Though essential oils aren’t medicine, per se, they can certainly help you to lead a more comfortable life. The aromatherapy benefits are undeniable, and if you’re skeptical, go read the back of your Vicks Vaporub. The menthol included in the that has probably been soothing your sicknesses for decades, and you had no idea that you were already using an essential oil. If the menthol can help your breathing, there’s every possibility, even likelihood, that other essential oils can help you with other concerns, too. It’s not a substitute for medical care, but you can probably avoid needing a doctor as often if you properly use your diffuser and essential oils.

Best Essential Oil Diffuser for a Large Room: Everlasting Comfort Humidifiers with Essential Oil Tray
The Everlasting Comfort Humidifiers with Essential Oil Tray will allow you to pick your favorite essential oil and because the oil is added to a separate tray, you won’t go through the oil quite as quickly, even though you do have a larger room to cover. The humidity of the room has less to do with the oil’s consumption and the large water tank means you won’t have to add several drops to ensure enough aroma is emitted.
Whether you use it as an essential oil diffuser all year or not can be entirely up to you. Even after you’ve run out of your oils, or when you’re just not in the mood for them, you can still see the benefits of this humidifier; and that means you’re bound to use it frequently. The oil tray may not really give off a strong aroma once the oil has been consumed but the smell may stick around longer than the diffusers which require you put the oil directly into your water tank. You will want to make sure you’re cleaning the tray because the oil can corrode and make the tray stick otherwise.
There are right around 6,500 customer reviews on Amazon for this diffuser and when that many people have come back to review the product and give it an overall rating of 4.2 stars, you know the product is of high quality.
Everlasting Comfort Humidifiers with Essential Oil Tray Key Features:

Who Should Buy an Essential Oil Diffuser
Essential oils will be more effective at the ails you cannot see than those you can, but as an adult, you probably have plenty of unseen ails that can use a bit of assistance. Probably the most undisputed use of the peppermint to keep you alert and awake. So if you find yourself suffering from a mid-day droop, popping a diffuser on your desk with a bit of peppermint can really get you through the day. Lavender has long been used to relax and relieve stress; your masseuse will often use that essential oil to help relax your muscles, perhaps in conjunction with other relaxing oils like rose and chamomile. Diffusing the oils in the lobby while you wait, or during your massage will help you begin to unwind. If you find yourself struggling with this even at home, a diffuser for these times can help, too. And the best part of this is that even if you don’t see consistent results, your house will still smell amazing, and that alone can put you in a good mood.
As we’ve already touched on, there are several health benefits that you can receive from your essential oil diffuser. The aromatherapy can have a positive effect on your mood, but it can even improve your health, too. Eucalyptus, just like the menthol, can help your breathing if you’re congested but oils can help more than just the common cold. Peppermint may be the only thing to get you through a nauseous period, and diffusing it may make a big difference than for a longer period of time than just popping in a peppermint. Peppermint and lavender combined may help relieve your headache, as well. And if you suffer from migraines, there are likely very few tricks for getting rid of them that you’d pass up.
Important Features to Consider
An essential oil diffuser should do several things well. Here’s what to consider when selecting a diffuser for your essential oils:
- Humidifier. Diffusing an essential oil will automatically release a bit of moisture into the air; that’s why you’ll often see the product description listed as a “cool mist” – releasing oil into the air via water is bound to do that. However, that doesn’t necessarily mean you’ll be getting the benefits of a humidifier if you don’t find a diffuser that’s listed as a humidifier, as well. A humidifier will release warmed air rather than cool and on a bigger scale. You’ll be able to tackle a larger room with a combo and that means you may go through your oils faster. You may find for larger rooms, it’s cheaper, in the long run, to buy a moderately priced humidifier for a larger space and the diffuser for directly next to where you’ll be spending the bulk of your time. For a smaller room, office, or if you’re just not that invested in the humidifier feature, then a good combination will suit you just fine.
- Included Oils. Restocking your oils will undoubtedly be the most expensive component of utilizing essential oils. You can find more or less expensive oil types, and the more expensive oils will be purer. Even if you use the less purified oils, though, you’ll still be spending over $10 for a 0.5 mL bottle and that doesn’t go far when you’re diffusing every day. If you can find a new diffuser that gives you oils included, that’s definitely something to sweeten the pot for you. In fact, a good beginner set with a diffuser and a variety of oils may be the best way for you to try a variety of different oils to test what you like the most so you won’t have to guess each time.
- Capacity and Time. You will want to consider how many liters of water the diffuser can store and how long it will operate on that amount. If you want an oil diffusing for your sick child all night, you won’t want to have to sneak in at 3 am to refill it. You can easily find a diffuser that will go all night or all day, but it’s unlikely you’ll be picking one up that will last all day and night. If you just want it in your cubical during your workday, then make sure you’re turning it off when you step away from your desk, to conserve your time to actually benefit you. Besides, you don’t know if your co-worker wants the same oil side effects that you do.
- Battery Powered vs. Power Cable. It probably goes without saying that the battery-powered diffusers are best for traveling and the cord-powered diffusers will last much longer and operate more efficiently. Battery-powered will also often give you an oil pad rather than a traditional misting diffuser. This means that rather than refilling the tank, you’ll be reapplying the oil to a felt-style pad within the portable diffuser. The pad will need to be replaced and the fan that projects the aroma of the oil into the air will only allow for the oil to travel so far. It has a far shorter range and you will inevitably go through more oil if you use it frequently. However, you can’t overlook the convenience and if you aren’t able to run to a sink to refill the tank of a more traditional diffuser, this may still win out.
