CO-Z Water Distiller, Stainless Steel Distilling Pure Water Machine for Home Countertop Table Desktop, 4L Distilled Water Making Machine, 4 Liter Water Purifier to Make Clean Water for Home

JANUARY 29, 2025 UPDATE: This distiller has now seen 29 months of constant use. During winter, it makes two full 1.6-gallon jugs of distilled water daily. In addition to my CPAP machine's humidifier, we have three ultrasonic humidifiers that we use exclusively with distilled water, so needless to say, this distiller is kept VERY busy. At this point, we've probably saved at least $2000, and quite possibly much more than that, by not having to buy jugs of distilled water. It's paid for itself many times over. OCTOBER 13, 2024 UPDATE: This distiller is still humming along, 26 months post-purchase. It runs almost daily, sometimes multiple times per day. It has saved me a tremendous amoung of money, both at the cash register - for jugs of distilled water - and by preventing mineral crusting damage on my ultrasonic humifidiers. Note that I have replaced the stock power cord with a 2-foot 14AWG power cord (NEMA 5-15P to IEC-320-C13) after observing that the original cord would get VERY warm at the ends. Since replacing the cord, the ends no longer get warm. Something to consider. ORIGINAL REVIEW: Five months in, this distiller is still working great. We use the water in both my CPAP machine and an ultrasonic humidifier, and it has no problems keeping up with the demand. Some observations and tips: I have the 1.6-gallon unit and it takes 6 hours from power on to completion when cold water is used. If I start with hot tap water, that time is reduced by about an hour. I don't usually make the full 1.6 gallons, however, since it requires allowing the unit to boil dry (I address this below). The user manual may lead some people to think that the button on the front is a START button that must be pushed to begin the distillation process, but this is not the case. That button is a RESET button, which must be pressed if the unit trips. The user manual assumes that you will allow the unit to run dry each time, thus causing the unit to overheat and trip. And because they assume that you will allow the unit to trip, they also assume that you will be starting each cycle needing to reset that tripped condition. Continuing in that vein, it is my recommendation that you do not allow the unit to run dry. Why not? Because as the water boils out, the mineral content in the boiler is getting more and more concentrated, to the point that what remains is a sort of mineral-rich slurry. This slurry will start to cement itself to the bottom of the boiler in any case, but it is a much worse problem if the unit is allowed to boil dry, making cleaning an even more unpleasant task. Rather than allowing the unit to boil dry, consider buying a digital timer (or even a smart plug), figure out how long it takes to distill 1 to 1.2 gallons, and then use that timer to stop the unit before it can boil dry. Or, if you know you will be at home when the unit has finished creating the amount of distiller water that you want, set a timer on your smart phone and then simply turn the unit off (using the rocker switch on the back of the unit) when the alarm sounds. Be careful with the AC power sockets on the rear of the unit; they are not as sturdy as you might think. There is a fair amount of flex to them and if you don't handle them gently, you might break a socket. When unplugging the cords from the unit, don't try to pull the plugs straight out. Instead, simply wiggle the plugs slightly as you gently pull, and work them free that way. Be sure not to get water in the power sockets or switches when filling the boiler. Always check to make sure that everything is dry before plugging the unit back in. When I fill the boiler, I set it in my bathtub with the reset button (front) and power sockets (rear) oriented so that they are not facing the faucet. This way, if any water splashes the electrical bits, it is minimal, and I can just wipe it away quickly with a dry cloth. The stainless steel spout on the upper housing is a bit loose-fitting (or at least it was on my unit). It is a friction fit and doesn't like to stay in place. You can position it as required, only to have it come loose just by bumping it slightly. It will also come loose if you lift the upper housing that holds the coil and fan. This happens because the tab that holds it in place merely rests on a shallow plastic ridge, and it is held there under minimal tension. The tab, when disturbed, has a tendency to bypass the plastic ridge because of the loose fit, and once that happens you have to remove the entire upper housing and reseat the spout. Very annoying. The solution to improve the fit is to bend the curved stainless steel tab on the spout slightly so that it is a wee bit straighter than its curved, from-the-factory shape. This will elongate it just enough to increase the tension and give it a tighter fit. The cleaning powder that comes with the unit is surprisingly effective. Put an inch or two of water in the unit, add a couple of tablespoons of powder to the water, and let it boil for maybe 15 to 20 minutes with the upper housing removed (and unplugged). Before the cleaning solution has a chance to boil out, power the unit off and use a wooden spoon, a heat-friendly plastic scraper, or a wok brush to further loosen the crud, taking care not to splash yourself with hot water. Then unplug the unit, rinse it out, and then repeat the process as needed. Doing this once a month or so should be sufficient. People have wondered about the tube that is included with the distiller. As far as I can tell, you would use this if you wanted to distill water into containers other than the polycarbonate jug included with the unit. The puzzling thing, though, is that unless you are distilling water into a very short container, you would probably need to elevate the distiller to have the container clear the stainless steel spout. Strange. You will likely grow annoyed with the carbon filter packets. They're fiddly and they break open, and honestly, depending on your water source, they may not even be necessary. Here's what one site has to say about them: "There are a couple of contaminants that can convert to gas with water, namely benzene and VOCs. Most distillers use a small activated carbon filter at the spout, which removes these contaminants as water drips down into the holding container." So, if you are fairly confident that your water is free of these things, and you're mostly distilling to get rid of minerals that would otherwise leave deposits on expensive equipment, you could probably forego the carbon filters. That's my situation, so I doubt I will be ordering more. Overall, I am happy with my purchase, and I feel confident that I can recommend it to others. It is a cost-effective way to not have to be dependent on supermarket stock, which I think is even more important now, given that inexpensive "store brand" distilled water isn't always an option (one national brand is selling for $3/gal).

