    Purolator Replacement Filter
    Purolator’s innovative Key Pleat® standard and high capacity filters are the best-performing self-supported pleat (SSP) on the market. Using breakthrough technology and processes by Purolator’s R&D team, the Key Pleat achieves a mechanical MERV 8 efficiency, extremely low pressure drop, and industry-leading dust holding capacity. The Key Pleat possesses the most consistent pleat spacing on the market, achieved with innovative media and a fully automated manufacturing process. The direct adhesion between the media and frame resists movement, bunching, and collapsing during use, supporting a consistent low pressure drop, balanced dust loading, and longer service life. The robust durability of the Key Pleat filters will save time and money previously wasted on replacing damaged wire-backed filters. With no metal that can warp or deform, moisture-resistant beverage board frame, and rugged synthetic media, the Key Pleat packs a punch and maintains its structural integrity even in wet or humid conditions.


    • Self-supported media – no metal wire backing!
    • 100% synthetic media resists moisture, mold, and damage
    • High strength and rigidity, resulting in full depth loading and enhanced dust holding capacity
    • Mechanical efficiency produces increased efficiency as media loads


    • Die cut, single-piece beverage board frame
    • Three pleat stabilizer straps on upstream side
    • Seven strap die cut on air leaving side of the filter
    • Integral media pack support grid on downstream side
    • 100% water repellent, high-strength adhesive coats entire interior of frame
    • Over 140 (SC) and 250 (HC) adhesion points between media and frame
    • Boxed pleat tips provide surface area for adhesion
