Scent: The choices here are endless. You'll find single scent notes, like lemon or lavender, but most air fresheners now also offer more complex scent combinations with woodsy, floral or spicy notes for a more upscale and appealing experience. Many are made with essential oils, though synthetic fragrances are just as effective. If you prefer continuous yet understated freshening, look for a product that allows you to adjust the level of scent it emits. Unfortunately, there isn't an easy answer, as all air fresheners have their own set of pros and cons, depending on your target area and personal preferences. You could follow your cleaning schedule to a T, but if your home doesn't smell clean, it won't feel clean. You know what it's like to leave and come home only to smell the garlic you sautéed at dinner or your pet's dander. And if you smell it, so will your guests. Thankfully, a good air freshener is an easy and cheap way to infuse your home with a long-lasting scent as well as eliminate — not just cover up! — odors without being too overpowering.
