Ways to scent a room with essential and fragrance oils: tealight oil burners in ceramic, soapstone, sandstone and mango wood, electric aroma diffusers, and diffuser necklaces and car diffuser kits.
An oil burner uses a tealight to warm a dish of water and oil. An electric diffuser turns water and oil into a fine mist, often with a colour-changing light and a timer. Nebulisers work without water.
Fill the dish with water, add a few drops of oil and light a tealight underneath. Top up the water as it evaporates and never let the dish boil dry.
Diffuser necklaces and car kits hold a drop of oil on a pad or stone, so you can take a favourite scent with you.
Never leave a lit burner unattended, and keep burners and diffusers away from children, pets and anything flammable. Follow the instructions supplied with electric diffusers.
