By the way, the filter the EX500 uses is identical to what almost all Honda passenger vehicles have been using for the last 20 years, including the brand new models. Punching in a 2010 Accord, for example, will give you quite the list of usable filters in any online filter cross-reference chart. My personal preference is the Purolator PL14610. Having access to automotive filters makes them easier to get and cheaper.
