The 4 Best Essential Oil Diffusers of 2024: My Testing and Review
If you’re like me and love filling your home with a signature scent, you’ll appreciate using one of the best essential oil diffusers to spread consistent, natural fragrance throughout your space. I’ve found that diffusers are a safer, more natural alternative to candles since they don’t involve an open flame.
Diffusers work by holding essential or fragrance oils and dispersing them into the air. There are two main types: ultrasonic and nebulizing. Ultrasonic diffusers use evaporating water to spread fragrance into the air, while nebulizing diffusers create an internal vacuum that lifts oils without adding humidity. The main difference is that ultrasonic models produce a diluted fragrance that lasts longer, while nebulizing diffusers deliver a concentrated scent.
To find the best essential oil diffusers, I tested nine options over two months, considering ease of use, performance, and cleaning. I also spoke with Amanda Lattin, dean of aromatherapy at the American College of Healthcare Science, to ensure my choices were well-informed. My favorite pick is the Asakuki 500 mL Premium Essential Oil Diffuser, thanks to its large water tank, adjustable mist settings, and user-friendly design. If you’re looking for something smarter, the Pura 4 Smart Fragrance Diffuser lets you control fragrance intensity via an app and pairs with popular candle brands.
My Picks for the Best Essential Oil Diffusers
1. Best Overall: Asakuki 500 mL Premium Essential Oil Diffuser
If you are in a rush and want the TDLR version, this Asakui oil diffuser is what I recommend. You can check it out on Amazon here. (Quick disclaimer: As an Amazon Associate, I earn from qualifying purchases.)
What I loved most about the Asakuki diffuser is how simple and versatile it is. Its remote control made it easy to set timers, adjust the LED lighting, and choose the mist’s intensity—all without getting up from my seat.
This diffuser’s 500 mL tank meant I didn’t have to refill it often; during one test, it ran for a full 16 hours before the reservoir needed topping up. It also worked beautifully in rooms of all sizes. My 180-square-foot bedroom and 220-square-foot living room (with 25-foot-high ceilings) both smelled amazing without the scent being overpowering.
The only minor drawback is its 6.6-inch diameter, which takes up more space compared to slimmer models. I recommend placing it on a wide surface like a side table or counter.
2. Best Compact: Urpower 2nd Generation Essential Oil Diffuser
If you’re on a budget or just need a simple diffuser for a smaller space, the Urpower 2nd Generation Essential Oil Diffuser is an excellent choice. Despite its smaller 100 mL water capacity, it surprised me with a six-hour runtime—longer than some larger models I tested.
This compact diffuser features seven LED mood lights and automatically shuts off when it runs dry. Cleaning it was straightforward; I just used water and white vinegar. If you don’t need fancy features, this diffuser is perfect for small rooms or offices.
3. Best Smart: Pura 4 Smart Fragrance Diffuser
The Pura 4 Smart Fragrance Diffuser is a game-changer. It’s completely waterless and pairs with an app that lets you control fragrance intensity, set schedules, and even monitor how much oil is left in the vial. Setup was a breeze; I had it connected to WiFi in under a minute.
I loved the variety of fragrances available through Pura’s partnerships with brands like Capri Blue and Nest NY. My favorites were Capri Blue Volcano and Otherland Cardamom Milk. With adjustable intensity settings, this diffuser filled my open floor plan and vaulted ceilings effortlessly. It’s also a hit with guests, as I can remotely turn it on to create a welcoming atmosphere before they arrive.
4. Best Waterless: Organic Aromas Raindrop Nebulizing Diffuser
Using the Organic Aromas Raindrop Nebulizing Diffuser was my first experience with a waterless model, and it didn’t disappoint. Its sleek hardwood base and glass reservoir made it a stylish addition to my home.
With just four drops of essential oil, this diffuser filled my 2,924-square-foot house with fragrance in seconds. While it has a shorter runtime (two hours), the lingering scent made up for it. Cleaning was a bit time-consuming, as I had to soak the glass pieces in hot soapy water, but the results were worth the effort.
What to Look for in a Diffuser
From my experience, the following features are essential when choosing a diffuser:
• Timer and auto shutoff: Prevents damage if the diffuser runs dry.
• Lighting options: Many models offer LED lights for ambiance.
• Intensity settings: Choose between continuous or intermittent misting.
• Capacity and coverage: Larger tanks cover more area and run longer.
• Easy cleaning: Essential for maintaining the device over time.
How I Tested These Diffusers
I tested each diffuser in various rooms—my 180-square-foot bedroom, 200-square-foot office, and 220-square-foot living room—to evaluate performance, ease of use, and cleaning. I also took note of how long the fragrances lingered and how much oil each diffuser required.
