Do plants purify the air around you?
Houseplants aren’t just for decoration but can actually help purify the air in your home. A two-year study conducted by NASA in 1989 compiled a list of air filtering plants which contribute to living a less toxic life. In the study they found that indoor air pollution can be greatly mitigated by the introduction of these plants as they act as a natural air filter. They remove organic air pollutants such as: benzene, formaldehyde and trichloroethylene.
Why is air pollution bad for you?
Poor quality air can contribute to health problems in humans all over the world. These include lung and heart issues, coronary artery disease, emphysema, respiratory infections, stroke and cancer. Children and the elderly are particularly sensitive to air pollution. It can also be dangerous for pregnant women as it can contribute to birth defects. Air pollution is proven to also worsen present conditions such as asthma, chronic obstructive pulmonary disease, cardiovascular disease and diabetes.
The list of plants below were determined to be the top 18 most effective at naturally filtering out indoor air pollutants.
