摘要：
A biodegradable filter for the removal of various pollutants, contaminants, or harmful substances from the surrounding air, and a method of fabrication. The filter includes 30% by weight of cellulose nanofibers, 30% by weight of activated carbon, and 20% by weight of polyethylene glycol. The cellulose nanofibers and activated carbon are isolated from date palm biomass, making the filter cost-effective and environmentally friendly.
