I removed the filter and inspected. It comes in black color - so difficult to view dirt - but I can see the light through it well. Advice? Also how often do u guys change it? Mine is 39k and 8yrs old.
If you can see light through it, it should be ok. You can blow it out gently with an air compressor or can of compressed air too. If still concerned, buy a new one and compare light through it vs. the existing one.
If the interior of your car is kept clean they should be okay. If you have pets, maybe not. Buy new ones if you’re not sure. Only a few bucks.
Yep just blow it out and you're fine. I, also, shine a light in there and inspect the blower fan vents...don't want lint or hair to be built up in there. (We have dogs so I check them often but have been clean, so far.)
These filters are so cheap just buy new ones. Don't use a blower or vacume. Dealership where I am in canada is sells them for $5 each side. Probably best to change them every 2-3 years. If you live in the city Probably even longer.
