Scented oil refill features a Morning and Dew scent to enhance rooms with the fresh, dewy scent of a rainy day. Unique odor converters transform the structure of malodors to prevent your nose from detecting lingering smells in the air. Long-lasting scent cleans away stinks for 1,200 hours on the low setting. Scented oil refill is compatible with both the classic and newly redesigned Febreze oil warmers (sold separately).
