Between your pets and last night's dinner, your home can be full of lingering smells that don't always blend nicely. Our brēthe® Air Revitalizer uses water and 100% natural citrus air revitalizers to wash air of its odors — even cigarette smoke. brēthe's blue LED lights cast a pleasant glow while it goes to work, covering up to 500 square feet. It's environmentally safe, making it preferable to sprays and other cleaning chemicals. Includes three 30 mL bottles of Lemon, Lime, and Orange air revitalizers.
