Our team selected the products on this list based on actual customer reviews. For each category, we carefully selected parameters based on our research and found the diffuser products with the highest review score within those parameters.
With an average rating of 4.6 out of 5 from 875 reviews on Amazon, the best overall diffuser is the ASAKUKI 500ml Essential Oil Diffuser. This product also comes with a one-year warranty as well as a six-month money back guarantee.
This product is packed with additional features to add some Zen to your day and reviewers like how customisable their experience can be. In terms of space, this product covers 25-30m2, which will filter throughout a home from your chosen room.
This diffuser has a decent-sized tank of 500ml, which is ideal if you're looking for something low maintenance since you won't need to re-fill often. Customers also note how easy it is to clean the tank. There's also an automatic shut-off feature for safety if the tank runs out of water, which is ideal if you're using the product to help you drift to sleep.
There are two levels of mist – strong and weak – depending on your preference and the size of the space. There are also 4 timer options: 60, 120 or 180 minutes or continuously on. On weak mist mode, ASAKUKI says the tank will last up to 16 hours and reviews suggest this is accurate. There are also seven different LED colours to personalise the look, and the adjustment features mean you can have the light off if you prefer.
The Natio Ultrasonic Essential Oil Diffuser came out on top as the heat-free Ultrasonic option with an average rating of 4.5 out of 5 from 62 reviewers on the Myer website. This product comes with a one-year warranty.
Customers like this safe and convenient heat-free option. As with our previous pick, this product has an automatic shut-off function, which is great for bedtime. The tank on this product is 100ml and can operate for up to 4 hours when filled. Reviews note that this product is easy to clean.
Customers like that the Nation Ultrasonic Essential Oil Diffuser is fuss-free and user friendly. The overall design of this product is simple and sleek, with ambience coming from the seven lighting modes, which you can have on a transition or choose your favourite.
With an average rating of 4.8 out of 5 from 263 reviews on the Organic Aromas website, the best nebulising diffuser product is the Organic Aromas Raindrop Nebulising Diffuser. This product comes with a one-year parts and service warranty.
This product doesn't use water or heat, and therefore provides a slightly more concentrated scent. This diffuser uses an air pump to naturally disperse the essential oils into millions of micro-particles. No water also means no constant refills, although you do still need to clean out the glass reservoir with a little rubbing alcohol once a week.
The Organic Aromas Raindrop Nebulising Diffuser has an LED rainbow-carousel mood-lighting option to add to the ambience. The product has a shorter operating usage cycle than other types of diffusers. It diffuses for two minutes, then has one minute off and repeats that for two hours before it shuts down. This product also comes with a "volume" switch to control how much oil you diffuse.
This product is made of 100% hardwood and has a hand-blown glass reservoir. You'd be hard pushed to find something more elegant. Many reviews comment that they love the way this product looks and actively display it in their homes.
The best evaporative diffuser available is the dōTERRA Petal Essential Oil Diffuser, which has an average rating of 4.2 out of 5 from 868 global ratings on Amazon. This well-known brand has a good reputation in the wellness industry.
Despite a smaller tank of 150ml, this product has a substantial mist output that can reach an area up to 30m2. As the product is made of three simply designed components, it's easy to remove the lid and refill.
There are multiple diffuser timer settings depending on your preference – every one, two or four hours. This dōTERRA Petal Essential Oil Diffuser also has an automatic shut-off feature for peace of mind.
Optional LED lighting can add to the relaxing effects of this product and customers like the overall aesthetic, which is simple and calming.
With an average rating of 4.6 out of 5 from 14,862 global reviews on Amazon, the best diffuser that can use heat is the URPOWER 500ml Aromatherapy Essential Oil Diffuser, which has 5 different settings. While it doesn't come with a warranty, URPOWER offers 24-hour customer support, which customers have found to be really friendly and useful.
This product has multiple functions. It's an aroma diffuser when using essential oils, a humidifier in air-con rooms or dry winter air and there are also multiple mist nebulising modes. Customers really enjoy the flexibility this product offers.
With a large tank of 500ml, this product can last for up to 10 hours of continuous use or there are timed options of 1 hour, 2 hours or 3 hours. It also comes with an automatic shut-off feature when time is up or the water is out.
There are 14 colour-changing LED lights and 15 different lighting modes to personalise your relaxation time.
The best reed diffuser available at the moment is the NEST Fragrances Reed Diffuser. It has an average rating of 4.4 out of 5 from 3,569 reviews on Amazon.
Although admittedly not as high tech as the other products featured on this list, customers love how simple and calming this reed diffuser is. It comes in 175ml bottles and there are 18 difference scents to choose from.
It has an alcohol-free formula that releases fragrance slowly and can last up to 90 days. To enhance the impact of the scent, it's recommended to rotate the reeds once per week. Customers enjoy how natural all the scents smell, noting that they are long-lasting and not overpowering.
The elegant glass bottle is designed to complement a wide range of home decor, and it can even be repurposed as a small vase when empty.
The best diffuser for large rooms is the KBAYBO Aroma Oil Diffuser, which has an average rating of 4.3 out of 5 from 229 reviews on Amazon. Many customers noted that they prefer this product for the larger rooms in their home. Some noted it is ideal for use in a yoga studio.
This product has a large capacity of 550ml, with 3 generously timed misting modes of 1, 3 and 6 hours. The design has control buttons as well as a remote control that can be used up to six metres away, making it the ideal choice for larger spaces. There are also strength settings depending on your personal preferences.
Despite being so high tech, lots of customers noted how easy it was to set up this product. The sleek design also allows it to be cleaned easily.
The design is compact and elegant, with a faux wood effect, with three looks to choose from to fit your home decor. There are also seven LED colour lighting design options, which add to the overall vibe. Customers note how quiet this product is while in use.
