Dryer vents that connect from your dryer out the house are meant to filter lint out from your dryer. Just cleaning the lint filter from your machine is not the only place that lint builds up.

It is Recommended that you get your dryer vent cleaned every 1-3 years depending on the amount of use on your dryer unit.

The combination of high heat, a small chamber, and combustible materials can be lethal. “Failure to clean” was cited in 33% of dryer fires, as cited by the National Fire Protection Association.
