About Purolator®



Purolator invented the oil filter in 1923 – and we have spent the last century relentlessly perfecting oil, air, cabin air and fuel filters. You’ll find Purolator filters on every back road, main street, and highway in communities just like yours around the country. Debris and dirt aren’t going anywhere, and we’ll remain a step ahead of the contaminants that threaten today’s high-tech engines.

We Invented The Oil Filter

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”, and they began a story of quality and innovation that continues to this day. 

While the original Purolator filtered oil through twill-weave cloth, in 1946, Purolator introduced a pleated paper oil filter - a technology still being used today.

Over the years, Purolator developed filtration products for transmission fluids, power steering fluids, hydraulics, coolants, crankcase emissions, and other liquids and gasses. As the holder of thousands patents, Purolator has consistently innovated and led the very industry we invented.

Work. Ethics.

Purolator’s hardworking people are thorough, diligent and in constant pursuit of new learning. And rest assured, nothing gets by us. Nearly a century after inventing the oil filter, Purolator continues manufacturing to the high standard maintained by American workers in Fayetteville, North Carolina. You’ll find those filters protecting engines on every back road, main street and highway in communities like yours around the country.

We Saw that Coming

Engines and oils have evolved dramatically in the past decade. Keeping pace with this technology requires a daily battle against the destructive contaminants that attack vehicles from the inside.

At Purolator, we study these particles obsessively -- down to the molecular level. Because they must not get through to the engine, or to the passengers. Not on our watch. This forward thinking mentality has led to continuous innovation in automotive filtration.

Reshaping the Industry

We’re bringing a renewed quest for innovation to the automotive filtration industry. Along with the promise of true choice for filter buyers. While holding strong to the ideals we’ve always stood for: Protection. Craftsmanship. Experience. And trust.
