The HAF-G Series MESP® HVAC air filters are purpose-built for DOAS (Dedicated Outdoor Air Systems) and MAU (Make-Up Air Units) that condition 100% outdoor air. Designed to operate reliably under high airflow, variable humidity, and elevated contaminant loads, the HAF-G Series delivers high-efficiency air purification with ultra-low pressure drop, enabling significant energy savings in demanding ventilation applications.

Using patented Micro-Electrostatic Precipitation (MESP®) technology, HAF-G filters provide MERV 14–16 equivalent performance without disposable media, ozone generation, or secondary pollutants. The washable, long-life design reduces operating costs, minimizes maintenance, and supports sustainability and ESG initiatives across commercial, healthcare, hospitality, and institutional facilities.

Key Benefits

  • Optimized for 100% Outdoor Air - Engineered specifically for DOAS and MAU systems handling high ventilation rates and humidity.
  • Energy-Saving Performance - Ultra-low pressure drop reduces fan energy consumption by 65%.
  • High-Efficiency, Ozone-Free Filtration - Effectively removes PM2.5 and particulates while deactivating viruses and bacteria—without harmful byproducts.
  • Long-Life, Washable Design - 10+ year service life with no disposable filters, lowering TCO and landfill waste.
