Great replacement filters!
It wasn't clear to me that the filters fit into the sliding plastic box of the Gard unit as no instructions were included.  Once I figured that out, it fit perfectly.  There are less pleats in this filter than in those accordion filters that that AC people charged me $70 for.  However it's more easily installed (5 minutes?) and far less expensive so I am more likely to replace them in a timely manner which will result in cleaner air over time.  Shipping was much faster than advertised too and the product arrived in pristine condition. All in all, it's an inexpensive and convenient product that will do the job.
