12 Best Diffusers, Tried and Tested by a Home Scent Obsessive
Most diffusers are refillable, which helps reduce waste associated with home scenting. In this review, I share my favourites, explaining why each one is worth considering for your home. Diffusers vary greatly in design—I even tested a disco ball-shaped model—but they generally fall into two main types: reed and electric.
Understanding Diffuser Types
Reed diffusers use rattan or bamboo sticks to absorb fragrance oil from a bottle, dispersing scent steadily into the room. It is advisable to turn the reeds weekly to maintain the fragrance. Electric diffusers, on the other hand, gently heat a mixture of oil and water, causing it to evaporate into the air. Additionally, there are nebulising diffusers that employ an atomiser to release fine particles of essential oils, offering a stronger, waterless fragrance.
Some diffusers utilise perfume-style scents, while others incorporate pure essential oils like lavender, lemon, and sandalwood, which can influence mood by promoting relaxation or focus. In rating these diffusers, I considered both personal preferences and objective criteria such as potency and how long the fragrance lingered in a room. My top pick is the M&S apothecary restore reed diffuser, praised for its spa-like, non-overpowering scent.

How I Tested
I tested every diffuser in my own home over several weeks. For reed diffusers, I allowed the reeds to absorb the oil for 24 hours before turning them. I moved each diffuser between my kitchen and bathroom to assess its effectiveness at neutralising odours, and also used them in my living room to evaluate the scent's noticeability and whether it felt overpowering. Key factors considered included the scent profile, longevity, refill pricing, and ease of use.
