This Bunn 12 3/4" x 5 1/4" system II tea filter is the ideal addition to iced tea brewing stations where a Bunn tea brewer is present. It's designed to resist disintegration and keep tea leaves out of your iced tea, while preserving the freshness and flavor of your most popular brews. BUNN filters are uniquely designed for strength so the sides are taller, and you don't end up with overflow and in your drink.
