What does an air filter, cabin air filter or fuel filter do?

All auto filters are designed to prevent harmful debris from entering vehicle parts where air and fluid flows. This includes your engine, A/C, radiator, fuel lines and more. Once a filter is no longer performing its intended function, decreased performance – or, in severe cases, even engine damage can result.

Just like in your home, filters for your vehicle are just as important. Here’s what each automotive filter does:
Engine air filter: Prevents harmful debris, dirt and contaminants from entering your engine.
Cabin filter: Prevents dust, pollen, dirt and other pollutants from entering your car through your A/C and heat vents.
Fuel Filter: Keeps dirt, debris and contaminants from clogging your fuel lines and causing erratic, unstable fuel performance and reduced fuel economy.

How often should an air, cabin air or fuel filter be replaced?

Generally, it’s recommended that you get your filters replaced every 12 months or 12,000 miles, but check your owner’s manual for specifics about your vehicle’s filter replacement schedules. Here at Hobson’s Auto, we check these filters at every oil change!

What happens to air, cabin air or fuel filters as they get older?

Any filter – home, auto or otherwise – will eventually age and become contaminated with pollutants and debris. When that happens, the filter loses its effectiveness and hinders the performance of the parts it is supposed to protect.

What can happen when filters are clogged or dirty? A dirty air filter can cause your engine to work harder, resulting in poor fuel economy, higher emissions and, possibly, a loss of engine power. In turn, as a worst-case scenario, a clogged cabin air filter can lead to under-performance of the A/C system, causing weak air flow from the cabin vents. It can also lead to unwanted, unfiltered air in the cabin. As for a mucked-up fuel filter, that’ll land you with a weakened fuel supply to injectors, a reduction in engine power, poor acceleration and lousy fuel economy – not to mention a potential breakdown.

Replace old filters regularly to avoid placing stress on other vital car parts.

What is the benefit of replacing an air, cabin air or fuel filter?

The benefits are car-saving and performance-enhancing. They protect vital car parts by keeping harmful debris at bay so your car runs right. Filters also ensure your car runs more efficiently. The cleaner your filter, the more it allows for the maximum flow of air or fluid through the system. Like a clogged drain, a dirty filter starves the system of the vital air or fluid and makes each system it protects work harder to do its job. Once filters are dirtied, they really should be replaced.

The purpose of each filter is clear: to trap and protect.
