This automotive maintenance tutorial was specifically written to assist owners of the sixth generation "B16" (2007, 2008, 2009, 2010, 2011 & 2012) Nissan Sentra sedan in cleaning or changing the A/C system's cabin air filter element.

Owners of other Nissan vehicles with similar HVAC blower motor housings such as the Versa, Cube, Altima, Maxima, Leaf, Pathfinder, 370Z, Juke, Rogue, Xterra, Murano and Quest may also find these DIY instructions to be helpful.

A few compatible replacement filters with their part numbers include the following: Purolator C25864, TYC 800126P, Fram CF10550, Wix 49352, Premium Guard PC5864, Hastings AFC1251, Mann MC 1069, Bosch C3907WS, Pentius PHB5864, Beck Arnley 042-2157 and Mahle LA 396.

No tools are needed to replace the filter. A wet/dry shop vacuum can be useful for cleaning and reusing the existing element.

Plastic Friction Fasteners

Plastic Filter Access Cover
To access the cabin air filter, you'll first need to remove the plastic kick panel on the driver's side next to the gas pedal.

Gently pull the kick panel straight off to disengage the plastic friction fasteners.

Set the panel aside in a safe place.

Just to the right of the accelerator or "gas" pedal, you'll see the rectangular black plastic filter access cover.

Pull Off Retaining Clip
Plastic Clip At Bottom
Remove Filter Access Panel
Pull the retaining clip at the bottom of the filter cover down and to the left to release it.

Swing open the filter cover and then lift the top off the blower motor housing.

Empty Filter Slot
You will need to compress the filter and bend it a bit forward in order to slide it out past the metal bar and the gas pedal.


Inspect Both Sides
Clean With Vacuum
Compress & Re-Insert
Inspect both sides of the filter.

If the old filter is relatively clean, just tap out any large debris and remove any fine dust with a vacuum.

If the old filter is dark grey or black and clogged with pollen, dirt, twigs, leaves, insect and hair, it should be replaced with a new element.

I'd recommend using the TYC 800126P cabin air filter since it has the best reviews on Amazon.

Slide In Cabin Filter
New Filter Installed In Slot
Line Up Filter Cover
If the new filter has an "Air Flow" arrow, it should be pointed towards the rear of the vehicle.

Compress the pleats of the new cabin filter and slide it in to the slot.

Continue sliding in the new filter until it is flush with the opening in the blower motor housing.

Attach Hook Tab On Top
Snap On Clip At Bottom
Filter Cover Replaced
Line up the filter cover and lower the small hook and tab on the top of the slot.

Swing the filter cover closed and snap the retaining clip on the bottom in place.

Make sure that the filter cover is securely in place.

Line Up Friction Fasteners
Push On Kick Panel
Plastic Kick Panel Replaced
Line up the friction fasteners on the rear of the kick panel and gently push it back in to place.

Be sure to record the filter change in your vehicle's service records.
