If you don't change your cabin air filter regularly, you may be putting yourself and your passengers at risk. The filter will become clogged with dirt and debris, reducing the efficiency of your car's filter and HVAC system. This can lead to bad odors in the passenger compartment, as well as the growth of mold, which can cause serious health issues if inhaled. By replacing your cabin air filter on a regular basis, you can avoid breathing in unhealthy mold and keep your cabin smelling fresh.
It will also prevent pollen from entering the vehicle, which can cause sneezing and other uncomfortable effects. Unfortunately, many people neglect this important part of regular vehicle maintenance. The engine air filter removes toxic pollutants from the air that the engine absorbs for combustion. The car cabin air filter helps remove harmful contaminants, such as pollen and dust, from the air you breathe in the car.
Changing the cabin air filter isn't just about air quality, it's also a safety issue and a maintenance requirement for the climate control system. When the cabin air filter is dirty and clogged, the engine has to work harder to power the heating or air conditioning. Replacing 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. It will also help keep your car's air conditioning components in good condition, such as the AC fan motor.
If your air conditioning system sounds like it's blowing louder than usual, it could be a sign that your cabin air filter needs replacement. Mileage maintenance suggestions may vary depending on the year, make and model of a vehicle, but generally it should be changed or at least checked every 15,000 to 30,000 miles. Ignoring this recommendation can have serious consequences for your health and safety.
