Features

  • High-Efficiency Headered Design: Engineered for 4-inch systems, the Opti-Pac Durable PH delivers high MERV-A performance in a compact footprint. Its headered construction allows easy installation in existing frames while maximizing dust capture, reducing changeouts, and improving indoor air quality across a wide range of HVAC environments.
  • Built for Strength and Stability: A rugged plastic enclosing frame supports the filter pack through its full service life—even under extreme airflow or pressure. The synthetic media is permanently bonded to the frame to prevent bypass, while thermoplastic separators maintain pleat integrity for consistent, reliable performance.
  • Maximized Media Exposure: Close-Pleat configuration ensures uniform airflow through the entire media surface. This design increases dust-holding capacity, minimizes resistance, and extends filter life—delivering performance and cost savings in commercial, healthcare, and industrial applications where uptime and efficiency matter.
  • Certified Durability and Performance: Withstanding up to 10.0" of water gauge pressure, the Durable PH is one of the toughest filters in its class. Its synthetic construction is resistant to moisture and microbial growth, fully incinerable, and carries an ECI1 3-star rating—making it a reliable, sustainable solution for high-performance filtration systems.
