What to Look for in a Smart Diffuser
Here are some of the main things you need to look for when buying a smart diffuser.Size
Diffusers come in different types of shapes and sizes. Some are tiny enough to be kept in cars, while others are made for giant rooms. The difference here will be the amount of water they hold. You can find diffusers that hold as little as 6 ounces of water to those that can hold up to 60 ounces. Narrow things down by taking into account the space you will be using the smart diffuser in, and then choose the appropriate size accordingly.Noise
As smart diffusers get bigger, they generally get louder as well. The whole point of having a smart diffuser in your home, however, is that you can diffuse your favorite scent without worrying about the noise. Desired noise level is also variable because some people like having some white noise in the background when they sleep. Think about how much noise you’re okay with, and pick a diffuser that isn’t noisier than that!Timer options
One of the great things about smart diffusers is that they come with a timer option. This allows you to set a timer, relax, take a bath, or even go to sleep without worrying about turning the diffuser off before the water or oil runs out. Even though this might not seem like that big of a deal, when you’re trying to be mindful and use the aromatherapy to its full potential, having the constant thought in your head that you need to turn the diffuser off will keep you from actually relaxing. So if you don’t like having to turn off the diffuser yourself, make sure that the one you get has a timer function.Functionality and ease of use
Almost all smart diffusers come with an app that makes them a lot easier to use because you can just control them through your phone. Some diffusers even allow you to get really deep into customization, which makes them even easier to use because you can make adjustments to suit your lifestyle fully.Portability
While some diffusers might claim they’re for home use, they might be a little too small, while others can be too large to put anywhere! Not only does that mean you might run into problems trying to fit the smart diffuser in your home, but it might also be too light or too heavy to deal with! Make sure to check the dimensions and weight before making a purchase.Price
Due to rising demand in the market, you can find all sorts of diffusers. Some will be better in terms of quality, and others will have more features. Just because something is more expensive won’t necessarily mean it’ll have the quality or functionality to match. So set a budget, and try something suitable because no matter the budget, there will always be one product that will fall right into your range!
