There are so many air fresheners on the market.  It is hit or miss.  Well, the Renuzit Long Last Adjustable Air Freshener is a hit with me.  Twist to release the desired amount of scent; my favorites are raspberry and tropical.  It sits on a shelf, table or counter.  I actually set them on clothes closet shelves to keep the air from becoming stale.  This product seems to last much longer than other air fresheners I have tried.
