CO-Z Water Distiller, 1750W Countertop Distilled Water Machine with Glass Container Dual Temperature Display Timer, 1.1 Gallon 304 Stainless Steel Distilled Water Maker 4L for Home Office Travel

After five years of service from my 4 litre CO-Z distilled water maker, it went puff. I'd used it every day for water for our coffee machine and kettle, and saved a fortune on descaler. The increase in size to 6L is much appreciated. If you have a cold room in your house, install your CO-Z in it as it is like a little fan heater and also more effective in the cold when it comes to condensing the water. Anyway, it's free heat if you need it - and a shame to waste it. I've never used the descaler in the unit, and instead use a stainless steel scourer after every run, and it works a treat. It never ceases to amaze me how much dirt and slime and sludge it removes from our "safe drinking water" produced by that super reliable Thames Water firm. The unit is easy to use, quiet to run, cuts out when it's finished - so it's safe, plus it's pretty cheap. The water is passed through an activated charcoal filter to remove all the nasty carcenogenic organic compounds - and these are cheap to replace. The other cost saving is I no longer need the expensive Sage water filters on my Oracle Touch Coffee Machine - and all of this adds up. The unit takes about 3 hours to run, and I use this time to make bread as the spare heat is great for rising and also for boosting sour dough.

Not as noisy as some report, just like a boiling kettle, and a fan. Very effective water production, but you need to have deep pockets for the electricity used or solar. I’m guessing around 80p per litre out our electric rates, but the difference between our tap water and the distilled is worth it for me. Our TDS is just under 300. The distilled water mostly zero, or occasionally 1 or 2. I like this kit, and run at cheaper rates it is fine. Dead easy to use.

This is a brilliant distiller

I used this water distiller daily. I clean it and put it away after every use. It broke after just 2 months. It won’t even switch on. I tried changing the fuse on the plug but it didn’t make any difference (and the fuse wasn’t burned out anyway). I’m quite disgusted, especially because distillers aren’t cheap. Avoid this product!

It’s hard to necessarily get excited about a water distiller. First of all the reason I purchased this. We have VERY hard water where we live and this was destroying my coffee machine and also affecting the taste. I wanted to try making my own coffee water, starting with distilled water. So here we are. First of all, this thing is BIG! I was hoping it would fit on the counter top with the rest of the appliances like the kettle and microwave, but it’s twice the size. It’s more of a utility room type of item. It’s easy enough to use. But after one use, you see all of the deposits that were in the water in the bottom of the tank. These are actually quite difficult to remove after even one use. It does come with some chemicals to help clean this, but I think some stronger stuff I required here. I measured the PPM of the water out and it measures 0, so this works extremely well. It does make noise when in use, like a loud kettle (another reason why being placed in a utility room would be good). It takes about 3 hours to produce (I think it’s 6 litres) of distilled water. The glass jug is thin but does the job. Overall a satisfied purchase

Product is just as described. It saves us from the hard water, calcium and lime deposits. It then saves our kidneys to not make them work harder and prevents from kidney stones. It has a digital display, looks good and came in a reasonable price.

Very good

Perfect. And easy to clean.

Works as advertised. GetS 1 full gallon or water. Water here in SoCal is about 355ppm. Resulting water after distilling is ±5ppm which is fine for my purpose. If you really need 0ppm and you have hard water, you may have to run it through twice. The key to longevity on this machine is to clean it after each use. Don't wait a month or so, do it when you are done for the day. I ran it twice the other day and cleaned it with the provided "cleaning powder" and it looks like new. Maintenance is a part of life if one want to keep something always working.

