Whether you’re a homebody looking to make your place comfy and cosy, an entertainer out there to wow your guests or yearning to amp up them zen vibes for your morning meditation, you’ll want to consider an essential oil or fragrance diffuser.

While it’ll definitely make your place smell great, a diffuser can do more than just freshen up your room, apartment or house. Typically, diffusers will also help humidify dry air in your home which might be just what you need as we get into the cooler months. While you’re at it, you might want to nab yourself an air purifier to maintain optimal air quality all year round. If you’re like me and and often forget about making time for self-care, now’s also the perfect occasion to consider replenishing your supply of moisturisers and eye creams to keep yourself nourished as winter approaches.

We’ve handpicked ten of the best diffusers you can snag for a deal on Amazon Australia. Most of them offer free delivery and some are even eligible for next-day delivery so your home will smell and feel great in no time. 

Here are our top 10 picks.
