Purolator began manufacturing automotive filters in 1923 and continues to sell its products through automotive retail stores nationwide. Two of its filter styles include the Purolator Classic and PureOne. Purolator oil and air filters come in both styles, each offering different features and application recommendations.
The Purolator Classic oil filter traps contaminants in its high-density, fiber-filled unit. The lubricated Nitrile gasket allows for easy removal of the oil filter. The anti-drainback valve prevents the oil from flowing when the engine is off. PureOne oil filters also feature an anti-drainback valve made of silicone. In addition, PureOne filters have a grip control feature not found on the classic model. The difference between the oil filter gaskets includes the use of Polytetrafluoroethylene, or PTFE, on the PureOne style. The PTFE is a type of resin that can endure high heat and friction.
The type of Purolator oil filter that offers the best protection for a vehicle is based on the mileage and driving conditions. Purolator recommends the use of Purolator Classic oil filters on vehicles primarily used for highway driving and vehicles with low-mileage. PureOne oil filters perform better in high mileage vehicles and handle the stop-and-go driving conditions of the city better than the classic style.
The basic components of the Purolator Classic air filter include the fibers that trap the contaminants and the gasket that pushes the air through the filter. The PureOne air filter has the same components but offers oil-wet fiber traps and a gasket made of polyurethane binding to protect the engine.
PureOne products offer a slightly higher efficiency rating over the Purolator Classic styles. The PureOne oil filters offer a 99.9 percent efficiency rating while the classic style has a 97.5 percent rating. The PureOne air filter traps 99.5 percent of the contaminants, while the classic style holds 96.5 percent of the pollutants.
Purolator recommends replacing the oil filters every three months or 3,000 miles. The air filters require changing every 12 months or 12,000 miles to provide optimal performance.
