What Are The Different Types Of Oil Filters?

Your engine’s life is powered by its motor oil. It protects your car’s engine from organic and inorganic pollutants. It also improves its performance and productivity. However, automobile makers could consider fitting oil filters that clean the oil before it begins its journey to extend the life of your engine and deliver greater performance. However, they may be widely divided into two categories of oil filters: main and secondary oil filters. 

In this article, we will research about different types of oil filters.

The Different Types Of Oil Filters

Filter For Primary Oil

Most car makers employ a full flow filtration system that includes the main oil filter, also known as a full-flow filter, that can remove pollutants from all of the engine oil.

Because extreme cold may make your motor oil thick, and conventional filters restrict oil flow, making filtering harder. A full-flow filter is suitable for lower weather. The following are the most prevalent types of primary oil filters:

  • Eco oil filter: In many circumstances, it may be easily recycled. Your mechanic can usually inspect the cartridge filter without removing your engine oil if it’s positioned upright.
  • Spin-on oil filter: It is not as environmentally beneficial, unlike the cartridge oil filter.

Filter For Secondary Oil

This filter cleans less than 10% of your car engine’s motor oil and removes pollutants that your primary filter may have missed. It gives an extra layer of engine protection and might help your motor oil last longer.

A secondary oil filter is separate from the primary oil filter. These are the two sorts of secondary filters that can help your primary filter work better.

  • Spinner Oil Filter: a centrifugal oil filter is also known as a centrifugal oil filter. In most cases, a spinner filter has a filter housing chamber and a membrane (filter medium). Your mechanic will only need to change the filter media if the filtration media becomes clogged, and the filter housing chamber will remain operational.
  • Magnetic Oil Filter: It can remove metallic impurities from oil, but it doesn’t have much dust or dirt retaining ability. A magnetic oil filter does not need to be updated.

3 Frequently Asked Questions About Engine Oil Filters

What Is An Engine Oil Filter Made Of?

  • Tapping plate: The filter element via which motor oil enters and exits the oil filter.
  • Filter material: A web of synthetic fibres that collects dust and debris from polluted oil. For greater filtration, the filter material is crumpled into pleats.
  • Anti-drain-back valve: prevents engine oil from leaking into the oil filter.
  • Relief valve: discharges unfiltered oil, allowing your engine to run smoothly.
  • End discs: On either end of the automobile oil filter, two end discs prevent unfiltered oil from flowing into the engine.

What Is The Definition Of Thermal Chamber Oil Filter?

Thermal chamber oil filters protect your automobile from engine wear in two ways:

  • To eliminate pollutants from the motor oil, it is filtered.
  • The temperature is raised to purify the motor oil and remove some pollutants.

What Are The Different Filter Media Types?

  • Filter medium made of cellulose
  • Filter medium made of synthetic oil
  • Filter medium made of microglass

Filter Media Types

  • Cellulose filter media: it may keep back particles as small as 8 microns and clean up to 40% of the motor oil. 
  • Filter medium made of synthetic materials: Synthetic media is used in higher-quality oil filters. Every 5,000 to 7,000 miles, these oil filters should be checked and replaced.
  • Media for micro-glass filters: A very fine metal media or micro glass is used in most high-end oil filters. The fibres in this micro glass mesh are ten times finer than cellulose fibres. They also impose significantly less of a constraint on the user.

Filters For Oil Of Various Types

  • Primary oil filters are commonly referred to as full-flow filters, which filter all of the engine oil. These oil filters feature fewer flow limitations since they must perform efficiently to keep the engine lubricated. Motor oil thickens at cooler temperatures, and an oil filter that is too tight might cause engine harm. 
  • Secondary oil filters: Some manufacturers install secondary oil filters and primary oil filters. These oil filters remove a little percentage of the motor oil, usually 1% to 10%, before returning it to the engine. Consequently, you’ll have to change the motor oil less often. You can opt to add a secondary oil filter after purchase, even if your car does not have one. However, it’s vital to realize that they’re not the same as the bypass valve.
  • Conventional oil filters: These oil filters employ simple cellulose membranes and are a type of secondary filter. They need to be replaced more regularly since they filter out tiny pollutants.
  • Thermal chamber oil filters have two modes of operation. They filter the motor oil to eliminate impurities and boost the temperature to ensure that some pollutants in the motor oil are burned off or destroyed. In a sense, these oil filters purify the oil, but they do it by using power. This is why they might impair your car’s fuel economy.
  • Spinner filters, also known as centrifugal oil filters, employ a spinning action to collect and retain impurities in motor oil. These oil filters usually have two parts: a housing chamber and a membrane. When the media becomes clogged, all you have to do is change it while the housing chamber is still functional. 
  • Magnetic oil filters remove metallic particles from engine oil; however, they are useless against dust. 


Oil filters are critical components of your vehicle that must be maintained. It cleans motor oil by eliminating harmful impurities and contaminants that might reduce the vehicle’s efficiency. As a result, oil filters help your engine run more efficiently and for longer periods. Replace them as directed to keep your engine safe from tainted oil. Also, pay close attention to the oil filter maintenance or replacement directions. These guidelines are usually based on the circumstances you travel in daily and your mileage.
