Creating the right environment for sleep goes beyond your bed. If you have trouble sleeping, adjustments in lighting, sound, and habits like disconnecting from screens earlier can make a huge difference is how you fall asleep. Another factor can be aromas; the scent atmosphere you set up in your bedroom (or wherever you sleep) can help have a calming effect, which can in turn help you fall asleep faster and sleep deeper. While there are countless sprays and plug-in air freshener options on the market, essential oil diffusers can be a great option for infusing scent into your room.

Diffusers can help you cut down on your environmental impact by avoiding the packaging associated with disposable air fresheners. And, with the glut of essential oil options out there, you can tailor scents to your specific needs, even blending scents you enjoy to create your hybrids. Portable diffusers are especially beneficial because they can be easily moved from room to room to maximize the coverage of the aroma. Here are some of our favorite portable diffusers you can get right now:

Portable diffusers are a great way to control the ambiance in your home; they’re cost-effective ways to add additional mood lighting and scent while also reducing the waste commonly associated with spray or plug-in air fresheners. Because of the rise in popularity in yoga and aromatherapy over the past decade, there has been a massive influx in the number of affordable diffusers on the market. Here are some of the factors we considered when selecting our favorites of the bunch:

Being able to control the amount of mist, or the time it takes to empty the fill tank was a big consideration. Having the ability to quickly add scent to a room with a one or two-hour mist in addition to a slower setting that could last the duration of an entire night were both ideal in a diffuser. Especially if you’re using the diffuser while you sleep, having a six-hour mist setting at minimum was ideal.

Most diffusers on the market feature some sort of lighting setting that allows you to control ambiance in a bedroom or nursery even beyond aroma. We tended to favor devices that had multiple LED lighting options to control mood, with special weight given to those where the lighting control was customizable and simple (choosing an individual lighting color versus a constant cycling of colors). Devices that offered additional ambiance control options like Bluetooth speakers were all the better.

Because these are portable devices and not large-capacity diffusers that are meant to stay stationary in a yoga studio or aromatherapy clinic, the volume of liquid the device could handle became a consideration for us. We favored devices that had large enough fill capacities that would last a long enough time without having to be refilled hourly, but not so much that they became a pain to transfer from room to room.

When picking the best portable diffuser for your needs, there are some considerations you should be making beyond the mere price point. The good thing about diffusers is they’re relatively inexpensive, and in the long run, can end up saving money compared to buying disposable air fresheners. When choosing the right device for you, also consider:

If you’re curious about how scent can play a role in your sleep, investing in a diffuser can be a great option. These relatively low-cost devices give you more control over the aromas you use in your home, and can be a simple jumping off point to finding the right scent which encourages relaxation and sleep. The ability to mix scents, as well as reduce the waste commonly associated with disposable air fresheners makes them additionally appealing. If that wasn’t enough, they also often feature LEDs which can help set the mood for even further control of the ambiance in your bedroom or in a nursery.

The past decade or so has seen a rise in the number of affordable, effective essential oil diffusers on the market. Companies like HOMEWEEKS and InnoGear are a couple of our favorites, creating simple, effective diffusers that don’t break the bank.

Though there can be a number of issues that can arise with a diffuser, if it’s not functioning properly, the first step would be to thoroughly clean it. To clean a diffuser, fill it to about half its capacity and add ten or so drops of white vinegar. Run the device for five to ten minutes and then thoroughly clean out the tank; this should help get the diffuser back to its original state.

Personal diffusers disperses essential oils into the air as a fragrant mist.
