Note that the steam quality changes according to the water you put in the humidifier. There have been complaints about white residues appearing in this humidifier when using hard water. Therefore, you may need to use distilled or purified water when using this humidifier.

Sometimes the steam coming out of the product may go down instead of going up. This shows that you need to be careful where you put the product. Try not to put it next to products that should not be moistened.

#4 Best Smart: LEVOIT Top Fill Cool Mist Air Ultrasonic for Plants Indoor

Thanks to USB charging, you can charge it either on your computer, in your car, or by using adapters with USB inputs.

As with all small-sized humidifiers, the steam level of this humidifier is slightly lower than average. Therefore, it may not be suitable for use in large areas.

Although it says in the product description that it can work up to 8 hours, the average working time is 4-5 hours. Therefore, this may not be suitable for all-night use either.

Just as the human body needs humidity, plants also need humidity. Especially in indoor plants, the lack of humidity caused by the house temperature’s dryness causes your plants to wither and dry out. Just as the dry air in your home makes your skin dry and you feel uncomfortable, the same is true for your indoor plants.

So is purchasing a humidifier the only solution that will provide the necessary humidity for your plants?  

If you ask yourself, “How can I humidify my room without a humidifier?” there are many options here! Let’s take a look at the ways you can provide humidity for plants!

1. Get Power from Pebbles

When the dryness of your plant’s leaves gives you the first signals, the pebble tray may come to your rescue. A very common method, the pebble tray consists of a container filled with gravel on which you can put your plant with its pot. Since direct watering to your plant may cause it to suffocate sometimes, adding water to the pebbles and placing your plant on it will ensure that your plant receives as much water as it needs. At the same time, it will continuously meet the humidity your plant needs.

What you need to pay attention to here is to care about the moss-prone structure of pebbles. Observe the pebbles and clean them frequently if possible. If you cannot intervene at the right time, you may have to fight bad smells.

2. Benefit from the Humidity of Your Bathroom

Humidity in the bathroom can be great for your plants. Our baths in which we are in contact with water are susceptible to humidity, and plants can also benefit from this moisture. If you have enough space in your bathroom, you can put your plants. To make room for your plants, purchasing portable shelves might be a good solution.

Here, it would help if you were careful not to expose your plants to too much humidity. If you do not have a window in your bathroom or do not receive sunlight, it would be useful to keep your plants in your bathroom one day and then in a sunny room instead of constantly keeping them there.

3. Mist Your Plants

Does misting plants increase humidity? One way to add humidity to your plants is to mist them. First of all, you should know your plant structure about steaming.

Fill a spray bottle with rested or distilled water and spray the leaves. The purpose here is not to water your plant but to steam it up. In this method, which you can apply several times a day, you will help your plant absorb humidity directly from its leaves. Proceed by observing the changes in your plant. Sometimes, after spraying your plants, you may need to wrap them in a ziplock bag. Check your plant’s growing conditions to be sure of this.

4. Increase Humidity by Bringing Your Indoor Plants Together

Another method that increases the humidity power is to bring your plants together by determining an area where your home can get both sun and humidity. Plants absorb humidity even when they are together. Although it is visually impressive to have plants in every corner of your home, the humidity required for your plants is only possible when they are together. While many users prefer to group on the ground for stunted plants that do not grow leaves, some prefer cabinet tops, bookcases, or special shelves for long-leafed, cluster plants.


When you want to buy a humidifier for your plants, you will come across many different models. Each model is also equipped with different features. It is difficult for you to develop a purchasing behavior on a subject; you have no previous knowledge. We have explained the humidifier types to help you determine the best humidifier type!

1. Cool Mist Humidifier

A cool-mist humidifier is a type that uses little electricity. These are ideal species for use in homes with children and pets. Because it is more protected from accidents caused by humidifiers using boiling water.

2. Ultrasonic Humidifier

Ultrasonic Humidifier is the most silent type. In general, these are affordable models that can be preferred in growing rooms and produce cold mist, as you can see. When choosing this type of humidifier for your plants, we recommend that you consider your room size because devices produce high humidity levels.

3. Evaporative Humidifier

It is a noisy humidifier type with invisible humidity output and a fan system that requires constant maintenance. These devices, which produce humidity using the growing rooms’ airflow, also have a wicking filter. As such, you should not disrupt its maintenance to ensure a stable humidity output.


