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
POP!
Press the Tabs
Then press the tabs on either side of the glove compartment to unhook the box
Tabs on either sideClose-up
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
PositionPUSH!Boom!
Put your stuff back in
All done!

Owned Supplies
Hair Cutting Cape
Comb (clippers come with one)
Water Spray Bottle
Broom and/or Vacuum Cleaner
Process
What follows is the original, very first haircut I did myself December 2025 where I was really nervous. Skip to the bottom for Notes and my subsequent cuts
Prepping
Gather supplies and clear any rugs or anything else in the cutting area. Little hairs will fly! Keep everything within easy reach
Secure the cape
Follow manufacturer’s instructions on oiling the clipper. The thing I read beforehand said to put one drop on either side of the blades and then back
Grab the spray bottle and comb, then mist the hair so that it’s mildly damp but not sopping wet
I couldn’t find a spray bottle, so I used a wet comb and that does not work very well
Then comb straight so that all the hair lays flat
My hair is at least 2 inches too long
Know the gameplan. Apparently, the rule of thumb for close cuts is to do the sides then the back first. Because I wanted to keep the top a bit longer, I needed to alligator clip the hair there out of the way so I could deal with it later
The problem with such large clips is that they get in the way of the clipper
Cutting!!
Starting time!! The recommendation is to use the clipper guards and to go more conservative first. You can take away hair but not put it back.
To start, I used a #4 guard to address the sides. The technique is cut straight into the air and to NOT follow the curve of the head just yet.
Deep Breath! LET’S DO THIS!
Right Side
Before
After
Hmm… Didn’t wet the hair enough, so it was really difficult to cut the strands
Left Side
Before
After
Wet it more this time and it was easier. The only hard part was using my left hand instead of my right
Now for the trimmer! Using the trimmer and/or the corner edge of the clipper (no guard), fold the ear and trim around the contour
This trimmer was TERRIBLE. The on/off switch was literally impossible to flip and for the number of times you need to do that, it was super obnoxious and hurt my fingers. That’s what happens when I decide to go cheap
left
right
Interestingly, my hair is different on both sides. In the end, I knew I’d need the help of scissors to polish it off
Now for the back. I stuck with the #4 guard to take the bulk off. Utilizing the side mirrors by turning either left or right to see more (you have to use the mirror in the mirror effect), I was able to take off the bulk of the length. The straight back, I used a two-handed motion similar to that dumbbell exercise
Before
After
Now there are those little strands in the back. I decided to use the trimmer again. This part was super hard because I couldn’t see anything and no amount of phone or mirror could help me. In the end, I just used the comb as a straight edge. I knew I’d want another person to help me out later.
They sell these back of head guides that you can secure around your forehead
And for the riskiest part: Fine tuning. With the bulk gone, it was time to do detail work. If the length was good for a trim, I would’ve been fine, but I didn’t want that. I want shorter!
Stupidly, I went straight from the #4 to a #1 for whatever dumb reason. If I was seasoned, it’d be fine, but I was brand new to this!! So, of course, I made a mistake.
Whoops. Too much, too fast
After laughing nervously, I decided to fix it. Slowly this time. I went from a #3, to a #2, then a #1. Each guard number I went all over with until I got used to wielding the clipper.
I actually wasn’t intending to ever go back to the #1, but I did in the end because it was the only way to get the bottom of the back to hug the skin and look more natural.
Helpful: Just because you use a guard doesn’t mean you’re limited to it. On the side of the clipper is a lever that further controls the length. So, using a #3 plus the lever effectively gives you #3.1 – 3.9. This allows more control to fine tune and is how I ended up fixing the hair and feeling comfortable with the rest of the fine-tuning process. It ends up being a trial-and-error/practice thing.
After fixing everything, I felt much better and things were looking good as a whole. Now for the mid-tier! I swapped to the #6 to do the curve of my head, then the #4, and eventually #3 (only a little)
For the other side of my head, I removed the clips, combed, then added the clips the other way this time. Time to cut!
