Febreze 插電式空氣清新劑，除臭香精油補充包，莓果與黑莓香，6入補充包（2包裝，每包3入）

I've had these plugged in for three weeks now and the berry scent is still going strong, unlike other refills that fade after a few days. The 3-pack means I don't have to think about replacing them for a while.

I was skeptical about the "fade defy" claim since most refills smell strong for three days then nothing, but this one actually kept the berry scent noticeable for the full stretch. Two packs of three refills means I'm set for months, which softens the cost per refill.

I put one of these in the hallway plug and the berry scent is still just as strong three weeks in, unlike the last refills I had that died after a few days. Getting six refills in one pack means I won't be swapping them out constantly.
