Engineering Excellence: How WIX Oil Filters Work

Understanding the fundamental operation of an oil filter is essential to appreciating the engineering behind WIX products. At its core, an oil filter is designed to ​remove contaminants from engine oil, including dirt, metal particles, and other debris that can accumulate over time. These contaminants are byproducts of engine operation, and if left unchecked, they can cause significant damage to critical engine components through increased friction and wear. WIX Oil Filters address this challenge through a multi-faceted approach to filtration technology 11.

The filtration process begins as oil enters the filter through perforations in the base plate. The oil is then forced through the filter media, which is strategically designed to trap harmful particles while allowing clean oil to pass through. WIX utilizes ​advanced media materials​ including enhanced cellulose and synthetic fibers that create a maze-like path for oil to navigate. This path effectively captures contaminants as small as 9-21 microns (a human hair is approximately 70 microns in diameter), depending on the specific filter model. This meticulous filtration ensures that even the smallest abrasive particles are removed from the oil circulation system 4,5.

One of the key differentiators for WIX Oil Filters is the inclusion of specialized components that enhance functionality. Most WIX filters feature an ​anti-drain back valve​ made of flexible silicone that prevents oil from draining out of the filter when the engine is turned off.
