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.
Customers say
Customers find the humidifier effective at maintaining humidity levels, particularly for reptiles requiring high humidity, and appreciate its quiet operation. The product receives positive feedback for its quality, with one customer noting it’s better than the repti fogger. However, the functionality and fog production show mixed results – while some say it works well and produces fog nicely, others report it simply stops working or doesn’t produce any mist at all. Moreover, customers report significant leakage issues, with massive drips coming out of the hose every couple of minutes, and mixed opinions about value for money, with some saying it’s expensive but works well while others find it not worth the cost. The longevity is also mixed, with some reporting it lasts up to 2 days on low setting while others say it completely dies within 3 months.

Great Product
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’Ã22′ 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.

Great little mister for our ball python!
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.

Works great for a budget humidifier, but I wish the minimum setting was less.
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.

Doesnât work
This item is awful. It doesnât stay on, it keeps going off. Every second Iâm 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 wouldnât even leave a star if it didnât make me. This product is awful. Iâm so upset over this.

it does the job fast
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 werenât fertilized so I didnât use it long. I think it works really good. Thereâs also a nob to higher or lower it.The only thing I didnât like is how the top clear plastic container where the water goes, doesnât clip on so if itâs knocked or hit in any way, it can come off.

Fogs great, so quiet! LOVE the top water loading so I donât have to take the whole thing apart
I love this fogger I had the 1 gallon coospider before I bought this 4.2L coospider and I LOVE loading water from the top and love just how quiet and how good this machine really is!!

Leaks mist from top, and output was less than expected but well built unit
I’m using this for humidifying a curing chamber. The problem I experienced was almost half of the mist was coming out of the top of the unit and not going through the hose. This was before connecting the hose to the chamber so I’m sure it would not get better after it would be connected. It appears the lid does not seal well to the tube coming up from the ultrasonic humidifier plate allowing the vapor to escape from the holes in the lid and not flow well through the hose.Other than that, the unit worked well. I thought the amount of cool mist being produced was not what I expected when the unit was set to the highest level but it was working. I liked the top fill design and would have worked well for my application had the mist been contained. It may be a little difficult to see in the photos but if you look close you will see the vapor around the top of the unit. Disappointed it was not good for my use but otherwise the unit was built well, holds a lot of water (more time between fillings) and did not leak at all.

Works really well keeping the humidity up in my terrarium. Still needs to be sprayed a bit throughout the day but this helps a lot.The only downside is that if you have a mesh lid on your cage, the fog will seep out and the machine will need to be run all day, and it won’t get as foggy as it shows in the pictures. The only thing that would fix this is if the fog machine had a higher fog output setting, but then you’d probably go through too much water. A full tank will last more than a full day which is super economical if you’re buying distilled water.The hose also does spit some water out every once in a while, so just make sure to set it up over something that can get wet.Overall really good product, does what it is meant to do and makes a big difference in humidity.

I bought other fogger for my Chaneleon but it didnât work. I read many reptile and amphibian owners had huge problems with foggers from big known brands. So i was in bad situation as the need for fogger was big. Then one person recommended this product and i bought it. I ve been very happy with this product. I definitely recommend to everyone ðð»

El producto tiene buena apariencia y funciona bien, sin embargo, me parece un poco elevado el costo para lo delicado que es en material y cuidados que se le debe brindar. También, hace falta que tuviese un seguro para sujetar el recipiente a la base ya que sólo se coloca uno sobre el otro.

Ordered this for my hermit crab terrarium. Have had it for a week now and works amazing. Hopefully it stays that way. Basically keeps constant humidity/mist in my tank which alleviates a lot of manual spraying. I use only distilled water which hopefully prolongs the use of the machine and prevents issues long term. I love that I can choose the amount of mist that it creates. Fairly quiet machine, runs for a long time without having to refill it. Maybe the hose coming from the top could be a bit longer but it works fine for me.
