Vevor Pure Water Distiller 750W, Purifier Filter Fully Upgraded with Handle 1.1 Gal /4L, BPA Free Container, Perfect for Home Use, White

I've been using this Vevor (aka Mophorn) pure water distiller for 10 months, running it at least once a day and often two or more times a day, 7 days a week. It's performed well and continues to provide a good quality distilled water (see below) with regular maintenance.Suggestions (lessons learned)1) Do not run it dry. i.e. Do not let it run until the automatic shutoff turns it off. It takes roughly 4 hours to distill about 1 gal. of water. So, I have the unit on one of those inexpensive wall outlet timers set to shut it off after about 3 1/2 hours. This way the 'minerals & impurities' do not get "burnt on" the bottom so it's easier to clean and doesn't 'pit' the stainless steel. Personally, I disconnect the power cord from the wall timer to the unit as soon as I notice it has shut off. [Suggest you experiment with the 'time' if you have "Hard" water. You may want to shorten the time to 3 hours, producing less distilled water but 'saving' the units bottom from being as built up.]2) After the distiller has cooled for at least 30 to 45 minutes, disconnect the plug from the upper to the lower unit, take off the condensing unit (top) with care as hot steam may still come out and hot water clinging to the unit will 'spill off' as soon as you tilt it. Set the top it aside and pour the leftover water from the distilling unit (bottom). Carefully because it will still be hot, wipe out both top and bottom with a soft cloth or paper towel. Take care when wiping off the upper unit being careful around the vent cover that the water vapor goes through to the condensing coil. Be sure to gently wipe off the soft seal on the top unit to keep it clean. Set both parts (top & bottom) on a towel or over the edge of a sink to dry being careful not to ding or damage the edges. Part of the reason for allowing the units (top & bottom) to dry at this point is to let them cool. If you are in a hurry to produce another 'batch' of distilled water, I suggest you let the unit cool for at least 15 to 20 minutes before proceeding.3) Mix a couple ounces of vinegar with a little water and using a soft cloth or paper towel, wipe off the inside of the upper and lower unit with the vinegar & water mixture. Pour the remaining mixture out and rinse with tap water then wipe the inside with a damp soft cloth or paper towel. I usually lightly rinse it again just to be safe but that's "Belt & Suspenders" thinking. Set the units aside to dry or fill to run another batch.While I agree that this is not a 'laboratory Grade' distilling device but consider it a good quality 'Home Use' distiller which should produce reduced levels of 'harmful' contaminants from tap water when properly used.Even though the unit is as loud as an evaporative humidifier when operating, I find this Vevor Tabletop Water Distiller well this worth the money, but it does require care to maintain it so it will last. My most important piece of advice is do not let it run 'dry' and clean it with a vinegar or ascorbic acid and water mix at a minimum of every other use.AddendumI noticed a few negative reviews questioning the quality of the 'distilled water' produced by this unit, so I thought I'd add some thoughts and observations for those interested. There are many considerations that impact "what kind/level of distilled water" you need for your proposed use.First, there are different levels ('kinds') of "Distilled" water. No simple, single stage, countertop distilling unit will produce 'Technical or Laboratory Grade' distilled water, especially at this price. Filtering or distilling water for 'Human Consumption' is quite different than filtering water to produce water for a marine reef aquarium or use in a laboratory. Water processed in typical water plants for 'Human Consumption', often has certain chemicals added intentionally and/or inadvertently which are considered beneficial to humans. Chemicals such as Calcium, Potassium, Molybdenum and Magnesium are required by humans to stay healthy. In many areas Fluoride is added to "promote stronger teeth" and reduce tooth decay.While small levels of lead and copper are considered safe for human consumption, even a small amount of copper in marine reef water can poison and kill a marine invertebrate ('coral') and small levels of either are usually considered unacceptable for most laboratory grade distilled water applications. [FWIW, most Technical Grade and especially ASTM Deionized water is harmful to drink or even get in your eyes.]So, if you're primary purpose is to produce drinking water or water for home humidifier, when properly used and maintained, this unit will provide a highly reduced level of a large majority of 'unhealthy contaminants' found in most USA produced 'tap water'.Personally, I produce two levels of filtered/distilled water for our home use. First, for our humidifiers, I filter our tap water through two different gravity fed filters that contain 'mixed bed ion' with activated charcoal filtration. (see attached photo) This lowers the percentage of mineral impurities and unnecessary chemicals not needed for use in a humidifier. Reduces the 'white dust', etc. you may see from using unfiltered water in a humidifier. Second, I also use the double filtered water in this distiller to produce water to add moisture to the output of an Oxygen Concentrate and CPAP. This distillation greatly reduces many secondary 'pollutants' not desired for inhalation such as chloride, sodium, nitrates and sulfates as well as helping to ensure that any microbial, fungi or viral microorganisms possibly present are killed. While some of these can be safely ingested, they can be hazardous when inhaled especially by someone with 'lung issues'. [For the 'purists', I also gravity drip, reverse flow feed the output of this distillation unit through a water quality ultraviolet (UV) sterilizer into a Nalgene container using medical grade tubing providing approximately 15 minutes UV Light contact time.]In reviews comparing results of before and after impurity levels from a Certified Laboratory, I would suggest:1) A Certified Laboratory Test should also be performed on the store purchased 'distilled water' you're buying for a "fair" comparison to the performance of any distillation unit you are using. You may be surprised at the test results for distilled water you purchased at your local grocery store for a few dollars. You may also want to do a comparison with 'Nursery Water'. PS, be sure to include a 'Fluoride Level' test in Certified Laboratory results.2) In looking at the water quality, before and after test results posted in some reviews, I theorize the 'after distilling' with a unit like this was possibly A) Not run as suggested 4 or 5 time (with the water produced discarded) prior to sending the produced distillate to a Certified Laboratory for testing. And very likely B) The unit tested had the "tea bag' style activated charcoal filter installed. Probably, the 'Activated Charcoal' filter had not been pre-rinsed and 'washed' properly prior to use.For many years I was a Certified Water Plant Operator and have maintained marine reefs aquariums for decades which require stringent water parameters for the health of the invertebrates. So, I ran the following tests this weekend after probably 400+ uses of this unit. I don't have the test kit/equipment to run several other tests often run for drinking water such as the various polyethylenes, vinyl chlorides, cryptosporidium, Haloacetic acids, Barium, Beryllium, Cadmium, etc.These results are the findings for my water supply.

