Good news for all you plant parents out there, new research led by the University of Birmingham has revealed that your house plants can reduce levels of nitrogen dioxide (NO2), a common pollutant, by as much as 20%.
So not only do house plants look pretty, but they are also working to reduce pollutants in your home. Another reason to buy more 😉
In the study, the team tested three common house plants. Corn plant (Dracaena fragrans), Peace Lily (Spathiphyllum wallisii) and fern arum (Zamioculcas zamiifolia).
By placing each plant into a test chamber containing levels of NO2, similar to a house or office located near a busy road, they monitored the plants over the period of an hour.
The results, all three plants were able to remove around half of the NO2 in the chamber over the course of that hour.
Dr Christian Pfrang, who led the study, said: 'The plants we chose were all very different from each other, yet they all showed strikingly similar abilities to remove NO2 from the atmosphere.’
'This is very different from the way indoor plants took up CO2 in our earlier work, which is strongly dependent on environmental factors such as nighttime or daytime, or soil water content.'
Looking at the results in a practical way, putting five plants into a poorly ventilated office with high level of air pollution, you would be able to reduce NO2 levels by around 20%.
So, the more plants the better right?
