AromaAllure Essential Oil Diffuser

Do you want to avoid consistently refilling a diffuser's water tank? Then opt for a waterless model, such as this one from AromaAllure. This oil diffuser uses a fan to disperse the scent from your favorite essential oils—no heat or water necessary. In fact, you don't even need a plug, so this diffuser can easily travel with you or sit on a surface without an available outlet.

This diffuser needs two AAA batteries, or you can use it with the included USB power cord. Simply add a few drops of your favorite oils to the microfiber pads, replace the wooden cap, and switch on the diffuser. This option comes with three microfiber pads for three distinct fragrance blends, but if you like to switch it up often, you can buy separate pads as well.

Ultrasonic Aroma Diffuser

One of the great things about essential oil diffusers is that they're usually quite affordable, and we love the appearance of this budget-friendly Ultrasonic Aroma Diffuser from Better Homes & Gardens. This model has a 100-milliliter capacity that lasts for up to four hours, and it's surprisingly stylish with its Moroccan scroll-inspired exterior.

This aroma diffuser adds humidity to the air with its cool mist, and it features a color-changing LED light for ambiance. Our tester liked the versatile light option and automatic shut-off feature. Plus, you can't beat the affordable price.

"While the instructions suggest using four drops of essential oil, we quickly found that was far too much scent for our medium-sized room. After opening the windows and letting everything air out, we started again with just a single drop."—Julie Hershman, Product Tester

jasmine-oil-diffuser

This battery-powered aroma diffuser makes a chic addition to any room. The Stadler Form Jasmine Aroma Diffuser boasts both continuous and intermittent settings, and it can run for up to 24 hours in interval mode. It's small and lightweight, and this product comes in several pretty colors.

The tank on this diffuser is 100 milliliters, and you can charge it via a USB cord. It's a great option to freshen your bedroom or office, and the design is much sleeker than other oil diffusers.

vitruvi stone diffuser

If you're looking for a stylish, reliable diffuser and don't mind spending a little extra, the Vitruvi Stone Diffuser is definitely the way to go. This beautiful model is made from porcelain, and it can run for four hours on continuous or eight hours on intermittent mode.

"Though this diffuser is rated for large 500-square-foot spaces and the instructions recommend using 20 to 25 drops of essential oil, we found that was way too much. Two to three drops were all it took to disperse a subtle, relaxing scent."—Julie Hershman, Product Tester

exqline-diffuser

Small essential oil diffusers are useful in one room, but if you have an open floor plan or a large space, you might want a model like the Exqline Aroma Essential Oil Diffuser. Not only is this product powerful enough to diffuse scents over 450 square feet, but it also has a large 1500-milliliter water capacity that delivers long-lasting operation.

InnoGear Car Diffuser

If you've ever wished you could make your car smell a little better with the help of essential oils, you're in luck. This portable essential oil diffuser from InnoGear is designed especially for cars—it fits right into your cup holder and can be powered via a USB cord plugged into your car's auxiliary power outlet (you will need a compatible adapter, but they're inexpensive).

This oil diffuser comes in white and black, and its small 50-milliliter water tank operates in continuous or intermittent mode. It lights up in different, ambient colors, and the unit will automatically shut off when it runs out of water. Plus, it's quite affordable—a small price to pay for a better-smelling vehicle.

Final Verdict

For an oil diffuser that's easy to use and affordable, we love the InnoGear Aromatherapy Essential Oil Diffuser. This model is powerful with a 100-milliliter capacity, and it has seven light colors. Another budget-friendly option we recommend is the Better Homes & Gardens Ultrasonic Aroma Diffuser. It has a stylish Moroccan scroll-inspired exterior, versatile light option, and automatic shut-off feature.

Type

There are two main types of oil diffusers: ultrasonic and nebulizing. Both versions create a fine mist, but they work a bit differently. Ultrasonic models—the cheaper option—create vibrations that break the essential oils down and distribute the individual molecules into the air. Nebulizing models distribute more potent, undiluted essential oils into the room by using pressurized air.

Capacity and time

Ultrasonic models require a mixture of water and essential oils, which allows them to run for longer—approximately 30 to 60 minutes at a time. Since nebulizing models use only essential oil, they should be run for shorter periods (about 10 minutes at a time).

Cleaning

Both types of models benefit from regular cleaning, but ultrasonic essential oil diffusers are more difficult to clean since they use both water and essential oils. Water makes the machine more susceptible to mold, and tap water can leave calcium deposits inside the machine.
