Lint traps (also known as lint pickers) are devices for removing lint from air currents before they reach the exhaust port. There are different types of lint traps, each with its pros and cons. Some models allow for the user to remove the trapped material by hand, while others require the use of a vacuum cleaner. Lint traps work best if they are cleaned regularly. Most manufacturers recommend cleaning them after every seven to 10 loads of laundry.
