humidifier. It's convenient to stay home and not have to go from store to store to find distilled water.

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.

I use this device for distilled water for humidifiers, so everything here is based on that use. This is a pretty good distiller for the price, but requires care and diligence. First - this device does not work well as a "set it and forget it" appliance. The auto shutoff occurs far too late and exacerbates the build up of scale - I try very hard to never let it run dry. When there is a little water remaining in the distiller, it is easy to pour out the minerals suspended in the water. If it runs dry, those minerals bake into the stainless, requiring earlier descaling. I turn it off for about a half hour (let it cool off or you can get scalded) with 10% or so left and then rinse and refill. Second - if you have hard water (as I do) descaling needs to be much more frequent than the directions recommend - I descale weekly, or immediately if I let it run dry by mistake. Descaling is very simple and I use vinegar mixed with water. That's it - and it works well. If you use a little TLC you will be satisfied. If you just want to turn it on and empty it after self-shutoff, you will likely be disappointed as some other reviewers are. But for $70 you can't expect everything. So understand what you are getting and what you will really need to do to get the best results.

Have used for 3 weeks and it works great. It is loud when using and quite a large appliance so suggest you find a room where it can be out of the way. We put it in our laundry room. The distilled water comes out crystal clear and it makes a gallon in 4 hours as promised. The crap left in the tank after is pretty nasty. Need to wait for it to cool and wipe that out. You also need to do a deep cleaning around once a month. It’s a bit or work because I make a gallon very day to feed our humidifier, but it is worth it. It should pay for itself in around 2 months.

Love it!! This machine is excellent for people with CPAP machines. We were having trouble finding distilled water for a while, so we bought this. It is so convenient —plug-and-play, super easy. I suggest you get citric acid with it, as it helps with clean up. You will need to clean it between each use. Just let it run with the citric acid in there for 20-30 minutes with the lid off, and it wipes clean as new in seconds.
