These two modes let us adjust the flow of environmental humidity, according to the plants’ needs. As such, we could get just the humidity level that we wanted at any point in time.
And the change occurred within minutes of pressing a convenient button provided on the humidifier. Thus, there were no hassles involved in operating the product as well. Also, it has a capacity of 0.06 gal which is sufficient for using it throughout an office day or an entire night while sleeping.
Plus, you can use it for moisturizing your skin or even to humidify the car while traveling. Lastly, it can deliver pretty much silent operation, thanks to its operating mode of less than 30 dB.
What Could’ve Been Better?
The only downside of purchasing this product is that the cleaning process is a bit complicated. There is an atomizer that needs to be treated once a week with acetum, then kept for some time and scrubbed with any brush afterward.
Apart from this, some other parts also require thorough cleaning. So, maintaining this humidifier will require much more effort than other products.
Pros
- Two mist flow modes for better humidification

Cons

You can also go for this advanced humidifier from Levoit which helps to create the ideal environment for the growth of all your indoor plants. What does the magic is its high-quality moisture control mechanism which helps maintain a healthy level of humidity throughout. Note that this product comes with a 1.05-gallon tank and weighs 3.5 lbs.
Why Did We Like It?
We begin by discussing the capacity of this humidifier since it seemed to be the most significant feature. It can hold 1.05 gallons of water at a time, which makes it capable of humidifying any space for as long as 40 hours.
Further, it can control moisture over a range of 24-35 sq m within any space, which makes it suitable for medium-sized plant nurseries as well. Notably, this product can also be connected to Alexa, VeSync, or Google Assistant on your smartphone, allowing you to control the humidity level more conveniently.
Also, the humidifier turns off automatically whenever the level of water is low or the tank is detached from it. This way, it becomes very safe to handle. And that’s not all; it has a silencer that keeps the sound level lowered to 25 dB and can be detached easily to clean it up.
What Could’ve Been Better?
We found that the product had to be turned upside down for refilling it and there was no handle on the bottom part. This made the refilling a bit of a hassle, which is why we felt the design of this product was not convenient enough. Also, the grab handle that is present on the upper part can be accessed only after removing the top cover.
Pros
- Large capacity lets you humidify a place for 40 hours
- Suitable for medium-sized plant nurseries
- Comes with a convenient auto turn-off feature

The best thing about this product is the convenient LED display provided it, which gives you an accurate reading of the RH at any point in time. It consists of a humidistat that is built into the machine and also allows you to adjust the humidity by three levels of mist flow.
Also, we were really impressed by the microporous cartridge which filtered all the bad odor and harmful microorganisms from the water. This way, the air consisted of fresh and healthy moisture only.
Another noteworthy feature is the set of two modes, namely the sleep mode and the nightlight mode. So, you can either turn the LED screen off or keep the nightlight on before you sleep. Lastly, the built-in handle on the water tank helps in refilling the humidifier easily and also lets you clean it conveniently.
What Could’ve Been Better?
The only drawback of this humidifier is that the tank has a small opening which makes it difficult to clean its inner surface. To deal with this problem, you can drop in small cartridge cleaning balls which help to clean up any dirt accumulating on the surface.
Pros
- LED display gives an accurate reading of RH level
- Lets you adjust humidity by three levels
- Cartridge balls filter harmful microorganisms from the water
- Allows you to sleep with the nightlight turned on

This model comes with a tank of 0.66-gallon capacity and weighs 2.35 lbs.
Why Did We Like It?
First and foremost, this product offers just the right level of humidity that any place requires. This is made possible by the 360” spray nozzle and the adjustable knob. While the nozzle helps to direct the mist flow to the areas which need moisture, the knob helps you control the flow. As such, the humidity in any room can be set at the desired level.
Moving on to its capacity, the product lets you keep your room humidified throughout the entire day. What does the trick is the capacity of 0.66 gallons can work for 24 hours, which also ensures that your plants get the ideal humidity level all through the night as well.
Finally, the automatic turn-off mechanism ensures that your humidifier shuts off safely when the water has been used up.
What Could’ve Been Better?
Although we had no complaints as such with the efficiency of the product, we hoped the refilling could be done from the top instead of the bottom. That’s because each time the humidifier was taken off the bottom base, water started dripping everywhere. Following this, the refill has to be turned upside down, which again causes water to spill out.
Pros
- Offer the right humidity level
- Adjustable knob lets you control the flow
- Keeps your room humidified throughout the day
- Shuts off safely when water is used up
Cons
- Refilling has to be done from the bottom part

Buying Guide For The Best Humidifier For Plants
Before proceeding to choose a suitable humidifier for your indoor plants, it is essential to consider your needs and preferences. The perfect humidifier will have all the features needed to provide an ideal mist flow that keeps your plants strong and healthy.
Here are the features you must look for in any product while making a suitable choice.
Humidity Settings and Output
Note that for providing the ideal air quality, a humidifier should release as much moisture as the room temperature. If it releases too less or too much moisture, that might alter the temperature.
To make this possible, high-quality products are designed with efficient controls for mist output to match the ideal air environment. Hence, it is essential to check the humidity setting and output while going through the details of any product.
Noise Level
This is an important factor to ensure that you can have a peaceful environment while getting the ideal air quality. Note that all products don’t produce the same level of noise. And especially if you spend more time near your indoor garden, it is essential to consider a product that has a low noise output. Generally, an evaporative humidifier will produce more noise compared to an ultrasonic model.
Tank Capacity
The water tank is the main source from which the humidifier generates the mist. Hence, it is also a crucial factor to consider while choosing an ideal humidifier for your plants. Note that the size of the water tank is proportional to the duration for which a humidifier can function. Hence, the larger the tank, the longer will your humidifier run without having to shut it off and refill it.
Humidifier For Plants FAQ's
Plants require a certain level of humidity in their environment to thrive. Dry air can lead to wilting, yellowing leaves, and increased susceptibility to pests. A humidifier helps to maintain optimal humidity levels, promoting healthy growth and preventing damage to plants.
A humidifier adds moisture to the air, increasing the humidity around the plants. This helps to mimic the natural environment and provides plants with the necessary moisture for proper growth and development. It also helps to prevent the soil from drying out too quickly.
While any humidifier can increase the humidity in a room, not all humidifiers are suitable for plants. Plants require a specific range of humidity, typically between 40% and 60%. It’s recommended to use a humidifier that allows you to control and adjust the humidity levels to meet the specific needs of your plants.
The ideal humidity level for most plants is around 40% to 60%. However, some plants may have specific humidity requirements, so it’s essential to research the specific needs of your plant species.
Yes, over-humidification can be detrimental to plants. Too much humidity can create an environment conducive to mold, fungus, and other plant diseases. It’s important to monitor the humidity levels and adjust the humidifier accordingly to prevent excessive moisture.
No, a humidifier cannot replace regular watering for plants. While a humidifier adds moisture to the air, plants still need water at their roots to survive. Humidifiers help to create a favorable environment, but watering the plants properly is still necessary for their overall health.
The frequency of running the humidifier depends on factors such as the type of plants, humidity requirements, and the surrounding environment. It’s generally recommended to run the humidifier during the day when plants are actively growing and transpiring. Monitor the humidity levels using a hygrometer and adjust the humidifier accordingly.
It’s best to use distilled or filtered water in humidifiers for plants to avoid mineral buildup on the leaves and soil. Tap water often contains minerals and chemicals that can leave residue and affect the overall health of the plants. Using purified water helps ensure a clean and healthy environment for your plants.
