Abstract: An air filter secured to the air inlet grid of a hand held hair blow dryer to prohibit the entry of airborne debris. The filter composed of a disc approximately one eighth this is removably fastened to the air inlet grid by means of transverse strips of double coated polyester film applied to the fastening surface of the filter disc. The exposed surface of the transverse strips are coated with a permanent rubber based adhesive which in turn is covered by a release liner to protect the adhesive surface during shipping and handling.

Abstract: A two-level mall of shops is so sited that an approach is made approximately midway between the two levels. Preferably anchor stores are located at both ends of the mall and across from the central entrance. Mall shops are entered by moving up or down a half-level from the entrance to even out the advantage of "main" floor shops. At the ends of the mall, a level change is so encouraged by the layout that shoppers who walk down the length of the mall at one level will likely walk back along the other level. The middle specialty store and mall shops may be multiple level and thus gain advantage of supplemented potential for attracting passing trade.
