For all of its exploration of the galaxy, the space program has accrued many benefits right here on earth. Thanks to NASA, we know that houseplants can purify the air in our homes and workplaces.
NASA originally focused on finding ways to purify the air in orbiting space stations. A 1973 space mission identified 107 volatile organic compounds, or VOCs, that were emitted by the synthetic materials inside the spacecraft. It was clear that tightly sealed buildings, whether orbiting in space or on the ground, could cause health problems.
Sick building syndrome
Back on earth, spurred by the energy crisis of the 1970s, the building industry focused on making old and new structures more energy efficient. Without intending to, they also paved the way for trapping pollutants – or what is often called “sick building syndrome.”
Three of the pollutants found in spacecraft – benzene, formaldehyde, and trichloroethylene – also are present in homes and offices, emitted by everything from building materials to furnishings to office equipment. Air-tight buildings conserve energy and reduce heating and cooling costs, but they also trap these pollutants.
NASA found that certain houseplants, because they are good at absorbing gases, could remove indoor pollutants. Researchers suggested using one potted plant per 100 square feet of home or office space to improve indoor air quality. One study found that philodendron, spider plant and golden pothos removed 80 percent of the formaldehyde that was introduced into a sealed chamber.
If you want to improve the air quality of your space, you might consider bringing home some of these commonly recommended plants:
1. Heartleaf philodendron
2. Elephant ear philodendron
3. Cornstalk dracaena
4. English ivy
5. Spider plant
6. Janet Craig dracaena
7.Warneckii dracaena
8.Weeping fig
9. Golden pothos
10. Peace lily
11. Selloum philodendron
12. Chinese evergreen
13. Bamboo or reed palm
14. Snake plant
15. Red-edged dracaena
