How to Pick the Best Diffuser

Here are the guidelines to follow when picking the top diffuser:

Choosing the Right Type of Diffuser

There are actually several types of diffusers in the market. The main way that these diffusers differ is in the way that they eject the scent into the air.

Heat-based diffusers are the cheapest options on the market. Here, the diffusers use heat to cause the essential oil and water mixture to evaporate into the air.

While these may have been commonplace once, they have largely gone out of fashion.

This mostly has to do with the fact that the characteristics of the essential oils are often changed when they are heated. As a result, they are less effective.

Not to mention, these diffusers don’t do such a great job of dispersing the fragrance.

Then, there are the ultrasonic diffusers. These currently are the most popular option. Unlike with heat-based diffusers, these machines use frequencies to cause the oil and water to vibrate and turn into smaller molecules. These are then released into the air.

This method ensures that the fundamental elements of the essential oils remain unchanged. These diffusers are often rather simple to use and clean, ensuring that they are low maintenance.

Then, there is the nebulizer diffuser. This vaporizes the essential oils before it is diffused into the air. Thus, it produces a stronger fragrance. However, there are several downsides to this kind of diffuser. For one thing, it is more expensive. For another the diffusers tend to be fragile and can be easily broken.

Consider Safety Features

With electric or nebulizer diffusers, it can be easy to forget to keep an eye on them. Once you add the oil and water and switch it on, it is only natural to turn your attention to other things. However, this is still an electrical device that can malfunction, particularly when it works on empty.

This is why it is a good idea to get a diffuser that has an Auto Shutoff function. With this component, the diffuser will turn itself off when there is no more water or oil left in the reservoir. This can prevent the diffuser from burning itself out or even leading to another issue.

Check the Area Coverage

As you can see, diffusers have multiple ways of getting the scent of essential oils into the air. This means that the size of the oil and water molecules can be different. At the same time, they can also differ in how powerful the ejection of the molecules is.

Due to this, the oil and water moles can disperse at different rates, covering specific distances. Some can cover a large distance, while others have less coverage. Therefore, this is something that you should check on before making your purchase.

If you want a diffuser for a smaller space, then this coverage will not matter as much. On the other hand, if you would live to cover a larger area, then you will need to consider the rate of dispersion.

What Features to Look For

Now let’s take a look at some of the features that you should be looking at with your diffusers:

Reservoir Capacity

The reservoir capacity of diffusers can vary quite a bit. They can be as little as 100ml and as large as 500ml. As such, you need to pick one that is right for your needs. Now, if you only use your diffuser for a short period of time, then a smaller reservoir makes sense. It also gives you the opportunity to change the oil and water more regularly and to keep things fresh.

On the other hand, if you want a diffuser that will work for hours on end, then a larger reservoir capacity makes sense. You just have to fill it up once and the diffuser should be able to work for around 12 or so hours a day. This kind of diffuser is especially useful for open-plan homes, offices, and commercial spaces.


Of course, you may not want your diffuser to work for as long as it possibly can. You may be after a particular fragrance strength or you may want to save power. Regardless, it can be helpful to choose a diffuser that is equipped with a timer.

The most common timer intervals are one hour, 3 hours, and 6 hours. However, this will depend on the make and model of the diffuser. So, select one that is best suited to your requirements.

Low Maintenance

The last thing that you want to do is to fuss around with your diffuser. So, make sure that is low maintenance. First, check that filling the diffuser reservoir is a simple matter. The fewer components or processes that you have to get through to complete this task, the better.

You should also determine how easy it is to clean out the reservoir. Look for a model that doesn’t have smaller components that can get gummed up with regular use. You should be able to rinse out a few pieces and have the diffuser working again in no time at all.

Multi-Purpose Features

While most diffusers have a singular function, this isn’t the case for all of them. There are many makes and models that can be converted to humidifiers and sometimes purifiers as well. If this is something that you are interested in, then this is a function that you should look for.

Aesthetic Appeal

More often than not, diffusers are placed in public or communal areas of your home. As such, the outer design of the diffuser can matter a great deal. Fortunately, most manufacturers appreciate this and have worked to produce more elegant or interesting designs.

You will need to determine the décor of a particular place before selecting the right diffuser design for your home. If you have a more natural or green aesthetic, opt for one with a wood-like exterior. If you have a minimalistic interior, then opt for a more modern design with a sleek cover.

Smart Features

These days, diffusers are Smart too! And, for the most part, these smart features are quite helpful. The manufacturers have an app that you can download on your smartphone and sync with the diffuser. This allows you to program the diffuser from far away.

This is an excellent feature if you want your home to smell nice before you get there. It is also great if you need to prepare for company but aren’t at home yet. Either way that you look at it, this works out well for you. Just make sure that the Smart features are high quality and work as claimed.
