Owners of other Toyota and Lexus vehicles such as the Camry, C-HR, Venza, Avalon, 86, Sienna, Tacoma, RAV4, Highlander, 4Runner, Sequoia, IS 350, RX 350, UX 200, GS 350, IS 300 and ES 350 may also find these DIY instructions to be helpful.

A few compatible replacement cabin air filters with their part number are as follows: EPAuto CP157, Spearhead BE-157, Purolator C31434, TYC 800217P and Beck/Arnley 042-2229.

No tools are required to access and replace the cabin air filter.

The first few steps are to sit in the front passenger seat, open the glove box and empty out the contents.

Move to the outer right side of the glove box (close to the passenger door) and locate the black plastic damper arm.

Note - On this 2020 Corolla, the glove box damper arm was missing. So just imagine that it is there in my pictures.

Firmly push in the two side walls of the glove box until the plastic side stops can be released from behind the dashboard.

Don't worry if the plastic hinges come apart. They can easily be re-assembled later on.

Once the glove box out of the way, you'll be able to see the HVAC blower motor housing and the rectangular shaped filter access cover.

Pinch or squeeze together the two tabs on the right side of the filter cover.

Swing open the right side of the filter cover.

Set the filter access panel aside in a safe place.

Slide the black plastic filter tray straight out of the slot in the HVAC blower motor housing.

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

I recommend buying the EPAuto CP157 cabin air filter since it has excellent reviews on Amazon from other Toyota owners.

If the old filter is relatively clean, pull it out of the tray and remove any fine dust with a vacuum cleaner.

Note - Most aftermarket brand cabin air filters will have an "AIR FLOW" arrow that should be pointing down into the blower motor and towards the floor mat of the vehicle.

Make sure the new filter is fully seated in the tray and in the correct orientation.

If your vacuum cleaner has a crevice attachment, clean out any large debris in the slot.

Orientate the filter tray with the plastic grates facing down, the "UP" arrow pointing up and the white filter pleasts facing up.

Slide the filter tray straight into the slot.

First, re-insert the two tabs on the left side of the filter cover into their corresponding slots.

Swing the filter cover closed towards the right side of the filter slot.

Push on the filter cover to secure the retaining clip.

You should hear or feel the retaining clip "click" securely into place.

Raise the bottom edge of the glove box towards the dashboard.

Line up the plastic hinges with their mounting bars.

Push the hinges over the bars to re-assemble the hinges.

Push the bottom of the damper arm on to the mounting peg attached to the outer right side wall of the glove box.

Replace the contents of the glove box and close it to complete the job.

Be sure to write down the filter change in your car's service records.

Enjoy the fresh clean air from your A/C system!
