Cut the hardware cloth to width by cutting a 12-inch strip (8 inches for the width of the filter plus 2 inches on either end) from the entire roll. - 3). Attach the ends of the hardware cloth to the end cap and duct connector piece using duct tape.
- 4). Wrap the hardware cloth around the end cap and duct connector piece, taping every few inches. As you add more layers, the cloth tube will go from flimsy to sturdy. This tube is going to serve as support for the carbon filter.
