Why You Should Change your Car Air Filter

Posted on

Did you ever wonder what your air filter does?

Not many people know the importance of a car air filter and why you should change it frequently, but we are here to help explain why.

The filter cleans the air that comes into the car interior through the heating, ventilation and air-conditioning system. It does this by catching dust, pollen and other airborne material that can make travelling in a car unpleasant. It’s a real bonus for those suffering from allergies or other respiratory problems such as asthma.  (Read our blog on making driving more bearable when the pollen count is high.)

The filter is usually made from multi-fibre paper cotton, which allows it to ‘breathe’ and it works similarly to the air filters that you use for your vacuum cleaner.

Drivers often overlook replacing the air filter, as it doesn’t stand out as an important part of the vehicle, like the lights, indicators and tyres. Ignoring it can lead to an unpleasant experience sitting in the car as well as possible damage to the air con system.

When to change it?

It is important to regularly service your car air filter to keep the system working effectively.

Driving your car frequently can have a bigger impact on your air filter as it is likely to become clogged quicker.  On average it’s recommended to change it every year or every 12,000 to 15,000 miles.

Common signs that an air filter needs changing

• A reduction in air flow to the HVAC (heating, ventilation and air conditioning) system.
• Increased noise from the fan as it works harder to deliver fresh air.
• A bad odour when you turn on the air in your vehicle.

Always check your car manual for more details as the manufacturer’s recommendations vary.
