There are a lot of essential oil diffusers available online. In fact, there are more than 32,000 essential oil diffusers available on Amazon alone. With so many products to choose from, narrowing the field to a few finalists can feel overwhelming. That’s why it’s important to filter for only the best quality and best value diffusers.
First, you want to determine the size of the room you want your diffuser to effectively cover. Most (high-quality) diffusers include an estimated room size they are most effective in.
Since “too much” diffusing is not a common problem with essential oil diffusers, and since many diffusers offer a way to reduce output if necessary, you should be much more interested in which diffusers provide sufficient coverage.
It’s also important to look at the water capacity of a diffuser, along with the estimated operating time. The operating time informs you of how long you can expect the essential oil scent to last in the room, while you can estimate the amount of water (and oil) diffused by taking the water capacity and dividing it by the operating time (e.g. 100ml and 2 hours would mean 50ml diffused per hour).
It’s also important to take into consideration the build quality of the diffuser you buy. Essential oils can be corrosive to some plastics, which means that a cheaply-made diffuser might break down after only a few months of use. All high-quality diffusers use polypropylene, or another strengthened polymer or material, to ensure the longevity of the product.
Ease of use is another important consideration. This includes both setup (which should involve little more than putting water and your preferred essential oil into the diffuser) and clean up.
The size, or dimensions of a diffuser might not matter to everyone. However, for those with limited space, it might be worth looking into a diffuser with a smaller footprint. Similarly, a noisy diffuser can be distracting in an otherwise-quiet setting — such as a yoga studio or even your bedroom.
Features such as a timer and ambient lighting can be a nice touch, and are worth taking into consideration when comparing one diffuser to another.
