Thanks for reminding me about the filters. I've had my Clarity for about a year and a half, so far, with about 11k miles on it, and the cabin filter should be ready for replacement. I watched a couple of you tube clips showing the cabin and the engine air filter replacements, and was quite surprised how much debris and dirt the cabin filters had collected.
I've been pretty happy with our local Honda dealer so far, but the thought of paying the high dealer prices for the filters, and the really really high labor costs for the trivial filter replacement tasks is pretty hard to swallow. Replacing air filters is something I can still manage, even at age 80.
I just ordered a set of filters from HondaPartsNow. I haven't used them before, but their website part search UI is good, and the prices were low. The ResellerRatings on them is very high, so I'm hoping for a good result.
