Indoor Plant and Clean Air Studies
NASA did a study back in 1989 on their space stations to test if household plants help improve the air inside our home. The study found that some air quality plants helped remove volatile organic compounds or VOCs.
These dangerous VOCs include trichloroethylene, xylene, toluene, and carbon monoxide. Bill Wolverton conducted this NASA study, and the results found that the bigger and leafier the plant, the higher results for air purification.
Although there is a lot of air inside our homes and no one is quite sure how many it would take to cleanse it entirely, there’s no denying that you might want to start searching for the best plants for air purification for your house.
Read on to discover the best way to clean indoor air the natural way – with beautiful plants.

Weeping Fig (Ficus benjamina)
The Ficus tree, or weeping fig, is one of the most common indoor plants for air quality. Spot them inside offices, home, and interior commercial landscaping.
Weeping figs have lots of glossy, dark green leaves that act as air purifiers and make it one of the best plants for improving indoor air pollution. Keep weeping figs pruned three to six feet tall and in slightly acidic soil.
They require a bright room with lots of indirect light or some direct sun every morning. Keep the plant moist without getting too wet. They do best in daytime temperatures between 75°F and 85°F.
Favorite Household Plants for Clean Air: Philodendron (Philodendron bipinnatifudum)
Philodendron plants have remarkable, lilypad-shaped leaves that bring the jungle indoors. Philodendrons grown indoors come in both a climbing and non-climbing variety.

Chrysanthemums are standard flower purchases in the fall but are also plants for indoors that are excellent plants for air quality. Household chrysanthemums have a range of colors and require low light compared to other indoor plants.

Boston ferns are some of the best plants for air purification but have specific needs. These ferns are native to Mexico, Central American, and South America. They grow an average of three feet tall and wide, although some reach seven feet tall.
When you have Boston ferns as household plants, give them plenty of humidity during the winter. Keep the soil damp and check it daily to ensure it is adequately hydrated. Look out for spider mites and mealybugs and treat them as quickly as possible if spotted.
Aloe Vera (Aloe barbadensis)
Aloe vera plants are widely known indoor plants for improving air quality. Aside from their air purification properties, they are useful to relieve pain from burns and scrapes.
These plants for apartments or elsewhere have succulent leaves that are long and green with little spikes. Plant aloe vera plants in a pot made of a porous material, like terra-cotta, to encourage the soil to dry entirely between each watering session.

Snake plants are true low light houseplants that prefer to have part shade or minimal light conditions. They thrive in sandy soil types that have lots of drainage and are slightly acidic. Reduce watering during the winter as too much kills the plant.
Bamboo Palm (Dypsis lutescens)
Bamboo palms make a home feel warmer and more colorful. These tropical plants grow in conditions that most household plants won’t and reach mature heights of 12 feet tall. They have dark green leaves that grow on top of sturdy shoots.
