How to change the cabin filter on 2006 Honda Odyssey?

It's located under and behind the dashboard glove box.

A 1996 Honda Odyssey is not equipped with a cabin air filter. If I was looking for a restriction in the cabin air, the first place I would look is on the inlet side of the A/C condensor. ALL cabin air travels through the A/C condensor ALL of the time. (The heater core only sees air when the temp door is not directing the air around it and always after it has been through the condensor first.) I have seen gunk as hard as concrete clogging the condensor just from layers of dirt that collects on the wet coils then dries.

The Cabin air filter is located behind the glove box, There is a plastic cover that must be removed to change the filter, if the filter has never been changed a plastic bracket may have to be removed also.

Open the glove compartment and release the stops on either side to allow it to drop all the way down. Behind it there should be a plastic cover about 4-6" long and 1" tall with tabs on one or both sides. Remove the cover and pull the filter tray out. Replace filter (or filters) and reassemble.

I have a factory manual for 1999-2004 but I believe the filter is in the same location on a 2005. First, you have to remove the glove box. It's a straight forward process with a phillips head screwdriver and a 10mm socket. The filter is in the middle of the black plastic air handler behind the glove box. It is in a vertical slot covered by a narrow "door" with clips on top and bottom. If it has never been changed before, you will have to cut out the horizontal plastic cross brace that kept the dash assembly from warping during manufacture. Cut with a hack saw at each end of the plastic brace and remove it. You'll notice a metal cross brace that can be removed with screws at each end. Once the braces are removed, it is easy to unclip the filter door and replace the filter. Then just put everything back except the plastic cross brace you removed; it can be thrown out.

Remove the glove box housing. Remove the dust and pollen filter assembly from the evaporator. Remove the filter from the housing, and replace the filter. Install in reverse order.

While holding the lower glove box, release the damper and remove the glove box stop on each side.
Remove the bolts, then remove teh lower glove box. Install the lower glove box in the reverse order of removal.

Your Honda Odyssey comes with only 2 filters: an engine intake air filter and a cabin filter.
