Defiant Mark 80-D - The industry standard for performance and value for over 30 years.

Gain 1 Point toward LEED Certification - During the process of new construction, install MERV 8 filters at each return air grille for air handlers used during construction. Conduct a two-week building flushout with new air filters and 100-percent outdoor air prior to occupancy.

Proprietary MERV 8 Media - Developed to deliver consistent performance. - The heart of the product. Purolator medias are manufactured to exclusive specifications produced only for Purolator. Nobody pays more attention to media specifications than Purolator. Rigid requirements for resistance, efficiency, MERV values and dust holding capacity are verified by QC checks on incoming raw materials, production line sampling and field audits of finished goods.

Mechanical Media - Defiant Mark 80-D filters are made with 100% synthetic fibers providing mechanical efficiency to achieve a MERV 8 performance. Defiant Mark 80-D filters maintain a MERV 8 performance before and after a conditioning step. The MERV 8 media has a PVA (Ployvinyl Acetate) adhesive that is not affected by mold or microbial growth.

Heavy Duty Deverage Board Frame - Moisture resistant, sturdy frame material stands up to rough handling, difficult service conditions, long service life. The new 7-strap die cut pattern increases contact points between the beverage board and die cut by 50%.
