Most modern cars are fitted with a ventilation system that controls their car’s heating and air conditioning throughout the changes in the year. Every system has a car air filter as part of their kit and its purpose is to release clean air into the car’s cabin. The filter removes pollen, dust and debris from the air that moves through it, which is particularly helpful for anyone who suffers from allergies like hay fever or asthma. It’s something that is often neglected and taken for granted but air filters need to be changed from time to time to ensure that they continue to work properly. We’ve put together our best tips and tricks to help you change your car’s air filter at home.
Did you know that before 2000 most cars didn’t have air filters in their air systems? The only cars that did were higher end ones and you had to pay a lot more for it.
