While running through the dryer, your clothes shed a lot of dust. Nearly 1/2 of the dust from each load gets by the filter. Over time, this dust builds up into Lint. Once there's lint in the duct, it's easier for more debris to get caught and clog the vent. A yearly or bi-yearly cleaning is recommended depending on the vent length and location. Also, the amount of times a day the machine is used. We help customers avoid hassles such as dryer malfunction and most important, house fires.
