If your dryer blows the lint to the outside through your exhaust
system, then it really doesn't matter how much the screen is catching
and how much is getting past it. The Whirlpool top lint screen dryer,
and the various brands it is sold under, is an excellent machine,
probably the best on the market for performance, durablility, price,
and value. The airflow pattern in this dryer is extremely strong, and
if it is drying in a good amount of time, just ignore the lint issue.

Avoid the "inside" lint screen models made by Whirlpool. These dryers
have a weaker airflow system, and the tubes inside leak lint like a
sieve, causing lint to build up inside the machine and leading to
premature failure for nearby components including the motor, and
increasing the risk of fire exponentially.
