102-499-006 - Multi-Pleat XL11 MERV 11 Extended Surface Pleated Panel Filter, 16x20x1, Standard Capacity

The Multi-Pleat XL11 is a medium-efficiency, extended-surface pleated panel filter built to exceed the initial efficiency and overall performance of standard pleated filters. It is rated MERV 11 under ASHRAE Test Standard 52.2, with an initial dust-spot efficiency around 45% and an average dust-spot efficiency in the 55-60% range under ASHRAE Test Standard 52.1, making it a meaningful upgrade from disposable and ordinary pleated filters in hospitals, laboratories, pharmaceutical plants, commercial offices, and other settings that need cleaner air.

Construction

XL11 media is a dual-layer, 100% synthetic construction developed by Koch Filter: an upstream electrostatically enhanced layer (E-Layer) paired with a downstream mechanical layer (M-Layer). Single-layer electrostatic filters tend to lose efficiency as their charge dissipates over time; the XL11's dual-layer design addresses that weakness, since the M-Layer keeps performing mechanically as the E-Layer's electrostatic effect fades, maintaining strong efficiency and dust-holding capacity.

Capacity Level: Standard Capacity

The standard-capacity XL11 balances efficiency, economy and performance for systems on preventive-maintenance schedules. Packaged 12 per case and made in the USA.
