Boston Fern

(Nephrolepis exaltata)
First popularized during the Victorian era, the Boston fern features feather-like leaves and curved fronds that are well suited to indoor hanging baskets. It's considered one of the most efficient air purifiers, but it can prove a bit difficult to maintain because of its need for constant moisture and humidity.

How it Helps: This fern works especially well in removing formaldehyde, which is found in some glues, as well as pressed wood products, including cabinetry, plywood paneling, and furniture. (Some studies also show it can remove toxic metals, such as mercury and arsenic, from soil.)
