The great benefit sustainability of ecotechnology requires an effective policy supported by social perception, an incorporate with the environment impact assessments, cost-benefit analysis and intellectual property. Ecotechnology of phytoremediation is cost effective and ecologically friendly in which plant utilizes its natural abilities to restore environment. It is the use of green plant based systems to remediate contaminated soils, sediments, water or air. Some epiphyte plants, especially those from Spanish moss, Tillandsia useneoides (Bromeliaceae), known as air plants, has been widely used in biomonitoring studies of air pollution in South America countries. The aim of this paper was to review the biological living of T. useneoides and applications for applying our current research in summer monsoon rain and rainy season in Southern Thailand .
