It's not exactly rocket science, but NASA was still interested.

 

 

As part of a clean air study, NASA put together a list of air filtering houseplants in 1989, partly with an aim to send them out of this world and use them to help clean the air on space stations.

 

Thankfully this research can also help the grounded among us, as they can also be used to clean the air in our homes, help neutralise the effects of sick building syndrome, take in carbon dioxide, release oxygen, and absorb toxic agents like formaldehyde; benzene; xylene and toluene; ammonia; and trichloroethylene.

 

 

There are heaps of different and stunning plants on NASA's list, but here are 11 of our favourites.
