Inventor Harold Leffelman of Binks Filter Systems, Grantsburg, WI, has designed a new filtering system for room air conditioners that he says will save energy, reduce service calls, and prolong the life of the unit. It consists of two rack holders installed on both sides of the condenser air inlet vanes or on the front of models with that system. Manufacturers and filter companies interested in the new design can contact Leffelman at 715-463-2283.
