Improve Indoor Air Quality with Houseplants

Indoor houseplants act as a natural air filter, cleaning the air and removing harmful pollutants from the air.

NASA conducted a study in which plants were tested for their ability to create oxygen and filter toxins. The intent of the study was to find the best plants to filter air in the space station. The study produced a list of the plants they found  filtered the air the best and recommended having 15-18 “good-sized” plants in a 1,800 square foot home.


The following plants made the top of the list:

English Ivy

Spider Plant

Devil’s Ivy

 Peace Lily  

Chinese Evergreen

Bamboo Palm or Reed Palm

Snake Plant or Mother-in-Law’s Tongue

Heartleaf philodendron

Selloum philodendron

Elephant ear philodendron

Red-edged dracaena

Cornstalk dracaena

Janet Craig dracaena

Warneck dracaena

Weeping Fig

Gerbera Daisy

Rubber plant

When choosing a houseplant remember to choose a plant that matches the growing conditions of your home. For example, you wouldn’t want a plant that requires full sunlight in a shady corner.  Do you have houseplants for their air filtering potential or for the ambiance it adds to a space?
