  1. Do you use diffusers just to enhance the smell in the room or are they effective in promoting healing if you are using a diffuser? Another thing I was wondering is if it is safe to use around pets. I think I read somewhere that candles can be harmful to pets when their release their aroma. (I can’t remember if it was the wax or the scents that were used.)

    Great post. I loved seeing the different varieties of diffusers.

    1. Hi Melinda,

      Diffusing essential oils also helps to purify the air, killing bacteria and supporting the immune system. If you are using an ultrasonic diffuser – it ionizes the air releasing negative ions that basically combat the dust and allergens (positive ions). Also ultrasonic diffusers act as a humidifier to bring moisture to the surrounding air.

  2. Thanks for the information Anna! You’ve just given me some great gift ideas for Mother’s Day, Birthdays, and Christmas! I’ll be sure to refer back to this post for reference before purchasing. There are a few diffusers you listed that I think would go over well with my loved ones. I’ve got you bookmarked! 🙂

  3. So glad I came across your article. I’ve been thinking of getting an ultrasonic diffuser for a while and reading this has pushed me to consider it more. I love the designs of all these especially VicTsing model. Plus the fact they are all BPA free makes them more ideal to be in the home.

    I also like that there is one for kids too as my son has eczema and having one of these will hopefully help with his dry skin. Can you recommend any good essential oils to go with these? Also, can these items be shipped to UK?

    Thanks for a thorough and informative read. Will definitely bookmark!

    1. Hi Teresa!

      Yes, I have a couple diffusers myself – and they are great! i’m thinking to get one thats bigger/holds more too.

      I think having an ultrasonic diffuser for your son would definitely help his skin, with more moisture etc in the air..
      Here is a link on some extra info on some essential oils that can be used for eczema:

      The VicTing model that you like is also available in the UK – if you use the link i provided it should direct you to the UK side of amazon..

      I usually get my essential oils from, but recently ordered some from They are both decent quality at an affordable price. Also I have provided some ads on my site for barefut oils that are also decent.

      Glad the article helped you out!

  4. I live in a tropical warm climate city and would like to know if diffusers would still have the same effects here?

    My son has a condition where he is allergic to dust and I have tried almost all devises to help him have a peaceful night’s sleep. Would like to explore using diffusers and your article provides the valuable information to make this decision.

    1. Hi there, 

      I think with your climate, you probably may not need much more humidity (since ultrasonic diffusers also act as humidifiers) although ultrasonic diffusers also ionize the air with essential oils, cleaning and freshening it up, getting rid up pollutants – so these diffusers may be something to try out!
