CO-Z 1.1 Gallon Water Distiller, 4L 750W Countertop Maker, Glass Pot

This is a very sturdy and well-built machine. It is bigger than I expected but it is well worth the counterspace. (It is larger than most coffee makers.) It works very well at taking the minerals and impurities out of our water. We have 2 humidifiers and 2 c-pap machines and use 1-1.5 gallons per day, so it is used daily. The machine has run smoothly and even though it was an investment, it was well worth it because we don't have to lug heavy jugs home from the store each week. We do need to clean the machine more often than once a month as recommended, but it comes clean easily by using the included citric acid and boiling the water to clean it. I have no problem giving this 5 stars.

This is my first distilled water machine. I was amazed and disgusted at the residue that was left on the bottom of the canister from otherwise "clean" tap water. The distilled water was pure and clean. I put it in my humidifier at night. I have a Dyson air filter that "sees" the contaminants in the air. Typically, it turns to high air mode when the humidifier runs with R.O. water. Now, it runs on low to medium when it senses the added humidity. My wife and I are using distilled water for most of our personal daily water needs. We typically make two gallons a day. I'm not sure how long this machine will last, but it has been great so far. It is simple to use. The handle on the canister won't tighten completely, but it functions well enough. Also, the lid on the canister is difficult to tighten, which can result in water leakage when pouring. We use water for coffee, cooking, drinking, and other daily purposes. Taste has not been an issue with the lack of minerals.

I bought this because we have well water and it is chock full of minerals and deposits. Very hard water. Leaves residue in anything water comes in contact with. My wife would buy distilled water to cook with, make coffee and put in our humidifier, etc.. So i figured lets try saving a few bucks and get a water distiller. makes about a quart to a liter per hour. We fill ours up and run for about 3.5 hours and it gives us just shy of a gallon (because i don't let it run completely dry). Works great, auto shut off, easy to clean. So far we've made about 40-50 gallons of distilled water with it and no issues.... Highly recommend this if you are looking for something to make distilled water and not break the bank.

Only offers email customer service. No info on how to replenish necessary items. Instructions are limited but it machine works well. 1/2 of the water is wasted. Not sure where it goes. A hard to clean residue is left behind. There’s a small jar of granular cleaner to wash it with. The water barely drips into the hole if the provided glass water holder. If it gets moved the slightest the water drips on the counter.

I’ve been using this water distiller regularly and it does exactly what it promises — delivers clean, pure water every single time. The machine runs about 4 hours per cycle, which is totally expected for this process, and I appreciate knowing it’s doing a thorough job. The end result tastes noticeably fresher than tap or even most bottled water, and I love the peace of mind it brings. The build feels sturdy, it’s simple to set up, and cleanup is straightforward once you get into the rhythm. For the price, it’s an excellent way to ensure you always have distilled water on hand for drinking, cooking, or even mixing with baby formula and herbal remedies. The only drawback for me is the pouring function — it can feel a little clumsy when transferring water to smaller containers. Because of that, I’d give it 4 stars instead of 5. That said, the performance and value are solid, and I’d still recommend it to anyone who cares about the quality of their water. Homestead mama certified 💯 🌱

Yes! Both my husband and I use a cpap machine. This pays for itself in no time! We have distilled water without constantly purchasing at the store all the time.

DO NOT PURCHASE THIS WATER DISTILLER! We bought this model only 6 MONTHS AGO and it is now DEAD! Worst design ever. There was a loud explosion in the kitchen a couple of weeks ago while the machine was running. After the explosion, the distiller was dead. The plastic button assembly on the front is what gave out. When we picked it up, the button assembly was rattling around inside of the machine. No way at all to fix it. This is the second distiller we have had in the last 2 years. This style of distiller has the plastic button on the front which is the weak point on every machine. The machine gets too hot to have plastic parts on it. This machine is a rip off. All of these machines are made in China and it shows. Our next distiller will be made in the USA.

I had the same brand , but my grandmother wanted to buy one, so I gifted her my previous one n bough this one for me, I like that it has a timer n it turns off by itself. The only thing I find weird is that there is no cap handler , to like lift the top off, the other one does have that.

The best water distiller I’ve tried!! It’s quite a fast process, easy to clean and looks nice. Right from the first distilling process the water was great.. no smell just clean water! I always reactivate the distilled water with minerals and I couldn’t be happy with the water I’m drinking now. My only niggle is the handle on the water jug isn’t completely fixed and I found it annoying, so I put a strip of silicon under it and that worked! As well as that, the jug does drip a little when transferring the distilled water to my water jug for use. But these are fairly minor compared to what is a fantastic distiller. I’ve tried a couple of other distillers before and this is by far the best and at a good price! Highly recommend!!

J'ai utilisé ce distillateur tout l'hiver pour fournir mes deux humidificateurs. Il fonctionne très bien. Il est bien conçu et fiable. Je l'utilise dans une chambre à part car il degage un peu de bruit et de chaleur mais pas au point d'être dérangeant.

I use 2 humidifiers & have several house plants. I bought this water distiller in November 2025 and I’m glad I did! Before using distilled water, a fine white dust landed on my furniture from using hard water in the humidifiers. But this year, none of that mess! My house plants are healthier with the distilled water. I also am relieved to not have dozens of distilled water bottles to recycle. Given the cost of a 4 L jug of distilled water in my neighborhood, I will save money as the seasons continue. This machine is a great workhorse! Often during the winter, I ran it constantly, including overnight. Once I used what came with the product, I bought more “food grade” citric acid powder on-line, even though I don’t drink the water. It boils off the hard water scaling perfectly. Depending on how often I use the machine, I de-scale it every 2 weeks or less. Unlike other reviewers, I don’t find that the machine makes the room too warm while it’s running. But, I keep my temperature lower than some to save on heating bills in the winter. Hopefully this machine will continue to do what it’s supposed to do for a few years, so that it is truly worth my investment.

I absolutely love this distiller ! I don’t know what we would do without it. Crystal clear water I cook with it use it for everything. So much cleaner and gets rid of all the nadties in our tap water , don’t drink that horrible tap water Anymore. I’m impressed with the quality and easy set up and instructions. Can’t fault it plus it’s great in winter for warming my kitchen up! Everyone should have one. You’ll be amazed at what it takes out of the tap water . Taste pure and clean

Excellent product made of great materials 👌 Stainless steel and glass are the best for every type of water purification systems. I’m very pleased with this distiller’s performance. It’s very quiet, very reliable giving excellent TDS purification score 000 I’m also very pleased with customer service responses, when I needed 👌 Thank you ☀️
