I’m a Proud Homebody, and These Essential Oil Diffusers My Home Smell Amazing (2025)

Our Top Picks

After testing dozens of essential oil diffusers, I can’t recommend the Asakuki Premium Essential Oil Diffuser enough. I personally use it daily in my home and love the large water tank, customizable light and mist settings, and easy-to-clean tank.

With a 500 ml tank, this has the largest water capacity of any diffuser we tried, meaning you won’t have to refill it often. While testing, I only refilled it every day or two (some of my other diffusers turn off after 4 hours), which really impressed me.

This small but mighty diffuser produces a noticeable aroma in my room, though it doesn’t necessarily permeate throughout the rest of my home. I love how adjustable the diffuser is—it has multiple modes, different mist intensities, and an automatic shutoff. I easily switch the modes to fit my needs, including different mist intensities and colors, which I love to use as a nightlight.

After using this diffuser for months, I love how easy it is to maintain. I haven’t noticed musty odors or scale buildup. I’ve cleaned this product in the sink without much effort, though I don’t find the need to clean it super often thanks to how great it still works.

While this product is marketed as a two-in-one humidifier and diffuser, I don’t think it has much of an impact on the overall humidity in my home, so I wouldn’t recommend purchasing it for that reason alone. Regardless, I love how efficient and easy this works; I can set it and forget it for the rest of the day.

If you're not sure about investing in a diffuser, I recommend the Homeweeks Aromatherapy Essential Oil Diffuser—it’s the least expensive design on our list, yet still a powerhouse at delivering soothing aromas.

Using this diffuser is quick and straightforward—simply remove the top, add water, and drop in essential oils. It is highly effective, with a noticeable scent permeating multiple rooms and lingering even after it stops running. Additionally, we loved how silent the operation was during our tests.

You can choose an intermittent mist, which lasts around six hours, or continuous mist, which lasts around three hours. The diffuser also offers seven colorful lights with adjustable brightness, which can act as a nightlight or add to your room's overall ambiance.

This diffuser works just as well after six months as it did when it first arrived, even with continuous use (though it only runs for about three hours continuously.) This doesn’t bother us much though, and we still think it’s highly effective, easy to use, and compact.

_{Type: Ultrasonic | Material: Polypropylene | Size: 6.61 x 4.72 x 4.72 inches | Capacity: 100 mL | Power: Corded electric | Automatic Shutoff: Yes}

Convenient, effective, and versatile, I think the Canopy Diffuser is well worth the splurge (I have the Canopy humidifier and also love that product!) This essential oil diffuser tested impressively well, and we love its minimalist design, portable size, and convenient evaporative quality. While it’s not exactly quiet while operating, it sounds like a light fan and almost doubles as a noise machine.

This unique model offers two different diffusion methods: a diffusion well and an aroma puck. The puck and oils give off a subtle scent, while the well and oil bottle dumped upside down inside the diffuser allow for more scent to spread throughout your home.

While we’ve found certain ultrasonic diffusers difficult to clean, we love that this waterless diffuser doesn’t harbor bacteria or mold in hard-to-reach areas. It requires virtually no maintenance other than the occasional wipe-down.

One downside is this model doesn’t have an automatic shutoff. However, this didn’t bother us during testing, especially since we preferred to keep it running over long periods. Our only complaint is you’ll need to replace both the well and pucks regularly, which increases the overall cost.

_{Type: Evaporative | Material: Not listed | Size: 4 x 4 x 4.2 inches | Capacity: N/A | Power: Corded electric | Automatic Shutoff: No}

I love the InnoGear Essential Oil Diffuser and its truly intuitive design—the stream diffuses from the side of the lid rather than the middle so you can aim it toward you, which is especially helpful at night to better direct the scent across your pillow.

This diffuser is lightweight and easy to move around. During testing, we transported it from the bedroom to the bathroom to use instead of candles or air fresheners when we had guests.

The diffuser’s performance is effective, though we found the aroma a bit more subtle than other options we tested. However, the scent permeated quite nicely in smaller rooms, and we were satisfied with the amount of scent produced.

You can program either intermittent or continuous mist modes, and the diffuser will shut off automatically when the water runs out. The continuous mist mode lasted as long as six hours before stopping. Using the two buttons on the base of the unit, you can also control the light and mist settings independently.

We still love this essential oil diffuser after six months of daily use, as it has maintained its effective and quiet operation over time. We found cleaning it so easy and do so about once a week: Just wipe it down, run it under hot water, and air it out.

_{Type: Ultrasonic | Material: Polypropylene | Size: 3.9 x 5.5 inches | Capacity: 100 mL | Power: Corded electric | Automatic Shutoff: Yes}

If you want fragrance to extend throughout a larger area, consider the Organic Aromas 2.0 Nebulizing Diffuser. This waterless oil diffuser is great for those looking for a more potent, concentrated aroma (which I love) since the essential oils are not diluted as they typically would be with ultrasonic models.

To use, simply open the glass lid, drop the essential oils into the diffuser, and turn the knob. The diffuser comes with a light and dimmer switch to control the scent level. There is a pre-programmed usage cycle, which will run for two hours intermittently (two minutes on, one minute off) before automatically turning off, and color settings that can change periodically or stay one color.

This diffuser is highly effective and fills up an entire small space over its two-hour cycle. While it’s suitable for larger areas, I love that it offers an adjustable output in case you prefer a more subtle scent or plan to use it in a smaller space.

We used this diffuser continuously for six months, and it continues to impress. The flask and lid are removable to quickly wash, dry, and use again. Because of the small opening, you can’t physically scrub the inside of the device, but you can rinse it out.

Additionally, despite some concerns about not having a continuous output mode, we’re happy with the intermittent usage cycle, which allows the scents to cascade across your space in comfortable doses. Just be aware you won’t be able to leave this diffuser on overnight because of the two-hour automatic shutoff.
