Do Indoor Plants Really Clean the Air?

Sure, that potted fern is pretty, but can it really spruce up the air quality in your home? Studies by scientists at NASA, Pennsylvania State University, the University of Georgia and other respected institutions suggest that it can.

Plants are notoriously adept at absorbing gases through pores on the surface of their leaves. It's this skill that facilitates photosynthesis, the process by which plants convert light energy and carbon dioxide into chemical energy to fuel growth.
