Plants are capable of converting carbon dioxide into oxygen, there is no doubt about that – but how many houseplants do you need to increase the oxygen in the air?
A person consumes about 550 liters of oxygen per day. How much oxygen a plant produces is influenced by various factors, including the rate at which it grows and the light intensity of its leaves.
It is estimated that 22 liters of oxygen will be released while the weight of the plant increases by 150 grams – and in order to receive 550 liters per day, the increase should be 3.75 kilograms per day.
Such a growth of green mass can be imagined in the park, but definitely not at home – you simply do not have enough space for plants.
One can also come across statements that the quality of oxygen is higher in green spaces – however, this formulation is meaningless.
Oxygen is simply a two-atom molecule that cannot be of low or high quality. In addition, plants are not only engaged in photosynthesis, but also breathe – that is, they absorb oxygen and produce carbon dioxide.
In general, the amount of oxygen that plants add to the room atmosphere is negligible compared to the respiratory needs of a person – as the author of the Garden Myths blog writes, “if you want to really increase the oxygen level in an apartment, get rid of your partner and children.”
