If you want to know the signs that your filter needs to be changed, pay attention

If you don't have your user manual or you want to know the signs that your filters need to be changed, pay attention:

Reduce or weaken the airflow, even if the heating or air conditioning is set to high

The air intake of the cabin emits a whistling sound

A musty, unpleasant smell enters your car through the air

The noise during the operation of the heating or cooling system is too loud

If you encounter any of these signs in your car, please consider replacing the filter to see if the problem can be solved.

Other steps to protect your vehicle

You can take additional measures to maintain air quality and prevent other allergens from settling in your car:

· Regularly vacuum decorate and carpet floors and MATS.

Wipe the surfaces, including the door panels, steering wheel, console and dashboard.

Check whether the sealing of the weatherproof strips on the doors and Windows is correct.

Clean up spills immediately to prevent mold growth.

Problems related to dirty filters

Clogged and dirty air filters may cause other problems for you and your car. One possibility is that your health condition is deteriorating, as pollutants can move in the air and cause allergic reactions or breathing problems. Dirty filters cannot work properly and filter out contaminants, so it is very important to replace the filters in the car frequently. Consider replacing it every February before the start of the spring allergy season.

Another problem caused by filter clogging is the poor efficiency of HVAC. As a result, your car's heating and cooling systems will have to work harder, which may cause the blower motor to burn out. Low efficiency can also lead to air flow loss, which makes your car feel less comfortable as the seasons change.

Weakened airflow can also affect the system's ability to clear fog or condensate from car Windows. Dirty air can cause condensation to accumulate on the windshield, making it difficult for you to see the road ahead. By replacing the filter, you should notice that the Windows are clearer and the visibility is better.