- Lights. Diffusers have begun to become almost synonymous with relaxing lighting. You’ll be able to use a large portion of the available diffusers as mood lighting as well as night lights for your bedtime diffusing and that will make them all the more useful for your day-to-day. if you want to create an environment that will give you the maximum amount of de-stressing, then you can’t overlook the lighting and luckily, the diffusers will often take care of that for you.
- Timers. For those who use oil to relax you to the point where you can comfortably fall asleep but do not require the oil diffused all night long, a timer is a perfect solution. Diffusing a bit of lavender and chamomile to help you fall asleep is an excellent opportunity to diffuse for a few hours, and to quietly shut off after you’ve entered into a deep sleep. You can turn it on each morning with a bit of citrus and peppermint to wake you up and set it to turn off after you leave for work so that your home doesn’t have any electronics working all day (and to make sure you’re not wasting the aromatherapy to an empty home).
Frequently Asked Questions
What is an essential oil diffuser and how does it work?
An essential oil diffuser is an appliance of sorts that will allow you to project an oil into the air by diffusing it. The oil can be applied directly to a water reservoir that will work as a humidifier, dispersing the aroma and oil particles throughout the room. A larger humidifier may have an oil pad slot for you to apply the oil to and allow it to blow out along with the humid air, and you will need to replace both the oil and the pad. You can also use a diffuser that will absorb the oil and a small fan to blow the fumes from the oil into your home. As you can imagine these don’t cover as much area, but they’re relatively inexpensive, so it’s a trade-off in which you may be interested. You can also use an aroma heater to warm the oil to make it more potent. Combined with a fan or blower, the oil will disperse.
The aroma benefits of essential oils are the least controversial, so a diffuser is a solid investment even for those who don’t buy into the speculated homeopathic benefits. Some claim absorbing the oils into their bodies can give dramatic health benefits, but the scientific community is not, as a whole, convinced yet. Though the science may not be supportive of it as an alternative to medicine, many doctors will recommend it as a supplemental aid. That is, they’ll suggest that it may not fix a chemical imbalance, but it could improve your mood. And, unless you have other health concerns, there’s a good chance you’ll be risking very little outside of your financial investment. Worst case scenario is you likely to be a pleasant-smelling room.
Is diffusing essential oils safe for your lungs?
If you don’t have any problems with your lungs, then diffusing essential oils in your home will pose no threat – as long as you’re not over-using them. Some people claim they actually see improvement in their overall lung health when diffusing the right essential oils. Though there’s no scientific evidence to support this yet, exploring the benefits of essential oils is still relatively early in research for the scientific community. That being said, if you do have a lung condition, COPD or asthma, for example, you’ll want to avoid breathing in anything extra, and that includes essential oils. The oil particles in the air may cause inflammation or trigger an attack, so err on the side of caution until more research is done.
The most common downside to the diffused oils is when you overuse them and develop a tolerance to the oil. Not only will you stop seeing the aromatherapeutic benefits of oil you can no longer smell, but it could also cause a bit of aroma sensitization. Beyond that, you’ll still need to keep in mind that just because the oils are natural doesn’t mean we can use them without prejudice. If you want to diffuse it in a common room where you don’t spend a lot of time, but want the oil on when you walk through or past it, then you won’t need to be careful, but for a room, you’re in all the time, you’ll probably want to stick with a few bursts of diffusing throughout the day. Some pulmonologists recommend thirty-minute increments with a big break in between.
How long do essential oil diffusers last?
The quality and design of an essential oil are the biggest determining factors for how long an oil diffuser will last. There may not be a hard and fast rule that once any diffuser reaches, it dies, but you can estimate that an essential oil diffuser of quality will last about 4,000 hours. If you plan on using this nonstop, then you may want to look for a diffuser with a warranty; especially considering there are over 8,000 hours in a year.
The oil within the diffuser is easier to track. You’ll be using the oil until the water’s gone in most traditional misting diffusers. Once the water’s gone, so is the oil. A few drops per “tank” will work and that means however long the reserve lasts is how long the oil will, too. For the diffusers that use an oil pad rather than applying the oil directing to the water, you’ll replace as needed, or rather, when you can no longer smell it or it doesn’t have the aroma strength you prefer.
Where do you put an essential oil diffuser in the bedroom?
You’ll want to place it a few feet away from where you’ll be sleeping. By your bed on a nightstand is ideal, but be sure to place it on the far side, not the closest. You may love the smell but too much of it could have the opposite intended effect and keep you stimulated rather than relaxed. Too much of a good thing is still bad, even when you’re using essential oils. If you have a partner who would like to benefit from essential oils, as well, then you have a few options. You can switch sides periodically, either the two of you or the side where the diffuser goes – but that is rather bothersome, so you may not settle on this solution even if it’s where you start. You could get a diffuser for each side of the bed, too; that would make it easier for you each to diffuse the oils that work best for you. So if your partner has a cold and you’re stressed, he can diffuse eucalyptus and you can diffuse lavender. But bear in mind that just because the diffuser isn’t on your side doesn’t mean you won’t see any of the benefits. Opt for smaller diffusers if this is the route you take. Your final solution is the most ideal, but not always (or often) possible: find a place to put it that’s equal distance to you each. In a perfect circumstance, this means you’ll have a headboard or shelf behind the bed that you can pout the diffuser on. You may be able to see the best benefits if it’s placed on a side table by the foot of the bed, but make sure if it aims, that it’s pointed at you.