I just received this CO-Z water distiller today. First impressions are listed below, in no particular order: (NOTE: I had ordered a similar distiller at half the price but got concerned when I saw that we'd entered the shipping time window and it hadn't even shipped yet, while showing "Currently Unavailable" on the product page. So I jumped on this one partly because of the "UL Listed" claim in the product description (more about that later), partly because of the high ratings, and partly because I wanted to get one of these distillers a.s.a.p. for new humidifiers that require distilled water. As it turns out that other product DID end up shipping and is scheduled to arrive tomorrow. That will give me a great opportunity to compare the two products. After that, I'll either send one back or keep both since they are getting harder and harder to find and they don't seem to be built to last.) 1. The product arrived in the original box with no second outer box. But it was intact and had all the necessary parts and was clearly brand new so no harm/no foul. 2. It was easy to put together and within an hour I had started making my first gallon of distilled water. A few caveats: A. I watched this video to show how to remove the nozzle that holds the small charcoal filter packet and it helped a lot (it's for a different brand but the process is the same): https://www.youtube.com/watch?v=1bLG8YUUlQw B. I purchased a simple 12 hour countdown timer to be able to time each distillation "run" and also to provide a sort of "on/off" switch, which this product lacks. Here's a link to that timer: https://www.amazon.com/gp/product/B00MVDTEXS/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 C. I used the hottest water I could get from my tap to fill the reservoir. 3. I did not notice any smells coming from the product, even though the instruction manual stated it was possible. 4. This product is what I would consider to be noisy, because of the fan. The best comparison I can give is that it sounds like the exhaust fan in my kitchen. I would not want to be in the same room as this distiller if I were trying to sleep. 5. It took about 20 minutes or so before I began to see the first water coming out of the nozzle. After that it trickled through at a pretty steady rate. I ran it for 3.5 hours to help make sure there was still some water in the bottom and that the minerals couldn't bake on but it left too much water, so now I'm running it for 4 hours. (It's going to be a trial and error process since you can't see into the tank to check on the remaining water level. The main problem with just letting it run until it turns itself off is that the minerals tend to really get burnt onto the bottom heating plate and I'm trying to avoid that.) 6. Even though there's no way to directly clean the 1 gallon plastic pitcher I think I prefer it to the glass pitchers given all of the negative reviews of the glass pitchers. It should be a simple matter to just put in some hot water, soap, and vinegar and swish it around to clean it adequately. And the only thing going into the pitcher is clean, distilled water. So it should be fine. 7. As stated above I bought this solely to be able to make distilled water to use in room humidifiers, so down the road I don't think I'll use the charcoal filter. I bought some evaporative humidifiers (I was tired of all the white dust from the ultrasonic humidifiers), along with this distiller, to keep the wicks from getting encrusted with straight tap water mineral deposits, hopefully extending their life. (Evaporative humidifier filters are ridiculously expensive and the product won't work without a wick/filter.) The normal TDS of my tap water is around 150. The TDS from the distilled water using this device is 0.00. That should help out. 8. I do not see a UL sticker anywhere on this product. The only thing that's visible is some CE sticker slapped on the bottom. I'm not pleased about that because it's one of the reasons I paid more for this unit vs the cheaper one(s). 9. This product does not have a handle on the top to make lifting it off easier. (The one that's arriving tomorrow, and cost half of what this cost, does.) 10. This distiller, and all the ones like it, blasts warm air into the air after it's been running for a while. This is okay in the winter; I'm not sure how okay it will be in the summer. I measured the heat coming out at 100 degrees F. (I might have to relocate it down in the basement where it's at least 10 degrees cooler in the summer.) 11. As others have pointed out the metal jug "cap" is only there to collect water. It doesn't screw on like the solid white plastic cap so you can't pour with it. I understand that they don't want to make it a screw on because you are able to turn it freely and position it wherever is most convenient. But still, how hard would it have been to make a third cap that has a spout and screws on so you can easily transfer the water to another container without having to use a funnel? 12. Obviously this is a Day One review and I can't attest to the longevity of this product. But I will provide updates over time to show how things are going down the road. For what it is, this appears to be a nice example of this kind of distiller. If I wanted something to use in a real emergency situation I would go with a stainless steel pot/copper tubing setup that can be put on a variety of heat sources and processes something along the line of a gallon/hour, vs a quart/hour. That type of distiller could also safely distill sea water. But again...for what it is...this thing seems to get the job done. (And since I don't use the humidifiers in the summer that often the excess heat might be a moot point.) UPDATE!!! Day 2 -- From first to worst!!! (I'm changing the 5 star rating to a 1 star rating.) The first batch of distilled water went fine. The second one was a disaster. There was water all over the table, soaking some tax papers I had there. It was not a leak like some people have described between the top and the bottom -- it was a leak from the "spout". Water would periodically seep over the side of the spout, rather than dripping directly into the blue container. Over the course of the 4 hour "run" it made a real mess that I didn't realize until the 4 hours had passed. It's either a design flaw or else it's defective. Either way, it made using the distiller impossible. The only thing that seemed to work was to remove the charcoal filter, which, obviously was brand new and not a matter of it being old and needing to be replaced. I was able to make some gallons without the charcoal filter but that's unacceptable for what this cost. I'm extremely disappointed with this distiller, especially for the premium price (for the lower tier of distillers) that I paid. (By contrast, the second distiller I purchased cost 1/2 of this one, but is now, unfortunately, unavailable.) (NOTE: I did receive the other, less expensive distiller -- which was a trip in itself because I ordered a Maphorn and received a Vevor, which is completely different -- and it didn't have the leaking problem of the CO-Z. AND it has a dedicated on/off switch, something the Maphorn didn't have but the Vevor did, so I was glad I got the Vevor instead, even though I don't think Amazon should have pulled a bait and switch. The only issue I have with the Vevor is that the blue container bottle stinks like petroleum distillate, even after several washings with vinegar and baking soda. I will be returning the CO-Z and keeping the Vevor.)

