Indoor activities involving cooking and warming, outdoor sources, smoking, and candle and in-cense burning may introduce a massive portion of polycyclic fragrant hydrocarbons. These are well known for their mutagenicity and carcinogenicity and are omnipresent in urban situations as a result of the combustion of fuel. Due to small particle size, penetration has been suspected to be one major source of indoor polycyclic aromatic hydrocarbons. In the current study, the manufacturing of three types of filters (electrostatic charge-based, pomegranate peel biochar-based, and birds’ feathers-based) was carried out. Their efficiency was tested to remove molecules bounded PAHs and also other geno-toxic compounds associated with these particles. The electrostatic filter was more efficient (27.42%) than pomegranate peel-based and birds’ feathers-based filters (13.86% and 8.32%, respectively). The carcinogenetic effects of PAHs emitted from outdoor and indoor pollutants can be reduced using these kinds of filters.
