I first learned about Pura from a friend whose house always smelled like a high-end boutique under every circumstance. Cooking project, water leak … no matter what was going on in her house at the time, I only ever smelled berries. Mercifully, the stand-alone, cylindrical Pura Plus has on/off manual control buttons on the front. If you have high ceilings or any kind of open floor plan, you’ll get better results from the Pura Plus. Perhaps the best feature of the Puras, however, is the brand's extensive library of scents from companies like Anthropologie, Nest, Capri Blue, and more.
