COFFEE ESSENTIALS Filter System III (15 x 5.5) 500/pack

COFFEE ESSENTIALS System III Commercial Coffee Filters (15" x 5.5", 500/Pack) are heavy-duty, high-capacity industrial filters designed explicitly for heavy-volume 1.5-gallon satellite and airpot brewing systems. Sourced through Hotel Depot, these filters serve as an exact, high-reliability commercial alternative to BUNN OEM Part #20120.0000 and are fully optimized to fit deep-set 1.5-gallon extraction funnels.

When managing high-volume hospitality, banquet, or convention coffee services, standard 12-cup filters lack the physical volume to safely contain large-scale extractions. Attempting to brew 1.5 gallons of coffee in a smaller filter causes high-output digital spray heads to submerge the coffee grounds completely. This creates massive water surges that spill over the edges, pushing loose coffee grounds directly into satellite servers or airpots and ruining the entire batch.

The System III filters resolve this by featuring an expanded 5.5-inch bottom disk footprint paired with deep, 4.875-inch fluted side walls. This massive, deep-pocket pocket geometry provides ample head space for water expansion, ensuring large-batch extractions run smoothly with zero overflow and zero bypass.

Key Features & Operational Benefits

1. High-Tensile Structural Fluting

The side walls are manufactured with heavy, structured mechanical ribbing. This fluted engineering ensures that when the filter element is subjected to a heavy, turbulent water weight load, the walls maintain their shape and stand perfectly flush against the brew basket. This prevents the filter paper from sagging or collapsing inward, keeping bypass water from slipping down the sides unextracted.

2. Oxygen-Purified, Flavor-Neutral Composition

Pure Profile Preservation: The porous crepe paper is whitened using an advanced oxygen-purified process that is 100% Elemental Chlorine-Free (ECF). This clean manufacturing process ensures the filter leaves no chemical paper tastes or background odors behind, letting the natural roast profiles and delicate estate coffee notes shine through.

Industrial Wet Strength: Formulated from a heavy basis-weight paper stock that holds up to prolonged exposure to near-boiling water ($200^\circ\text{F}+$ / $93^\circ\text{C}+$), eliminating structural splits or blowouts under high pressure.

3. Dual-Layer Hygiene Shielding

Commercial coffee filter paper is highly porous and naturally picks up ambient aromas and moisture from its environment. To safeguard your stock, each bundle of 500 filters is sealed inside a heavy-gauge poly sleeve to repel moisture, back-of-house kitchen grease, and humidity. Stowed inside a clean inner carton, this double-barrier design keeps your back-of-house backup inventory perfectly dry, sanitary, and ready for high-volume service.
