Which Is the best Humidifier for A Frog Tank

When dealing with a Frog Tank, the best humidifier is the MistKing 22251 Starter Misting System V4.0

However, this will depend on several things, like if you want it to do several tasks – like Dorm Room, or Cold and Flu symptoms.

There will also be costs for the humidifier - like Mist Type, Water Tank Capacity, Coverage Area and Noise Level. So as you can see, there is a lot in picking the right humidifier!

It is vital that the environment in a frog tank or a vivarium is maintained at an optimal level of humidity since it provides healthy conditions for their skin, eyes, respiration and even for the shedding process.

Besides hydration, proper moisture levels are essential for egg incubation and typical reptile behaviour.

How Do You Keep a Frog Tank Humidity at Optimum Levels?

Although you can use a spray bottle to increase humidity levels in a vivarium, constantly having to remember to fill a clean bottle with fresh water and mist, the inside of the terrarium can be a hassle. You could also try a programmable misting system, but most reptile and amphibian owners would recommend using a fogger, also known as a humidifier, for vivarium tank builds.

Devices such as ultrasonic foggers and humidifiers can maintain the humidity levels in your frog tank at optimal levels with less input on your part. But how do you decide what is best for your reptile or amphibian tank?

Using a cool mist or ultrasonic humidifier is ideal for pet enclosures but be sure to also use a hygrometer so you can figure out how to adjust the humidifier’s activity since different species have distinct requirements. It is not recommended to just leave the humidifier on for long periods, since in the native environment of your reptile or amphibian, humidity levels fluctuate during the day, and adjust the conditions in the tank accordingly.

How Do You Control Humidity Levels in a Vivarium?

Every reptile or amphibian specie has specific needs with humidity. If a green tree frog is comfortable with a humidity level of over 65%, snakes can manage humidity levels that range from as low as 50% to as high as 70%. If you own a gecko, it gets even trickier, since the humidity range differs depending on their species.

Besides using a cool mist or ultrasonic humidifier for your frog tank or vivarium, to get the best results you should consider other aspects that help maintain air moisture:

Use moisture-retaining substrates, adjusting them according to the needs of the species you own. You can choose from sandy substrates, coconut husk, orchid bark, or even cypress mulch. Moss is another great way to keep moisture in the vivarium, and it also enhances the overall realistic appearance of the environment.

Decrease some ventilation since it can act counterintuitively and decrease humidity levels in the tank. Always check your pet and see if there are any changes in their skin or scales' condition to see if you need to readjust humidity and ventilation settings.

Frog tanks with species that welcome more water in their environments could be enhanced with water dishes or other water setups, such as vivarium waterfalls, rain chambers and water drippers – they all increase humidity levels in a reptile or amphibian vivarium.

Hot Mist Humidifiers or Cool Mist Humidifiers for Frog Tanks?

You should choose a cool mist humidifier for your vivarium since hot mist humidifiers can increase the temperature in the tank and could harm the frogs.

Basic Features to look for in a Reptile or Amphibian Tank Humidifier

First, you need a vivarium fogger or humidifier that has a compact and durable design. Then, check for the assembly instructions, since you need it to be quick and straightforward. The water capacity is essential, so look for a larger tank capacity, especially if your tank is the home for many reptiles and amphibians.

A flexible hose will ease the installation process, while features such as dry-run protection or adjustable misting settings will ensure the safety and health of your pets. Last, but not least, look for a humidifier with a tank designed, so that is easy to refill.

This buying guide provides you with several models to consider in order to purchase the right humidifier for your tank.

Frog Tanks And Vivarium’s Hints and tips

When it comes down to it, there are a lot of different factors that go into purchasing a humidifier for your frog or vivarium tank. Some people may need a particular type and size to handle their specific needs, while others are looking for a long-term solution that will last for years of cleaning.

With that said, there are still a few things to consider when looking for the best humidifier for your space. By weighing your options, you can easily find a humidifier that works well with your current setup and will provide the humidity you need to keep your terrarium running smoothly.

1) Level Of Humidity Needed

The first thing you’ll want to do is think about how much humidity is needed in the space where you plan on setting up your frog tank or vivarium. Depending on what species of frog, reptile or amphibian you own, this can vary wildly. If you’re using a terrarium with plants, there may be a higher need for humidity than if you’re trying to keep African clawed frogs captive.

As you can imagine, terrariums are conducive to high humidity levels. If you’re looking for a humidifier that will work well with plants, then look for a unit that provides at least a pint
or two per day. This doesn't guarantee that your plant will stay alive through the harsh winter months, but it does ensure that your terrarium is kept at the proper level of moisture.

