Volatile organic compound pollution is one of the problems of outdoor and indoor environment air quality. Inorder to maintain good air quality, air cleaning technologies are being engaged. One of the recent biological air treatment technology is biofiltration. It is a promising treatment of air from volatile organic compounds (VOCs). Experimental research of droplet biofilter for cleaning VOCs was carried out. Biofilter load of green sphagnum was used with the aim to clean three different concentrations of pollutant toluene. Measurements of biofiltration processes were recorded after 20 and 40 days. The aim of this experimental research is to estimate biofilter efficiency using green sphagnumas a load material.
