I love a nice smelling house, but I don't like the scent to be overpowering. That's why I love Glade PlugIns Scented Oil Vanilla Breeze refills. You will need a previously purchased Glade PlugIns holder that fits into your receptacle. You simply remove the cap, and slip the refill bottle into the holder. The warmth from the plug causes the wonderful fragrance to be dispersed throughout the room. My all-time favorite scent is Vanilla Breeze, and another pleasant one I've tried is Apple Cinnamon. (One scent that WAS overpowering is Hawaiian Breeze.)
Make sure you choose a scent that is to your liking, because it will be noticeable. If you have not experienced the wonderful fragrance, that Glade PlugIns scented oil can provide, then you'll certainly want to try them. My mom has a Glade PlugIns holder with a fan, that circulates the scent even more. I use them in my kitchen, bedroom, bath, and foyer areas. Vanilla Breeze makes your house smell like fresh baked cookies.
It's probably a good idea to check them from time to time, to make sure that the refills have not run out. The only negative I've found with these, is that they are SO very difficult to open. But I'm sure that is to prevent the oil from leaking out, which would be a mess.
So if you're looking for a pleasant, soothing scent for your home, try Glade PlugIns Scented Oil Vanilla Breeze Refills.
