Review on Enhance Cabin Air Quality with K&N Premium Cabin Air Filter for Toyota/Subaru/Land Rover/Jaguar/Lexus/Scion: High Performance, Washable, Clean Airflow (VF2000) by Doug Layman

I like the ability to clean and not throw away every time. I noticed a "different" smell in the air after installing and using it for the first time. It was naturally very mild and didn't oversaturate at all. I didn't feel anything else for several kilometers. Maybe it's one of those things where it has an odor to begin with and then you either get used to it and don't smell at all anymore, or the outgassing from the rubber seal or chemical in the area becomes less noticeable over time. Update: I couldn't get used to the smell. The smell hasn't faded over time. I had to take it out of the car and put the paper back in. I have cleaned it and will let it air out a bit and then try again. Downgrading to 3 stars due to smell.
