My HAMSWAN Ultrasonic Essential Oil Diffuser Review

Recently I received a HAMSWAN ultrasonic essential oil diffuser to review. I love candles, reed diffusers, oil burners, literally anything that looks pretty and wafts a lovely fragrance around my home. Ironically, I have no sense of smell, but I don’t let that stop me having something pretty and scented in near enough every room of my house. Having never had something quite like this I was intrigued, to say the least. What did I think? Read on for my HAMSWAN Ultrasonic Essential Oil Diffuser Review.

First up it’s really easy to put together. It comes whole and the top unit just slides off to allow you to fill the water tank. Make note of ‘slides off’ when filling and moving hold from the base, not the top. As you can see in my pictures above. It’s not difficult to use and not too many parts to be messing about with. Great for someone like me, who likes easy simple things!

Filling it up is pretty easy too. It comes with its own jug for perfect prep. All it needs is 100ml and you’re ready to go. Plug in and turn on. It goes without saying you should fill up when it’s not plugged in, but just in case, I said it anyway.

Switching it on and off is pretty easy too. With a mist and a light button to control it and switch it on and off on the front. It also has LED lights too that look so pretty in the dark. A little bit mesmerising too and relaxing to look at when it’s doing it’s thing!

You can also pop a few drops of water-soluble essential oils into the water tank to gently infuse the room with your chosen scent too.

How Does it Work?

The diffuser works via the ultrasonic frequency at 2.4MHz to diffuse the water safely into the room. Just fill the tank and add in essential oils if you prefer. Then press the button(s) on the front to turn it on and activate the lights and mist. There are different settings you can use. You can change the colour of the lights to suit your mood.

Have the mist run continuously or at intervals. On continuous use it will run for around 3-5 hours before shutting off. On intervals of 30 seconds on and 30 seconds off it will last for 6-10 hours.

How Does it Look?

I don’t normally go for wooden decorative items personally and I was worried it would look out of place next to my glass and metal ornaments. But it doesn’t. With my furniture being wood it fits in quite well. Initially, I had no idea where it would look best, but after popping it on my bookcase, I think I’ve found it’s home. Plus I love the LED lights too a lovely feature and not too bright and obvious. Just a nice gentle glow.


I actually like it. An understated piece that slots in well in living room. I have been using it on humidifier setting recently. Emitting a constant stream of steam to release moisture into the room. I find it can get a bit dry when I have the heating on a lot. Does anyone remember their grandparent or parents (it was my nan and grandad I remember doing it) putting a bowl of water by the radiator so it didn’t dry the air out too much? Or is that just a family quirk?

I also love that you can use it without fragrance. As I don’t have a sense of smell sometimes I worry about if the fragrance doesn’t smell so good, or if the fact I have a different scent in different rooms makes my house smell like some sort of perfume experiment gone wrong.

My favourite feature though is the self-timer. When it runs out, or after a period of time, it switches off. When the water gets low, it switches off too. If you leave it on continuously like I did, the mist will look a bit like the shadow in the above picture! I have a terrible memory and have been known to forget to turn things off (I once left my Air Wick electric wax melter thingy turned on for 3 days as I can’t smell it I forgot it was on!), so this being able to turn itself off is a great feature for me.

For me, the Hamswan Ultrasonic Essential Oil Diffuser is a nice relaxing diffuser and slots in well next to my ever growing collection! If you like the look of this you can check them out in their Amazon store, current selling price £29.99. But I have a 15% off code for you to use should you choose to purchase.

  1. This looks really good and safer for animals. I always worry with the glass diffusers that my pet may knock it over and get covered in the oils.

  2. Nice. I do like nice scents. I had a poor sense of smell, but found following taking prescribed medication for chronic pain :- Sense of smell has improved, which is a nice benefit. I can now smell flower, bushes etc as I walk past them.
    Essential oils can be soothing, relaxing etc.

  3. That’s interesting. It’s very pretty, and I love the sound of the self-timer! I have the opposite problem in that my place can get a bit damp, but a timer would really help minimise the effects of it, I think.

  4. I love the wooden look of the diffuser, very stylish. I would love to try it with fragrenced oils, would make the house smell lovely.
