There are many options for adding pleasant scents to your home with a diffuser. Essential oils, such as lavender, eucalyptus, and peppermint, can be used in combination or on their own to create a soothing atmosphere. You can also use natural fragrances like dried flowers or citrus peels. If you want something more concentrated, fragrance oils are a good option. Pre-made scent blends designed for diffusers are also available for easy and hassle-free use.
