On the 10th-generation Accord Honda put the cabin filter in the easiest possible place: a snap-in housing on the HVAC box right behind the glove box. There are no screws to remove on most cars — you unclip the glove box damper arm, squeeze the bin sides past two moulded stops, and the whole filter housing cover pops off by hand. Fifteen minutes, and the only real tools are a flashlight and a plastic pry tool so you do not gouge the dash.
It is identical across 1.5T, 2.0T and Hybrid, so ignore engine-specific guides. The two things people get wrong: forcing the glove box down before releasing the side tabs (that snaps them), and installing the filter upside down. The airflow arrow on this car points down, not toward the front of the vehicle. If you are chasing a musty smell, replacing the filter alone often will not fix it — spray an evaporator cleaner into the open slot while the filter is out.

Flashlight or headlamp LED, hands-free preferred The filter housing sits deep in the dark footwell behind the glove box.
No difference. The 1.5T, 2.0T and 2.0 Hybrid all use the same cabin filter, the same location behind the glove box and the same tool-free access; the Hybrid's high-voltage components are under the rear seat and are not involved.

AI-generated procedure overview
Park, switch the ignition fully off and make sure the climate fan is not running. Open the passenger door and put a towel over the door sill trim.
Empty the glove box completely — anything left inside will fall out when it drops.
Open the glove box fully. On the right-hand side, unclip the damper/slow-drop arm from its ball pin using a plastic trim tool, or remove the single small Phillips screw if your trim uses one.
Squeeze the sides of the glove box bin inward to clear the two side stop tabs, then let the box swing down past its normal stop. It stays hinged on the car — full removal is not needed.
Look into the opening: the rectangular filter housing cover is on the HVAC box, roughly behind the middle of the glove box opening. Squeeze the two tabs on the cover (one on each end) and pull it straight off.
Slide the old filter out horizontally, keeping it level so debris does not dump into the footwell. Note the airflow arrow — on the 10th gen it points DOWN.
Vacuum the filter tray and the housing mouth. Wipe with a microfiber towel. If you are using evaporator cleaner, spray it in now per the can directions and let it drain.
Slide the new filter in with the airflow arrow pointing down and the frame squared up in the guides. It should slip in with no force; if it binds, it is upside down or cocked.
Refit the cover until both tabs click, then lift the glove box, seat the side stop tabs back inside the dash opening and reconnect the damper arm (or refit the screw).
Start the car, set the fan to high and check for even airflow and no whistling. Reload the glove box.
Watch out
Do not force the glove box past its stops without releasing the side tabs first — the plastic stop tabs snap and the box will then flop open.
Install the filter with the arrow pointing down. Backwards, an activated-carbon filter loses most of its odour performance and can shed carbon into the blower.
Cheap oversized aftermarket filters can buckle in the housing and let unfiltered air bypass around the frame; if it needs shoving, it is the wrong part.
Never spray evaporator cleaner into the blower motor opening or onto the blower resistor — spray only into the filter slot toward the evaporator core.
Wear a mask if the old filter is black or mouldy; it also pays to check for rodent nesting material, which is common in cars parked outdoors.
Frequently asked
Which way does the cabin air filter go in a 2018-2022 Honda Accord?
The airflow arrow printed on the filter frame points down. If your filter has 'UP' or 'AIR FLOW' markings, orient it so the arrow faces the floor when the filter is seated in the housing.
Do I need tools to change the Accord cabin filter?
Practically none. A flashlight and a plastic trim tool to unclip the glove box damper arm are enough on most cars; some trims have one small #2 Phillips screw holding the damper bracket. No sockets are required.
How often should the cabin filter be replaced on a 10th-gen Accord?
Honda's guidance is roughly every 15,000-30,000 miles or once a year. If you drive dusty roads, park under trees or notice weak airflow on high fan, do it annually.
Will a carbon cabin filter reduce airflow or hurt the A/C?
A quality activated-carbon filter costs only a small amount of airflow and is fine on this car. Problems come from thick no-name filters that do not fit the housing properly — stick to the Honda 80292-TF0-405 size or a reputable equivalent.
