Lavender & Chamomile was the first AirWick product I ever purchased, and I'm still using it today! Although it's been many, many years since my first introduction to AirWicks line of products, it's still the ONLY brand I will use! The scents are amazing (and they're always coming up with new ones), and they actually last the full 30 days.I recommend AirWick to anyone looking to freshen up their space, whether it's a sprawling mansion, or a Winnebago, AirWick's got ya covered!
