The Tupkee 12-Cup High-Quality Industrial Commercial Large Coffee Filters are perfect for coffee lovers who believe a great cup starts with the right filter. Designed for use with 12-cup commercial drip and airpot coffee brewers, these filters are fully compatible with Wilbur Curtis, Fetco, Bloomfield, and Bunn coffee makers. Crafted from premium heavy-weight, special-grade paper, they ensure proper water flow through the coffee grounds while preventing any grounds from seeping into your brew. The taller-walled design provides added durability and prevents collapsing or overflow, keeping your brewing process clean and efficient. Tupkee filters are also chlorine-free and bleached using an oxygen-based, elemental chlorine-free (ECF) process, ensuring no detectable levels of dioxin while maintaining a clean, natural coffee flavor. Measuring 9-3/4 inches in diameter when flat and 4-1/4 inches at the base, these filters are built for consistent performance in high-volume settings. Proudly made in the USA and backed by Tupkee’s unconditional satisfaction guarantee, this pack of 1000 filters delivers reliability, purity, and the perfect extraction for a richer, more flavorful cup of coffee every time.
