Picking the first one you see can be tempting when all you want is to bask in the aromas of essential oils all day. But did you know there are a lot of things to think about before purchasing? Keep reading to know more about essential oil diffusers.

Humidifiers vs. Diffusers

Some people think humidifiers and diffusers are the same but they are actually completely different. While diffusers function to disperse essential oils into the air, humidifiers add moisture to the air and are often used in dry places. Humidifiers have become popular household staples but excessive humidity lessens health benefits contained in essential oils. Diffusers make very fine mist to transport oils’ vital elements. Dry air can clog your nose so diffusers can actually help unclog it.

Diffusers are a great way to circulate essential oils to the air you breathe so whatever benefits you reap from using a diffuser are actually from the essential oils you use.

  • Purifies air
  • Removes dust
  • Gets rid of stress
  • Improves immunity
  • Makes room fragrant
  • Humidifies
  • Removes bad smells
  • Maintains essential oils’ purity
