Product review (5 stars): Great price, easy replacement
My original had turned into a science project and desperately needed replacement.  This dropped right into place and seemed identical to the original.

Also recommend folks try searching online for replacement air filters.  I have an odd sized air filter (16x24) that was impossible to find at the home improvement stores.  After digging online I was able to find a case of 12 very high quality generic packaged filters at a very low cost per filter. The element seems suspiciously similar to some of the so called high end filters I see in the stores. I now have no problem changing my filter very often since they are not expensive.
