Having tropical plants in classrooms is believed to improve indoor air quality. These plants act as natural air filters, effectively purifying the air by removing pollutants and releasing oxygen. As a result, students experience increased concentration and overall well-being. Moreover, the presence of plants in the classroom also brings psychological benefits, such as reducing stress levels and enhancing mood, creating a more positive and conducive learning environment.

Incorporating natural elements into buildings is becoming increasingly popular, not just for WELL certification, but also for LEED and other sustainability certifications.
