Drastically decreases the risk of fire.
Almost all dryer fires are caused by link build up. There are up to 16 deaths per year, and over $100,000,000 in damages from lint build up in dryer vents. Lint is highly combustible and when dryers cannot expel hot air the result can be a fire. Most dryer damage and fires can be prevented with proper dryer vent cleaning.

Doing laundry just got faster. With a good flow of air through the vents the clothes will take less time to dry.

Improper air flow damages the dryer and decreases the dryers life span.
