Pothos is one of the best plants for removing formaldehyde in the air that comes from carpet and other materials in our homes. Beautiful, low-maintenance, and cleans the air. Glossy, heart-shaped leaves emerge green and become variegated with yellow or white. Although this plant tolerates low light well, its leaves may lose their variegation. Pothos will look its best in moderate or bright light. It makes an excellent office plant because it grows well under fluorescent lights.
