  • What is a Cabin Filter?

    Also known as an air filter or pollen filter, a cabin filter is a component installed in the heating, ventilation, and air conditioning (HVAC) system of a vehicle. It plays a crucial role in creating a more comfortable and healthy environment for cab operators.

  • What Does a Cabin Filter Do?

    The primary purpose of a cabin filter is to screen the air that enters the cabin, removing dust, pollen, pollutants, and other contaminants. By doing so, it can help improve the air quality and reduce the risk of respiratory issues, allergies, and odours.

  • How Often Should I Change My Cabin Filter?

    The replacement interval depends on various factors, including your vehicle's make and model and driving conditions. But as a general rule, it is advisable to replace your cabin filter every 12,000 to 15,000 miles (or every 12 months). You can also follow the manufacturer's specifications mentioned in the vehicle's manual.

  • Can I Clean and Reuse My Filter?

    Most cabin filters are NOT designed to be cleaned and reused. To ensure proper filtration and avoid damage, it's best to replace your filter with a new one.

  • How Do I Know if My Cabin Filter Needs Replacement?

    If you notice any of the following signs, it may be time to replace your filter:


    • reduced airflow from the vents
    • foul odours
    • increased allergy symptoms
    • visible dirt and debris on the filter
  • Can I Replace the Filter Myself?

    Absolutely. Replacing a cabin filter is generally a straightforward process but if you’re unsure, it's best to seek help from a qualified mechanic or refer to your vehicle's manual for guidance.

  • Are There Different Types of Chemical Filters for Tractors?

    Yes. cabin filters come in different types, including:


    • Standard particulate filters
    • Activated carbon filters
    • High-efficiency filters

    The type of filter you need depends on your air quality needs and budget.

  • How Do I Find the Right Cabin Filter for My Vehicle?

    You can refer to your vehicle's owner's manual or use online filter compatibility tools provided by reputable automotive manufacturers or parts suppliers. If you prefer to buy from a physical store, visit your vehicle's authorised dealership. They can provide you with the correct Original Equipment Manufacturer (OEM) cabin filter that matches your vehicle's specifications.

  • Are Cabin Filters the Same as Engine Air Filters?

    No, cabin filters and engine air filters serve different purposes and are located in different parts of the vehicle. While cabin filters are designed to purify the air that enters the interior of the vehicle, engine air filters are responsible for filtering the air that enters the vehicle’s combustion chamber.


    Cab filters are usually located in the HVAC, between the outside air intake and the passenger compartment. Air engine filters, on the other hand, are installed in the air intake system of the engine.
