Introduction
To improve the environment inside the car, a clean air filter is fitted to the heater intake. This is intended to remove dust and particles that would otherwise enter the car. The filter fitted to the RAV is a particulate filter which has been electrostatically charged to capture the finest particles that are also positive or negatively charged and attracted to the filter. New filters are snow white but soon become blackened by the volume of tiny particles trapped within them. The result as well as a fresher interior is cleaner interior and air vents etc. A filter that is becoming clogged will also starve the interior of fresh air and windows will quickly steam up so it is very important to replace the filter as at the correct interval or more frequently under dusty conditions. Replacement filters with an activated carbon core may become available which also remove odours that may occur for instance in heavy traffic.
The filter will soon become clogged with flies and leaves etc. The blackening is due to dust and pollen (even smaller than the pores in the filter) that have been attracted to the filter fibres. It is very easy to access this filter so I recommend that you remove and clean the filter at least every 12 months and if it looks clogged, replace it.
