Specialty 6 Cup Teapot Filter by Price & Kensington. Made entirely of high-quality stainless steel, the teapot filter lasts and lasts, cup after cup – and as it’s designed, you get only the best quality brew from day one. To better make use of the internal environment of the teapot, the locking mechanism and fine mesh of the filter allow loose leaf tea to thoroughly infuse itself with the hot water. For a quick cleaning, just place the filter in your dishwasher or scrub and wipe with a washcloth.
