The LG dryer lint screen works like When clothing tumbles around in the dryer, the agitation and high heat cause clothing, towels, and linens to shed some of their fibers. The lint screen catches many of these fibres to prevent obstructing the dryer vent hose. It protects the more delicate lint filter in your dryer so that it doesn’t get damaged and lint can’t mix in with your clothes. This product was made of plastic.
