MERV 11 Pleat Rigid Cell Filters
  • MERV 11 rated per ASHRAE test standard 52.2 and exceeds the LEED standard.
  • Sustainable Component for a LEED/Green Building Initiative.
  • Proprietary media provides ultra-low pressure drop to relieve strain on motors and reduce energy costs.
  • Available with or without header.
  • High efficiency and low pressure drop make them great replacements for 4" minipleats, traditional 6” and 12" deep rigid cell filters, and 4 and 6 panel V-cells.
  • Durable frame and media resists moisture, does not support microbial growth, and stands up to turbulence and abrasion of high air flow for a longer life.
  • Provides a high dust holding capacity and stores easily.
  • Ideal for commercial and industrial applications.
  • Not designed for high velocity turbine applications.
  • Available in plastic or galvanized frame.
  • Non-standard size filters available upon request. Please call for pricing.
  • Frame customization available for additional fees.
