Studies have shown that certain smells make us feel good and can enhance our lives. Filling our homes with scents we love can make us more productive and relaxed. It’s another way to have our home be a reflection of what we love.

There are many ways to spread scents across our home. But, what type of scent diffuser is right for you? Keep reading, and we’ll help you pick a scent diffuser perfect for your home.

Why You Should Add a Diffuser to Your Home

Many people love diffusers because of the positive effects of essential oils. Diffusers transform the oil into a mist that is easy to breathe. Oils are also made of natural materials, so you can have a great smelling home without using synthetic air fresheners.

For pet owners, essential oil diffusers are great for covering that hard-to-remove pet smell. And, there are essential oils available that are safe for pets.

For dogs, myrrh, rosemary, ginger, lavender oil, chamomile, and frankincense are safe to use. Frankincense, lavender oil, and chamomile are safe to use around cats. We recommend talking to an aromatherapy specialist when picking out oils for homes with pets.

Types of Diffusers

There are four main types of diffusers that you can use in your home. Once you understand what each diffuser type can do, you can find the perfect one for your home.


Ultrasonic diffusers use water and electricity to create mist. The water dilutes essential oils and electricity makes the molecules smaller. Because it’s so broken down, it prevents oil from building up on surfaces.

These diffusers are great if you need extra moisture in the air. If you have a cold, extra moisture in the air can help your sinuses.

Ultrasonic diffusers are ideal for large rooms. You need to clean them regularly to keep all the parts functioning. The price of these diffusers range, but are on the more affordable end.


Nebulizing diffusers are perfect for aromatherapy needs. They are the highest quality option because it has no plastic parts. There is no heat involved.

Instead, pressure vacuums blow air across a tube that releases oil into the air. These oils are pure and not diluted, which is why they work for aromatherapy.

The AromaTech air stream single is a perfect example of a nebulizing diffuser. This system connects to your HVAC and can add scents to any room. It covers up to 7,000 square feet of space, making it perfect for both homes and businesses.


Evaporative diffusers change essential oils from a liquid into a gas. There are small fans in the diffuser that promotes evaporation. This option is noisier because of the fans inside.

The oils break down before they leave the machine, so the scents are lighter than with other diffusers. Because the scent is so broken down, evaporating diffusers work best in small spaces. Some versions of this diffuser are even portable!


Heated diffusers use heat to release essential oils. Traditionally made of clay, they can work with thicker oils that don’t work with other diffuser types. Higher temperatures will create stronger smells and need little effort to set up.

Some heat diffusers use electricity. But, they can also use a candle. Heat diffusers use less oil when the diffusion process takes place, so your oil supplies will last longer.
