Time and Effort

Time: 5–10 min­utes

Dif­fi­cul­ty: Easy


Process

Tip: It’s best to be parked where you can com­fort­ably open your pas­sen­ger side door wide

Empty Glove Compartment

  • Take the stuff out of the glove com­part­ment

Lower the Compartment

Remove Stop Arm

  • With the glove com­part­ment open, look to the right side and locate the stop arm. Use a fin­ger to pull it until it pops off

Press the Tabs

  • Then press the tabs on either side of the glove com­part­ment to unhook the box

  • It will swing down­wards. Just leave it there. It does­n’t need to come out.

Note: If you did­n’t unload the con­tents, every­thing gets dumped on the floor…


Open the Filter Cover

  • On either side of the upper­most, sol­id plas­tic, rec­tan­gu­lar door are 2 tabs that keep it in place. Push aside (out­wards) the plas­tic tabs until both sides free from the lit­tle tab. Be care­ful not to break any­thing!!

Hint: you may need to push aside any imped­ing wiring bun­dles.

The right was easy, but the left required two hands: one to push, and one to pull the fil­ter door down

Here’s a close up of the left-side tab from my 2023 Mach‑E. The wiring bun­dle butts up against the tab, mak­ing it dif­fi­cult to remove. The 2024 was much eas­i­er with­out the wiring in the way as much

  • Push up or aside any way­ward wiring bun­dles and reach your fin­gers (or a plas­tic pry tool) up and around the two sky-fac­ing tabs. Pull care­ful­ly down to open the door

Warn­ing: Be care­ful of the met­al frame! It’s sharp!


Remove Old Filter

  • There it is! Just reach in, pull out the old air fil­ter, and note the direc­tion of the air­flow arrow
Ta Da!

Place New Filter

  • Com­pared to the Motor­craft fil­ter, the Puro­la­tor is much stiffer. Just posi­tion and slide it in


All Steps in Reverse

  • Close the fil­ter door and press until you hear/feel the click on both sides

  • Pull the glove com­part­ment back up into posi­tion until the side tabs click into place
  • Replace the stop arm on the side of the com­part­ment by just giv­ing it a nice push

  • Put your stuff back in

All done!

YOU DID IT! Super easy, AND you saved your­self some mon­ey!

How To Change Install 2022 Ford Maverick Cabin Air Filter

10/09/2022

Cost: $20.65 + tax & $9.97 ship­ping from here (end­ed up being a tiny but less expen­sive than buy­ing from Ford which is, at this writ­ing, out of stock any­ways)

Time: Under ide­al con­di­tions, about 5 min­utes.

Mate­ri­als: Motor­craft Cab­in Air Fil­ter (FP99)

Installation

The glove box

On the side of the glove box when opened, is a plas­tic stop arm. You need to pull it off…This was, by far, the most dif­fi­cult part of this instal­la­tion because the car is new, and all of the plas­tic is very stiff. The nor­mal method would be to just hook your fin­ger in there and pull. In this case, I need­ed pli­ers but also a microfiber cloth to give it more con­tact (bonus, that reduces dam­age to the piece).

So, if you’re hav­ing trou­ble, brace the glove com­part­ment with your knees, wrap the lit­tle top of the split head with the microfiber (or what­ev­er), squeeze with the pli­ers, and slide the arm off. Geez. Here’s a clos­er look at the offend­ing mech­a­nism. Now that it’s been done once, it is much eas­i­er to do for the future.

On either side of the glove com­part­ment are nice, use­ful tabs. Just depress on both sides and pull the glove com­part­ment out.

The rec­tan­gu­lar box is what we’re look­ing for. To the left and the right are 2 tabs that hold the lid in place over the hous­ing open­ing. Push them apart to free the tabs being held there. Nor­mal­ly, you would just pull the two tabs on top, and it would come out, but the plas­tic is extreme­ly stiff hav­ing nev­er been used, so be care­ful not to break the pieces (I did that in my old car D:) and pull the cov­er down.

Ta da!

Here is a side by side of the new and old. Mim­ic the direc­tion of the air­flow on the orig­i­nal fil­ter. Ford has the labeled on the plas­tic for you, also.

Mhmm. It was time.

From here on out, just go back­wards to replace every­thing: close the fil­ter lid, hook the hinges into their slots, push the glove com­part­ment up until the tabs lock in place, and then replace the stop arm.

Make sure those hinges are placed in prop­er­ly!

The one impor­tant thing to remem­ber is to make sure that the 3 hinges are prop­er­ly seat­ed. If they’re not, then the com­part­ment won’t close smooth­ly. One of mine weren’t clicked in right and clos­ing the com­part­ment was dif­fi­cult and rough.

You are DONE and breath­ing much clean­er air.
