Purolator is very pleased to announce the latest improvement in self-supported pleated filters - the Key Pleat" MERV 8, standard-capacity. The new Key Pleat is the result of the on-going commitment and investment Purolator is making to improve the science of air filtration and the quality and performance of its air filter products.

Seven-strap Die Cut - A seven-strap die cut is located on the air-leaving side of the Key Pleat MERV 8 providing additional strength and durability to each filter.
100% Adhesive Application Ensures Filter Strength - The inside of the die cut frame is completely coated with adhesive to ensure a solid bond at all points of contact with the media pack.
Water Repellant Adhesive - The sealant used to bond the frame to the media pack is highly water-repellent. That means that the filters maintain structural integrity even when wet; no delaminating, excessive buckling, or collapsing.
Uniformity of Pleats - The uniformity of pleat height and spacing ensures optimal performance throughout the useful life of every Key Pleat MERV 8 filter. The combination of the self-supporting media and the innovative, automated construction also means low resistance to airflow and cost-effective, environmentally responsible use of energy resources.
