Rigid ductwork sheet metal ducts are less likely to incur dangerous mold and growths because their surfaces are non porous and smooth.

Flex duct has an inherent flaw based on the very attributes that make it flexible. Flexible ducts are fairly easy to install and will often cost less than the rigid ductwork. This is because they re more versatile and flexible. Flexible ducts are good for air quality because you are not breathing in fiberglass insulation lined ductwork like the fiber air ducts and they are mold and rust resistant unlike galvanized sheet metal ductwork.
