VEVOR Water Distiller, 4L 1.05 Gallon Pure Water Purifier Filter for Home Countertop, 750W Distilled Water Maker, Stainless Steel Interior Distiller Water Making Machine to Make Clean Water, Silvery

1. DO NOT run these things until they're empty. The "breaker" on the front isn't the greatest, but nice to have if you get distracted once in a blue moon.2. I have Alexa set to turn this off after 3 Hours 45 Minutes - perfect every time with ~3/4" water remaining; you can just set an alarm otherwise or a wall timer... just try to keep it under 4 hours. Be sure the TIMER is rated 15 Amps.3. Do not allow the two electrical plugs in back to get wet AND plug them into the unit - they will corrode if they're making contact. Allow everything to dry completely before plugging them back into the main unit. If they get wet - dry thoroughly first.For cleaning:---------------Each time the machine is used, minerals will get baked onto the stainless of the main unit. DO NOT try and scrub this off, you'll be wasting your time and possibly eroding the thin stainless shell. Instead, use the enclosed Citric Acid (Which you can buy a much larger jar at WalMart for ~$7 or here for $20 per 5lb bag!)How/When:---------------With a clean device, run a full gallon of water - empty the jug into what ever storage you've planned. Leave 1/2" to 3/4" of water! Approx 3 1/2 hours or so. Rinse the unit and refill when it cools a bit. Never put COLD water into a HOT ANYTHING. It never ends well.Run a second gallon (there will be a little residue stuck from the first one. It has no effect on the process or the water distilled.) With the remaining 3/4" of water, sprinkle in about 1/2 TSP of Citric Acid (included with the purchase) and run it for half an hour WITH the water jug set up. Once water begins to come out of the unit and into the jug it's okay to shut it off. Clean out the unit with a little dish soap and rinse thoroughly. Soap and/or Citric will leave a taste -- make sure it's rinsed well! You will want to take the top half, "fill" it with water from the sink, allow some to fill the condenser coil and then turn it over and empty it into the sink - water will come out of the nozzle. I usually rinse this a couple times any time I use Citric to avoid potential "taste" of the citric acid from getting into the distilled water. (Imagine the "taste" of concentrated lemon peel... that's basically how citric acid is made if it's not man-made.)Run another two gallons like before, but this time, for cleaning, fill the unit to the water line and then add the Citric. The Citric water will only "clean" what it can touch - so now we're cleaning it to the water line. Again, once water begins to come out of the unit it's okay to shut it off - I have Alexa doing cleanings for 30 minutes which works splendidly.(You can do 2 gallons and then a complete cleaning every time - it uses and wastes more water this way, thus the directions above, but if you want "clean, clean" it shouldn't hurt the machine any.)* NOTE: This hot, citric acid water is like bleach for cleaning - without the bleach! If you have hard-water which stains your sinks/toilets/etc. slowly/safely pour the used Citric Water into the toilet and allow it to soak for a while -- it can visibly help! If you allow it to cool a little, clean your stainless appliances with it!* Citric Acid is potentially corrosive. Avoid getting it in the AC outlets of the machine as it can pit the copper.* Water in general is dangerous when dealing with electricity. For more thorough safety, be sure to unplug the unit from the wall before doing ANY of the above. (or use a smart outlet which in effect does the same thing.)* The unit itself is leak-proof if setup and maintained properly. There is a large rubber "seal" on the top half which you will want to wipe down when cleaning the machine and look for defects/tears. When putting the top onto the unit - do so with a GENTLE force. The WEIGHT of the top is usually enough force. If this seal gets damaged, leaking is easily expected when the "full tank" comes to a boil.* DO NOT leave Citric water in the tank for ANY extended period of time. Once it has done its job, let it cool a little and dispose of it. It may not have an "eroding" effect on Stainless, but my thoughts are "why take the chance?" Some of the reviews showing "burn holes" in Stainless make me assume large quantities of Citric being left for long periods of time or the machine being allowed to run EMPTY making the metal become brittle over time - but that's just an educated guess. (Trust me, I'm an engineer! :) No really, I am!)* Finally, you'll want to replace the carbon filter around every 20-30 gallons or so (you'll likely "taste" when it's time to do so) There's filters on amazon that claim $10 for 100 (1.5") and $18 for 48 (3") which should work with this unit (the 1.5" ones will probably last "half" as long, but should "fit" nicer in the distiller.)WARNING: If you CRAM the filter into the nozzle too tightly, I'd imagine the unit WILL leak as the water will not be able to get through the filter fast enough and thus overflow the same way a coffee maker will. There's plenty of space inside - no need to conserve!Finally, if you're weary, place the Unit as well as the Jug on a cookie sheet. (I've left my jug on it there as there's always going to be chance for minor spills, condensation or what-not.) It won't hold an entire gallon, but if the unit has been running 30+ minutes and you come back to check on it --- if there IS a problem, you'll SEE it and be able to stop it *before* creating a mess.I believe I've covered most of the common gripes and potential problems I read here before purchasing my first unit. We go through numerous gallons of water daily (multiple humidifiers, CPAP, etc.) and though I've only had my unit a bit over a month, it'll be close to paying for itself by the end of month #2 which is when I'll be buying a second one.You may also want to consider the extended warranty. For the cost of the unit and the warranty amount, it doesn't take very long for them to "earn their keep." A bottle of Wally-World brand Distilled runs about $1.60/gal here. That's up to $6.40/day in my household during the winter season. That's a LOT of plastic jugs heading off to the landfill I didn't want to sponsor. I'm only running the machine while I'm home (due to the negative reviews - tainted trust? though it's easing over time) so I'm down to $3.20/day store-bought and the remainder from this unit and weaning little by little. Even if the unit only lasted a year and even if I didn't have the extended warranty, that's EASILY 100 plastic jugs I didn't bury and $160 I didn't spend on doing so... minus the cost of the unit... you see the savings!"Oh, why don't you recycle the plastic jugs?" As noted... I'm an engineer. I know things... and people.At least here in NE Ohio, a good chunk of "recycle" trucks take your extra efforts from you and you feel good about yourself trying to "save the planet" and they head straight to the landfill. You PAID EXTRA to be able to recycle (in most cases.) Our landfill is only 7 minutes away from my house and I go there for manual deposits when I need to. I have personally watched recycle trucks enter the dump site. There's no sort building at our landfill... where' did everyone THINK it would go!? :) "Beam me up, Scotty??"

