Keep your cabin free from contamination
The heating and cooling system in your Toyota is great for environmental control to ensure that you, your family or other passengers are comfortable on any trip. They also ensure that there is a steady flow of fresh air running through your vehicle, which is especially important for occupants who have conditions like asthma.
Cabin filters are the barrier between your cabin and the many contaminants outside that can cause harm if breathed in, like dirt and dust, pollution particles and even bugs and insects.
Over time, these contaminants can also cause build-ups in your HVAC system that can result in blockages and damage. So it is vital to ensure that you keep getting these replaced to keep that barrier up and prevent these pollutants from getting in.
How often should I change my filters?
There is no exact science to this, as it depends on the environment you are driving in and the number of pollutants in the air. Generally speaking, though, the cabin filter should be replaced between every 5000km and 10,000km, which means roughly every service or every second service. They should be inspected at every service to see if they need to be replaced.
How do I know if it needs changing?
In between services, there are some signs to look out for before your next scheduled booking with the mechanic that indicate your filter may need changing or unclogging.
If you are noticing poor airflow from the air vents, it could be a sign of a blockage. Any strange smells coming through your vehicle, like dust or musty smells, are another sign. If you suffer from asthma or other respiratory issues, you are likely to have reactions if contaminants are making it through.
Nunawading Toyota stocks official cabin filters to suit all models, which will last longer and perform better than aftermarket alternatives. You can prepare for your next service by stocking up on these, as well as fuel filters and oil filters.
