Using this dryer duct hose is easy. First, make sure your dryer uses a standard 100mm hose. Then, expand the hose to the 2.5 - metre length you need and connect it to your dryer and the vent kit. When using, ensure there are no kinks in the hose as it may affect the airflow. Also, avoid placing the hose near sharp objects to prevent punctures. For maintenance, check the hose regularly for any signs of wear and tear. If you find any holes or damage, replace the hose promptly. This will help keep your dryer working efficiently and safely.