Almost a year later and this water distiller is still working reliably.I first bought this to distill water for a humidifier and for some plants that require distilled water (calatheas). Over the dry days of summer I could use this once a day, sometimes twice a day when I need to water my plants. It hasn’t failed me yet, and it works pretty much flawlessly.With such regular use it can accumulate calcium on the bottom really quickly. Luckily, it’s super easy to clean by just distilling water normally and putting in a little citric acid to dissolve the calcium buildup and cleaning away the resulting sludge.My only complaint is that the top of the lid can accumulate condensation that drips all over when removing the lid to fill the reservoir. Not a big deal, it’s an easy cleanup, but it’s mildly annoying. One other small thing is that I can be a tiny bit loud when operating.If any issues come up I’ll update this review. But for now, nearly a year later and heavy use, I couldn’t be more satisfied with this distiller.

I bought this as a replacement to getting jugs of distilled water. The machine itself is nice, but it doesn't do the job it's intended for. At all. The first time I ran it I cleaned it like the instructions said, it leaked that time. All over my counter. The second time I ran it I thought maybe the nozzle wasn't adjusted properly. So, I adjusted the nozzle and the filter. I ran it the second time, once again it leaked all over my counter and didn't produce any distilled water at all. The third time I ran it, I checked the seals. I checked the nozzle. I went to run it again, and once again it leaked everywhere and produced absolutely zero distilled water. The fourth time I ran it, I wanted to be very sure that I'm using the product as intended. I read all of the instructions, checked all the things it told me to. Did all of the troubleshooting, checked all the seals and all the areas it could leak. After running it the fourth time, having it once again leak absolutely all over my counter. And produce absolutely NO distilled water into the provided jug I desired to return this malfunctioning contraption. It took me a few days to pack it up, and in that time I ran it a fifth time. Just to be sure. The fifth time I ran at the same thing happened. It leaked everywhere on my counter, it filled the jug with no distilled water. And essentially was useless.I've never been more disappointed in a product in my entire life.
