Bought a couple of geniune honda jazz carbon cabin filters from ebay.
made in guangzhou, sadly both filters did not fit USDM fit, they were close, but off by 5mm in length. (to long)

 

dremmel.. would fix that man

 

or snip one of the pleats.

 

What about a trying a HEPA filter? There was a thread a while back about using them (just search on the word "HEPA")

That is, if we are talking about the same thing.

 

if it's like this one http://cgi.ebay.com/GENUINE-HONDA-PA...QQcmdZViewItem
then i could possibly understand why, the part number on the bag for it is for a 98-02 usdm accord, though the usdm accord use's 2 filters instead of 1, but the part number is the exact same 80291-S84-A01, however that's not the same part number for the usdm FIT a/c filter.

 

thats the one I tried.
