Best Houseplants to Clean Toxic Chemicals from Indoor Air

You may not often think about the quality of the air you breathe indoors but it can be an important factor in a number of health conditions that could be affecting you or your family. The fact is, indoor air is frequently degraded by particulate matter, chemical compounds, and biological contaminants. Even if you clean your home or office frequently, some contaminants may still emanate from common indoor items such as carpets, cleaning agents, furniture made of processed wood, and the material in sofa sets. Some contaminants get into the building from the outside, through open spaces or through the HVAC system. In other words, indoor air contamination is almost inevitable in the modern environment.

The bad news is that the presence of toxic chemicals in the indoor air can lead to Sick Building Syndrome (SBS) or Building-Related Illnesses. SBS refers to instances where occupants of a building experience discomfort or health problems which are linked to the building that they occupy.


What can be Done About it?


The good news is that there’s a simple, natural and cost-effective way to clean common toxic chemicals from the indoor air:  Using houseplants! NASA, the American space agency, was looking for ways to clean indoor air in space stations. After conducting their research, NASA found that certain plants had superior air filtering properties, and they were highly effective in removing contaminants such as Xylene, Benzene, Trichloroethylene, Ammonia, and Formaldehyde from indoor air.


According to NASA, here are 10 houseplants that you can use to clean indoor air:
