Best Humidifier for Plants: A Review

1. Geniani Erie 250ml Portable Cool Mist Humidifer

The Geniani Erie is a travel-sized cool mist humidifier.

It is only six inches tall, weighs 0.55 pounds when empty, and its diameter measures a mere 3.43 inches.

This device looks like a standard-sized tumbler and fits almost all vehicle cup holders.

It comes with ten replacement cotton filter sticks and can run for up to eight hours on a single full tank refill.

The removable tank has a capacity of 250 milliliters, which is enough to humidify a footprint of 65 square feet.

The Erie draws power through a single micro-USB port on its rear.

It can also run on electricity from a car battery, a power bank, or a wall outlet.

This humidifier is available in black or white.

If you need something with a higher capacity from the same brand, you should check out the Geniani Huron.

Unlike the Erie, the Huron can hold up to four liters of water.


The Geniani Erie may be compact, but it is a powerful humidifier.

It offers the perfect balance between portability and performance, making it an excellent choice for almost any environment.

This device is a high-quality humidifier for the bedroom, the office, a baby room, a car, or even a plant nursery.

It is an ultrasonic cool mist humidifier that can instantly boost comfort levels using two mist modes.

At only 38 decibels during operation, the unit does not produce much noise.

Cool mist modes include a continuous mode and an intermittent misting mode.

Whichever option you use, the Erie can change the ambient humidity in a matter of minutes.

Geniani simplifies the operation of this device to just one control button; it does not have any complicated and unnecessary features.

In addition, the device has an auto shut-off feature that kicks in as soon as the tank does not have any water remaining.

Since you’re looking for a humidifier for your plants, you’ll be happy to know that the Geniani Erie gets the job done.

Plants that need a specific humidity level can get their share of free-floating water with just the Erie misting nearby.

However, since it can only run for eight hours and mist a limited area, it can be inadequate for some setups.

In that case, you might want to consider getting a higher-capacity humidifier.


  • Lightweight and portable
  • Most affordable among the choices
  • Silent operation
  • Has a night-light feature
  • Modern, sleek design
  • Easy maintenance


  • Capacity may not be enough for some
  • No remote control features
  • No tray for essential oils

2. TADLIATIV 6L Ultrasonic Smart Control Cool Mist Humidifier

The TADLIATIV Ultrasonic Cool Mist Humidifier is a higher-capacity unit with smart control features.

Measuring 14.0 by 9.0 by 9.0 inches, it can hold six liters of water but can operate with just one liter in its tank.

Since it weighs 4.24 pounds, it is not as portable as the Ganiani Erie.

With the tank at full capacity, the device has a runtime of 50 hours and a coverage of 500 square feet.

The TADLIATIV has a top-fill design, which means you can easily refill the tank with water even while the device is in operation.

It has front calibrations that let you know how much water is left in the tank.

Aside from turning water into mist, it also has an aromatherapy feature.

It has an aroma box that allows you to add your favorite essential oils and give the mist a natural, calming scent.

Moreover, the unit has a 360-degree rotatable nozzle, enabling you to alter the mist flow direction as desired.

While the device can automatically set the constant humidity output, you can choose from three humidification levels: low, medium, and high.

The device has a built-in thermostat and humidistat to allow precision with the automatic setting.

You can change the settings using an LED control panel, and the device automatically turns off as soon as the tank runs out of water.

Other features include an operational timer and a display shut-off switch.


If you are looking for something that doesn’t have to be portable, this six-liter Humidifier from TADLIATIV is the most versatile unit you can get.

Overall, this device works great for plants as much as for humans.

It can be a helpful tool in the bedroom, living room, nursery, or indoor garden.

Unlike the Geniani Erie, it can run for a little more than two days straight on a single full tank.

Additionally, it provides convenience with its directional operation, especially for indoor gardens where a group of plants needs more humidity.

The smart control timer and humidity functions are also good additions to its features.

You can set the device to stop running for as short as an hour or as long as 12 hours.

Moreover, you can use the device’s humidistat to check a room’s ambient humidity.

You can also set a room humidity level that the device should maintain.

Once the humidity within the space reaches the preset conditions, the device will automatically shut down.

We also like that the TADLIATIV is a low-noise humidifier; it only produces minimal sound measuring up to 36 decibels.

The only disadvantages of this unit are its extra-bulky design and its lack of remote control functionality.


  • Multiple smart control settings
  • Lots of features for its price
  • Omni-directional humidification
  • Built-in humidistat and thermometer
  • Water-fillable while in operation


  • One of the more expensive options
  • Might be too bulky for some
  • Largest humidifier among the choices

3. Levoit Classic 300S 6L Ultrasonic Smart Humidifier

The Levoit Classic 300S is another six-liter capacity ultrasonic smart humidifier.

It measures 9.6 by 7.5 by 13.4 inches, weighs 4.3 pounds, and is available with transparent blue or gray tanks.

This six-liter humidifier can provide up to 60 hours of continuous mist on the lowest setting.

However, you can also amp it up to medium, high, and auto modes.

The Classic 300S can humidify an area measuring 215 to 505 square feet on a single refill.

