Essential oil diffusers are excellent at giving your space a soothing ambiance. Imagine yourself coming back from work exhausted. Wouldn’t it be best to have something to relax your nerves and remove the stress from your bones? Essential oils, with their soothing aroma, can do precisely that. All you need to do is add a few drops of your favorite essential oil in a diffuser, and your entire space will become amazingly fragrant and help you unwind. Not all diffusers are not made the same. Choosing a diffuser that can address your needs while providing long-lasting performance is important. There are many factors to consider before you decide to buy a diffuser; for example, you don’t want to constantly refill the diffuser, and it should not make too much noise. Let’s go into more factors below.
Decent water tank capacity is vital as it directly impacts the total run time of a diffuser on a single fill. Imagine having to refill your device twice daily just because it has a small water tank. As that is not something anyone wants to do, consider getting a diffuser that comes with a spacious water tank of around 300-500 ml. This would ensure that your diffuser will not need constant refilling, and depending on the diffuser you get, it should provide you a total runtime of up to 10-20 hours on a single fill. While you may not run your diffuser continuously, a large water tank may be nice to have. I prefer to get larger water tanks with my appliances. Refilling water, even if it is not too difficult, is just one more chore I try to avoid. That’s why I recommend opting for a 500 ml tank. Of course, you should always check the total runtime of a diffuser to ensure it fits your needs and would not be inconvenient to maintain.
If you want to run your diffuser frequently without distraction, you want it to produce as little noise as possible. Thankfully, most essential oil diffusers use advanced ultrasonic technology to create a super-fine mist without making any significant noise. That said, you should always check a device’s noise level in decibels before buying to ensure it is low enough. This is especially essential if you are very particular about keeping your space quiet at night. You may be like me and enjoy some background noise to fall asleep. Diffusers can provide enough white noise to make dosing off even easier. If I were to get a new essential oil diffuser to run at night, I’d determine where to place it partially based on how loud it is and how much white noise it produces.
There are two types of mist: cool and warm. Although it is very tough to find a diffuser that produces warm mist anymore (it takes more power and time), you can still find one if you want warm rather than cool mist. However, a cool-mist results in a calmer ambiance, and you can run it through the night without the air becoming too warm. Most essential oil diffusers you will find produce a cool mist through a super-quiet ultrasonic misting method.
Two misting modes are typically offered by essential oil diffusers: intermittent and continuous. The intermittent misting mode pauses after every 30 seconds before resuming operation. This effectively prolongs total diffuser runtime, making it easier to maintain. This helps conserve essential oils, as each refill is spread out over a longer time.If you don’t prefer intermittent misting and want to fill up your space with the scent of your chosen essential oil, then the continuous misting mode is just for you. Although this will shorten the total runtime on a single refill, it will keep your space pleasantly fragrant for as long as the water tank runs out. You should opt for a diffuser that offers both misting modes. We recommend searching for diffusers with both misting methods.
Typically, essential oil diffusers come with various color modes, ranging between five to eight colors. Depending on your preference, these color modes can be set either on an automatic cycle or fixed to just one color. Having color modes can set the ambiance of your space, so we recommend opting for a colored light diffuser.The light of the diffuser should not be fixed in brightness. The diffuser should allow you to choose between bright and dim modes. You can change the setting depending on your mood. For example, I like a soothing light to fill my room without disturbing my sleep. Thus, I would want my diffuser to be set on dim.
An essential oil diffuser that comes with three to four timers allows you to set the durations of use. This ensures that the diffuser does not over-humidify your space at night and helps conserve essential oil use. While some diffusers come with three to four-timer settings, a variant with just one or two-timer options is also a good enough choice.
An essential oil diffuser must have some safety features embedded into its design and functionality. The most important feature is the automatic shut-off feature. This ensures that the diffuser turns off automatically when the water level reaches zero to prevent the device from overheating. You can look for additional safety features in the diffuser, like leak proofing and safe material quality.
Although this is a rare feature, some essential oil diffusers come with a remote control allowing you to operate the device without physically making your way to it. This is great if you want to place the diffuser on a distant corner that would be inconvenient to access. However, if you place the diffuser on your bedside, you don’t need one that comes with remote control as it would be reasonably easy to operate.
A compact essential oil diffuser is a blessing, as you can place it almost anywhere. The most common location to place a diffuser is on the bedside table. As bedside tables are typically small, it would be wise to pick a diffuser that can easily fit on there without disturbing other elements.
The diffuser you choose must be made with safe, eco-friendly materials such as PU plastic that is also BPA-free. This ensures that the device will last a long time and not threaten your health. When it comes to buying a product, quality materials and build are very important to me. If I don’t need to replace a product, that’s more money that stays in my wallet.
According to Grace Angelique Magalit, a plant molecular biologist and research and development head of Culture, "Though generally safe, there are some essential oils that should be diffused with caution. Peppermint, Thyme, and Lemongrass should be diffused only using a few drops as they can cause throat and mucous membrane irritation." Check with your essential oil provider for warnings and use recommendations.
Yes, you can safely have the diffuser on during the night without worrying about any safety risks. Just make sure the diffuser has a safety shut-off feature to turn off when it runs out of water automatically.
Just a few drops of oil should suffice. If you start feeling nauseous or get a headache, you might be adding too much oil.
