Which one do you run?
87139-07010
87139-YZZ20
87139-50100 (deodorant style)
Promise not to laugh at me?
In search of a better filter than stock, I tried the 87139-50100:
It was OK, some fumes were less compared to stock, but it was a real stretch to notice a difference. However, my biggest gripe with ALL the Toyota filters is how they fit in the filter holder - there are air gaps all around the edges which allow a lot of air to completely by-pass the filter.
After trying a few - all of which had the same loose fit in the filter holder:
I settled on the K&N Cabin Air Filter:
It is NOT an oiled filter. If airflow is rfeduced due to dirt, simply wash with dish soap (Dawn), air dry and re-use. Optionally, some air freshener can be sprayed on the filter after cleaning, but I have never been a fan of a car that has a foofy smell. I did try some Febreze spray on the filter and it did seem to work very well, but only for a couple of weeks.
It fits very well in the filter holder with a good seal all the way around:
I also like the warning sticker which migh help prevent ham-handed techs from reaching in and breaking the recirc cover:
Overall air volume is slightly less with the K&N, but I have never found it to be too little.
YMMV
