According to the US Fire Administration more than 40 clothes dryers catch fire in the U.S. every day. Annually between 2002 and 2004 clothes dryers were involved in an estimated 15,600 structure fires, fifteen deaths, 400 injuries, and US$99 million in direct property damage. One of the main culprits in dryer-related fires is lint. As it builds up it restricts airflow, not only creating a fire hazard, but also wasting energy. The LintAlert combats this needless destruction and waste of electricity by alerting homeowners to any blockage or restriction in the vent system of the dryer.
