Sorry to admit it,...I'm a clean-freak... who smokes. Bad combination! No matter how much you clean, if it doesn't smell nice, no one notices anything but the smoke odor. Then along came Lavender & Chamomile oil to the rescue! Since I started using this product (many years ago) almost everyone entering my house remarks on "how nice it always smells". Although I regularly try other scents, this is by far my favorite. I love to get the three pack & rotate the timing on putting them in, so that when one is getting weaker, I always have a fresh one. Thanks Air Wick. I love, love, LOVE this product!
