Air conditioning filters. Comparison of two filters from an air conditioner. The white filter has never been used, and the dark one is after use in a working air conditioner. Air conditioners pass air through filters to clean it before cooling. This filters out pollutants and dust. Air conditioning filters need to be regularly replaced.
