Types of Humidifiers

You can’t change the outdoor conditions that contribute to low humidity. However, you can control the humidity inside your home. A whole home humidifying system is great, but it’s not always the most economical (or practical) option. The right humidifier can boost moisture levels in the air in your home, benefiting both you and your plants.

The four most common types of humidifiers include the following: 

  • Evaporators 
  • Impeller Humidifiers 
  • Steam Vaporizers 
  • Ultrasonic Humidifiers 

An evaporator is powered by a fan that blows moisture through a moistened filter whereas an impeller humidifier utilizes rotating disks. Impeller humidifiers are more child-friendly than evaporators because they only use cool mist.

Steam vaporizers are powered by electricity — they heat the water then cool it before expelling moisture into the air. They’re generally one of the cheapest humidifiers but they aren’t the most child-friendly. Ultrasonic humidifiers, however, are very safe and they come in both warm and cool mist models. 

How to Use a Plant Humidifier

A portable humidifier is a great option for semi-tropical and tropical plants. These types require higher levels of moisture in the air. In order for your plants to receive the maximum benefit, however, you need to know how to choose the right humidifier and how to use it properly. 

Portable humidifiers come in a wide range of sizes. Measure the size of the room to choose an appropriate model. An evaporative humidifier is one of the best options because it filters the water so you don’t transfer anything to the plants. The filtering wick also prevents over-saturating the air because water simply won’t leave the wick if moisture levels are high enough. 

To use a humidifier for plants, it’s best to use filtered or distilled water. Even so, you’ll need to clean the humidifier regularly to remove mineral buildup as well as algae and bacteria that can grow in the reservoir. 

Place the humidifier a few feet away from your plants. Placing it too close can cause water to condense on the leaves and soil, creating an environment in which mold and fungus can thrive. Keep the humidifier elevated on a table or desk. Be sure to keep it well away from porous surfaces like fabric curtains and wood. Run the humidifier for at least 4 to 5 hours a day. The best time is in the early morning to midday.
