Air Filter Replacement in Greenford
Your engine air filter keeps dust and debris out of the engine, while a separate cabin (pollen) filter keeps the air inside your car clean. Both need replacing periodically, and a dirty filter can affect performance, fuel economy or air quality inside the cabin. MH Auto Repair Centre replaces engine and cabin air filters at our Perivale/Greenford workshop. If your car feels sluggish, uses more fuel than usual, or the air conditioning smells musty, message us on WhatsApp and we’ll help you get it checked.
What Is Air Filter Replacement?
Most vehicles have two separate air filters. The engine air filter cleans the air drawn into the engine before it mixes with fuel, preventing dust, dirt and debris from causing wear inside the engine. The cabin filter, also known as a pollen filter, sits in the ventilation system and filters the air that comes through the vents into the car, catching dust, pollen and other particles. Both filters gradually become clogged with use and need replacing so they can keep doing their job properly.
Signs You May Need an Air Filter Replacement
A few signs can indicate one of your air filters needs attention:
- Reduced engine performance or acceleration that feels less responsive
- Engine using more fuel than usual
- Unusual engine noises or rough idling
- A musty or stale smell from the air vents
- Weaker airflow from the heating or air conditioning system
- Visible dust or debris around the air filter housing when checked
- Your vehicle is due an air filter change under the manufacturer’s schedule
You don’t need to wait for an obvious problem before having your filters checked. Because both filters gradually clog over time, manufacturers usually recommend replacing them at set intervals. If you’re not sure whether your filters need attention, our team can check them as part of a free vehicle inspection.
Engine Air Filter or Cabin (Pollen) Filter?
These are two different parts doing two different jobs, and it’s common for customers to only need one replaced rather than both. The engine air filter protects the engine itself and mainly affects performance and fuel economy when it’s dirty. The cabin (pollen) filter affects the air quality and airflow inside the car, and a clogged cabin filter is often behind a musty smell or weaker airflow from the vents. Tell us which symptoms you’re noticing on WhatsApp and we’ll check the right filter, or both, during your visit.

How We Carry Out an Air Filter Replacement
The exact process depends on where the filter housing sits on your vehicle, but replacing an air filter generally follows a similar sequence:
- Locate and open the relevant filter housing (engine bay for the engine filter, usually behind the glovebox for the cabin filter)
- Remove the old filter and check its condition
- Clean any dust or debris from the housing
- Fit a new filter suited to your vehicle
- Secure the housing and confirm everything is seated correctly
- Carry out a free vehicle inspection before handing your car back
What Affects Air Filter Replacement Cost
We don’t publish a fixed price for air filter replacement, because the cost depends on a few factors specific to your vehicle:
- Vehicle make and model
- Whether the engine filter, cabin filter, or both need replacing
- The filter type required for your vehicle
- Any additional work identified during inspection
Message us on WhatsApp with your vehicle details and we’ll talk you through the likely cost before any work begins.
How Often Should Air Filters Be Replaced?
How often each filter needs replacing depends on your vehicle, driving conditions and the manufacturer’s schedule, so we don’t quote a single interval that applies to every car. Vehicles driven in dustier conditions or on higher mileage may need filters changed more often. Send us your vehicle details and last service date on WhatsApp and we can advise.
Air Filter Replacement vs Full or Interim Service
Air filter replacement is often included as part of a wider full car service, and your filters are also checked as part of our interim service. It can also be carried out as a standalone job if a filter needs attention sooner than your next service is due. If you’re due a wider service as well, our team can advise on the best approach for your vehicle — see our full range of car servicing options.

FAQs
How do I know if my air filter needs replacing?
Reduced engine performance, higher fuel use, a musty smell from the vents or weaker airflow from the heating and air conditioning can all indicate one of your air filters needs attention. If you notice any of these signs, message us on WhatsApp and we’ll take a look as part of a free inspection.
What’s the difference between an engine air filter and a cabin (pollen) filter?
The engine air filter cleans air going into the engine and mainly affects performance and fuel economy when dirty. The cabin, or pollen, filter cleans the air coming through your vents and affects air quality and airflow inside the car. Many vehicles need each replaced at different times, so we check both during a free inspection.
How much does air filter replacement cost?
Air filter replacement cost depends on your vehicle and whether the engine filter, cabin filter, or both need replacing, so we don’t publish a fixed price. Message us on WhatsApp with your vehicle details and we’ll talk you through the likely cost before any work begins.
How often should air filters be replaced?
This depends on your vehicle, driving conditions and the manufacturer’s schedule. Send us your vehicle details and last service date on WhatsApp and we can advise on the right timing for your car.
Is air filter replacement included in a service?
Air filter replacement is often included within a full service, and your filters are checked as part of our interim service too. It can also be carried out as a standalone job if needed sooner. We can advise on the best option for your vehicle.
What happens if I don’t replace a dirty air filter?
A dirty engine air filter can reduce performance and increase fuel use, while a clogged cabin filter can leave the cabin air feeling stale and reduce airflow from the heating and air conditioning. Message us on WhatsApp if you’d like either filter checked.
