Features
- TOP FILLING DESIGN: Easy to add water from the top, this large reservoir can hold 4.2L/1.11Gallon water. There is no need to move the reptile fogger humidifier when adding water, which can reduce the probability of water flowing back to the base and extend its service life. Top filling, plus the removable lid, make this reptile humidifier easier to clean and maintenance.
- 4.2L/1.11Gallon LARGER CAPACITY: The whole fog machine size is 7.5*7.5*11 inches, with an adjustable (1.5-6.3feet) hose and two suction cup for fixing the tube. This humidifier is recommended for terrariums of 50-100 gallons, and ideal for terrarium DIY enthusiasts.
- ADJUSTABLE MIST OUTPUT: There is a rotary button on the front of this terrarium humidifier to adjust the cold mist output. One refill can last up to 12 hours at max misting level(380ml/per hour). When water run out, the terrarium mister will shut down automatically to keep security.
- FINE MIST & SILENT RUN: Ultrasonic atomization reptile fogger humidifier, fine mist, uniform humidification without water accumulation. Low noise design (<35dB) does not disturb the rest of reptiles, especially suitable for humidification needs at night.
- 1-YEAR WARRANTY: Due to the long transportation, after receiving the parcel, please check carefully. If the reptile mister broken, do not work or any problem, please be free to contact our service email on the package, we will contact you in 24 hours.
- WARM TIP: To prevent water from flowing back to the atomizer at the base and affecting the normal operation of the reptile misting system. The connection between the cover and the mist outlet pipe is not sealed, so it is normal for mist to leak from the top when the equipment is running. NOTES: Do not move the device or add water while the humidifier is running.

This is by far the best humidifier I've ever owned. I was spending $50+ every year on humidifiers only to have them quit after 1 winter of use. This baby puts out the mist, it works flawlessly, the reservoir last a long time even on highest setting, safety features work. I have it in a 15'×22' sun room full of plants to keep moisture in the air. The plants love it, it keeps them healthy over the winter months. Would definitely recommend this product to everyone who needs a humidifier weather it be for plants or animals.

Works exactly as described. Ultra fine fog. Whisper quiet. Be sure to use distilled water so you won't get mineral buildup. Perfect for plant and animal enclosures. Setup with humidity gauge and timer so it can work without any fuss. Just refill as needed. Seems well designed and built.

I've had this humidifier for a couple of weeks now. I really want to love it, but it is finicky. We recently got a lizard that needs the humidity level to be around 30-40%. With the heat lamp & UVB lamp, the "hot" end of the enclosure was more like 10%. The "pro" humidifiers are like a couple hundred dollars and I didn't have that to spend. This one was around $50 and does the trick. Before, I was having to constantly squirt the interior with a water bottle, so this is definitely better than that, but unfortunately it's not consistent. I have the lamps and humidifier plugged into a smart power strip so that I can have them come on and off each morning and evening. At first, for like a week, it seemed to work great. I filled it, set it up, left it on minimum, and the humidity sat in the 30's. Perfect. However, when I needed to fill it up with more water, I did so and it stopped working. The troubleshooting guide hinted that maybe I put too much water in. I removed some and it started working again. How hard is it to put a fill line on the tank? I left it at minimum like I had, but the output feels more like it's up on high now. I don't get it. It was working fine. Like I said, it's better than having to spray the enclosure, but now I have to constantly check it anyways and turn it off if it gets too humid. I'm gonna try to stick with it. Hopefully, I'll figure out it's quirkiness. Pros - The 3 liter tank lasts 6 days on minimum (since minimum didn't stay minimum it's down to 3 days - still better than daily spraying, but...). / The quality of the machine seems nice. / It makes a nice fog. Cons - Finicky to set the level. / The adjustable hose it comes with gets condensation in all the little ridges and fills up with water. I replaced it with a clear 3/4" silicone tube and now I can see if there's condensation and can drain it easily. Suggestions - Replace the adjustable tube with a clear smooth one. / Put a fill line on the tank. ADD - I still wish the minimum output would be less... like it was. Currently, my fix is to leave the top lid of the enclosure cracked 1/2-1" so that some of the fog escapes completely. So far, so good.

I was a little wary about this mister because of some of the negative reviews, but I'm really glad I bought it. I don't have any issues that those reviews mentioned. The hose fits very securely in the machine for me and I have had zero issues with it. I didn't use the included clamps because others said it dented the hose, so I used a large Command hook on the wall instead (see photo), and that is working great. The machine is keeping my little buddy happy at the right humidity on nearly the lowest setting, so I know when we upsize his tank, it will still do the job. It runs silently and does not drip or leak anywhere. Very happy with this purchase.

This item is awful. It doesn’t stay on, it keeps going off. Every second I’m moving the hose around the make the green light go on and the fogger to go on. A waste of money. They need to make their products better, people spend their hard earned money on these things and I thought my iguana was going to have what she needed and now have to blow even more money on another one with this economy is already taking all of our money. I wouldn’t even leave a star if it didn’t make me. This product is awful. I’m so upset over this.

Pretty simple unscrew the clear plastic container, put 3/4 of water cap it back up and it instantly blows out the hose that points in whatever direction you aim it. I bought it for my turtle eggs that weren’t fertilized so I didn’t use it long. I think it works really good. There’s also a nob to higher or lower it. The only thing I didn’t like is how the top clear plastic container where the water goes, doesn’t clip on so if it’s knocked or hit in any way, it can come off.
