How often to change cabin air filter?
I replaced my cabin air filter 12 months ago. I drove approximately 5,000 miles. It now has that moldy smell common with the a/c filter when it gets dirty. I haven't checked the filter, but wouldn't it be really soon to change a cabin filter after only 5,000 miles? Here in Florida the a/c never shuts off. Could it be an inner component that needs to be sprayed or cleaned as well? Thanks all.

Here is a link to another earlier thread. It seems to be somewhat common is the South where it is very humid and if you keep your AC on recirculate all the time.

2-3 times a year I check and vacuum out the cabin air filter. About every other year I might replace the filter depending on how it looks.

Certainly no harm in doing this occasionally but a little caution may be warranted. High concentration isopropanol (rubbing alcohol) can damage rubber with long term exposure. I would not use anything higher than 70%.

The bottle reads 70%. I sprayed a little less than half the bottle. Hopefully I should be good and am not planning on doing this on a regular basis.

I do mine every 3-6 months or so. The first time when the smell was particularly bad the color of aftermath coming out of the drain tubes was green... If you leave your AC on recirculate all the time it seems to promote the issue. Since then I just clean my smog sensor regularly, set it to max sensitivity, and leave it on auto switching. That is another easy and great diy. Cleaning the smog sensor.
