MANN+HUMMEL Purolator Filters LLC, more commonly known asPurolator, is an American manufacturer of oil and air filters, based inFayetteville, North Carolina. Since 2013, it has been a subsidiary of German filter manufacturerMann+Hummel. Purolator manufactured and sold the first commercially available automotive oil filters starting in the 1920s. For several decades in the late 20th Century, Purolator operated a large North American courier business known as Purolator Couriers. Canadian courierPurolator Inc. and its subsidiaryPurolator International are the successors of that business but have had no direct relationship with their former parent since 1987.
The company was founded in 1923 asMotor Improvements, Incorporated inNew York City.[1] The company's Purolator (initially stylizedPurOlator and sometimesPur-O-Lator) oil filtration device,[2] invented in 1922 byErnest John Sweetland[3] and George H. Greenhalgh,[1] was standard equipment on early 1920sChrysler automobiles after being launched on theChrysler Six.[2] The namePurolator was a portmanteau ofpure oil later.[1][4] The Purolator was the first modern automotiveoil filter[3] and reduced the need to flush a car'scrankcase to clean out oil contaminants, at the time a regular and costly maintenance item.[5]
In 1924, Purolator filters were made available for retail sale for both passenger cars and trucks[6] and Motor Improvements president James A. Abeles announced it had established a network of 2,600 sales, installation, and service stations across the US and Canada[6] and had engaged ad firmMacManus, Inc. for a nationwide advertising campaign.[7]
The company later changed its name to the name of its most well-known brand,Purolator Products, Inc..[1]
In the 1950s and 1960s, Purolator, headquartered in Rahway, New Jersey, diversified their operations by acquiring a variety of hardware and automotive parts manufacturers. These included Bridgeport Manufacturing Co. in 1959[8] and in 1961, Hadbar, Inc. and On Mark Couplings, Inc. both of Los Angeles, California.[9][10] Among its acquisitions in 1965 was Stant Inc., a Pine Bluff, Arkansas manufacturer of radiator and fuel caps which continued as an independent subsidiary of Purolator.[11]
In 1967, Purolator expanded into the courier business by acquiringAmerican Courier Corp. (ACC) of Bayside, New York for overUS$5 million. ACC operated as an independent subsidiary of Purolator.[12][13] ACC had been founded asArmored Car Service in 1948[14] and its primary business was transporting checks between banks.[15] Following the acquisition by Purolator, ACC made a number of acquisitions aimed at consolidating its business nationwide including the 1969 acquisitions of both Fort Worth, Texas-based Armored Motor Services, Inc.[16] and Tampa, Florida-based Security Transport Corp.[17] By 1971, ACC said it had 1,272 vehicles and had started aSky Courier division with 17 planes and 30 pilots.[18] ACC was renamedPurolator Courier Corp. in 1973.[19]

Purolator Courier boughtTrans Canadian Couriers in 1972 to expand its Canadian reach.[20][21] In 1973, Trans Canadian was renamedPurolator Courier, Ltd.[22]
In 1982, William Waltrip resigned as president and CEO ofPan Am after less than a year to become president and CEO of Purolator.[23] Waltrip's major initiative was to refocus the company on its courier business.[24] To that end, in 1983 Purolator soldPurolator Armored, its armored car division formerlyPurolator Security, to Australian armored car service provider and owner ofLoomis Armored Car Service,Mayne Nickless forUS$33 million.[25] By the end of 1983, Purolator operated 270 terminals, 111 aircraft, and 5,328 ground vehicles and reported it had handled 76,841 packages in the year.[24]
In April 1984, parent company Purolator Inc. was merged with subsidiary Purolator Services and US courier subsidiary Purolator Courier Corp. to form a new company,Purolator Courier, Inc. It also consolidated the parent company headquarters, previously in Piscataway, New Jersey, and the Courier's headquarters, previously in Long Island, New York, to a single facility in Basking Ridge, New Jersey.[26] At the same time, Purolator began to move to compete with package delivery companiesUnited Parcel Service andFederal Express by announcing it would introduce a two-day service it calledStandard Service in 1985. While revenue rose in the third quarter of 1984, earnings declined due to the company's heavy investment in new equipment as it continued expansion of its courier business. At the time, Purolator's air and ground courier businesses accounted for 75% of the company'sUS$800 million revenue, far eclipsing the original automotive manufacturing business.[24]
