Sharing is caring!

Those who love indoor plants are acquainted with the traditional methods of caring for green plants. Essentially, this includes loosening the soil, competent watering, and spraying the plant leaves with a unique sprayer. 

But even with stringent observance of the rules, the plants sometimes get sick, dry, and turn yellow, buds and flowers fall off, and the leave tips become wrinkled and brown. All these signs represent the low air humidity. To solve this, you need the best humidifier for plants.

These humidifiers have a stylish design, easy to operate, and are reliable. You set the desired humidity level in the room and automatically maintain it. The ceramic filter cartridge of these best humidifiers for plants performs water treatment from various impurities.

The air ionization function is provided separately, which is especially useful in winter, and if there is a computer or other electronics in the room. Some humidifiers will notify with a signal that the tank has run out of water and will automatically turn off until you fill it up again.

Likewise, the filter sorbent does not allow the reproduction of harmful microorganisms in purified water. There is the dual-nozzle atomizer that rotates in a circle so that you direct the steam in the way that suits you best.

Types of Humidifiers for Plants

1. Steam humidifiers

Steam humidifiers operate based on a steam humidification system. These are pretty simple humidifiers that consume a lot of electricity, with high performance and power (200-500 W).

This is the main functional block of heating elements that convert water into steam. Humidity increases very quickly and is maintained constantly. When the optimum level is reached, the humidifiers turn off.

Such humidifiers create a stable environment for comfortable growing plants in medium and high humidity levels (often no more than 60-70%). They do not allow you to control specific indicators, but they solve the problem of extremely dry air quickly, efficiently, and reliably.

2. Ultrasonic humidifiers

Ultrasonic humidifiers are high-efficiency and medium-power humidifiers (up to 150 W). This works to convert electrical vibrations to a piezoelectric element’s vibration to produce fine water mist. 

Such humidifiers are equipped with high-quality hygrometers, which will allow you to quickly achieve and maintain the desired performance without the constant operation of the device. These are the only humidifiers in which the humidity readings can be precisely adjusted.

And besides, like steam models, they are often equipped with control programs, precise humidity controllers, and a flavoring function. It is challenging to find shortcomings in ultrasonic humidifiers, and they all relate to water quality.

The ultrasonic humidifiers work only with distilled water. Even if there is a cleaning function when using ordinary water, you will have to constantly change the elements and drain the water after work.

3. Cold acting humidifiers

Cold acting humidifiers, also known as cold action humidifiers, are devices in which air is driven through filters and cartridges immersed in water, saturated with moisture efficiently and evenly. 

Unlike steam humidifiers, these are low-power appliances (up to 60 W), capable of performing the functions of a humidifier on an area of ​​150 square meters.

Cold acting humidifiers are safe, easy to use, and slow but very effective humidifiers. They can saturate the air with moisture two times slower than steam humidifiers.

To achieve even an average humidity of 60-70%, you will have to wait many hours. Still, the stability of the environment is much higher, as is the uniformity of the distribution of humidity indicators.

4. Air washers and climate systems

Air washers and climate systems are household appliances used for their own needs, not specifically for indoor plants. Improving their conditions is instead a pleasant bonus of the operation of climate complexes.

Factors to consider when buying the best humidifier for plants

Operating modes

When buying the best humidifier for plants, you need to consider the operating models. If possible, you can choose the intensity of the operation of the humidifier, on which the energy consumption and noise level depend.

For example, the turbo mode will allow you to quickly reach the desired humidity in the room, and the night mode will allow you to maintain an optimal microclimate.

Automatic settings in multifunctional climate complexes help to adapt to your rhythm using Smart eye sensors, the Econavi system, etc.

Availability of sensors

These can be the response devices located in the tank. When the water level drops to the limit, the humidifier turns off and signals to fill the tank.

Humidity sensors notify the state of affairs in the room and allow the humidifier to turn on when the parameters decrease automatically. This is an essential factor you need to consider.

Served area

When choosing the best humidifier for plants, the main feature you should pay attention to is the served area. In most cases, it is assumed that one humidifier should humidify the air in one room.

For example, if the room area is 20 square meters, you need a model with a case and a capacity of not more than 5 liters.

There are also larger options, for example, about 7 liters. In this case, the serviced area will be much more significant. In any case, it is better to buy a humidifier based on its work area so as not to waste money and not overpay for extra performance.

Power and space

When choosing the best humidifier for plants, you must always consider the level of power consumption. This indicator indicates the amount of electricity consumed by the humidifier during operation. 

The power of modern air humidifiers varies from 30 to 150 watts. The power level of the humidifier for plants must be selected based on the area of the room and the frequency of use. 

For rooms with an area of ​​25-60 square meters, it is recommended to use humidifiers with a power of at least 100 watts. For standard rooms in apartments and residential buildings (10-25 m2), low-power models will also work.

Regardless of the power level, it is worth remembering that the humidifier can effectively humidify only one room. To maintain the required humidity level in the entire apartment, it is necessary to use several devices.

Noise level

A crucial factor for choosing the correct humidifier is the noise level of the device. This indicator is not so important during the daytime, but you may want to leave the humidifier turned on at night.

In this case, the noise level is of great importance. If you are thinking about which humidifier to choose, it is best to look at models that operate at levels up to 35 dB. Such a humidifier will not interfere with sleep, as it does not exceed the level of a usual whisper.

Water consumption

To choose the suitable humidifier model, give preference to a device with an average water flow. This parameter is crucial. In this case, you should be aware that humidifiers with a small flow rate are inefficient.

They take a long time to increase the humidity to the required level. An indicator of 250 ml/hour is considered insufficient.

According to reviews of humidifiers on popular forums, the flow rate is 450 ml/hour. Such models are designed for a large area and will cope with their task in 2 hours in a small room.

Cold or warm evaporation

A cold evaporation humidifier adds moisture to a room by spraying cool vapor. Such a device is suitable for those who live in areas with a warm climate or during the summer. 

Accordingly, a humidifier with warm steam is more suitable for residents of a cold climate. Some warm vapor models can be used as inhalers.

Built-in hygrometer and hygrostat

When buying the best humidifier for plants, you need to build in hydrometer and hygrostat. A hygrometer measures the humidity of the surrounding air. The built-in hygrostat will allow you to adjust the humidity in the room and automatically maintain it at a given level.

Cleaning and maintenance

Make sure the humidifier is easy to clean; otherwise, it will become a source of bacteria. Some humidifiers models need daily filling with rinsing and water. Filters need to be cleaned frequently and replaced promptly. Expensive models are equipped with filters that do not require replacement.

Price

When calculating the budget, consider the cost of purchasing the humidifier for plants and the cost of operation and maintenance. 

Cold evaporation humidifiers require the addition of an antibacterial additive to the water. Models with replaceable filters and cartridges will require periodic replacement of these parts.
