This unique, all-natural plug-in refill is one-of-a-kind in its ability to actually eliminate unpleasant odors, rather than cover them up with fragrance like most other air-fresheners on the market today. Mildly aromatic, and slightly less noticeable to the nose than our other products, this scent combines peppermint, jasmine, and oak moss, to create a fresh, clean, subtle scent. The real star of this show is the all-natural oak moss essential oil. Aside from its subtly warm, woodsy, earthy scent, oak moss has inherent deodorizing properties, and is even used in many natural stick deodorants and sprays sold by personal hygiene retailers. As with all our scents, but especially with the Clean Air Blend, there is a difference between the way the product smells inside the bottle and after it's infused in the air via a warmer.