The name on the Distiller that arrived was NOT Mophorn, but VEVOR. I have had this Distiller now for 6 months and it is working well. I have made many gallons of good tasting, quality water With no mechanical issues at all. The secondary filter fits into the spout that disassembles and the fan is nice and quiet unlike complaints of loud fans by other users of the Mophorn labeled distiller. The MFR must have improved on the fan's quietness. I have more than broken even by saving money on water I formerly bought in the store. IMPORTANT! I use a timer set for 3 hours to both protect machine from overheating and makes it easier to clean after each gallon is distilled. The little extra water left behind is really insignificant and protects machine from having to raise the temperature in order to trigger the auto shutoff feature and also making sure the residue left behind doesn't bake into the metal this makes it harder to clean and could decrease the life of the machine. The timer I use is found here on Amazon:Link > https://www.amazon.com/dp/B00MVDTEXS?ref=ppx_yo2ov_dt_b_product_details&th=1This Timer is inexpensive, easy to use and works great. This is the second review.. I have more than broken even with the cost of Machine vs buying distilled water at the store. and have actually made a profit of $80.00 and the machine is still putting out water. Since I have been so happy. I have taken that $80 I made and purchased another one, putting it aside in case this one does fail. So far so good though. The only potential problem I can see is the seal where the top meets the base. This seal is important in keeping the steam contained while its distilling. The only wear I can see happening is from the habit I have of after placing the top onto the base and after doing that twisting the top around while on the base to align it. Just place the top down on the base and do the positioning prior to placing on the base and don't twist or rotate the top around and it should make the rubber seal last longer.3rd Review GOOD NEWS. I bought this unit in March of 2023 it is now January 3rd 2024. This machine is still running strong after 8 months. The money it saved me (8 Mos @ $30.00 Per month = $240) paid for this unit. It saved me almost 3 and a half times what it cost. I owe it lasting this long, to using the timer to shut it off after 3 hours. If you buy this machine you MUST buy a timer before using it. I have read horror stories of those who did not use the outside timer. Do yourself a favor and get one for this unit especially. The timer sited above has worked very well.

I bought this because I was tired of paying for distilled water for my humidifier and the Zero water filters were costing a fortune. It works great, takes my 450+TDS tap water down to 1. Takes about 3 hours to do a gallon. I work from home so I just let it run in the kitchen during the work day. It is about as loud as a bathroom fan. Super easy to clean. After I've made a couple sometimes three gallons of water I take off the top and wipe it down, put about a 1/2 to 3/4 cup water in the unit, sprinkle in a table spoon or so of citric acid and turn it on (no lid) for about 30 seconds or so, swish the water around a bit and you will see the build up on the bottom of the container go away. Pour it out, give a good rinse, wipe down the sides and dry it off, put the top piece back on and ready to go. I'm averaging about 5 gallons a week so it won't take long to pay for itself at that rate. Fits on the counter top.
