Product review (5 stars): Saved us over $30
My hubby usually has this filter replaced with our semi annual air / heat inspection.  They charge us for the service call which also includes their much needed expertise of course.  But they charge us $45 for the replacement filter!  I ordered this one, and he put it in himself before the inspection and it saved us a lot of money in their mark-up.  Neither one of us are handy, so if we can replace it, anyone can.  This was a good value for us.
