4. Peace Lily
Peace lilies love the shade, so they’ll do just fine even far away from a window. This eye-catching variety is also one of the best plants for improving indoor air quality, according to NASA research.
A 1989 study published by B.C. Bill Wolverton, an environmental scientist working with NASA and the U.S. military, concluded that peace lilies removed more VOCs from the air than nearly any other houseplant.
Since then, its cleansing properties have been recognized by researchers at the University of Minnesota, Penn State University and National Chin-Yi University of Technology in Taiwan, just to name a few.
Care instructions: Plant your peace lilies in rich, loose potting soil, and make sure the pot provides adequate drainage. Check the soil every few days and water as necessary. To ensure healthy leaves and frequent flowering, never allow the soil to dry out.