It also automatically adjusts mist level settings in auto mode to maintain relative humidity between 40 and 50 percent.

You can also set a customized target humidity level that the device needs to maintain.

Like the TADLIATIV, the Classic 300S offers features for aromatherapy.

It has an aroma pad where you can add a few drops of essential oils to produce a fragrant mist.

Extra features include an optional night light, a top fill design, and a low noise level of 30 decibels maximum.


While the Levoit Classic 300S is at the same price tier as the TADLIATIV, it has far better smart control features.

Since it is a WiFi-ready device, you can use a smartphone to give it instructions over your home network.

It can also respond to voice prompts through the VeSync app, and you can use third-party voice assistants, such as Alexa and Hey Google.

With the VeSync app, this unit allows you to adjust settings and create unique misting schedules right in the palm of your hand.

A significant advantage of this design is the capability of operating the unit even when you are nowhere nearby.

As long as you leave the unit plugged in and with a tank full of water, you can send it instructions from anywhere, anytime.

If some of your delicate plants require strict humidity boosts while you are away, the Levoit Classic 300S is always there to back you up.


  • Excellent smart control capabilities
  • With remote and voice control features
  • The transparent tank shows the water level
  • Monitor humidity on your smartphone
  • Powerful performance
  • Customizable humidity


  • One of the more expensive choices
  • Almost as bulky as the TADLIATIV

4. Ledonti 4L WiFi Smart Cool and Warm Humidifier

If a six-liter humidifier is too bulky for you, the Ledonti is two liters smaller.

It could be the perfect fit for your requirements.

It measures 12.3 by 7.5 by 7.3 inches and weighs 3.34 pounds.

Its four-liter water tank is enough for spaces up to 300 square feet, and it offers up to 20 hours of humidification.

The Ledonti offers five operation modes: auto, constant humidity, high, medium, and low misting.

You can adjust the optimal humidity level between 40 and 90 percent for the auto mode function.

Additionally, the device has a timer that is adjustable for up to eight hours of continuous operation.

Like the Levoit, the Ledonti features remote control functions through a home network connection.

This feature allows you to set up schedules, adjust humidity settings, and put the device in Sleep Mode with much ease.

It also keeps its noise levels below 30 decibels.

Unlike the Erie and the Levoit, the Ledonti is only available in a single design and color.

Nevertheless, it is the only option that offers cool and warm misting for more specific needs.

Other features include:

  • A top-filling tank
  • An aroma box with a built-in diffuser
  • A 360-degree rotatable nozzle
  • A replaceable ceramic water filter


The Ledonti has the most advanced and all-inclusive features among our product options.

However, these hi-tech features come with a slight disadvantage.

In addition to the reduced tank capacity, the Ledonti costs more than any alternatives presented in this list.

Nevertheless, if you have the cash to spare, the features compensate for the higher price.

Making this purchase is especially beneficial for plant nurseries and home gardens containing plants that are highly susceptible to dryness.


  • The only option with cool and warm options
  • Odor-reducing and water-purifying
  • Excellent for cold and discomfort relief
  • Easy to clean
  • Effortless refills


  • Most expensive option on the list
  • Single design, no other color options

5. Lerat 1.5L Ultrasonic Cool Mist Humidifier

best humidifier for plants

If you only need to mist a small area with plants for no more than 12 hours daily, the Lerat Humidifier is an excellent option.

It has a 1.5-liter capacity that can last that duration, maintaining relative humidity between 30 and 50 percent.

The device measures 7.24 by 5.31 by 7.48 inches and weighs 1.79 pounds.

It only has two operation modes: high and low but does not have an auto mode or timer function.

Still, the high mist mode can last up to 10 hours on a single refill, while the low mist mode stretches to 12 hours.

The only extra feature you will find on this device is its interchangeable seven-color night lights.

If you need to choose, the Lerat comes with transparent blue and clear plastic tanks.


The Lerat is the most straightforward option on this list.

Its operation is as simple as filling the tank, switching it on, and choosing a mode.

If you just need to increase the moisture in the surrounding air, this device is more than enough.

Since it maintains its noise levels a little above 30 decibels, it is perfect for use at night or in the bedroom.

Its capacity to convert water into vapor for up to 12 hours can benefit indoor plants.

However, the lack of smart features may be off-putting for some consumers.


  • Simple operation
  • One of the more affordable options
  • More capacity than the Erie
  • Doubles as a multi-color lamp


  • No smart controls and remote operation
  • The shape is prone to tipping over
  • Inefficient 360-degree rotation of the nozzle

Which Is the Best Humidifier for Plants?

Don’t confuse an air purifier with a humidifier. While both provide functions for improving indoor air quality, they have very different effects on the growth of plants.

You will need the best humidifier for plants to have enough moisture in the air.

With that said, the most practical solution for a small set of plants is the Geniani Erie.

On the other hand, if you want to bring your indoor gardening to a larger scale, you might need something like the Levoit Classic 300S.

Then again, if a six-liter humidifier is too much, the Ledonti 4L should be a perfect match.
