Easy Fresh is the world's only air freshener dispenser that uses the fragranced cover of the dispenser as the air freshener refill itself! Now, instead of unlocking a dispenser, unloading the old refill, loading the new refill and replacing the cover, you just take off the old cover/refill and replace it with a fresh one!! Each cover is composed of a unique material containing twice as much fragrance as most other air fresheners which is release over 30 days.
