Two Prius Glove Boxes
Open Lower Glove Box
Side Damper Arm
This automotive "how-to" guide was specifically written to assist owners of the third generation (2010, 2011, 2012, 2013, 2014 & 2015) Toyota Prius hybrid hatchback in cleaning or replacing the A/C system's cabin air filter element.

Owners of the previous 2nd generation 2004-2009 Prius and other Toyota, Lexus or Scion vehicles such as the Yaris, Corolla, Matrix, Camry, Sienna, Avalon, Highlander, RAV4, FJ Cruiser, Venza, 4Runner, Sequoia, Tacoma, Tundra, IS250, ES350, tC, FR-S, iQ, xD, and xB may also find these DIY instructions to be helpful.

A few compatible aftermarket cabin air filters include the following with their part numbers: Fram CF10285, Wix 24483, TYC 800108C, K&N VF2000, Purolator C35667, EPAuto CP285, Pentius PHB5667, Installer Champ BE-285, Beck Arnley 042-2082 and Denso 453-1019.

No tools are needed to access the cabin air filter element.

Pop Off Damper Arm
Arm Off Mounting Peg
Push Sides Inwards
The first two steps are to sit in the front passenger seat and open the lower of the two glove boxes. Empty out the contents.

Then locate the damper arm on the right side of the glove box and pop it off the mounting peg.

If you have trouble disconnecting the damper arm with your fingers, use a screwdriver for some more leverage.

Release Side Wall Stops
Lower Glove Box
A/C Blower Motor
Firmly push inwards on the two side walls of the glove box until the side stoppers can be pulled out past the dashboard.

Gently lower the glove box down to the front passenger floor mat. The hinges of the glove box may come apart as you lower the glove box, but they can easily be re-connected later.

Behind the glove box, you'll see the white plastic blower motor housing and the rectangular cabin air filter access cover.

Press Release Tab On Right
Swing Filter Cover Open
Filter Cover Removed
Press the release tab on the right of the filter cover inwards and swing the cover open towards yourself.

Pull the tab on the left side of the filter cover out of the slot on the housing.


Slide Out Cabin Air Filter
Filter Element Housing
Clean Filter With Vacuum
Slide the old cabin filter straight out of the housing. Make a mental note of how the "Air Flow" arrow is orientated.

On this 2012 Prius, the cabin filter had the word "UP" with an arrow printed on the front edge indicating how the element should be installed.

If your old filter is relatively clean such as the one above, you can just tap out the large debris and clean it with a vacuum before re-installing it.

If your old filter is dark grey or black and clogged with dirt, dust, hair, insects, leaves and other debris, it should be replaced with a brand new element.

I recommend buying the Fram CF10285 "Fresh Breeze" cabin air filter since it has excellent reviews on Amazon. I also like how it has Arm & Hammer baking soda and carbon in the filter to help absorb odors.

Slide In New Filter
"Up" Arrow On Filter
Insert Tab Into Slot
Slide the cleaned or new cabin air filter straight into the blower motor housing.

Your new filter may either have an "Air Flow" arrow that needs to be pointed down or the word "UP" with an arrow printed on the front edge that needs to be pointed upwards.

Insert the tab on the left side of the filter cover into the slot on the blower motor housing and swing the cover closed to the right.

Gently secure the clip on the right side by pushing it until it clicks into place.

Snap Filter Cover Closed
Filter Cover Replaced
Snap Glove Box Hinges
If the glove box's hinges came apart when you lowered it, line up the two halves of the hinges and snap them together.
Push In Side Wall Stops
Push On Side Damper Arm
Close Lower Glove Box
Firmly push in the side walls of the glove box until the side stops can be re-inserted into place.

Push the hole at the bottom of the damper arm on the right side of the glove box back on to its mounting peg.

Close the lower glove box to complete the job.
