House plants that reduce humidity levels

Updated April 17, 2017

Humidity levels play a significant role in a person's health. In buildings or homes, high relative humidity can cause several problems. Mildew and moulds grow when relative humidity goes beyond 75 per cent. Dust mites propagate faster in surroundings with high humidity levels. Some house plants can reduce humidity. A few to consider are the reed palm, peace lily, English ivy, Boston fern and tillandsia.

Reed Palm

The reed palm can help purify the air and reduce moisture. This house plant is capable of surviving in relatively low light. However, it can grow tall, especially when placed in a bright area. It will thrive in warm temperatures.

Peace Lily

Popularly known as flexible plants, the peace lily can thrive indoors or in a garden. As a house plant, it requires watering at least once a week, but it can dry quickly during summer. It can grow in warm areas and can help reduce humidity levels since it requires moisture to flourish. The peace lily filters benzene, trichloroethylene, acetone and formaldehyde.

English Ivy

English ivy can remove airborne moulds, as well as formaldehyde, from the air. It comes in different shades, forms and colours. Ordinarily, English ivy is nurtured as a hanging plant. Gardeners also can cultivate it over moss to create captivating "living sculptures."

Boston Fern

An effective air purifier, the Boston fern helps to balance humidity levels by absorbing moisture from the air. It eliminates formaldehyde and thrives in warm and humid environments. This house plant prefers daytime temperatures and lots of indirect sunshine. It is a popular house plant that can grow in hanging baskets.


Often called an "air plant," tillandsia is an ideal plant for environments with high humidity levels. This house plant absorbs nutrients and moisture through its leaves. There's no need for it to be nurtured in soil, and it requires little water and sunlight.
