Febreze Plug in Air Fresheners, Heavy Duty Crisp Clean, Odor Eliminator for Strong Odors, Scented Oil Refill (2 Count)

The Crisp Clean scent actually cut through the lingering cooking smell in my kitchen within a day, which surprised me since I've tried weaker plug-ins before. The two refills lasting a good while is a nice bonus too.

Swapped these into the plug in the bathroom and the musty smell after showers is gone within a day. The crisp clean scent is strong at first so I keep it on the low setting, but it fades into the background nicely. Two refills in the pack was a good deal for trying it out.

These actually cut through the litter box smell in my laundry room, which nothing else has managed. Two refills in the pack lasted me about six weeks on the low setting.
