Are you tired of seeing your plants wilt away due to dry air? Then it’s time to install a humidifier for your home. They will not only maintain your plants’ health but you as well!

Types of Plant Humidifiers

Humidifiers for plants have three distinct types and varieties

  • Warm Mist Humidifiers

These are the most sold humidifiers and are easily available in the market. The mechanism that they employ is fairly simple the water is heated up to a certain temperature which is then turned into mist. The mist then blends in with the atmosphere and increases the humidity.

  • Ultrasonic Humidifiers

Ultrasonic humidifiers use high-frequency vibration (ultrasonic) to promote the evaporation of water. The vibration evaporates the water, producing extremely fine water droplets. 

Ultrasonic humidifiers are usually a bit more expensive than evaporative humidifiers, they don’t need to change filters, and they are quieter. Since the ultrasonic waves turn the water into mist without heating the water, there is less risk of burns from leaks. 

The downside is that there is no heat which normally inhibits the growth of bacteria and mold and requires you to sanitize your equipment regularly to avoid contamination. 

  • Evaporative Humidifiers

The evaporative humidifier uses airflow through a fan to draw water through the wet wick and produce mist. It comes with a filter that needs to be replaced on a regular basis to prevent the growth of mold and bacteria. Although these types of humidifiers are cheaper than humidifiers that use ultrasonic technology, they can be a bit noisy when operating because the fans move air to produce moisture.

Run time According to your needs, they generally need a run time between 12 to 24 hours. Refilling can be a hassle so be sure to check the minimum and highest run time offered by that particular humidifier.
