PFS® Pre-Filters

PFS® Pre-Filters are comprised of synthetic nonwoven substrates, treated with proprietary fine and nanofibers to increase capturing efficiency of smaller size ranges of particles.

Typically installed upstream of high efficiency barrier filters, the right prefilter will trap a higher percentage of fine and coarse particles prolonging the life of the final filter.  

Construction includes wire backed and glue bead supported pleated structures to stabilize pleat uniformity and maximize flow and dust loading capacity.

  • PFS-4™ – MERV 8 and MERV 11 filters with high capacity, wire supported pleat design with fine fiber treatment 
  • Premier-Pleat™ – MERV 13 filters with high capacity, glue bead supported pleated design with nanofiber treatment


All PFS® Pre-Filters are provided in standard 2” and 4” depths. Custom sizes and depth are available upon request.
