Performance and use

Using this diffuser is straightforward and easy. To use the Amir 100ml Ultrasonic Aroma Diffuser you simply fill it with water and optionally a couple of drops of an essential oil. It doesn’t come with any essential oils included, so you will have to buy them separately.

This diffuser has a lamp which can be set to a single colour or set to switch between 7 different colours, which is great for kids’ rooms as it doubles up as a nightlight. You can also turn the lamp off altogether.

This product is designed to be safe to use. The power adapter complies with RoHS electrical safety regulations and has been certified as being safe for commercial and home use. There’s also an auto shut-off feature that turns the diffuser off when the water runs out. This means you can leave it on overnight without having to worry about switching it off. For safety reasons you’re not advised to use this diffuser in wet places like the bathroom.

This diffuser is small (20 cm tall and 10 cm wide) and only has a 100 ml water tank, so it’s better for small rooms like bedrooms rather than living rooms. It’s effective at humidifying small rooms like children’s and babies’ bedrooms. This diffuser can help relieve stress, alleviate cold symptoms such as congestion, and also prevent dry skin.

The Amir 100ml Ultrasonic Aroma Diffuser will run for around 3-4 hours before the water tank runs out. If you want it to run for longer you can set it to a “30 seconds on, 30 seconds off” cycle, which doubles the amount of time it runs for.

It runs very quietly and shouldn’t keep you awake at night. The manufacturer says it is quieter than 35 dB, which is about the volume of someone whispering.

Pros and cons

  • Quiet
  • Coloured lamp is relaxing
  • Inexpensive
  • Too small for big rooms
  • Unlikely to last a long time


The Amir 100ml Ultrasonic Aroma Diffuser is ideal for putting in a child’s bedroom to help ease cold or hay fever symptoms. It offers great value for money and performs well in small rooms.

This is a cheap diffuser, so you can’t expect it to last forever. Many buyers have found that it stopped working properly after about 6 months. If you want something more durable and reliable you will probably need to increase your budget.


If you want something with a larger water tank, you should consider the VicTsing Aroma Diffuser, which has a 300 ml water tank, which is three times bigger than the Amir’s 100 ml tank. This diffuser can run for around 10 hours compared to the 3-4 hours offered by the Amir diffuser.

Another good alternative is the Pro Breeze Ultrasonic Aroma Diffuser. Like the Amir 100ml Ultrasonic Aroma Diffuser, it has a 100 ml capacity and a lamp with 7 colours. One extra feature with this diffuser is that it lets you set a timer so you have more control over how long the diffuser runs for.
