HAF-BE & HAF-G MESP® Energy-Saving HVAC Air Filters
The HAF-BE and HAF-G Series are high-performance, in-duct MESP® (Micro-Electrostatic Precipitation) air filtration solutions engineered for commercial and institutional HVAC systems. While both series share the same core MESP® technology, they are purpose-built for different air-handling applications, ensuring optimal performance across both recirculated and 100% outdoor air systems.
The HAF-BE Series is designed for standard Air Handling
Units (AHUs) serving recirculated and mixed-air systems, replacing disposable
media filters with a long-life, energy-saving electronic solution.
The HAF-G Series is specifically engineered for DOAS
(Dedicated Outdoor Air Systems) and MAU (Make-Up Air Units), where high volumes
of untreated outdoor air, variable humidity, and seasonal contamination require
enhanced robustness and stability.
Together, the HAF-BE and HAF-G Series deliver medical-grade air purification (MERV 14–16 equivalent) with ultra-low pressure drop, enabling substantial energy savings, improved indoor air quality, and measurable sustainability benefits.
