Admittedly, I’m a bit obsessed with anything that smells good and makes my space feel like a zen yoga studio. I spend more-than-acceptable amounts when my favorite brand of candles has their bi-annual sale, and I’ve been known to set off the smoke detector with incense. That being said, my one true vice is essential oils and the machines that adequately dispense them. If you’re in the market for the best aromatherapy diffusers and humidifiers, you’ve come to the right place.
First thing’s first: Humidifiers versus diffusers — is there a difference, and if so, what is it? The simplest way to explain it is that almost all diffusers are humidifiers, but not all humidifiers are diffusers. In other words, some machines (humidifiers) release moisture into the air, but their internal mechanisms can’t handle the addition of essential oils. The best aromatherapy diffusers, on the other hand, can. Most also use water as their main vehicle for dispersing oils into the air, thus also hydrating your space in the process.
As a result, your home smells awesome, your air is easier to breathe in, your skin is happier, and your mood might even brighten a little bit. If you’re loving the sound of all that, it’s probably time to find a solid diffuser that suits your lifestyle. Here are nine of the best available right now.
The Top Pick: Pure Daily Care Ultimate Aromatherapy Set
If you’re in the market for your first diffuser and want something that’s equal parts stylish, practical, and an incredible value, opt for the Pure Daily Care ultimate aromatherapy set. It has all the most popular features, like seven LED color options and three pre-set timer functions — but it also comes with 10 free therapeutic-grade essential oils to get you started. It’s made entirely from BPA-free materials with a classy wood-grain finish, and the ultrasonic mist is cool, quiet, and works alongside a 400-milliliter capacity. When it runs out, it’ll turn off automatically for your safety.
Glowing Review: “I’ve had many diffusers in my life and this one is my favorite! […] I can’t believe I got this diffuser and all the oils for the price I paid! That is unheard of in the stores.”
The Best Budget-Friendly Diffuser: InnoGear Essential Oil Diffuser
With over 92,000 reviews and a 4.5-star rating, the InnoGear essential oil diffuser is easily the most popular unit on Amazon. It’s also one of the most affordable. According to reviewers, it “puts out a strong, thick mist [that] lasts a whole day,” all thanks to its whisper-quiet ultrasonic operation. It also has seven different colors of LED mood lights that you can opt to filter through or set on one in particular. On continuous mist mode, it’ll last you up to nine hours on one refill, and on intermittent mode, you’ll have fresh, hydrated air for up to 11. The best part? It’s $15.
Glowing Review: “I’m a certified aromatherapist. For the price, this is a great little diffuser. It REALLY is. I’ve purchased this many, many times for housewarmings gifts and get-well care packages.”
The One For Air Purification: PureGlow Crystal Himalayan Salt Diffuser
Diffusers are trending right now. So are Himalayan salt lamps. Combine them into one genius unit, and you’ve got the ultimate relaxation duo. The PureGlow Crystal has a 160-milliliter water tank filled with real, hand-crafted Himalayan salt crystals. The diffuser releases your favorite essential oils into the air in the form of a cool mist, while the salt rocks create negative ions that purify your space of allergens, pollutants, and bacteria. There’s even a built-in light with five levels of brightness, and all the touch-activated features can be used separately or together depending on your needs.
Glowing Review: “Diffusers and Himalayan salt rock lamps are two of my favorite things and when I saw them paired together so beautifully I had to buy it!”
The Editor’s Pick: LEVOIT Essential Oil Humidifier
If you’re looking for a serious humidifier with a large-capacity tank (one that can tackle big areas, but still works alongside essential oils), consider this LEVOIT humidifier, which outputs both warm and cold mist. “This humidifier has been a game-changer for me during those super cold months when my skin normally gets dry and itchy!” wrote Danielle Kraese, BDG Commerce Editor. “I love that it’s got a sleek, modern design that blends right in with the rest of my bedroom decor, and the interface is easy to use (plus, the remote is so convenient). On top of that, the essential oil diffuser is amazing when I’m feeling congested or sick.” It features a 6-liter capacity for up to 60 hours of continuous use.
Glowing Review: “We splurged and got this one and it was worth it! It is very quiet and we very much appreciate how it has both cool and warm mist modes (it’s hot where we live). We also like being able to add essential oils.”

It even has two misting modes and seven color-changing light options.
Glowing Review: “I really love using this in my car. I fill in the morning and it lasts for my morning and evening commute and could keep on going! 2 hours plus some in terms of capacity. I love that you can have the light on or off.”
The High-End Pick: Teo Beech Wood Diffuser
For those in the market for a quality diffuser that doubles as a sleek and elegant statement piece, there’s the Pilgrim Teo diffuser. It’s one of the best luxury options on the market because it has a handmade ceramic cover alongside an FSC-certified beech wood base.

A Model With Metal Cutouts: EQUSUPRO Aromatherapy Essential Oil Diffuser
For the candle lover in your life — and maybe that’s you — there’s the EQUSUPRO essential oil diffuser. Its warm light, color-changing LEDs, and intricate metal encasing make it look almost like a candle, but it’s actually a safe and convenient way to add essential oils and hydration to your space. The 100-milliliter tank can run for a few hours, and it’s earned over 13,000 reviews with an overall rating of 4.5 stars. If you don’t love the tree cut-out, it also comes in butterfly, deer, and oil designs.
Glowing Review: “I’m so in love with my new diffuser. I decided to try it out because I was spending a ridiculous amount on candles. All I need is a drop or two of oil and it runs for about 6 hours despite being so small. I love all the colors too! Great purchase.”
A Mini One For Your Desk: BBSKIN Mini USB Essential Oil Diffuser
Its space-savvy footprint, sleek design, and USB plug make the BBSKIN USB diffuser the best pick for your work desk. Still, despite its size, its 80-milliliter tank hydrates your air and its strong cool-mist output works well alongside your favorite essential oils. When the tank runs dry, it automatically shuts off, and since you can power it with a laptop or battery bank, it’s one of the most portable options around. It even has a seven-color LED light and a BPA-free construction.
Glowing Review: “It’s nice and small for my desk and holds enough water to run through most of my work day. You can’t really smell the oil until you’re right at my desk, which is also perfect for me because I don’t want to intrude on any of my coworkers work environments.”
