Febreze 插電式空氣清新劑，抗臭香精油補充包，節慶綜合香氛，3入補充包

The scent actually holds up for the full 50 days on low, which is way longer than the last brand I tried. The holiday mix is subtle enough to not overpower the room, and one refill lasted me through most of December.

I set mine on low and forgot about it—three weeks later that gingerbread-ish holiday scent is still filling the whole hallway, no fade at all. The 50-day claim actually holds up so far, which is more than I can say for other refills I've tried.

Three months after plugging these in, the holiday mix still greets me at the door every evening—no fading on low, and the tiny bulbs lasted well past the 50-day mark. Honestly, I forgot they were even running until a guest asked what smelled so cozy.
