Powerful enough to freshen even your largest spaces, Easy Fresh is the worlds only air freshener dispenser that uses the fragranced cover of the dispenser as the air freshener refill itself! Now you can save yourself time and energy with a product that makes replacement easy. The Easy Fresh fragranced cover is composed of a unique material containing 2-3 times more fragrance than gels or metered aerosols. The motor-driven fan moves fragrance further than a typical passive system, thus freshening larger areas. The smart system behind the Easy Fresh releases approximately the same amount of air freshener daily over 30 days by turning the fan sparingly in week 1, and gradually turning it more frequently until week 4 when the fan runs constantly. The smart dispenser comes with a light that alerts you to change your cover after 30 days, and begins counting down another 30 days once you change the cover!
