There are four different types of aroma diffusers: heat diffusers, ultrasonic or humidifying diffusers, evaporative diffusers, and nebulizing diffusers. Below, we discuss the types in more detail.
They are usually inexpensive and available in different designs to suit different interiors. Their gentle scent combined with a dim light will help you relax, making it perfect to use before sleeping. Just take note that the scent may be quite weak, so it’s best used for smaller rooms. It’s also not recommended for households with children or pets as they may knock things over.
For those who want to give their homes a constant and balanced fragrance, purchasing a reed diffuser is a great start. It works by allowing the essential oils to travel through the reed or wooden sticks and evaporate into the air. The reeds are usually made with rattan wood, and since you can leave a reed diffuser unattended, there is little maintenance required for this aroma agent.
Usually, 100 ml of essential oils in a reed diffuser can last around a month. Once you start noticing that the scent is getting weaker, simply flip the reeds over to reverse the airflow and prevent the sticks from getting clogged. Overall, a reed diffuser uses natural, eco-friendly materials and takes little effort to maintain while providing a stable and mild fragrance for your home.
This disturbance is what releases negatively charged molecules into the air. The fragrance will spread throughout the room quickly, but since the oil is diluted in water, the fragrance is weaker. Ultrasonic diffusers are recommended for those that want to remove unwanted odors or create a spa-like ambiance.
Just make sure to clean it regularly as mold and bacteria can grow in the water reservoir. They can also double as humidifiers, and there are some ultrasonic humidifiers that allow you to add essential oils into them.
The evaporative diffuser or humidifier has a different mechanism from the first two types. Instead of using water or heat, it uses a fan to blow the air through the room. You can drop your essential oil solutions on a pad or a filter inside the device, and the moisture will be evaporated through the blowing action of the fan.
It is quite convenient to use, but unfortunately, it calls for more frequent washing. The slats in the vents tend to trap dust, and if left unwashed, the force of the air blowing through the vents could also send these dust particles up into the air, defeating the purpose of air-purifying or refreshing.
We recommend these for people who want to enjoy the natural scent and therapeutic properties of essential oils. However, most nebulizing diffusers use a motor that can be noisy, so make sure to check the reviews or product descriptions. It also uses more essential oil, so be aware that you might have to spend more on your essential oils.
One of the benefits of having an aroma diffuser in your home is that it can create a relaxing environment and even help you fall asleep better at night. If that is one of the reasons why you're looking into diffusers, then it would be ideal to look for diffusers with longer operating hours so that you can worry less and sleep more throughout the night.
The most common type of diffuser for overnight use is ultrasonic or water diffusers. This is because they have a longer run time, make little to no noise at all, and usually have a timer or a feature that automatically shuts itself down when the water supply in its basin gets empty. Ultrasonic diffusers are also inexpensive, so you can definitely purchase one without hurting your pocket.
Buying an aroma diffuser, especially among the high-end ones, can be expensive. To make sure that your investment is worth it, you can try looking for additional features that come with your scent diffuser. Among the common ones are mist control, LED lights, auto shut-off timer, built-in speakers, and remote control features.
Aside from that, you should also consider aroma diffusers that double as humidifiers allowing you to enjoy two benefits in one device. Also, there are some aroma diffusers with oils included already that you can use for your device. That is an amazing freebie especially if you still haven't decided yet on what scent to use and want to try different ones first. before making a purchase.

Below are some of the most asked questions on the web answered by the mybest team.
There are aroma diffusers that also function as humidifiers. This is common with ultrasonic or water diffusers, wherein aside from having a compartment for essential oils, it also comes with a water container for the device's water supply needed for humidification.
On the other hand, there are also aroma diffusers that can not humidify the air. An example is nebulizing humidifiers which only use essential oils and do not require water at all. This means that this type of diffuser can only disperse scents from essential oils and can not really spray water-based mist into the air.
When you are using an aroma diffuser for your home, ideally, you want it to be mild and balanced instead of being too intense and overpowering. After all, the goal is to create a calm and relaxing atmosphere for your home. Adjusting the amount of essential oils you put in a diffuser is one way of controlling how powerful you want its fragrance to be.
It is recommended to use only 3 drops of essential oils for all types of aroma diffusers. This amount is enough to make the scent noticeable without being too strong. If you have a small or large room, you can also decrease or increase the amount of oils that you put in your diffuser.
Since the purpose of aroma diffusers is usually to make you feel calm and relaxed, it is recommended to place them in the living room, bedroom, or any room in your home where you like to relax. You can place it on the floor or on top of your nightstand depending on its size. Just be sure that it is safe from getting knocked over especially if it contains water.
Another thing that you can consider when thinking of where to put your diffuser is to know which rooms in your home need it the most. Are there rooms where you might want to mask certain unpleasant scents? Rooms that are too dry and would benefit from more humidity? It is important to ask these questions as well to maximize your newly-purchased aroma diffuser.
