The present paper describes an experimental test to identify the possible influences that the presence of plant species may have on the environmental quality of indoor spaces. For this purpose, a selection of houseplants with high air purification capacities was made based on existing literature (Sansevieria, Poto, Spathiphyllum, Ficus Benjamina, Kentia and Areca). Two adjacent rooms within an experimental building were used as test cells. The two rooms have similar characteristics. One room was occupied with the plants and the other was left empty.
