Now, let’s begin!

Best Humidifiers For Plants

Humidification for cultivation of flowers. The steam from the air humidifier in the room.

Here is the list of the 5 best humidifiers for plants that you can use to maintain the ideal level of moisture in your home and keep your plants healthy.

1. LEVOIT Classic 200S Humidifier – Best for Smart Home Integration

Let’s get things started with the Levoit Classic 200S Humidifier. Featuring a compact and certified-safe design, its diffusing capacity is ideal for humidifying almost any room in your home or office. Plus, it won’t burn a hole in your pocket.

Why Did We Like It?

At first glance, we really liked its minimalist and sleek design, which won’t require a lot of space. The top of the humidifier is detachable, and removing it will expose the mist outlet tube. You will also find a carry handle to remove the 1.05 gallons tank for refilling purposes. 

We appreciate the dual 360-degree nozzle that’s meant to direct the vapor away from sensitive items like electronics and upholstery. Despite using it continuously, there were no signs of dampness in the surrounding areas. Moreover, it operates on three different levels, viz., low, medium, and high, which can be controlled by tapping the power symbol twice.

Depending on the setting, the tank lasts anywhere between overnight and 40 hours, which is mighty impressive for its size. Not only that, but the device automatically shuts off on an empty tank and resumes operation at the same level when refilled. 

Finally, the low sound level can be credited to the silencer that can be removed for maintenance.

What Could’ve Been Better?

There’s a small essential oil tray located at the back where you can add your favorite fragrance to make it work as a diffuser. And that’s the only aspect we’d like to improve as we ended up using more products to keep the room fragrant. But considering it’s a humidifier and not a diffuser per se, this inconvenience can easily be neglected.

  • Can be paired with smart control devices
  • Light indicator turns off after 30 seconds
  • Easy twist cap for filling the water tank
  • Low 25dB sound output
  • Doubles up as a diffuser
  • Low fragrance diffusion
Dimensions: 6 x 8 x 14 inches | Weight: 3.5 pounds | Power Source: AC | Runtime: 40 hours | Capacity: 4 liters | Coverage: 376 square feet

2. GENIANI Portable Small Cool Mist Humidifier – Best for Portability

Next up, we have this portable mist humidifier from Geniani. With a super-affordable price tag, its lightweight and compact design can fit in cramped spaces. What’s more, the simple one-button control does away with complicated settings for quick operation.

Why Did We Like It?

Affordability aside, we were encouraged by the positive customer feedback to try this product, and we’re glad we did. The device essentially comprises two parts, i.e., the nozzle-integrated sturdy top cover and the refillable tank base. 

All you have to do is unscrew the former clockwise and fill the 250ml clear tank for refilling, which should then last for a full night or office day. Furthermore, the no-spill design means you don’t have to keep a constant watch on the placement.

Beyond that, the one-touch button control is ideal for users who don’t want the hassle of multi-key operation. The same button will power the device and change the misting mode for continuous or intermittent misting. We tried both modes and were impressed with the moisture level.

A great side feature is the optional night light, which offers just the right illumination for a cozy ambiance without affecting the runtime. And lastly, the humidifier comes in a larger variant for heavy-duty use.

What Could’ve Been Better?

The GENIANI Portable Small Cool Mist Humidifier doesn’t need extensive maintenance, but we’d still have liked some clear instructions and a compatible cleaning brush for those occasional cleaning sessions. Other than that, we don’t have any complaints about this excellent product.

  • USB powered, package included USB cord
  • Auto shutoff feature to prevent dry run
  • Less than 30dB sound output
  • Dual mist modes
  • Available in black, white, and 4L tank variants
  • Cleaning material not included
Dimensions: 9.06 x 6.69 x 12.2 inches | Weight: 4 pounds | Power Source: Corded electric | Runtime: 40 hours | Capacity: 4 liters | Coverage: 376 square feet

Ideal for both nurseries and workspaces, this humidifier operates quietly and safely. Its bottom-fill tank is designed for easy maintenance and cleaning, while the handy built-in handle enhances portability.

