Absolutely love the Air Wick Scented Oil , Snuggle Fresh Linen, Air Freshener! The scent is of fresh laundry, which is one of my most favorite smells ever. The scent can be powerful is enclosed spaces, but put one in an open space and you'll statt to smell fresh linen without overpowering your noses! Each one lasts more than a month for my space, but it can differ depending on the strength and the space. [This review was collected as part of a promotion.]
