How To Use Aroma Oil Diffuser?
To get the most out of your electric aromatherapy diffuser for a large room, all you require is to use it properly with all the care and affection.
Here are a few steps you need to follow:
Choose an appropriate location:
After selecting the room place your device on a flat solid surface, tabletop, solid shelf or a nightstand.
It is good to locate a power outlet and if possible place it near the center of your room so that the scent is distributed evenly around the area.
In general, you should avoid the place which gets direct exposure to the sunlight or is near to the fan.
Since you are using water in your device for humidification, it is good to place a towel underneath. This will prevent the surface from getting damaged due to stagnant water (if any).
Fill the water:
Once you have placed your device right, it’s now time to fill it with water. You can bring the reservoir close to the tap and fill it with clean room temperature water.
If you are unsure about the quantity, you can refer to the user manual that may have provided you with details on how much water to use.
Make sure that you do not overfill the water, failing which may leave your device non-functional.
Add your favorite essential oil:
Now it’s time to add a few drops (5-10) of pure essential oils. You can either choose to have a single oil or can try an essential oil blend of your choice.
For me, 5-6 drops are enough to get a refreshing scent in my room. But if your room is large or in case you want the stronger smell, you can try adding a few extra drops.
Turn On the device:
After you have filled your device with water and essential oils, it’s now ready to get started. Place back the cap of the diffuser and plug in the device to turn on.
If you have settings on your device (like timer, LED lights, etc.), just set the features based on your needs.
Within a few seconds, you can start enjoying the fresh feel in your room, even when it not ventilated with windows.
Where to Put Your Essential Oil Diffuser?
While there is no such “ideal” place where you should put your oil diffuser, there are definitely a few guidelines you may follow while putting it in your room!
These will help you in avoiding the leakage or spills that are common while using the large oil diffuser machines that use water and essential oils.
First of all, when placing your oil diffuser it’s better to put it on the table or a desk which is at least 2 feet above your bedroom floor.
Make sure that the table is placed at a distance of 3 feet or so from your bed so that it can evenly spread the moisture and aroma into the room and not only near to your bed.
You can also place them high on a shelf which is stable and not susceptible to any kind of accidents.
The thing you need to care about is – just avoid placing the unit on top of (or very close to) wooden surfaces.
This is due to the fact that the mist of droplets that carry essential oils from the unit can damage the wood furniture.
Few other tips for placing your diffuser at an ideal location are:
- Place the unit on a non-metallic surface
- Put a tray or any other water-resistant cover underneath
- Do not place the unit on carpet or any other cloth that can get damp
- Avoid keeping it near to window where there is a source of direct sunlight
Steps for Cleaning Your Essential Oil Diffuser
Before cleaning the diffuser, it should always be compulsorily removed from its power socket. Then follow the cleaning steps as below:
- First of all, partially fill the water tank making sure that it does not cross the maximum line.
- The next step is to get rid of the oils that got smeared inside the diffuser and spilled over on the outer area. For this pure white vinegar of 10 drops should be added.
- Switch on the diffuser and let it be on for 3 to 5 minutes for the vinegar and water combination to blend well in such a way that it scatters on the whole diffuser for effective cleaning without leaving any spot untouched.
- After this, the diffuser should be drained fully.
- As an additional step to ensure complete cleaning, check every nook and corner of the diffuser and clean them with a cotton pad soaked in vinegar.
- Wash thoroughly with normal water and drain it again.
- The last step is to pat dry the diffuser with a dry towel or cotton balls.
Even though the above steps can be followed by you for cleaning the diffuser, it is best to approach the service center of your diffuser brand to get it cleaned hassle-free without your intervention.
If it is under warranty still, the best choice is to get it cleaned by a trained customer service representative.
If you are so inquisitive in nature and want to do it by yourself, you can get the help of the diffuser cleaning manual that you got along with the product purchase and get it cleaned.
Some diffuser brands like Young Living Diffusers make the warranty void if they come to know about your diffuser get cleaned by Vinegar or other elements other than those strictly given in the cleaning manual.
Should you clean the unit after every use?
Almost all of the diffuser brands give guidelines to clean the diffuser after every use, which many may find as a time-consuming process.
But prevention is better than cure and in reality, many don’t do it after every use due to sluggishness saying it can be done another time.
But, practically speaking that another time will never come until one realizes it is long overdue.
It is best to avoid the above mistake if you really care about the performance, durability, and long-life of the diffuser.
As the oils used in essential oil diffusers are of corrosive nature, it is a good practice to cleanse it immediately after every use.
The odor of residual oil, when mixed with new oil, may affect the pleasant smell.
So, it is suggested to empty the essential oil diffuser after every use fully and clean it with a cloth before another use.
What Size Diffuser for Bedroom/Large Room?
Well, choosing the right size is one most important aspect – when you are buying a good aroma oil diffuser for your bedroom.
Most probably while buying you may have come across tank capacities ranging anywhere from 50ml to 500ml.
Also, there are extra-large ones that can go beyond up to 1000ml capacity.
The idea is not to pick the maximum size as it can cost you much higher.
Before picking one, determine the size of your room where you want to place the unit. And based on the size of the room you want to cover get the one that is most ideal.
For most of the families, 300ml to 500ml capacity is a good fit. You can go to it unless you have a very huge area to cover.
Remember that the machine you are selecting should be big enough to cover the area you are seeking to scent.
