Regardless of the types of plants, indoor greenery not only adds beauty to your indoor spaces by adding an aesthetic appeal but also adds oxygen and removes allergens. However, most indoor plants require higher humidity levels than those found inside your home, especially during winter months when dry air is prevalent. This is especially true for those growing indoor tropical plants that thrive in their natural humid environments like monstera or orchids. Adding a humidifier to your home keeps your indoor garden of houseplants healthy and thriving.
Combating low humidity levels indoors not only adds health benefits during the colder months like warding off dry skin and sinuses but also adds much-needed moisture to your plants. Humidifiers release moisture into the air that indoor plants can absorb through their pores. Humidification of your indoor spaces keeps your indoor plants producing lush foliage and reduces cultural problems like browning and curling leaf tips.

You can easily raise indoor humidity levels by investing in a simple humidifier and we cover some of the important considerations that help in selecting the best one for your situation. There are a wealth of different types of humidifiers on the market and we've covered our top picks of some of the best humidifiers for plants.
What to Consider When Purchasing a Humidifier for Plants
Types of Humidifiers: When considering a humidifier, it's important to understand how the different units operate. Ultrasonic humidifiers utilize high-frequency (ultrasonic) vibrations to aid in evaporation. Extra fine droplets of water are produced as the ultrasonic vibrations steam the water. Humidifiers utilizing ultrasonic technology don't have filters you'll need to change but can be a bit pricier than those using evaporation. They also offer quiet operation compared to evaporative types.
Humidifiers using evaporation utilize the airflow to create a fine mist as the water is pulled over a wet wick by the use of a fan. Although these types of humidifiers are not as pricey as those using ultrasonic technology, they can raise noise levels due to the fan and require cleaning and periodic filter changes. Choices in evaporative types include warm mist humidifiers and cool mist humidifiers. The basic difference between the two is that warm mist humidifiers produce purer water vapor due to evaporation and those producing a cool mist are energy-friendly as they require less energy to operate.
Size of Room: It's important to consider the room size of the area you plan to situate the humidifier. If you purchase a humidifier that's too small, you won't increase humidity to adequate levels your plants require. Moisture disbursement levels will be lower and your plants won't have the ideal humidity levels they require for healthy growth.
Tank Capacity: The capacity of the humidifier's tank is proportional to the length of time it can run. Those with large tanks produce a long runtime without the need to stop the unit and refill it with water. However, small rooms that require less relative humidity can use smaller units.
