The Best Humidifiers For Houseplants (Create A Jungle Atmosphere)

If you buy something using the retail links in our articles, sometimes we earn a small affiliate commission. This does not impact the products we recommend.

Many houseplants have naturally evolved to grow in conditions of high humidity and can suffer and even perish when exposed to low levels of water vapor in the atmosphere.

Just a 10% swing in humidity can make all the difference between a plant just surviving and one that is thriving. Orchids for example grow best in a humidity of between 50% -70% which is difficult to achieve if you live in a warm dry state such as Arizona, where humidity regularly dips to 10% and below at the height of summer.

A humidifier such as the designer Honeywell HUL430W is a handy piece of kit as it puts you in control of the concentration of water vapor in air surrounding your houseplants, and creates the optimal humidity in each of your rooms. By doing so you can establish the ideal conditions to allow your indoor plants to thrive.
