What are the three types of oil filters?

December 08, 2025

Oil filters come in several designs, but they generally fall into three main types. Each type works differently to clean the engine oil and protect the engine from harmful contaminants. Understanding these filter types helps you choose the right one for your vehicle or machinery.

Mechanical (Primary) Oil Filters

Mechanical oil filters are the most common type. They use pleated filter paper or synthetic media to trap contaminants as oil passes through.
Key features:

  • Captures dirt, metal particles, and sludge

  • Simple, reliable, and widely used

  • Requires regular replacement
    Mechanical filters are used in most cars, trucks, and equipment due to their strong balance of cost and performance.


Magnetic Oil Filters

Magnetic oil filters use strong magnets to attract and hold metal particles suspended in the oil.
Key features:

  • Excellent at capturing ferrous (iron-based) contaminants

  • Can be cleaned and reused

  • Often used as a supplemental filtration system
    While magnetic filters don’t remove dirt or non-metal particles, they help protect engines from metal wear debris.


Sedimentation (Gravity-Based) Oil Filters

Sedimentation filters rely on gravity to separate heavier contaminants from the oil.
Key features:

  • Allows heavy particles to settle at the bottom of a reservoir

  • Used mostly in older machinery or specialized industrial engines

  • Slower filtration but requires less frequent replacement
    This type is less common today due to advancements in modern filtration systems.


Summary

The three main types of oil filters are:

  • Mechanical filters — standard filters using physical media

  • Magnetic filters — capture metal particles using magnets

  • Sedimentation filters — separate contaminants by gravity

Most modern engines use mechanical oil filters, while magnetic and sedimentation systems are used in specific applications or for additional protection.
