Humidifiers For Houseplants (The Ultimate Buying Guide)

While most plant parents can pick humidifiers by simply considering how easy the humidifier is to move around and if it can keep your plants hydrated in the past. But now with so many humidifiers on the market, you have to put other vital factors into consideration. Below are factors to guide you in choosing a reliable humidifier for your houseplants.

1. Humidity Levels

One thing you want to make sure of is that you choose a humidifier that won’t release too much or too little moisture that can harm your plants. Hence, it is advised that you choose humidifier models that are designed to gauge the ambient humidity and temperature level in the room. Choose ones that come with high and low humidity settings, so you can adjust the mist accordingly.

2. Room Size

The room where you plan to place the humidifier is going to play a role in the size you get. The plant’s humidifier moisture output has to match the size of the room they are placed in. So putting the room under consideration helps you choose one that can regulate moisture across the room properly.

3. Noise Level

While the noise might not have any effect on your plants, it will on you especially if you are placing it where you sleep or work. Some plant humidifiers are loud while some units are designed with quiet operation.

4. Tank Capacity

The tank capacity is just as important as the room size. The bigger the tank happens to be, the longer the humidifier will be able to run uninterrupted. Constant refilling can be stressful so if convenience is the goal then it’s best to choose a humidifier with a large tank capacity which equals longer runtime.

5. Setup And Maintenance

This is a very important factor to put into consideration. Cleaning and proper maintenance are important for all types of humidifiers, it keeps them running and if left uncleaned and unchecked for too long, it causes mold buildup. Mold being released in the mist can cause allergens or respiratory illness hence it’s vital to choose a humidifier that is easy to clean and care for.
