We've had automatic washers since the 1950s. Some have had filters and some
have not. For those that do, it's a good practice to clean he filter after each
load. You may find some lint, hair, etc., or practically none at all. It's
just good practice.
Having said that, assuming you have a clothes dryer, it will always have a lint
filter and will catch anything that the washer does not.
