CO-Z 4L Pure Water Distiller

This is the second CO-Z 1.1 Gallon Water Distiller we have purchased. We are not as happy with this newer model as the last because they changed the design a bit and I don't believe they improved it. The designer removed the straw that previously was attached to the lid which work worked well. The new design made us uncomfortable that the distilled water would actually drip into the receptacle so we attached the straw from the older model and attached it to the new. The new design also removed the only place to hold onto to remove the lid once the water was distilled. It is very awkward to remove the lid now. They should not have "fixed" that which was not broken.

Easy to use and install. Don’t mind how long it takes to fully distill the water (about 4 hours). Surprised how dirty it can be after the distilling process and it’s not too hard to clean. We don’t drink the distilled water, we mainly use it for our humidifier and steam cleaner.

7 months in and its still supplying the water I need for the CPAP and other distilled water needs. I read a review where it said it stank and left stains. That would be due to letting the machine run thru its full cycle. The stain and odor would be from the minerals and other junk in the water that is left behind. I add a small splash of vinegar to the water and shut it off before it fills the jug. No odor while in operation.

Have been making a gallon or two a day for a week now. It’s easy to use. I can hear a humming sound from the fan and it takes about 4 hours to make a gallon, but neither bother me. The local store here charges $3 / gallon for distilled water so it will pay for itself quickly.

This machine is tiny but mighty. As opposed to larger $300-$400 reverse osmosis systems I looked at. Reverse osmosis is very pure distilled water, you must mineralize it with salt with low iodine percentage, high mineral and magnesium content. This distiller machine is expensive but also budget friendly. This water is good for household appliances, not for drinking unless you remineralize it. You can smell the purity of the water after the first mandatory runs using the machine. Running the machine at least once is required before using the water. You can discard it into your plants. Distilled water is for used for steam irons, humidifiers and CPAP machines for sleep apnea. It doesn’t make that much noise but in the video you can hear it is loud when you’re near it. It sounds like a box fan or my air purifier on full blast lol. I only have it 4 stars because my parents said it’s a waste of money as opposed to buying from the store and wasting electricity. Also you have to check the machine from time to time. It does get warm after 30 minutes when it starts to produce water. It is also pretty fun to watch. I’ve only had it for about 3-5 days but I think it’s good if you’re using it for yourself. I didn’t want to buy distilled water at the store. Making trips to stock up for the week along with plastic waste was not something I wanted to deal with. It can range from $2-$4 per gallon. Plus I need it for my 6.5L humidifier I bought to add moisture to my room because my dry skin. I have not had it long enough to talk about longevity and durability. However for the price I think it will last you 4-5 years with proper care. The quality is good. The instructions are easy to follow and the instructions match the timeframe when the water is about to start warming up and dispensing pure distilled water. After 30 minutes of the machine being turning on it starts the water production. 4.5-5 hours is when you get your gallon of hot water. Leave the machine alone to cool after you turn it off and unplug it, about 15-20 minutes. The steam will be hot but if you leave it alone to cool you won’t risk any injuries. The provided cleaner makes it easy to clean the machine as well. I would purchase again if I lived by myself for my appliances.
