Febreze Bathroom air freshener fights odours from the air and also helps prevent them from lingering on soft surfaces such as towels, bath mats and shower curtains, for up to 50 days. It contains Odourclear odour convertors, which are actually various perfume molecules that easily bind to a broad range of bad odour molecules. Once connected, they react to become a new molecule, forcing them to change their stinky ways. Odour convertors are especially efficient for long-term use, so your bathroom is always guest-ready. With no electricity or batteries required, Febreze Bathroom is convenient and easy to use, available in a variety of scents.
