Product review (4 stars): Fits older Maytag dryers
If you've got one of those old and fairly bullet proof Maytag dryers, and the nylon screen has seen better days as ours had, you need a new one of these to keep as much lint as possible out of your vent system, thereby reducing a fire hazard.  Our original one, now some 34 years old, developed a tear.  This fit perfectly.  Seems most older Maytags take this filter, but check your model number against the list, or at other sites that provide Maytag parts.  On ours, the model number was on a stamped aluminum plate behind the dryer's door.  Price was perhaps a tad high for what it is, but not unreasonably so.  And was competitive.
