when you notice that the force of the air coming out of the front vents are not as strong as it used to be, then the microfilter needs to be checked. you can opt to just vacuum it. but from my experience, the filter progressively gets clogged up faster after every cleaning. six months ago, i replaced the filter. the a/c worked fine since then.Originally Posted by altec
btw: there is a note embossed on the side of the microfilter that says it has to be replaced every 12,000km. my mileage has gone past that figure since i had the new one installed, ok pa rin up to now.