By 1987, Purolator was experiencing significant financial challenges having reported losses ofUS$57.6 million onUS$841.4 million in revenue for the previous year. The company had spent significant capital building an air fleet in previous years, an endeavor that analysts partially blamed for its financial decline.[27]
Following the 1983 sale of Purolator Armored and Purolator's 1984 restructuring, the parent company was the US courier business, Purolator Courier, Inc. Its major subsidiaries were Purolator Products, the original auto filter business, Purolator Courier Ltd., the Canadian courier business, and radiator and fuel cap manufacturer Stant. Unable to maintain its operations, the company was broken up in a series of transactions all occurring in 1987.[27]
Purolator Products was sold to filter manufacturer Facet Enterprises for aboutUS$167 million.[28]
Purolator Courier Ltd. was sold toOnex Capital Corp. forUS$170 million.[20] In 1993, Onex sold 75% of Purolator Courier toCanada Post forCA$24 million,[29] a holding later increased to over 90% in 1998.[30] In 2011 Purolator Courier Ltd. changed its name toPurolator Inc..[31][21]
Purolator Courier Inc., the parent company, was acquired by Emery Air Freight. For Emery, the acquisition of Purolator was financially troublesome and led in part to Emery's 1989 acquisition byConsolidated Freightways forUS$230 million. Within 30 days of the acquisition, Emery and Purolator Courier had been merged with Consolidate's CF AirFreight to become a single entity,Emery Worldwide, with all former brands including Purolator retired.[32]
Stant was sold with the parent company to Emery. However, Stant was bought out by a management-led group in a leveraged buyout later in 1987. It was independent until 1997 after which it has been owned first byTomkins plc then, since 2008,H.I.G. Capital.[33]
Following its acquisition by Facet, Purolator Products's headquarters were moved from Edison, New Jersey to Tulsa, Oklahoma where Facet's existing filter subsidiary, Facet Automotive Filter Co., was based. Purolator's manufacturing facilities in Fayetteville, North Carolina and Mississauga, Ontario were not moved.[34]
In 1988, Facet and its subsidiaries including Purolator were acquired byPennzoil forUS$254 million[35] after having been the target of hostile bidder, Prospect Group.[36] The next year, Facet merged Purolator with Facet Automotive Filter under the namePurolator Products Inc. The resulting subsidiary was expected to be the world's largest automotive filter company and hold a 30% share of the US market.[28]
In February 1990, Pennzoil put Facet up for sale having been unable to realize expected synergies from the filter manufacturer.[37] However, by April, Purolator had been merged with Facet which was renamedPurolator Products Company and Pennzoil reported it was no longer looking for a buyer.[38] Two years later, Pennzoil spun Purolator off as an independent, publicly traded company via anIPO.[35]
In 1994, Purolator was acquired by engineering companyMark IV Industries of Amherst, New York for a reportedUS$273 million.[39]
In 1999, Mark IV sold the automotive filter business, Purolator Products, to Columbus, Indiana-based automotive component manufacturerArvin Industries forUS$276 million. At the time, Purolator reportedUS$345 million in annual sales.[40] Later in the year, Mark IV sold its remaining Purolator and Facet units, industrial filter businesses Purolator Products Air Filtration Company, Facet International, and Purolator-Facet Filter Products, to industrial filter manufacturerClarcor forUS$144.8 million.[41]
In 2006, Arvin, then known as ArvinMeritor, sold Purolator Filters to a joint venture of European filter manufacturersMann+Hummel andBosch. Mann+Hummel bought out Bosch's 50% share of their joint venture in Purolator Filters in 2013 taking full ownership of Purolator and renaming itMANN+HUMMEL Purolator Filters.[42][43]
Purolator's involvement withNASCAR dates to 1955 when it offered aUS$7,000 prize forNASCAR Grand National race circuit winners who raced using Purolator oil filters.[45] By 1970, it was sponsoringNASCAR Cup Series teamHolman-Moody with driverDavid Pearson, winner of multiple Grand National Championships.[46] In 1972, Pearson joined Purolator-sponsoredWood Brothers Racing with driversNeil Bonnett andA. J. Foyt.[47] In 1974, Purolator sponsored the inaugural 500-mile NASCAR Grand National race atPocono International Raceway, thePurolator 500.[48] The company continued the sponsorship in 1975[49] and 1976.[50] Purolator Products sponsored and won the 1990 Daytona 500 with Derrike Cope as the driver.
