Diffusers are essential in maintaining the air quality in enclosed spaces. They come in many different forms, offered in various materials and styles to fit anyone's needs and preferences. Some synonyms to describe diffusers are air fresheners, air purifiers, aromatherapy diffusers, oil diffusers, and scent diffusers. Air fresheners are fragrances in spray, plug-in, or timer form that mask unwanted odours. Air purifiers act as filtration systems, trapping dust and allergens from the air. Aromatherapy diffusers disperse essential oils for a relaxing mood. Oil diffusers, on the other hand, gently heat essential or scented oils to spread a lovely aroma throughout the space. Lastly, scent diffusers use fans to dissipate fragrant oils.
