Here Are The Top 5 Aromatherapy Diffusers in the UK

Scent is our most powerful sense! It is estimated to control approximately three-quarters of the emotions we experience on a daily basis, yet so many people underestimate its importance. 

The candle industry capitalizes on this fact and makes almost 2 billion dollars from Brits each year! But did you know that artificially scented items like candles can cause respiratory illness, allergies, asthma attacks, and even cancer? 

This is one of the many reasons a new fragrance device called an aromatherapy diffuser has been taking the world by storm. 

What are aromatherapy diffusers?

Aromatherapy diffusers use 100% naturally derived essential oils to create pleasant and healing aromas

In recent years, they have become increasingly popular, and it’s easy to see why: 

  1. 100% natural, non-toxic and chemical-free. Aromatherapy diffusers use naturally derived and safe oils to fill your home with a gentle aroma. That means no respiratory infections, asthma attacks, or carcinogens!
  2. Great for sleep. Certain types of essential oils have been shown to be great sleep aids. They can increase relaxation and sleep quality considerably!
  3. Amazing health benefits. Each essential oil has unique properties that can benefit respiratory health and mental wellbeing! Talk about scents with benefits!
  4. Wonderful, customisable scents. The nature of aromatherapy diffusers allows you to adjust the scent they give off more than any traditional scented product.
  5. Environmentally friendly. Diffusers release absolutely no VOCs–the harmful chemicals given off by cand

#1 Kalmkoala Aromatherapy Diffuser

At the time of writing this article, Kalmkoala was having a deal on their diffusers. Buy 1 kalm diffuser and get 6 FREE essential oils. 

Kalmkoala is a trusted UK-based brand that specializes in therapeutic home comfort products. Their new Aromatherapy Diffuser is a cutting-edge, luxury option that is currently deeply discounted during a site-wide sale

Aside from having the longest run time of any diffuser on this list, the sale price also makes it the most affordable option (although the regular price is the most expensive, so get the sale price while you can!)


  • Impressive features. We love the customisable run-time (the longest available on this list) and the variety of oils they offer.
  • Affordable luxury. As we said, there is nothing comparable to this quality available at the sale price! Don’t wait and miss out!

2. THE ATOMISER by John Lewis Aromatherapy Associates

At £120, this is the most expensive option on the list. This is because the Atomiser’s technology allows oil to be diffused without the use of water. A few drops of oil are enough to fill your house with scent! 

However, the downside to this is that it can only be used for a maximum of three hours, compared to our #1 choice which can be used for up to 8 hours.

3. Neom Wellbeing Pod

The Wellbeing Pod caught our eye with its night light feature. It costs £95 and, like the Atomiser, can run for a maximum of three hours. However, unlike the Atomiser, it requires water to dispense fragrance. 

The Wellbeing Pod is a great choice for those who like a nightlight while they sleep.

4. The Perfume Genie 2.0 by rituals

The Perfume Genie is the most unique design on our list. Its bronze colour makes it an eye-catching statement piece that would look lovely with certain types of decor.

It is also wifi capable and can be paired with Alexa or Google Home for voice activation, but it is one of the more expensive options on our list at £99.

5. Wooden Bamboo Diffuser by Oliver Bonas

This small diffuser made our list because of its unique bamboo material. We love bamboo for its renewable properties, so if you’re looking for an affordable, renewable option, this is a good choice. 

It has one of the smaller reservoirs of all the diffusers we surveyed but it makes up for it in price. It is the second most affordable at only £59.50.

Tested and loved by many, you can’t go wrong with this diffuser. Here’s what a few of kalmkoala’s happy customers had to say.

Truly Amazing Product! My son has always had anxiety at bedtime and he often takes hours to fall asleep. I bought the Kalm diffuser and used the Tranquillity blend and he falls asleep almost straight away!
Tammy Wry
My home feels like an oasis. I bought 3 diffusers, one for my bedroom, home office, and living room. In my bedroom, I use the Tranquillity oil, in my office I use Energy, and in the living room I sometimes use Refreshing and other times I use Calm. They all smell amazing and the smells don’t clash, so I feel like I’m living in a spa. Its so lovely and I noticed a huge difference in my family’s mood. When guests come through the door, the first thing they say is “whats that amazing smell?” I love my diffuser!
Leigh Ann Knights
Forget Candles!! I stopped using candles in 2018 because of a respiratory infection and the doctor said chemical scents would make it worse, but man I missed my delicious smells. When I saw an ad for the kalm diffuser, I made the decision to go for it and I’ve never looked back!
