Keep The Air Fresh With Charcoal Filter: The filter core is made of 1050+ activated charcoal imported from Australia to bring 100%-fresh air and eliminate odors, harsh tastes, and particles. The double-sided galvanized steel mesh provides 53% of the open area for airflow to pass through so that the odor absorption and elimination process can be carried out thoroughly. (The carbon filter was covered by a prefilter cloth; do not remove it when using.)