Before
After
More fine tuning all the way around. This is where I finally figured out how to properly use the tri-fold mirror.
The female head has a much more pronounced dip/roundness in the back than a typical male head, so I had to take that into account
Hmm. I missed some on the right side
Happy with the sides and back, normally, this is where Hair Scissors come into play. Alas, I did NOT have any. I also knew better than to use regular scissors or the clippers. I would have thinned and layered the top using a 2-finger hold and cut method, then fine-tuned the contours of the ears.
And DONE!
Go clean up and take a shower!
Before and After Pictures
Notes:
1st Cut 12/27/25
Very freeing and so much easier than I thought it would be! A few hiccups in the learning process, but overall, I can see myself doing this for years to come. The tri-fold mirror was instrumental in all of this! I would highly recommend it! I’m already imagining other styles I can try in the future! It’s nice to not only save money, but do this at my own leisure, in my own house!
I needed someone else’s help for the scissor-work and contouring of the back and ears, so I have yet to try that myself. Shouldn’t be too hard. I’ll update whenever I do that in the future.
While the longer top style-wise wasn’t too bad looking, I can’t staaaaand hair in my face, so it just got annoying
If using the large hair clips, make sure to push them way up high or they’ll get in the way of the clipper
Definitely use a spray bottle
I didn’t realize the back of my head is so bumpy. If the pictures look like I chopped to much in some places, it’s actually because of my head structure
2nd Cut 2/21/2026
Cut in the kitchen this time which was much better and brighter than the bathroom. Mess up AGAIN in the same spot because I forgot to return the clipper lever to the lowest level which means that, yet again, I needed to use the #1 guard to smooth it out. It went much faster than the first time because I not only felt more comfortable as a whole, but I properly utilized the 360 Mirror. Vacuum cleaner is much easier than broom and dustpan. Shorter to start this time around and shorter to end with. Also did not have scissors and had help for the final touches yet again.
LEFT: Pre-cut; CENTER: Messed up in the lower corner, so had to cut on guard #1 to smooth it out; RIGHT: Post-cut
3rd Cut 4/12/2026
Hair was shorter to start with, but longer to end with than previous iterations (mostly because I didn’t mess up as badly). This time employed scissors to help, so it took a bit longer to complete. Still messed up when trying to use the comb + clipper method to detail towards the top. Looks bad, but not as bad as the bottom of the hairline. It’s really nice to be able to cut whenever I feel like on my own. This time, I’m going to add some more notes to the process now that it’s more streamlined.
Wet and comb throughout the process
Pin hair as desired
Choose a Guard – Used #3 with the clipper level on the shortest setting
Clip the sides and the back using the 360 mirror – Use the middle to start, then the mirror-in-the-mirror images (i.e. When cutting the right side, look to the left; When cutting the left side, look to the right). Use an underhand hold and cut upwards.
Underhand hold for the back
Mirror-in-mirror image with scissors
Ear and Back Detail – Wet, comb, then use scissors and/or mini clippers. BE CAREFUL!! This is the easiest place to mess up!
Shorten and Fade as desired. Used #2 guard ON THE LONGEST CLIPPER LENGTH first, then at half lever for the middle, and then the shortest on the lowest portion of the head. Use a scooping motion with the clipper to prevent sharp edges
Detail Time – I removed 2 hair clips and then went in small increments with the clipper level. Be careful if you’re trying to use the comb as a guard to help. That’s where I messed up this time… heh… heh… Sigh.
Scissor Work – First time using scissors. I read somewhere that the best way to cut bangs is to use the comb as a guide and do vertical snips to make it look more natural. I’m not going for bangs here, but I figured it worked similarly?
Final Touches – Look all around for evenness. I ran the guarded clipper around again to make sure all the areas were cut and found that I’d missed the upper back corners near the top of my head
