how many plants do you need in a room to improve air quality?



How many plants are needed to detoxify the discussion in the household? It is clear that the more plants there are, the better and more practicable it is to cleanse the discussion. 

However, experts suggest that you should only place two pots per 9 square meters so that the discussion quality in your home is under the best conditions.

You have probably heard that some people believe that keeping and growing plants at home detoxifies and purifies the air in the house. Perhaps you yourself have a few pots in the corners of your home or workplace under the influence of this theme.


Apart from the feeling of freshness and beauty that plants bring to enclosed spaces, their detoxifying power is still controversial. If you want to know more about this topic, stay with us.

Plants are very important for human life. During photosynthesis, each plant absorbs carbon dioxide and produces new oxygen for us. Plants can also detoxify the air we breathe.

In 1989, NASA published the results of a famous study showing that houseplants can remove carcinogenic natural compounds such as formaldehyde and benzene from the air. 

In this test, NASA analysts were looking for a convincing way to detoxify the space station environment. Subsequent tests revealed that microorganisms in plant pots also play a role in decontaminating indoor environments.


In line with this research, some researchers believe that houseplants are a common and viable method of filtering the discussion. 

The larger and purer the plant, the better results are achieved. Charge Wolverton, a former NASA analyst who studied plants in 1989, says, “The amount of discussion detoxified depends on the size of the plant leaves.


Wolverton believes that expensive research is needed to determine the number of plants required to rid a room of pollutants. However, he advises providing at least two “appropriately sized” plants for every hundred square feet of indoor space.


One of the most effective plants for removing pollutants in the air is the “sword fern,” but sometimes it is difficult to keep this plant indoors,” he says. “Golden Pothos” is usually my first choice because of its popularity and ease of cultivation.


While researching air-purifying plants, we found out that plants purify the air during the process of photosynthesis.

The question now is, what turns carbon into oxygen during photosynthesis? Photosynthesis is the process by which a plant absorbs sunlight and carbon dioxide from the air and converts them into fuel for its growth.

But that’s not all: the most important product of photosynthesis is oxygen!

In addition to removing carbon dioxide and producing oxygen, most plants can also absorb other gasses and chemical toxins such as benzene and formaldehyde from the air.

These pollutants are often found in household items and contribute directly to respiratory problems.

There are houseplants that purify the air in the home and workplace and absorb a large proportion of air pollution.

Plants absorb carbon dioxide and produce oxygen through photosynthesis. This natural process is important to maintain the balance of gases in the air. 

Some scientists believe that plants can absorb certain chemicals from the air and break them down to remove them from the air. Therefore, we can determine whether plants clean the air or not.

Certain plants have been found to be able to assimilate unstable natural compounds (VOCs) emitted by common household items such as cleaning products, paints and furniture. VOCs can contribute to poor indoor air quality and have been linked to various wellbeing issues.


While the NASA study provided initial evidence of the air-purifying properties of plants, subsequent research has produced mixed results. 

Several studies have been conducted to investigate the effectiveness of plants in removing certain pollutants from indoor environments.

A 2009 study found that some houseplants, such as snake plants and golden pothos, can help reduce formaldehyde levels in a laboratory.

 However, the study also found that not many pollutants are removed and that many plants are needed to effectively clean the air.

Other studies have produced mixed results, with some showing little or no effect of plants on air purification.

There is no question that the proximity of plants indoors awakens a feeling of unconditionality and vitality in us. You won’t be able to rely on the detoxification control of indoor plants, but their proximity is certainly not without elegance.
