 Many people move indoor plants outside this time of year to reduce indoor humidity, but some types of plants can actually reduce the humidity in your home. The peace lily is a virtual air purifier. It absorbs moisture as well as dangerous mold and organisms. The reed palm has similar benefits, and it does well in shade and partial lighting. For humid air near the ceiling, try English ivy in a hanging basket. Entalansia is often called an air plant for its ability to absorb all the moisture and nutrients it needs directly from the air.
