Adaptil DAP Diffuser Refill is a 48ml replacement vial for the Adaptil plug-in diffuser, providing up to 30 days of continuous dog appeasing pheromone release. For owners already running an Adaptil diffuser who need to maintain monthly coverage.

Each refill lasts approximately 30 days and covers up to 70 square metres. The vial slots into the existing Adaptil diffuser unit with no new hardware needed. The DAP pheromone is odourless to humans and works continuously in the background. Replace monthly for uninterrupted calming support — gaps in coverage allow stress behaviours to re-establish.

Consistent monthly refills are what make pheromone diffusers effective. Keeping a spare on hand ensures coverage doesn't lapse during high-stress periods like fireworks season, thunderstorms, or household changes.
