  • MERV 11-15 performance rating
  • High efficiency synthetic media
  • Low pressure drop
  • Reduced energy cost
  • 194 square feet of media ( 24x24x12)
  • Incinerable
  • Light-weight plastic, extremely rigid frame
  • Superior dust holding and prolonged filter life


    • The DuraMAX 4vS is a rigid, extended surface air filter, engineered to provide maximum performance and prolonged filter lifecycles, even in the most difficult environments.

    The durable, rugged construction of the DuraMAX 4vS make it the filter of choice in filtration systems with high velocities or variable air volumes. DuraMAX 4vS is constructed with an all plastic frame so it is easily incinerated after use.

    Low Pressure Drop Reduces Energy Costs
    DuraMAX 4vS provides an unequaled combination of low pressure drop and high efficiency through the use of our unique minipleat design.
    This high capacity minipleat design allows a nominal 24 x 24 x 12 filter to incorporate 194 square feet of filter media.
    This increased extension of the media surface area insures low pressure drop, which results in lower energy costs to the user.

    Extended Filter Life
    Another benefit of the increased media area is extremely high Dust Holding Capacity, which significantly prolongs the service life of the filter.
    Fewer filter changes translate into substantially reduced maintenance and disposal costs.

    Engineered Versatility
    In order to meet the wide range of requirements found in today’s complex air filtration systems, DuraMAX filters are available in five ASHRAE efficiencies (65, 75, 85, 95, and 98%).
    The filter is offered in three standard sizes (24 x 24 x 12, 20 x 24 x 12, and 12 x 24 x 12).
    Single or double header configurations are available.
