Use These NASA Approved Plants if You Want to Improve the Air Quality in Your Home

TODAY is atypical for our blog Article: let’s talk not about TECHNICAL assistants, but ON NATURAL – indoor plants. Could they affect the microclimate? Is there really a plant that purifies the air? WE UNDERSTAND.
It is widely believed that plants clean well and even “sterilize” and “disinfect” indoor air.

NASA, in fact, has studied the possibilities of plants for air purification. In 1989, a report was published entitled “Reducing Polluted Indoor Air Using Indoor Plants” (“Indoor Landscape Plants for Indoor Air Pollution,” available online). Scientists tested 12 varieties of plants. Their ability to filter three pollutants has been studied: benzene, trichloroethylene, and formaldehyde. Among the results obtained, for example, the following results:

Eliminate contamination in the test chamber within a 24-hour period.

“Indoor Landscape Plants to Reduce Indoor Air Pollution,” NASA 1989
Formaldehyde Benol Trichloroethylene
Dracaena Aroma 70 21.4 12.5
Chrysanthemum Garden 61 53 41.2
Gerbera 50 67.7 35
Dracaena Varunka 50 52 10
Ficus Benjamin 47.4 30 10.5

The numbers can really inspire, if not create a balcony garden, then at least water the cactus. But not so simple. It should be borne in mind that these data figures are achieved under test conditions. More precisely, the conditions were as follows: the plants were installed in a special chamber, where a continuous stream of water and light was organized. Of course, we do not keep plants in our apartments. But, more importantly, the camera used an activated carbon filter. In other words, the aforementioned effectiveness is the effectiveness of all equipped scientists of the system and not just the “green advocates”. The effectiveness in air purification of own plants is unknown.

In addition to these three, there are many other air pollutants that are widespread and harmful. Therefore, if you are seriously thinking about the microclimate, you should bet not on plants that purify the air, but on specialized devices. Does one Boer with a recycle function or a cleaner disinfectant replace the entire Ficus army?

In fairness, I must say that plants really have a certain effect on the micro climate. First, they absorb carbon dioxide and some other volatile compounds. By the way, with regard to carbon dioxide: part of it is released during the respiration of plants, as well as people and animals. Secondly, plants distinguish between volatile substances that resist microorganisms. And although claims that plants disinfect the air are greatly exaggerated, they still belong to some merit in improving the micro climate.

And for those who want to conduct their own tests, we have selected seven of the most suitable indoor plants for our latitudes.


One of the most unpretentious domestic plants. Judge for yourself: the bright sun does not require, you can even put it in the far corner of the room. In the heat is not necessary, only 20 degrees Celsius. However, the summer likes to “swim”: it is advisable to spray it abundantly and not leave the soil dry.
