In the last 4th decade, researchers discover that indoor plants have abilities to reduce indoor air pollution. Generally, plants, carbon dioxide (CO2), light, and temperature involve in the photosynthesis process. … All the indoor plants absorbed more CO2, when the light intensity is increased.

How much do plants reduce CO2 in a room?

Plants can also help manage carbon dioxide levels. Dr Torpy’s research group analysed the effect of indoor plants on air quality in workplaces and found that in offices with plants, CO2 levels reduced by about 10 per cent in an air-conditioned building and 25 per cent in a building without air-conditioning.

What plants are best for removing CO2?

Dracaena plants have shown to be one of the most effective air filters. The plant removes formaldehyde, benzene, trichloroethylene and carbon dioxide – all of which are linked to health problems. Dracaena plants also tend to increase the humidity of a room which in turn helps to control respiratory distresses.
