Since we know the plant does well in an environment with good humidity levels, it is, however, a responsibility to ensure that our house plant has the right humidity for better growing and living. In case, you don’t know the optimal range of humidity that is okay for an indoor plant, a 30 – 60 % range is what should be the right practice.

Bowl of water: This technique is usually a cost-effective way to increase atmospheric vapor levels because what you need is a bowl and water while placing it close to the plants. While this method is good, it may require time for the water to evaporate. Besides, the bowl can easily be kicked by anyone, especially if you have children.

How To Choose The Best Plant Humidifier You Desire 

What we discussed below are some important criteria to choose the best product for your in-house plant:

  • Size of the room: Rooms are of different sizes or dimensions. A small room is an enclosed space of not more than 300 square feet while large rooms are usually 500 sq. ft. measurement. Here is GENIANI Top Fill our best pick for small-sized rooms while for bigger rooms, we picked Everlasting Comfort. Nevertheless, the essence of knowing your room size is to help you buy according to your demand. Because investing in something lesser to the coverage area will result in an inefficient working cycle and vice versa. 
  • The right location: I know, you want to ensure humidity is reaching your plant sufficiently and that’s why you want to shop for a humidifier. Consequently, do not place the unit too close to the plant, a 1-meter distance should be allowed because humidifiers have fans that blow the moisture. When the unit is too close, can result in a draught, thereby leading to wilting.
  • Maintenance: It is very dangerous to run humidifiers without cleaning. When you do this, bacteria, germs, or molds will grow inside the tank and over time, the unit will disperse them alongside the mist it’s releasing, which will contaminate the air. To prevent such happening, thoroughly clean and change filters, if the unit you bought has one. Every manufacturer clearly states how and when (time) to clean their products. So endeavor to consult the user manual for this information. So the bottom-line, choose a product that can be easy to clean, maintain spending less cash and time.
