"I'm getting tired of using plug-ins because my cat keeps knocking them down and plus one leaded on my wall and it took the paint off. This right here is a huge game changer, I cut it in half and put it in two of my vents in my living room and it SMELLS so good. I want to see if they have holiday scents nows!"

"Okay. So one day, the loud box in the ceiling (they call it “central air,” I call it “The Wind Beast”) turned on like usual. I braced myself for the whoosh. But this time... WHOA. The air didn’t smell like socks, meatloaf leftovers, or that suspicious plastic bag in the trash. No. It smelled like—get this—a magical breeze from a beach where squirrels bring you cocktails. I don’t know what a Pink Sand is. I’ve never seen sand that wasn’t stuck in my paws. But if Pink Sands is what’s coming out of the vents now? I'm obsessed. I follow the air around the house like it’s the tail I haven’t caught yet. It’s in the hallway. It’s in the bedroom. It’s in my nap zone. Every room now smells like what I imagine my human thinks Fiji smells like, except without the inconvenience of a bath. Even the mailman sniffed the air and paused before ringing the doorbell. Respect. I’ve stopped rolling in the laundry pile because now the floor smells better than the clothes. My only complaint? It doesn’t smell like bacon. But I’ll let that slide. Anyway, big thanks to my human for turning our home into a beachy paradise. 5 paws out of 5. Now please excuse me while I go lay under the vent and pretend, I’m in a doggie day spa."

"I live in apartments and my neighbors are jerks and like to smoke the devils lettuce. These bad boys make the apartment smell fresh and last for a long time. Easy to install. Just hang it and if the filter is vertical when the AC kicks on it sucks it into place. Great price, refreshing scent, performs above expectations and my apartment no longer smells like a college dorm."
