The Flanders Pre-Pleat 40 Air Filter is a 20x20x2-inch pleated filter engineered to balance effective dust removal with low pressure drop. This MERV 8 filter combines high dust holding capacity with low initial resistance, delivering an extended filter life cycle and energy-efficient operation in heating and cooling systems.
The Pre-Pleat 40 is designed for dust holding, pressure drop, and MERV rating performance. Its construction delivers the lowest initial resistance among standard capacity MERV 8 pleated filters, making it an efficient choice for furnace and air handler applications.
Features and Benefits
- 100% Synthetic Media: High dust holding capacity combined with low initial pressure drop delivers extended filter life of up to 90 days between replacements.
