I like to get Honda OEM ... but you can also get a good aftermarket brand with activated carbon to get rid of musty smells, like this one..Buy Honda filters or a good aftermarket?
New and old pictures:Just replaced my cabin filter on my 1 year old Crosstour with a Fram "FreshBreeze" Carbon and Baking Soda filter. Cost was about $15, took less than a minute to replace. When inserting the new filter into the carrier be sure the filter folds seals into the ends of the carrier to assure an airtight installation.
Filter was a little dirty after a trip to West Texas and driving through some sever Dust Storms. I have about 8,000 miles on the car so far.
Turns out my 2003 Accord uses the same filter, replaced it also!
