How to Find the Best Essential Oil Diffuser

An essential oils vaporizer can give your home a boost of ambience and calm. They’re wildly popular and for good reason! You may be wondering: how does a diffuser work? What’s the difference between a humidifier and a diffuser? You’re in the right place! We’ve researched the ten best products for the money. Essential oil diffusers use ultrasonic technology to “vibrate” essential oils mixed with water into a fine, cool mist. Before we get to our essential oil diffuser reviews, here are a few things to look for when shopping for the best oil diffuser for large rooms and small rooms alike.

Best Essential Oil Diffuser

Water Capacity: A high capacity usually means a higher run time, which means refilling less often! But it also means the diffuser will take up more space.

Best Essential Oil Diffuser for Large Spaces

Diffuser Capacity: How much is the diffuser actually putting out each hour? For a large room, a bigger number is better for a greater impact.

 How to Find the Best Essential Oil Diffuser

Auto Power Off: No need to worry about the diffuser if you forget about it and leave it on--these diffusers will shut off when water runs low.

Best Essential Oil Diffuser for Large Spaces

Max Run Time: Some diffusers run for a long time but diffuse very little into the air, and vice versa. A long run time means less refilling!

Dimensions: How much space does it take up? See if you have the space for the diffuser you have in mind before buying!

Warranty: How long does the manufacturer back up their product? Most diffusers have a one-year warranty.

A ring of LED lights around the base of the humidifier and on the top of the diffuser provide ambient lighting in seven different colors. It can provide humidity to an area of 65-82 square feet! You can set the lights to dim or bright modes, and choose one color or let the diffuser cycle through the full spectrum.

Budget Pick
Looking for a simple oil diffuser for your desk or bedside table? This little diffuser is a great option.

The always-on mode lasts 3 hours, perfect for studying or working on a project. The 100ml capacity is on the small side, so it works best if you want to sit near the diffuser to enjoy the scent. Its small size makes it great for work or travel, plus you can use it as a night light or slow-motion disco ball! The seven LED colors can be set to cycle through or on just one shade. The white plastic body of the diffuser lights up all over and can be safely placed in a child’s bedroom.

BellaSentials Oil Diffuser

Need a diffuser that can handle rooms up to 500 square feet and doesn’t constantly need refilling throughout the day? The BellaSentials diffuser has a 350ml water capacity, almost three times what the average desktop humidifier can offer. It lasts 8 hours on high mode, or set it to low mode and forget about it for 12 hours! You can also play around with the 7 LED lights, which can be set to rotate or to one color. This is a larger-capacity essential oil diffuser, but it’s still portable. The dark bamboo finish keeps the low, rounded design of the diffuser from reminding you too much of a retro CD player, too. Basically, this is one diffuser you should consider if you have a large room and want a long-running, high-capacity diffuser.

The wood grain look combined with the nature-inspired vase shape makes this diffuser a modern bohemian accent!

Young Living Home Diffuser

The now-famous Young Living brand offers a range of diffusers, but we liked this rose-shaped white ultrasonic diffuser for its small size and neat design. Here’s our Young Living diffuser review, in brief: It features an ultrasonic diffuser system that generates waves at 2.5 million times per second--sounds impressive, right? The basic ambient light (no color-changing here, folks) can be switched on and off. You can choose between always-on and a setting that alternates 30 seconds on with 30 seconds off to go longer between refills. The diffuser shuts off automatically and is easy to fill with your favorite essential oil. You also get a sponge for cleaning it, score!
