The 3 Best Essential Oil Diffusers (and One to Avoid)

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. I have two cats and a multi-sports-playing tween—I knew I needed this. Now, about 14 months into my Pura journey, I have some thoughts.

While most of my time has been with the now discontinued Pura 3, I have also since used the Pura 4 and new large-room Pura Plus, all of which have dual bays for two of Pura’s proprietary oil cartridges. The Pura 3 and 4 both plug into an outlet and can only be controlled through the accompanying app (or Alexa or Google Home). This is convenient for setting schedules and timers, switching fragrances, and changing the color of the optional night-light, but there have also been numerous occasions where I’ve wanted to stop or start or change a schedule but have been unable to because I forgot my password or the diffuser couldn’t connect to Wi-Fi. In the moment, it was infuriating. Mercifully, the stand-alone, cylindrical Pura Plus has manual control buttons on the front. The smaller Pura 4 really is best for enclosed spaces, like a long entryway or a bedroom (note that both only work with 2.4-Ghz Wi-Fi). If you have high ceilings or any kind of open floor plan, you’ll get better results from the Pura Plus. Just note that, unlike the silent Pura 4, the Plus emits an audible whooshing sound that’s actually quite loud—32 decibels, as loud as a fan on low.

Another disappointing feature is the extremely varied quality among cartridge brands. I’ve experienced undetectable scents, chip stickers that arrive detached or register the wrong fragrance (the diffusers automatically scan the chips to show the fragrances in the app), and vial tops so stuck on they required pliers. Given that the cartridges run $11 to $17 for 0.33 ounces, I’m of the opinion this shouldn’t be happening. That said, Pura is known for its clean, upscale oils that are safe for pets and families, and on this it delivers. There’s an extensive selection of seasonal and year-round cartridges from companies like Nest, Anthropologie, and Capri Blue, and I’ve loved all but maybe one of the dozen or so I’ve tried. Because of the small size and price of the cartridges, Pura might not be the best choice if you want to smell diffuser all day, every day, as you’ll end up spending a small fortune. However, if you love unique luxury scents and only need them occasionally and/or on demand, Pura is the way to go. —Kat Merck
