Oil diffusers that are meant for therapeutic use are much more expensive than what you probably need to use on a daily basis. I just bought a therapeutic grade oil diffuser which consists of a fish pump and a glass bulb. The idea is the oil is pushed through the tube so that it is cold diffused through the air. The effect of this is very pungent and I don’t run it for too long because it is almost too effective! It fills my 800 square foot space with aroma so strong that I have to open a few windows.

  

The cheapest thing to do is simply put a few drops of oil on a tissue and tuck it beside your pillow. This is good if you are using lavender oil to try to get to sleep or eucalyptus oil to heal chest congestion.

  

Another cheap method of diffusing oils is to simply put a few drops in a vaporizer and let the essential oils be diffused through the air in the molecules of water.

  

Just as another word of warning, remember to keep animals away from diffusers or vaporizers as they have less tolerance for aromatics which build up in their bodies and make them ill.

  

Peace Be Still Sam.