What Essential Oils to Use with Diffuser for Stress?
Now when you have chosen your favorite diffuser model, it is good to know about some of the best smelling aromatic essential oils that can be used with the machine safely.
As pure organic aroma oils are expensive to buy and not all of them are safe to use in diffuser machine, you should do proper research before buying them online.
Here is a list of 10 essential oils that can be safely used with your room scent diffuser. These are best smelling and are also helpful in relieving your stress and depression.
✅ Lavender Oil:
Pure Lavender oil is my top favorite as it not only helps in relaxing and unwinding but can also help to sleep well.
This oil is the most common and highly used oil to treat nervous disorders. When you inhale this, it breaks down the fast brain wave (which causes anxiety) and replaces it with a slow brain wave.
When buying make sure that you purchase only good quality Lavender oil (one which is high in esters and low in cineol).
This oil helps in releasing all the negative feelings that could lead to depression, insomnia, etc if not released.
It has a fruity fragrance that calms the hypothalamus, directs your nerve energy away from addictive, unproductive behavior and helps you relax.
It can be applied to the neck, back, and feet.
✅ Rose Geranium:
This oil’s floral aroma gives a pleasant and enhanced relaxation feeling and helps balance your hormonal levels.
It stimulates the lymphatic system and relieves you from anxiety, depression, and stress.
✅ Clary Sage:
This oil is best for nervous disorders like depression and anxiety.
Only using this oil cannot cure you completely but it can help a lot while you are under treatment for such nervous disorders.
This oil calms the nerves and gives a wonderful, relaxed feeling, quite similar to the drug valium.
It increases the GABA activity in your brain and regulates the emotions of depression, anxiety, and excitement.
✅ Sweet Marjoram:
This oil gives you a relaxed feeling by regulating blood circulation and also helps treat insomnia.
It can be combined with other oils for better effect.
✅ Wild Orange:
This oil effectively helps in lifting your mood by improving blood circulation and detoxifying the gallbladder and liver.
Rub it on your neck, back or feet to relieve from anxiety and panic.
✅ Roman Chamomile:
This oil smells sweet to fruity and is effective in treating diseases like insomnia, vomiting, ADD (Attention Deficit Disorder) and restlessness.
It is considered highly valuable in treating anxiety, stress, fear, tension, and nervousness.
It stabilizes, grounds and harmonizes your mind to treat depression, anxiety, exhaustion, nervous stress, and other stress-related conditions.
These oils which when used with aroma diffusers effectively work on the right part of the brain and help diminish anxiety, stress, depression and other related issues.
What to Look for When Buying a Room Diffuser Online?
No matter how much stress, bad in mood and tired you are; essential oils with the art of diffusion can easily calm your mind, body, and mood.
In case you are already planning to buy a great aromatherapy diffuser for your bedroom, living room or the whole house; here are a few essential things you need to look for in them…
When shopping for a scent diffuser for a large room, you may come across various different types that offer varied features.
While most of the large room diffusers utilize water for scenting and humidifying the air, few are there that do not use water or heat.
These come at an additional cost and can offer a few additional health benefits. Depending upon your budget and personal preference you can choose the one that is most suitable for your family.
As you are looking to buy a perfume mist diffuser for a large room, you should essentially check for the reservoir or tank capacity of the unit you are buying.
A large reservoir in the machine (with 300ml or more) will allow you to get the mist of fragrance for a longer period of time and is therefore good to buy.
✓ Timer and Mist:
An inbuilt timer in your device actually allows you to set for how long your diffuser should run before it gets switched off automatically.
For instance, if you want to diffuse the aroma oils in your bedroom all night while sleeping, you can set it accordingly with a low misting option.
This will slowly diffuse the fragrance (at a slow mist rate) to help sleep you better without worrying about your sleeping problems.
With a slow or high misting level you can also set your machine to produce high or low aroma, which should depend on where you keep the unit in your home.
✓ LED and Night Light:
This is another good feature that you may not want to miss out when buying a diffuser for your large king size bedroom or living room.
Many people prefer having a dim light to get a soothing effect in the bedroom at night.
As colorful LED lights in your machine make it act as a night light, you never have to use additional lights in your room for sleeping.
Especially if you have children at home, you will find these oil diffuser for nursery helpful.
And the best thing is, being completely adjustable you can set the brightness of the lights according to your liking or can even switch them off completely.
✓ Noise Level and Auto Shut Off:
Annoying noise that distracts your mind (while working or while sleeping) is a problem with much cheaper quality oil diffusing machines.
Hence the level of noise the device produces while working should also be taken into account while buying.
Additionally, it’s also important that your unit comes with all the safety features like auto shut-off.
This allows the machine to shut down automatically when they run out of water. This feature also ensures that your device doesn’t burn out or waste any electricity.
✓ In addition to all the above important factors in your diffuser model, it is also important that you choose the best reliable store for buying one.
Although most of the aroma diffuser dealers or manufacturers have their own official website, I personally prefer buying at stores like Amazon as they offer various discounts and coupons for making an affordable purchase.
The room fragrance diffuser machine they sell are not only branded, high quality and affordable but also comes with a proper warranty.
I have recently bought a URPOWER diffuser here and am feeling in love with it. This not only works great but also looks beautiful in my room!
In case you are not interested in doing much research you can consider this machine without any second thought.
