How to Choose a Diffuser

The ideal diffuser for your needs will depend on various factors, including whether you’re looking for a combination of style and practicality or just performance. There are numerous great options out there, each with its own benefits to offer. If you’re struggling to find the right solution, consider looking at some of the following points.

Design

The aesthetic appeal of your diffuser can make a huge difference to your home décor. You might want something sleek and modern or a device with a more traditional vibe. When looking at the design, you may also consider whether your product has colour-changing lights or brightness level options.

Don’t forget to think about the size of the item too. A larger product may have more capacity and last longer, while a smaller device will fit in compact spaces.

Functionality

Diffusers often work as a source of aromatherapy and a humidifier simultaneously. The right solution for you might also come with several additional features, such as a night light or timer settings.

Others might include using your device as a standalone lamp or setting up light shows with a colour-changing cycle.

Ease of Use

Most of the more appealing diffusers today offer very simple functionality. You may be able to adjust settings at the touch of a button, or you could use an app to manage everything. Some appliances have remote controls so you can change modes from a distance, and there are even options with voice control.

Whichever diffuser you choose, prioritise something you can set up quickly, clean with minimal stress, and maintain easily.

Noise Level

If you’ll be using your device while watching television or sleeping, the last thing you want is to hear the sound of a fan whirring in the background. With this in mind, it’s worth checking the product description to determine how loud it can get.

A whisper-quiet performance based on the right technology should mean you can sleep all night.

Safety

Most diffusers are designed to be as safe as possible, but some focus more on peace of mind. You may want to look for products made with toxic-free components if you’re placing the device in a child’s room. It’s also important to determine whether the item uses heat to create steam, as this can come with a risk of burning.

Look for an automatic switch-off function where possible. This will help prevent the product from continuing to operate when it runs out of water and can reduce safety risks.

Summary

We picked the ASAKUKI Smart diffuser as our Editor’s choice. This product boasts many powerful features, such as the ability to control everything via an app. There’s even connectivity with Alexa and Google Home. A 500ml capacity means it continues to run for as long as possible, and there are also various modes and lighting options to choose from.
