How To Tell If Your Lexus Cabin Air Filter Is Malf

Air pollution is unfortunately prevalent in many cities today. Breathing in these exhausts and fumes daily can be detrimental to your long-term health. That is why your vehicle contains a cabin air filter to capture airborne contaminants, ensuring that the air you are breathing in when you are on the road is clean and safe. Over time, however, the filter’s pores can become clogged with dirt and the filter starts malfunctioning. This can affect the quality of air in the cabin, result in inadequate air and cause the AC to use more power. Since cabin air filters are usually hidden from view, many drivers do not think about servicing their cabin air filters. However, if your Lexus cabin air filter is malfunctioning and in need of changing, it will exhibit some of the signs below:

Increase in Fan Noises

You should only be able to hear the soft noise of air escaping the vent when you turn on the air conditioning system of your car. This is an indicator that your air cabin filter and air conditioning system are healthy. However, if you begin to hear louder noises from the fan, it might be a sign that your cabin air filter is malfunctioning. When large particles pass through the air cabin filter, the filter will have difficulties properly filtering the air, creating loud noises when the air flows through.

Poor Airflow from Vents

One of the most obvious signs that your cabin air filter is malfunctioning would be the poor airflow coming from the vents in your car. Since a contaminated air filter filters air less efficiently than a clean one does, this results in restricted airflow for the air conditioning system leading to poor airflow in your car. This creates additional stress on your car’s air conditioning system which could escalate to be a costly problem as your air conditioning is forced to work harder when the filter is malfunctioning, using up more fuel in the car.

Unusual Odor coming from Vents

It is unsurprising that if you experience some unusual odor from the vents in your car, it might be a sign to get your car to a service shop as soon as possible A filter that is extremely dirty will lead to a musty or dusty smell pumping through your car’s vents which will further intensify if you try to increase the airflow of the air conditioning system.

Icy or Foggy Windows

A large function of the cabin air filter is to maintain the airflow within the vehicle to clear out any fog that forms on the windows. Having a malfunctioning cabin air filter makes it difficult for any condensation to be removed from the window due to the weakened airflow, resulting in icy or foggy car windows especially if you live in a cold climate. This poses a huge safety risk for you and others on the road which could potentially be fatal and so should be avoided at all costs.
