Easy Fresh provides consistent freshness for 30 days. Cover contains two to three times more fragrance than gels or metered aerosols. Motor-driven fan moves the air freshener further than a typical passive system. Easy Fresh is powered by a smart chip that controls the fan consistently, turning it sparingly the first week & gradually turning more frequently until the fourth week when it runs constantly. This technology ensures your space smells fresh & clean from day one to day 30. Maintenance is easy with LED / audible reminders & a push-button cover for quick removal & replacement. Easy Fresh refills are part of Fresh Product's closed-loop recycling program & are 100 percent recyclable.
