Owner's manual calls it the "dust and pollen filter," does not show where it is or how to replace it, and says that not all models have it! This suggests that the climate control models have one but the models with non-thermostat-controlled heat and air conditioning do not have one. Doesn't sound good. I like clean air.

 

my ex has cabin filter.
it does not have thermostat control AC / heat
it's behind the glove box.

 

Yes its behind the glove box, the cr-v has them too, we buy them at napa auto parts a lot cheaper than buying them thru Honda or paying them to do it. Can be easily done within 5 mins or so

 

I think all the US Fits have one.

It's probably the easiest maintenance item of all in the car to take care of. I think it's even easier than the windshield washer fluid, possibly depending on how much junk you've accumulated in the glove box.

 

OK I found it.
