18x30x1 Koch Multi-Pleat XL11 MERV 11 Filters

Introducing the Koch Multi-Pleat XL11 MERV 11 filters, a superior choice for those seeking top-tier air filtration solutions. These high-capacity filters are designed to provide an unparalleled level of performance, making them an excellent upgrade from standard pleated filters. With their MERV 11 efficiency rating, these filters effectively trap particles as small as 1.0 microns, ensuring cleaner air in your home or workspace. The Koch Multi-Pleat XL11 filters are constructed with a dual-layered media, offering enhanced efficiency and durability.

Product Properties and Specifications

The Koch Multi-Pleat XL11 filters are engineered with a specialized dual-layered 100% synthetic media, developed by Koch Filter for extended surface air filters. This innovative construction includes an upstream electrostatically enhanced layer (E-layer) and a downstream mechanical layer (M-layer), which work together to maintain efficiency over time. The E-layer provides initial electrostatic efficiency, while the M-layer takes over as the filter becomes loaded with dust, ensuring a consistent performance. These filters also feature a low pressure drop, allowing for increased air flow without sacrificing filtration efficiency. With a dust holding capacity that is 30% higher than standard filters, the Koch Multi-Pleat XL11 filters offer extended filter life and reduced maintenance requirements.

Practical Uses and Benefits

Whether you're looking to improve air quality in your home, office, or commercial space, the Koch Multi-Pleat XL11 filters are the ideal solution. These filters are particularly well-suited for environments where high air quality is essential, such as hospitals, laboratories, and pharmaceutical facilities. Their superior efficiency makes them an excellent upgrade from disposable filters and ordinary pleated filters, providing cleaner air and a healthier indoor environment. With their extended filter life and reduced maintenance needs, the Koch Multi-Pleat XL11 filters are a practical and cost-effective choice for any filtration system.