Indoor plants benefit remarkably from this humidifier as stable moisture levels are critical for their well-being. This device helps maintain the desired humidity, resulting in robust plant growth and overall health.

What Could’ve Been Better?

Why Did We Like It?

It offers a unique combination of design and performance that sets it apart from its competitors. With its slim, cylindrical shape, the humidifier fits well on crowded bedside tables, desks, or nurseries, saving valuable space while providing adequate moisture to the environment. This device runs for up to nine hours, a much longer runtime than other mini models available in the market.

One of the main features of this humidifier is the user-friendly dial knob on the front, allowing users to quickly and easily switch between low and high settings and control the mist output. It also comes equipped with a convenient water level indicator and an automatic shutoff function when the water runs out, ensuring safety and ease of use.

Another significant advantage of this humidifier is the noise level making it quiet enough for babies, children, or light sleepers. Though there are quieter units available, the raydrop Cool Mist Humidifier provides a comfortable noise level for most individuals.

What Could’ve Been Better?

While the Raydrop Cool Mist Humidifier offers numerous benefits, one of its drawbacks is the small tank size. Due to its compact design, it requires daily refilling if you plan to run it every night. However, its small size also makes it easy to refill, which offsets this minor inconvenience.

What Could’ve Been Better?

Buying Guide For The Best Humidifier For Plants

The amount of moisture and duration for which the humidifier should run will vary according to the plant type. But irrespective of these factors, there are some other features to consider before making the purchase. Hence, we’ve listed down those points for your convenience.

Room Size

One of the first things to look out for is whether your preferred humidifier is suitable for the room size. Since most brands specify the coverage range, we’d strongly recommend not relying on approximations. The last thing you’d want is too much or less moisture for your beloved greens!

Run Time

An important thing to note regarding the runtime is the corresponding mist setting. Considering that you’d gradually want to add moisture to your plants, we’d suggest checking out the runtime on the lowest setting and going for a model that lasts at least overnight on a full tank.

Auto Shutoff

From what we have observed, almost all models come with an auto shutoff feature to negate the risk of dry runs and overheating. While some humidifiers also come with an LED indicator, others may disengage operation directly if the water is depleted or the tank is removed.

Filter Cartridge

Some models come with a filter like the microporous cartridge for removing odor and impurities from the water. This is a useful feature for areas with contaminated water or if you don’t want the trouble of purifying water before filling the tank.

Diffusion Mode

In case you want to use your humidifier as a diffuser, make sure it’s meant for use with essential oils. Never use oil with a model that isn’t essential oil compatible as it can cause irreparable damage to the internal parts.

Additional Features

Among the most sought-after additional features are a carry handle, low-noise operation, nightlight, and sleep mode (for the complete shutdown of any LED on the device).

Frequently Asked Questions

How do I know if my plants need a humidifier?

Research your plant’s specific needs to determine if they require higher humidity.

Signs of low humidity may include curling, browning, or wilting leaves, excessive plant stress, and slow growth.

Can using a humidifier for my plants cause mold or mildew issues?

A properly maintained humidifier should not cause mold or mildew issues. However, poor ventilation or high humidity levels not suitable for the plants may lead to fungal growth.

Regularly inspect your plants and the surrounding area for any signs of mold or mildew to address potential issues promptly.

What type of water should I use?

Ideally, use distilled, deionized, or filtered water to minimize mineral and impurity build-up in your humidifier. Tap water may contain minerals that can harm your plants over time.

Where should I position my humidifier for optimal plant health?

Place the humidifier close to your plants, but not directly on them. Ensure that the vapor stream is spread evenly throughout the surrounding air, allowing the plants to absorb moisture without getting directly wet.

How often should I clean my plant humidifier?

It’s recommended to clean your humidifier at least once every 1-2 weeks to prevent bacterial and fungal growth.

Always follow the manufacturer’s guidelines for cleaning and maintenance.
