The Top 7 Essential Oil Diffusers For Large Rooms Reviewed

essential oil diffuser reviews

Aromatherapy is a form for alternative medicine. It is an inexpensive method of taking care of a number of health issues. It involves the use of essential oils, placed in an oil diffuser to warm the oil and mist it into the air for inhalation.

The essential oils come directly from the plant, giving you all the health benefits of nature. Not all diffusers are created equally, so it’s important to know what to look for when choosing the one you want to use in your home.

Best Essential Oil Diffusers For Large Spaces

1. Advanced Aromatherapy Essential Oil Diffuser by DoTERRA

Advanced Aromatherapy Essential Oil Diffuser by DoTERRA review

This nebulizing essential oil diffuser is the ideal choice for the best therapeutic benefit because it does not use heat or water to diffuse the oils into the air. Timers are built in to keep the diffuser running for short periods of time for maximum benefit and to prevent “nose fatigue” from getting used to the scent of an oil after a while. You’ll also get defense against airborne viruses and bacteria. While it is more expensive than others on our list, it has to do with the quality of the product and the type of diffusing technology.

Types of Diffusers

An ultrasonic diffuser uses electric frequency to create vibrations. These vibrations move to where the oils float, and evaporate the oil so it is diffused into the area without heat. Since heat can break down the oils and interfere with the quality of the oil’s benefits, the ultrasonic diffuser is a good choice. The process also produces negative ions that can help calm the body and surrounding environment.

An evaporative diffuser uses air that blows through a filter and evaporates the oil through it. Since lighter oils will diffuse faster than heavier oils with this method, you may not get the same quality health benefits as you would from the whole oil, but it will still do a decent job of getting the aroma in the room. It runs quietly, too.

A nebulizing diffuser breaks down the oil into super fine tiny drops, and then sprays them into air, to atomize and ionize the oil so you get the maximum therapeutic benefit. This diffuser should be used with thin oils that haven’t been diluted.

Heat diffusers are not ideal for the therapeutic use, because the heat will destroy the quality of the oil. Using this type of diffuser is good for making your room smell good.

Reed diffusers use reed sticks placed in the oil to soak it up and release it into the air. Reeds can hold the scent for months, but the affected area is small, and the scent is light, so they are better used for fragrance, rather than therapeutic purposes.

Candle diffusers use a small candle to heat the oil so it will evaporate and release the aroma. They are much like the ultrasonic diffuser, but do not require electricity to run.

Aromatherapy is not intended to replace professional medical care. It is intended as a complementary therapy. If you have a health condition that does not improve with the use of aromatherapy, seek care from your family doctor or another health care provider as soon as possible.
