AAF Flanders PREpleat LPD MERV 10 Standard Capacity

The PREpleat LPD (Low Pressure Drop) MERV 10 is the most-specified AAF Flanders commercial pleated filter in North America. It's the workhorse standard-capacity 1″ pleated filter for offices, schools, retail, government buildings, and the millions of commercial RTUs and AHUs running standard 1″ filter racks. The LPD construction delivers MERV 10 efficiency at lower pressure drop than competing MERV 10 pleats — meaning lower fan energy and longer service intervals at the same efficiency.

Specifications

  • MERV 10 per ASHRAE 52.2
  • 1″ standard capacity — drop-in replacement for any 1″ commercial rack
  • Low pressure drop construction — engineered media density and pleat geometry minimize static loss
  • Permagrid radial pleat support — extruded plastic backing keeps pleats stable
  • Moisture-resistant beverage-board frame
  • UL 900 Classified
  • Section 889/NDAA compliant

Why LPD Dominates Commercial Spec

In commercial HVAC, fan energy is the dominant operating cost. Pleated filters add static pressure to the system; the higher the pressure drop, the more energy the blower consumes to maintain CFM. The LPD construction is engineered specifically to minimize that pressure drop while still delivering full MERV 10 efficiency. Across a year of continuous operation, the energy savings on a typical commercial AHU more than pay for the filter itself.
