To put it simply, an oil diffuser is a device that breaks essential oils down into smaller molecules, dispersing them into the air for a pleasant or calming effect—depending on the oil that’s been put into the diffuser. Different essential oils have different claims—for example, lavender is meant to support sleep.1 The diffuser’s job is to evenly disperse the particles at a comfortable concentration that’s easy to breathe and doesn’t overbear the room.

Plain and simple, a diffuser is used to fill the air in a room with tiny, breathable particles of beneficial essential oils giving the room a calmer, more pleasant-smelling ambiance. It’s well known that scent is associated strongly with memory. When I diffuse lemongrass oil it reminds me of Thailand, my happy place, and I instantly feel a vacation-level chill come over me. Oils just set a tone for your space and the activity you’re performing that day.”

Types

There are four main types of oil diffusers on the market right now. You can choose your diffuser based on the intensity of the effect desired, and of course, the limitations of your space.

Nebulizing Diffusers: These diffusers work by using pressurized air to diffuse a mist of oil. A vacuum pulls oil to the surface of a distribution tube resulting in a burst of aroma into the air. Nebulizing diffusers don’t require water or heat, which makes them a low-maintenance choice. These are plastic-free for the eco-conscious user.
Ultrasonic or Humidifying Diffusers: Ultrasonic vibrations break up oil molecules to create a fine mist. You will need to dilute the essential oil with water for the diffuser’s electronic frequencies to release the oil into a mist. Ultrasonic diffusers work like cold humidifiers, which makes them a great choice if you want to add moisture to the air, especially during cold season. The plastic ultrasonic parts require cleaning as oils can be corrosive to plastic.
Evaporative Diffusers: In this type of diffuser, a small fan helps turn oil into gas, making oil evaporate into the air. However, as the oil evaporates, it loses some of its potency. So, this is a good choice for people who want a quick, occasional aromatic sensation.
Heat or Electric Diffusers: Instead of using a fan to turn oil to gas, a heat diffuser uses heat, most commonly, electric. Heating oil may change its chemical properties making the oil less or more intense depending on its properties. Because there’s no fan involved, these diffusers are silent. Different types of heat diffusers include candle diffusers, electric heat diffusers, and lamp ring diffusers.

There are also some tricked-out oil diffusers on the market with cool features like ambient lighting and sound features. Design-led ceramic or reed oil diffusers give your space a wellness vibe, whether you opt for a minimalist or hygge aesthetic. Oil diffusers with automatic switch-offs or timers are a good choice if you plan to use your diffuser for extended periods or to fall asleep.

5 Advantages of Purchasing and Use

Get Rid of Bad Odor

No one wants to live in a stinky home. Imagine having guests over, and they comment on the stench of your home, that would be so embarrassing. With essential oil diffusers, you can pick a scent of your choice and have that smell permeate into your home. This will give your home the nice, fresh smell you always wanted. Essential oil diffusers can even work to clean and purify the air around you without the need for chemical sprays.

Get the Sleep You Deserve

Don’t you wish for a relaxing and soothing sleep after a long day at work? Well, you can achieve that very easily with the help of the Best Diffuser. Diffused oil helps people of all ages relax and get a peaceful sleep. Furthermore, diffusers also make a gentle hum sound that works to relax your mind and pacify you. We recommend you use Lavender, Chamomile, Bergamot, Jasmine, Rose, and Sandalwood to help you relax and get good sleep.

Relieve Pain & Gain Energy

Don’t we all hate the feeling of pain? Did you know that essential oils can help relieve pain? Essential oils to relieve headaches are lavender, peppermint, eucalyptus, and rosemary. If you suffer from heartburn, menstrual pain or respiratory disorders then oregano is a good option for you. Sandalwood helps to relieve symptoms of a sore throat. Furthermore, essential oils activate your brain cells, so you don’t feel so sluggish.

Safer than Candles

Did you know that diffusers are safer than candles? Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, and they don’t emit harmful chemicals in the air. You can expect that electronic diffusers won’t pose the risk of fires that candles would. Many scented candles contain toxic chemicals, such as toluene and benzene. An overdose of these toxins can cause respiratory troubles or worse in extreme circumstances. Some candle wicks are made of lead which can release carcinogenic particles in the air.

Mosquito Repellent

Mosquitos can cause an array of illnesses like Malaria, Dengue, Zika fever, and more. It is very important to make sure you rid your home of mosquitos and other pests so that you don’t become a victim of such lethal diseases. However, scientists have shown that oil diffusers can be safely used to rid mosquitos. Imagine what trouble you can save yourself from if you purchase a small diffuser for your home. There would be no costly trips to the doctor.
