Ambi Pur 3-Volution Air Freshener Refill Cotton Fresh Lasting 90 Days 20ml Cotton Fresh fragrance is inspired by the freshness of pure white cotton. Let a sense of calm envelop you as this clean and gentle scent fills the air. With normal plugs, we get used to scents quickly, which means we eventually stop noticing the scent around us. Febreze 3Volution air fresheners solve this problem by continuously and automatically alternating every 45 minutes between 3 complementary, high-quality scents, for a continuous fresh experience. Use the Febreze 3Volution refills only with Febreze 3Volution devices, sold separately, to fill your home with air freshness and fragrance that you will keep noticing day after day, week after week. And for instant freshness, try the full range of Febreze products with the odour clear technology, such as Febreze Fabric Refresher, Air and Car Freshener. Directions: Always keep refill upright. Remove the 3 caps from the refill. Never separate the single bottles from the coloured common holder. Do not mix fragrance bottles within refills. Unplug before inserting the refill. Insert the refill until it clicks into place. Avoid damaging the wicks. Plug the diffuser into the socket with bottles at the bottom. Leave 50cm clear above to ensure good evaporation. When plugged in, the diffuser chooses randomly from which fragrance to start the cycle. A red light will illuminate, highlighting which fragrance is evaporating. Every 45 min a different fragrance will be diffused into the air. Adjust overall fragrance strength if required. Replace refill when the bottle is empty, although the light will still illuminate. Package Includes: Ambi Pur 3-Volution Air Freshener Refill Cotton Fresh, 20ml
