Who Makes Purolator Oil Filters?

Purolator invented the first replaceable automotive oil filter in 1923 and established its name worldwide as a leading manufacturer of automotive filters.

After changing hands several times, Purolator is currently owned by the German company Mann+Hummel. 

Mann+Hummel is based in Ludwigsburg near Stuttgart in Germany. Mann+Hummel is a multinational company employing 21,000 employees in over 80 locations worldwide. The company claims to be the global leader in filtration systems with over eight decades of experience.

The Canadian subsidiary Purolator Inc is not part of the Mann Hummel owns Purolator, and the Canada Post Corporation owns 91% of the Purolator Inc.

Mann and Hummel also place importance on manufacturing regions in Asia and Europe.

Are Purolator Oil Filters Filters Proudly American Made?

Although Purolator is not American-owned, several manufacturing sites are currently manufacturing oil filters in the US for domestic and international sales.

Mann +Hummel stress their strong regional focus, yet they also have a vested interest in lower-cost production facilities in China, Mexico, and India.

Sources point out that Mann+Hummel recently stated that their HVAC systems are now manufactured in China under the Dupont label, which may be a trend the US oil filters may follow in the future.

It is a known fact that Mann+Hummel entered the Chinese market in 1996 and now owns four manufacturing sites in Changchun, Jinan, and shanghai. The fourth company based in Jiading is an oil and fuel filter manufacturer. 

Although the Purolator brand filters aren’t listed on the American-made listings, there is local manufacture in North Carolina, and some of their products are locally made.