2) Size And Location Of Your Vivarium

If you’re planning on setting up a vivarium for your pet, it’s important to think about size and location. For instance, if you have a tiny 10 gallon tank in your bedroom, there’s no need for an enormous humidifier. You will be able to find a humidifier that runs on low wattage and only provides a little moisture without taking up much space.

Consider the location of your tank as well. If you tend to run out of the house for long periods of time throughout the day, then you may want to choose a unit that can automatically shut off in case something goes awry with the power supply.

3) Brand Of Humidifier

When it comes down to it, brand of humidifier matters. After all, you’re going to be relying on the product for a long time, so you’ll want to make sure you choose a company that offers an extensive warranty and good customer service.

4) Budget

Last but not least, think about your budget when choosing a humidifier for your terrarium or vivarium. There are certain models that are more expensive than others due to their features and sizes. Just keep in mind that you can find a humidifier at a reasonable price, and that doesn’t necessarily mean you have to compromise.

Just because it’s your pet doesn’t mean you have to break the bank for them. After all, frog vivariums and terrariums are decorative looks for your home and not something that need to be pricey.

5) Maintenance

There is one final thing to consider when thinking about your humidifier. Maintenance! You’ll want to make sure you can properly disinfect your humidifier as needed and replace any filters that may be affected by dust or debris. Some cleaning is required, but it shouldn’t require too much effort so long as you use the right tools.

By doing your research, you’ll be able to find the right humidifier for your frog tank or vivarium. It just takes a little time and patience, but in the end, there are plenty of humidifiers on the market that can meet your needs.

6) Humidifier Maintenance

Humidifiers require some maintenance to ensure they work properly. In addition to the regular cleaning needed each month, you’ll want to make sure you disinfect any parts of the unit that may be affected by spillage or dirt. This is a vital step in ensuring your reptile or amphibian will thrive and live happy for many years.

Depending on the type of humidifier you choose, it may need a little extra maintenance. However, there are steps you can take to help maintain your unit each year without any trouble. For example: terrarium maintenance, frog vivariums and terrariums – maintaining them along with the proper tools for cleaning.

7) Humidifier Cleaning

Cleaning your humidifier can be a simple task if you’re using the right tools. If you want to know more about the tools you’ll need, read this article with our recommendations of the most important items to have on hand when cleaning your humidifier.

8) The Impurities Of Mold

Some mold growth can be expected and should not affect the performance of your humidifier. The following natural breakdown of water: dew, spillage, etc. is less likely to create mold growth inside a terrarium or vivarium that has adequate amounts of humidity and proper ventilation.

9) Humidity Control Mistake

Excessive humidity can be just as bad for amphibians and reptiles as a lack of humidity. It could cause the temperature to rise inside the terrarium or vivarium, which could affect the delicate ecosystem of your pet’s environment. Too much moisture in an enclosure can lead to mold growth and other potentially harmful conditions that will not be good for your pet.

10) The Perfect Humidity Level

Humidity levels for each pet will vary, but most vivariums and terrarium will require a humidity level of 50-60%. It is important to keep in mind your pet’s needs for their environment. While wet conditions can be very beneficial to some species, they can be fatal to others. Water content in the enclosure should mimic the natural ecosystem of your pet as closely as possible.

11) How To Test Your Humidifier

To check if your humidifier is working properly you should first check the water level inside it’s water reservoir. If it needs to be refilled, do so and then turn on the unit again. If the humidifier continues to sputter, stops working, or fails to work at all it may be time for a full replacement.

12) In The Wild, How Do Reptiles Stay Healthy?

Most amphibians live in a humid environment, similar to those found in the rainforest. This is usually within a water-filled enclosure but it can be as simple as a terrarium or vivarium. In order for an amphibian to survive and thrive in its terrarium or vivarium, it must remain healthy and maintain a balance of nutrients, moisture and air flow. The humidity levels may differ from one situation to another but these are generally consistent which will allow your organism to thrive in its environment.


If you are anything like me, you take pride in your amphibian or reptile. You watch them play around for hours or bask in the sunlight and think to yourself “I can’t wait to see what they learn next!”. The best part of having a pet is seeing and learning about them day after day, month after month.

I have been lucky enough to have colorful and healthy reptiles as pets for over a decade now and it inspires me to continue to encourage others about the wonders they have to offer as family members.

Please Note: Just because a humidifier is marked, for example “Baby Room”, it will still work for other things, for example “Living Room” or “Plant Humidifier”
