What is the difference between a tea infuser and a tea strainer?

A tea infuser is a container with small holes that lets you put tea inside and submerge it in water to steep. A tea strainer is a cup-shaped instrument with small holes that rests over a cup. Fill it with tea and pour hot water through to brew your tea. Tea infusers are better for teas that need a longer steeping time, while tea strainers are better for teas that need a shorter steeping time. Shop an array of tea infusers and strainers on 1stDibs.