You can perceive that the plants you grow indoors are not just images, but from the air they clean. But growing plants is a mutual relationship. When you don’t provide the moisture your plant needs, only a one-sided care responsibility remains.

To avoid this problem, we have listed the best humidifiers for plants. So what should you look for when choosing a plant humidifier? You can make the right choice by checking out our buying guide!

Image by Qwart

Humidifier Capacity

Plant humidifiers’ capacity is a criterion that should be selected according to the types of room and plants in which you will position it. Because every plant needs different humidity, before you buy a humidifier, determine your room size; small humidifiers will do if you have 300 square meters. If you have more square meters, a medium-sized humidifier will work for you.

When it comes to the capacity of your device, you should look at its gallons. On average, a three-gallon appliance will provide approximately 800 feet of moisture. Every gallon that increases means an equal amount of increasing square feet.

Besides, this capacity also gives you a clue about the operating time of your device. If the device contains a 12 or 24-hour recharge, it means you have chosen a good device.

Water Tank Size

The size of the water tank, which shows how often you need to fill water during the day, is also related to how large its area will serve, as we mentioned above. If you use a humidifier in the growing room, you will expect it to distribute humidity more. The larger the water tank, the less often you will need to fill it.

Noise level

These devices have a fan system inside. It can be a little loud when the fan is running. Fortunately, there are also silent ultrasonic humidifiers that you can choose from in your bedrooms and even in baby rooms. Although not as loud as heavy-duty machines, a noiseless device may be the criterion for those who prefer a quiet life.

Built-in Humidistat

This feature is designed to shut down the device when your room’s correct humidity level is achieved and keep the humidity at a certain level. Humidity meters in humidifiers prevent health problems caused by excessive moisture. It is a good feature against mold that may form over time. It is also necessary to obtain the right level of moisture for your plants. If you already have a humidifier available and this feature is not available, you can use a moisture meter for plants.


Where Should a Humidifier be Placed in a Plant?

Because the humidifier uses a fan, you should not place it near your plants. The distance you need is at least three feet from your plant so that the moisture is evenly distributed throughout the growing room. It would be a good way to choose corners as the moisture will be more dispersed in small rooms. So you should place your device in one corner of your room and your plants in the other corner.

Are Diffusers and Humidifiers the Same?

Another issue that is frequently wondered by people is whether diffusers and humidifiers are the same. Although they look the same, the purpose of working on both devices is different. Diffusers can work with essential oils to change the atmosphere of the areas where they are used. Diffusers are suitable for use in problems such as throat dryness and clogging. But you cannot add humidifiers to essential oil. They only work to remove the dryness of the areas and restore the correct moisture level. It would help if you preferred humidifiers, not diffusers, to give the moisture that plants need.

Is Warm Mist or Cool Mist Better for Plants?

Depending on the area’s temperature where you will grow your plants, you prefer a warm or cool air humidifier. Seasonal temperature changes are also effective in this choice. For example, they are hot air humidifiers that will humidify the dry air in winter. In the sweltering heat of summer, cold air humidifiers provide the right humidity for your plant, which is exposed to high temperatures. Both moisturizers are ideal for the humidity of plants. Of course, when they are positioned correctly and maintained regularly.

Can Humidity Kill Plants?

The humidity required for plants is effective in their development and healthy appearance. However, there is an ideal humidity percentage for each plant. More than this percentage will cause fungus formation in plants; in short, your plants will get sick. If we give a general ratio, the ideal humidity percentage is 50% – 60%.


Even though indoor plants may seem like a part of a hobby, they are often a supporter of human health. Plants that contribute both psychologically and physiologically need humidity like humans. It would be the right decision to buy a moisturizer so that the simple methods you can apply at home can be more permanent and healthy.

Now, you know the best humidifiers for plants in 2021. These humidifiers consist of the best in different categories with high performance, fully meeting your needs. Among them, Pure Enrichment MistAire Ultrasonic Humidifier was at the top of our list that was the best for our plants.

So which one will you choose? What methods have you tried to humidity your plants before? Come on, share your experiences, opinions, ideas, and suggestions with us!
