The photos below are of some very important paper that almost all of us use on a daily basis, most don’t even realize it. As you may have guessed, it’s an Air Cleaner Filter, similar to what is used in your car (this one is from a mower). The filters job is to remove dirt and other particles that can, over time, cause your engine to wear out quicker.
It’s important to ensure your filter is clean for two primary reasons:
1. so that it isn’t letting any dirt past
2. a dirty filter restricts the air flow, reducing the fuel efficiency and power of the engine.
An easy way to tell if you need a new one, is to pull it out, and look through it at a bright light. If you can’t see the light, then it’s time to replace it! Depending on how bad it is, you may notice the difference in fuel economy (esp. if you calculate it), and maybe it’s “pep”. It’s also a good idea to ensure you have a recent tune up and that your oil is changed on schedule. All these things help the longevity and efficiency of you car’s engine.