After putting the components together, I saw the plug connected to the lid was very short so decided the longer plug was provided to allow the unit better access to a wall plug outlet. I connected the longer plug to the shorter plug on the unit and then plugged it into the wall receptacle. The fan worked, but the unit did not heat. After an hour of waiting for the unit to heat, I reviewed similar products as I planned to send this "faulty" unit back. Saw a video on another product which showed the short plug going from the unit lid to the first plug outlet on the bottom of the unit and the long plug going from the second unit outlet to a wall plug outlet. Both plug outlets on the distiller are on the back of the unit and I never looked at the back. Once I plugged the two cords in the correct plugs, the unit worked beautifully. The instruction manual did not show the back of the unit or explain where/how to plug the cords. Granted, I am mechanically challenged and feel silly for my oversight (my husband usually takes care of anything mechanical), but the instruction manual should have a diagram of the installed cords as well as detailed instructions of all steps needed to set up the unit. I purchased this distiller to avoid plastic particles leaching into water stored in plastic jugs. There is a long plastic tube included with this unit which is used to direct the distilled water into the collector bottle. I do not want the water in contact with plastic so did not use the plastic tube. The unit works well without the tubing. It drops water into the glass water collector without spillage . Another reason not to use the tube is that its length inside the collector pitcher makes positioning and removing the water collector pitcher difficult. The unit is relatively quiet. The only sound is the fan which is a soft sound. The outside of the unit becomes slightly warm, but not hot. Cleaning was easy. We have well water so the bottom of the unit was covered in white mineral deposits and there was also white debris on the underside of the removal lid. I poured enough white vinegar into the container to cover the bottom, then dipped a paper towel in the vinegar and easily wiped mineral deposits off the inner sides of the container and the lid. Waited five minutes and then wiped the bottom clean. Vinegar easily removed the mineral residue, no scrubbing needed. Did not use the cleaning powder included with the unit as I prefer using more natural cleaning products such as vinegar or baking soda. Aside from the instruction manual, this seems to be a very nice product. I put the distilled water into two glass pitchers with lids so the glass bottle collector pitcher is now available for future use. The smaller pitchers are lighter and easier to use for filling my coffee machine.

Ive been using this water distiller for a few months now. I bought because our small town has had 2 boil water alerts in a short time. It has paid for itself over & over again since Summer 2025. I'm so pleased with its size, shape & productivity.

En general una buena compra, pero el contenedor NO ES BPA FREE

Encantado con mi destiladora, increíble todo lo dañino que consumimos y que se queda en el fondo de la destiladora! Lástima que no pueda subir el video donde quedan los residuos, incluidas los de las compañías que venden agua en México! Realmente ya ni para lavar las verduras utilizo agua de la llave, uso agua destilada en su caso. En verdad no dejen pasar este producto que debe ser indispensable en todos los hogares!

Bought 2 of these at the end of March 2025 and both are already broken.

The water did taste better, but it failed after 1 year and 1 day of having, it had a melted plastic smell when it failed
