What is an Air Filter?
Air ain’t all sunshine and rainbows. There is dirt and dust in the air we breathe, and guess what? Your vehicle breathes that same air. And that’s where your air filter comes in.
Think of your vehicle's air filter as a bouncer at the club. The air filter keeps those airborne contaminants from entering the engine, which is good for the engine’s health. In the process, it allows your motor to breathe properly without all the dirt and dust. Long story short, the air filter receives air, kicks out the contaminants that are bad for the engine, and lets the motor move along smoothly. It’s easy peasy.
And that’s kind of it. Not much for you to have to learn here. But let’s dig a little deeper, in case you still have questions. Why does your car need clean air, you might ask? Well, the engine pulls air in and uses it for combustion. The air mixes with the fuel in a combustion chamber, where, after it’s ignited, it explodes. And that’s how your car gets its power.
So, you can probably see why it’s important to have a clean filter. The filter reduces how much nastiness enters your engine at this critical time and place
Air filters get a lot of use because your vehicle uses a lot of air. So, the filter wears out, and they’ll need to a replacement with some regularity.
And before you ask, no: Don’t even think about cleaning your air filter and putting it back in. Just replace the damn filter. It’s quick, simple, and affordable.
Symptoms of a failing Air Filter
Lack of power
Come on, car! When you notice that your vehicle isn't as powerful as it used to be, it may be time to check and replace that air filter. When the filter gets severely clogged and dirty, they restrict air flow to the engine, stopping it from taking full, deep breaths. Why does that matter? Well, you try going for a run without taking any full, deep breaths. Not so fast anymore, are you?
Poor fuel economy
Time to fill up…again? Yup, that may be a bad air filter. When your engine is starved of air, it doesn’t work as efficiently. Again, think of taking a run without any full, deep breaths. Are you going to be able to run as far? No, you’re not. And your car isn’t, either. Being unable to operate efficiently means you need to expend more energy to do less. In the case of your car, that means using more fuel. Which means getting worse mileage. Which means spending more money at the gas tank. With that in mind, it might save you a lot of money to replace your filter. It’s worth noting that a car’s computer can compensate for a lot when it comes to engine performance and fuel efficiency, so modern engines aren’t as susceptible to this filter problem as older engines are. But you’ll definitely notice a dip in fuel efficiency if you have an older car.
Visibly clogged filter
If your filter is looking filthy, it’s time to get a replacement. That seems simple enough, right? Now look: I know you’re probably not checking in on your filter every day, so no judgement here if you haven’t noticed it. But a technician sure will, so if you’re having your car serviced or your oil changed, a professional will easily spot a filter that you need to replace.
Scheduled filter maintenance
Ahh, so close. You thought you could get through this whole article without the dreaded “scheduled maintenance” tip, and you almost did. But here we are. After certain intervals of distance and/or time, your manufacturer recommends investing in an air filter replacement. So, when you reach those milestones, replace that filter. Seriously.
How urgent is an Air Filter replacement?
To keep your engine healthy and running its best, the air filter should be replaced in accordance with the manufacturer’s maintenance schedule, or as soon as it’s apparent that it’s clogged up and not functioning properly.
