Purolator is pursuing a clearly defined goal—to maintain and extend their position as a market leader in filtration technology. To achieve this, they are focused on producing top-quality products, offering first-class service, and engineering with innovation to keep pace with ever evolving engines and oils.

Back in 1923, Ernest Sweetland and George H. Greenhalgh patented the first automotive oil filtration system. They called their invention Purolator, short for the words pure oil later. Since then, Purolator has been manufacturing, marketing, and distributing filters for the automotive industry. In April 2012, the global filtration company, MANN+HUMMEL, acquired Purolator Filters and strengthened its position as a leading company in the automotive filtration industry. Today, Purolator has more than 2,000 filtration part numbers for automotive, light truck, and heavy-duty applications, and continues to work on product innovation and design.

In order to stay ahead of the competition for so many decades, Purolator makes sure that each and every filter leaving the production floor has been manufactured according to their high-quality standards. Purolator also has a dedicated Advanced Technology team that focuses on creating cutting-edge filtration solutions designed to fit the complex systems of today and tomorrow. And as a key division of MANN+HUMMEL Filters, Purolator exemplifies the strengths of both original-equipment quality-control processes and global manufacturing best practices.

The original Purolator was an upright series of seven twill-weave, cloth-covered, perforated plates encased in a heavy-duty cast container. The product featured glass on one side so that the oil flow could be viewed and the filter changed when the flow diminished to a trickle.
