Do Houseplants Really Help Improve Air Quality? Exploring the Science Behind It

Houseplants can potentially help improve air quality by removing some pollutants from the air. They do this through a process called phytoremediation, in which they absorb certain pollutants from the air through tiny pores on their leaves. The pollutants are then either stored within the plant or broken down and used as food.

However, it is important to note that the ability of a houseplant to remove pollutants from the air can vary greatly depending on the plant species and the specific pollutant in question. Some plants are better at removing certain pollutants than others, and some plants are more effective at removing pollutants when they are grown in certain conditions (e.g., when they are larger or when they are grown in soil that has been treated with certain amendments).

In general, the effectiveness of houseplants at improving air quality is limited. While they can potentially remove some pollutants from the air, they are not a replacement for proper ventilation and other methods of addressing indoor air pollution.

For decades, we have been told that houseplants can improve air quality – but is there any truth to this claim? According to a study conducted by NASA in 1989, certain common plants may be capable of reducing indoor pollution levels by removing VOCs like benzene and formaldehyde. But the EPA found that due to its limited sample size, applying these results on real-life settings would require an absurdly high number of 680 potted plants for a 1500sqft home! Nonetheless, it’s still worth considering how greening up your living space might make for cleaner air inside your abode.

Besides their aesthetic appeal, having potted friends around us has been linked to improving mood and even aiding in deeper sleep!
