The location of a car's air filter element varies depending on the intake form and engine structure. It is generally situated in the air cleaner on the engine intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The air filter should be replaced every 10,000-20,000 kilometers or during every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of throttle sludge. Function of the air filter: To filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders and preventing airborne dust from being sucked into the engine, which accelerates wear on the piston group and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filtration device. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be drawn into the cylinders, accelerating wear on the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly problematic in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand from the air, ensuring that sufficient, clean air enters the cylinders. Dirty air cleaner: Using an excessively dirty air cleaner while driving can lead to insufficient engine intake, incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air cleaner clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its primary function is to filter out harmful impurities from the air before it enters the cylinders, thereby reducing early wear on the cylinders, pistons, piston rings, valves, and valve seats. Thus, air must pass through the fine filtration of the air cleaner before entering the cylinders. A dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if minimal dust and light clogging are found, it can be cleaned using high-pressure air blown from the inside out and reused. Excessively dirty air cleaners should be replaced promptly.

I've been driving for many years, and the air filter is usually located in the engine compartment. After you pop the hood, just take a quick glance and you'll spot a black or gray box, typically near or in front of the engine. In some cars, it's close to the battery—like in my Honda Accord, it's in a small black box at the front right. The box cover is secured with clips or screws, and once opened, you'll see the filter snugly fitted inside. Don’t mistake its location, as it filters the air entering the engine to prevent dust from damaging it. I replace mine every 20,000 kilometers—it’s super easy to DIY: turn off the engine and let it cool, unclip the cover, pull out the old filter, and slot in the new one. Last time I forgot to replace it, my fuel consumption spiked before I realized the filter was clogged with dust. Now I’ve learned my lesson—regular maintenance saves fuel and protects the car.

As a car enthusiast, the location of the air filter is super cool. I often tinker with cars in the garage, and it's usually fixed inside the engine compartment—just pop the hood to see it. In most cars, it's inside a plastic box with tubes at the front of the engine. For example, my old Ford had it on the left side of the engine, and the cover just snaps open. The placement is cleverly designed to ensure air is filtered before entering the engine, preventing dirt and sand from getting in. If you frequently drive on dusty roads, you should replace the filter more often, or the engine may accumulate carbon deposits. I recommend checking it every spring and autumn—consult your owner's manual to confirm the exact location, so you don’t accidentally open the cabin air filter box. Replacing it yourself saves time; just buy the right filter for your car model and install it. Learning some mechanical know-how is great—I find it both cost-effective and rewarding to do it myself.

I usually commute in a small car, and the air filter is located in the engine compartment. After opening the hood, look for a square box near the engine, typically positioned on the upper right or left side, easily recognizable by its plastic material. The cover is usually secured with clips; open it to find and replace the filter. Make sure to remember its exact location, or it might be difficult to install a new one. The air filter plays a crucial role in blocking dirty air to protect the engine. Neglecting to replace it can lead to engine inefficiency and increased fuel consumption. My husband taught me that the manual recommends checking its position and replacing it every 15,000 kilometers. A simple method: operate after parking and letting the engine cool down—safety first. Learning to do it yourself ensures peace of mind and smooth driving. Don’t delay too long to avoid major issues.
