Do Houseplants Clean the Air – Unbelievable!

Houseplants keep you happy and even productive at times in your house. Houseplants lighten up your home and bring out the beauty in fascinating ways. An extensive range of plants can be kept as houseplants to fill your house with green and glossy foliage.

Houseplants are also known to clean the air that you breathe as they photosynthesize to keep a check on the carbon dioxide and other gases in the atmosphere. In exchange, they provide us with oxygen, which is essential for our breathing.

Do Houseplants Clean the Air?

Some houseplants clean the air while other houseplants don’t. NASA’s scientific experiment has proved that certain houseplants help maintain the purity of the indoor air. They help to purify the volatile organic compounds (VOC) and other gases like carbon dioxide from the air and provide us with oxygen and clean air to breathe. The roots and the leaves inhale these gases and neutralize them effectively


How Can Houseplants Improve the Air Quality?

Plant function is essential for not only keeping themselves alive but also for humans. Plants carry out photosynthesis, which helps them to maintain the level of gases within the environment.

Humans and plants exhale opposite gases. Humans provide carbon dioxide while plants take in carbon dioxide and give oxygen to humans to breathe.

Most houseplant species belong to the tropical rainforests and adapt to low light levels in our houses.



Phytoremediation is the process that helps the plants to flush out the chemicals, and air toxins present around them.

This is one of the reasons how indoor plants benefit our health. This process also helps to decrease the level of harmful toxins like formaldehyde and benzene.

Plants absorb the toxins and gases (carbon dioxide) and allow a clean and toxin-free environment to breathe.


Process of Transpiration and Stomata

They intake the toxic gases and the vapors into their leaves and roots through the process of transpiration. The openings that absorb these vapors are called stomata.

Even NASA’s study claims that the presence of molds and bacteria reduces by 50-60% with houseplants. They also help to reduce stress and boost your mood.


What Types of Houseplants Purify the Air?

Many houseplants clean the air and maintain a toxic-free environment. But for them to function perfectly, you need to maintain proper plant care.

Rubber Plant (Ficus Elastica)

This natural humidifier is not only easy to care for but also helps purify the air. The large foliage performs the cleansing.

The foliage inhales the toxic pollutants and breaks them into harmless gases. Rubber Plant is also useful in destroying bacteria and mold present in the air.

Xylene, benzene, formaldehyde, and trichloroethylene are the main toxins removed by Rubber Plants.


Frequently Asked Questions

How many houseplants are needed to clean the air, according to NASA’s Clean Air Study?

According to the NASA research studies, almost 15-18 plants purify the air for 1800 square feet area. That means that there should be about one plant per 100 square feet of floor space.


Are purifying plants better than the air-purifiers?

Although plants have less power than air-purifiers, they are natural, in-expensive, and improve our mood and productivity.
