Having a cabin air filter in your car is essential for ensuring the air quality inside your vehicle. Without a cabin air filter, pollutants such as diesel fumes, burnt oil, and allergens can enter the car and cause health risks. Additionally, small leaves and garbage can get stuck in the system, depending on the size of the inlet. The cabin air filter is a small pleated filter made of multi-fiber paper cotton or other engineering material.
It prevents dust, dirt, pollen, bacteria, and exhaust fumes from entering your car's HVAC system. When air passes over the cabin air filter, debris is trapped by the filter and stops instead of being pumped into the car. Changing the cabin air filter at regular intervals will ensure that passengers don't have to roll down windows in the middle of winter to get fresh air. With a clogged cabin air filter, lack of air flow can be felt in the dashboard grilles and will result in lackluster defrost and defrost performance, as well as reduced air conditioning and heating functionality.
Simply changing the cabin air filter will dramatically improve your vehicle's air quality. But what about hazards that can't be seen and effects that are only noticed gradually or during certain modes of operation? The reality is that a foul-smelling cab isn't the most pressing problem drivers will face if they never change the cabin air filter or don't change it often enough. If you find yourself driving in heavily polluted areas or traveling on dirt roads, you should change your cabin air filter every 5,000 miles. If you smell an unpleasant scent coming from the air conditioner, there is a high chance that your air filters will not work properly.
Clean air is essential for your vehicle to function properly; your car's engine air filter ensures that clean air reaches the engine.