I've had this in use for about four years without problems. We have extremely hard water, so I splash a little vinegar in the bottom after each use and that keeps it clean quite easily. I suppose that cuts down on the cost-effectiveness, but I still like having freshly-distilled water on hand for a humidifier, C-pap, and an ice-maker. Ice from distilled water tastes terrific. The size is decent as is the water capacity. It takes about 4 hours to do a gallon. I run that much every other day. Since the time I purchased the unit, I've become far more aware of micro plastics contaminating our food and water. So, had I to do it again, I would purchase one with a glass container. That's why I gave it four stars instead of five. (I give four stars when I find something works fine but doesn't exactly wow me.) If I could give it 4.5, I would. It functions well and I've had four years of use and counting. Not bad.

So far, my device has worked fine. I knocked one star off, because I have yet to figure out how to install the charcoal filter. The manual says a filter is preinstalled so I will have to solve that in the future. I'm not sure why a charcoal filter would be needed? Distilled water should be the purist of the pure, why would I need to charcoal filter it further? The one caveat is the cleaning. After a cycle, minerals are left heat dried to the bottom and that can't be helped since its part of the process. Getting it to come off did take some effort. I started using 50% white vinegar to water and it eventually came off. I did some research on white vinegar cleaning stainless steel. Some sites say if the steel is a lower quality, the vinegar acid can pit it and it may eventually rust. The steel seems solid to me so I have been using pure white vinegar to soak for about 30 minutes and the minerals clean off easily. Then I rinse the steel liner out with water. I figure I will take my chances since it cleans so easily using this technique. Edit 5 months later: I love this little champ and use it everyday! A great tip, I just came upon, should have thought of it months ago. When a pot of water is making and if you are out of water to drink, don't turn off the machine to get some water. Its better just to pull the water bottle out, pour it into another water bottle, and place a coffee cup or some other short glass to catch the dripping water while the large water bottle is removed. Then put the bottle back under the distiller to catch the dripping water again. Just a tip to keep from turning the machine off, mid cycle. 3rd update: 6 months after purchase. I came upon a snag today and found water all over my counter while it was distilling. I notice water was coming out of the sides where the two halves connect where the seal is. At first I thought the seal went bad and I would need a new machine, but that is not the problem. Apparently after removing the charcoal filter, it runs properly and the pressure is not coming out of the sides and is going upward through the distiller. Therefore, the charcoal filter I installed must have gotten clogged and would not allow pressure upwards. Therefore, all should take care that after time the charcoal filter does not clog. I'm not going to run the machine at night while sleeping so the machine can be checked while making water. Just a warning. I still like the machine, but would give it a 4.5 stars. Another update, approximately 2 years later: The little white champ is still running great. I thought I would update since I have the lowest wattage machine, the 750 watt. It may take longer than the most powerful model, but the advantage is that many electrical outlets may not allow you to use the largest wattage model, since you will overload the circuit. This small model insures you have enough power to most outlets to power it, therefore you will not have to hire an electrician to rewire your outlet for the higher wattage for the other upgraded higher wattage model.

Living in Abq, NM our winters are very dry. Both my son and I use a humidifier in our bedrooms at night. Between the 2 of us, We go through 8-10 gallons a week -and the price of distilled at the store has gone from around .69 to almost $2 a gallon since 2020. You can do the math. I purchased ours in June 2024 and keep it in the laundry room so we can close the door -sometimes the exhaust fan noise interferes with dinner table time or watching TV. But it is not a high pitch like a hair dryer. When 1 gallon is done, I transferred it into a spare gallon containers, and we just keep rotating them so much easier to have it right in the house instead of hauling the gallons of water home from the grocery store. Appreciate the extra shielding on the 2 plugs- to keep water out. We have a half bath on the other side of the wall from the unit-so I fill the blue plastic jug with the hottest water and it only takes 3+ hours for a gallon. I was a little skeptical -the price seemed a lot at the time: $80. But over the course of two years I figure we have saved around $1000. That was estimating 5 gal a week at $1.70 gal store bought. And during the driest part of winter-probably 8-10 a week. By running it 2 to 3 times a day, it does build up some of the crud inside I do not spend money on the citric acid, though, I think it’s too expensive. I just use warm water and white vinegar one-to-one ratio and let it “cook “for about 30 minutes and then let it cool. Dump everything out of the distiller and the blue jug. Of course, make sure everything’s unplugged before you rinse it at the sink if the inside of the top where the collector system is, is getting deposits on it just use a cellular sponge with vinegar on it straightforward and just set it on there and dab it every once in a while and leave it for about an hour. So now the decision is do I keep this one and buy my son a new one for his wedding in October? Or do I give him the old one and by myself a new one? The struggle is real – ha ha ha.
