Febreze Plug-in Luchtverfrisser, Gain Original Geur, Geurbestrijder voor Sterke Geuren, 1 Verdamper + 4 Navulverpakkingen

I've had this plugged in near the litter box for two weeks now, and the Gain scent actually masks the funk instead of just layering over it. The warmer's low setting is enough for our hallway, and I'm only a third of the way through the first refill already.

The warmer is nice and compact, so it doesn't stick out awkwardly in the hallway outlet. Set it to the lowest level and the Gain scent still cuts through cooking smells for weeks, which is exactly what I needed.

The oil refills are lasting way longer than the cheap ones I used before, and the warmer itself is pretty discreet. Even after my dog’s accident in the hallway, the Gain scent actually covers it up instead of just mixing with it.
