Bruer Spectrum U-Shape Paper Filter #4 - 100pk

Engineered for specialty coffee, the Bruer Spectrum U-Shape Paper Filter #4 features an advanced, multi-layer fibre structure that ensures even water flow and prevents clogging. Manufactured to a precise 0.02mm thickness tolerance, these chlorine-free filters eliminate the need for pre-wetting while leaving zero chemical residue. Designed with a 50mm base and 115mm height for 4-cup capacities, they offer seamless compatibility with flat-bottom drippers like the Moccamaster, Melitta, Bonavita, and Clever.
