Based on user reports and typical usage patterns with a Wallflowers plug set to a medium intensity, a single refill is generally expected to last between 3 to 5 weeks. This duration can fluctuate based on ambient room temperature, air circulation, and the specific fragrance oil concentration, with warmer, more circulated environments potentially reducing longevity slightly.

For average-sized rooms, such as bedrooms or living areas approximately 100-200 sq ft, the Wallflowers refills provide a consistent, gentle scent. For larger open-plan spaces exceeding 300 sq ft, users often find that using two plugs or placing them strategically can enhance the scent diffusion, ensuring an even distribution rather than a concentrated burst.

Yes, the design of the Wallflowers fragrance refills is standardized to ensure compatibility across all Bath & Body Works Wallflowers plugs, including rotating base models. The standard threaded neck on each 1.6 fl oz refill unit is engineered to fit securely into any of their proprietary plug mechanisms, maintaining a stable connection for optimal oil diffusion.
