What is a humidifier, and should I buy one?

Humidifiers are machines that add moisture to the air. They help increase the air’s moisture and reduce the dryness of a space. Humidifiers are great at treating dryness of the skin, nose, lips, and throat. They can help lessen the symptoms caused by the flu or common cold.
Buy a humidifier if you want to increase your air’s moisture and ease health issues. They help relieve the following health symptoms:
  • dry skin
  • sinus congestion/headache
  • dry throat
  • nose irritation
  • dry cough
  • cracked lips
  • bloody noses
  • irritated vocal cords
Room humidifiers are useful if you want to reduce the symptoms of your illness. They work well at improving the moisture in your air.
They have a bigger water tank compared to essential oil diffusers. Increasing moisture levels in the air is the primary goal of a humidifier. A humidifier has a bigger size compared to ultrasonic diffusers.

Should I Get an Essential Oil Diffuser?

Ultrasonic diffusers are the most common type of essential oil diffuser you can buy. They work similarly to humidifiers. The size is much smaller than a humidifier. The primary purpose of an oil diffuser is to diffuse your essential oils into the air. Ultrasonic diffusers use water mixed in with oils to disperse the air in your space. This helps you inhale your favorite essential oils and reap the health benefits.
You can use a diffuser as a humidifier only in certain instances. There are hybrid diffuser/humidifiers that you can buy to fulfill both benefits. Make sure that you buy one that specifically mentions that combination or else you will not get the full benefits.
Ultrasonic oil diffusers are different that humidifiers in that they have the following benefits:
  • Eliminates Odors
  • Safer Than Candles
  • Promotes a Good Night’s Sleep
  • Encourages A Wakeful Morning
Ultimately, a diffuser works as a humidifier, but at a smaller scale, due to the size of the reservoir. Standard oil diffusers will humidify the immediate space very little. Depending on the size of your room, it will not have any moisturizing effect.
Essential oil diffusers cost between $30 – $100. They are a little more expensive than humidifiers.
