Query: Not the size in product description.

I ordered three filters thinking I was ordering Hunter Brand Filters. The title is misleading because it reads "Hunter 30901 Replacement Pre-Filter for HEPAtech Quiet Flo Air Purfiers." These are filters in unmarked Ziploc Bags. The size I received was 16" x 49". I can't rate the product because I haven't used it but I am not happy I was duped into thinking I was purchasing the Hunter Brand Pre-Filter.
