Plants are indispensable to human life. Through photosynthesis, they convert the carbon dioxide we exhale into fresh oxygen, and they can also remove toxins from the air we breathe. Who wouldn’t want a couple of good ol’ plants in their home?

But exactly how many plants are needed to purify air in a given space?

People are familiar with the benefits of having living plants in their homes and offices. Not only are they aesthetically pleasing, but they also absorb and filter toxins from the atmosphere, increasing air quality and our well-being.

The amount of carbon dioxide required to increase the air’s oxygen concentration in a room is approximately the same amount as is produced by a human being in an hour.

This is why a houseplant in a room can easily absorb carbon dioxide, making the air quality more favorable. Indoor plants also filter out various toxins from the air and many even remove certain airborne chemical compounds.

Indoor plants are an inexpensive way to effectively improve air quality in most offices and homes. However, we should keep in mind that different plants have different needs. Some are tolerant of low light conditions, while others need bright sunlight. Outdoor plants are affected by pollution, while indoor plants placed near a drafty window may dry out quickly. So, it’s important to select the right plant for our space.

If we have a small or medium-sized house, a single plant will be enough to keep the air clean. For each additional person in the house, we’d need about one more plant.

In offices, depending on the amount of traffic the room receives and its size, we need about six to eight plants. A larger office space can hold more plants.

For public areas such as airports or stations, a few dozen plants may be required.
