Modern A/C condensers often feature a built-in receiver-drier tank on the side. This tank houses the A/C condenser filter. This filter consists of a desiccant bag that absorbs moisture and a mesh screen that catches metal shavings. If the filter becomes saturated, moisture will react with the refrigerant, forming harmful acids.
