Oil-based concentrated air fresheners are aromatic products designed to enhance indoor air quality by emitting pleasant fragrances. These fresheners typically come in liquid form and are highly concentrated, requiring only a small amount to release a long-lasting scent. The oil base allows for a gradual and consistent release of the fragrance, creating a pleasant and inviting atmosphere in homes, offices, or other enclosed spaces. Users can customize the intensity of the scent by adjusting the amount of the concentrated oil used, making them a versatile and effective solution for freshening up various environments.
