Approximately 40 percent of the lint that is removed from your laundry escapes the lint screen and ends up trapped where it doesn't belong; around the dryer drum, on the motor and in your dryer ducts.

Safety Standards for Dryer Vents

Many people are still using flexible foil, plastic or vinyl venting, which is no longer up to code. Manufacturers recommend using semi-rigid metal for a safer, more efficient dryer vent system.

Bends and turns slow down the flow of dryer exhaust; longer lengths of duct cause moisture to condense, trapping and allowing lint to build up. All of these issues make your dryer work harder; therefore, use more energy.

When sections are joined with screws that protrude to the inside of the dryer duct, they catch lint and cause exhaust leaks. If you have a gas dryer, this could cause carbon monoxide to leak into your home. Leaks in the system also add to the humidity and cause mold and mildew growth. Mold spores are allowed into your home to cause upper respiratory problems for residents.

Manufacturers recommend a professional dryer vent cleaning annually to keep clothes dryers running safely and efficiently. A specialized technician will do a thorough inspection to be sure your system meets current safety codes and is properly installed for optimum air-flow.
