Choosing the right Kanberra Gel size depends on the area you want to keep fresh and odor-free. For smaller spaces, like bathrooms, closets, or vehicles, the 2 oz jar is ideal. For medium-sized rooms, such as bedrooms or offices, a 4 oz jar provides broader coverage. In larger areas like kitchens, living rooms, or boats, the 8 oz jar works best to ensure consistent odor control. For expansive spaces or highly trafficked areas, the 16 oz jar offers maximum protection and longer-lasting freshness. Each jar size is designed to release natural air purifying agents effectively, helping you select the perfect size for your needs.
