Tea infusers are a great addition to any tea set. They are used to steep loose tea leaves and herbs in hot water. Infusers come in different shapes and sizes, and are made of different materials like metal, silicone, or glass. Some popular synonyms for tea infusers include tea strainers, tea filters, tea balls, and tea steepers. Tea strainers are usually made of fine mesh and sit atop a teapot or cup. Tea filters can be made of paper or fabric and are disposable or reusable. Tea balls are metal balls with holes and are easy to use and clean. Tea steepers are made of glass and allow for a clear view of the tea as it steeps. Whatever type of tea infuser you choose, it's sure to enhance your tea-drinking experience.
