Product review (1 stars): Smaller Than Previous Filter
Until the cold/dry weather gets here I won't be able to make sure this unit functions properly.  This filter is smaller than the filters I've ordered in the past 5 years from another supplier by over 1".  This concerns me as it may not work properly.

I will say that the vendor has offered to accept a return on the filter, however, at my expense.  I will probably go back to ordering from my previous supplier next year.
