Abstract

A filter system for protecting a heat exchange coil from corrosive constituents carried by an air stream which is passed through the heat exchange coil includes a flexible filter for removing the corrosive constituents from the air stream prior to its engaging with the coil. A net like spacer is located between the coil and the flexible filter for supporting the flexible filter in a predetermined spaced relationship with the heat exchange coil.
