Your Complete Guide to the 2017 F-150 Cabin Air Filter: Location, Replacement, and Maintenance​

The cabin air filter in your 2017 Ford F-150 is a critical yet often overlooked component that directly impacts your driving comfort, health, and your truck's HVAC system performance. Located behind the glove box, it should be inspected every 15,000 to 20,000 miles and replaced at least once a year, or more frequently if you drive in dusty or high-pollution areas. Replacing it yourself is a straightforward, 15-minute task requiring no special tools, saving you time and money while ensuring you and your passengers breathe clean air. This comprehensive guide provides all the facts, steps, and details you need to understand, locate, change, and choose the right filter for your 2017 F-150.

​Understanding the Cabin Air Filter's Role and Importance​

The cabin air filter, sometimes called a passenger compartment air filter, is your vehicle's first line of defense for the air inside the cabin. It is a pleated filter made of multi-fiber paper cotton or other engineered material. Its job is to clean the outside air coming through your truck's heating, ventilation, and air conditioning (HVAC) system before it enters the interior. It traps a wide array of particulate matter. This includes dust, pollen, mold spores, soot, and other airborne allergens. In many modern filters, an added layer of activated charcoal is included. This charcoal layer absorbs unwanted odors and gases, such as exhaust fumes from other vehicles, and reduces ozone levels from the outside air.

Neglecting this filter leads to several tangible problems. A clogged filter restricts airflow. This forces the HVAC blower motor to work harder, potentially shortening its lifespan. More noticeably, you will experience a significant reduction in airflow from the vents. The air may not get as cold or as hot as it should because the restricted airflow makes it harder for the system to exchange temperature efficiently. For you and your passengers, a dirty filter means recirculating pollutants inside the cabin. This can cause unpleasant smells, increase allergy symptoms, and contribute to foggy windows because the filter cannot manage moisture and contaminants effectively. Maintaining a clean filter is a simple, cost-effective part of regular vehicle care.

​Signs Your 2017 F-150 Needs a New Cabin Air Filter​

Recognizing the symptoms of a dirty or failing cabin air filter will help you address the problem before it affects your comfort or the HVAC system. The most common sign is noticeably reduced airflow from the dashboard vents. Even with the blower fan set to its highest speed, the amount of air coming out feels weak. You may also detect persistent musty, moldy, or generally unpleasant odors when you first turn on the fan or air conditioning. These odors are often caused by mold and mildew growing on the damp, debris-laden filter material.

Increased dust on the interior surfaces, especially the dashboard, shortly after cleaning is another clear indicator. If dust seems to accumulate inside the cabin quickly, the filter is no longer capturing it. Allergy sufferers in the vehicle may notice an increase in sneezing, itchy eyes, or other reactions while driving. Unusual noises, such as whistling from the dash, can sometimes occur as air is forced through a blocked filter. Finally, if your windows fog up easily and are difficult to clear, a saturated filter may be contributing excess moisture to the cabin air. If you experience one or more of these issues, it is time to inspect the filter.

​Preparing for the Replacement: Tools and Parts You Will Need​

The replacement process for the 2017 F-150 is designed for owner maintenance. You do not need mechanical experience. The only tool you absolutely require is a standard Phillips screwdriver. A small flashlight or the light on your phone is very helpful for illuminating the filter housing, which is in a dimly lit area. You may also want a small vacuum cleaner to clean out any leaves or debris from the filter chamber before installing the new filter. Wear gloves if you prefer to keep your hands clean, as the area around the housing can accumulate dust.

Selecting the correct replacement filter is crucial. The 2017 Ford F-150 uses a cabin air filter for all cab styles: Regular Cab, SuperCab, and SuperCrew. The part number is typically ​FP-67​ for the standard particulate filter. The enhanced version with an activated charcoal layer for odor reduction is usually part number ​FP-67A. It is vital to confirm that any aftermarket filter you purchase is listed as compatible with the 2017 Ford F-150. Reputable brands include Motorcraft (Ford's own parts brand), FRAM, Purolator, Bosch, and K&N. The charcoal filter is highly recommended for its added benefits, especially for drivers in urban or high-traffic areas. Always purchase the filter from a reliable auto parts store or dealership to ensure quality and fit.

​Step-by-Step Guide to Replacing the Cabin Air Filter​

Step 1: Access the Filter Compartment
Open the passenger side door and then open the glove box. Look at the sides of the glove box compartment. You will see a small plastic damper arm on the right side that controls the slow-drop feature. Gently unhook this arm from its post on the glove box bin. Next, you must allow the glove box to open fully. Squeeze the sides of the glove box liner inward. This action releases the stops that hold it in place. Carefully lower the glove box all the way down until it hangs freely. It will now be dangling by its hinge straps, giving you a clear view of the back wall of the dash.

Step 2: Locate and Open the Filter Housing
On the back wall of the dash, you will see a rectangular, black plastic cover. This is the cabin air filter access door. It is approximately 10 inches wide and 4 inches tall. The cover is held in place by two or more Phillips head screws. Using your Phillips screwdriver, remove these screws. Place them in a secure spot, like the glove box bin, so they do not get lost. Once the screws are removed, the cover will be loose. Carefully pull the cover straight toward you. It may be snug. Set the cover aside.

Step 3: Remove the Old Filter
With the cover off, you can now see the old filter. It slides in horizontally. Note the direction of the airflow arrows printed on the side of the filter frame. This indicates the direction air flows through the filter. Use your phone to take a photo of the arrows' orientation for reference. Grip the edges of the old filter and slide it straight out. Be prepared for some loose debris to fall. Inspect the old filter. It will likely be gray or brown, clogged with leaves, dirt, and insects. This is a good opportunity to use a small vacuum hose to clean out the filter chamber, removing any debris that fell in.

Step 4: Install the New Filter
Take your new filter out of its packaging. Compare the airflow arrows on the new filter to the photo you took. It is essential that these arrows point the correct way. For the 2017 F-150, the arrows must point ​DOWN​ and toward the ​REAR​ of the vehicle (toward the firewall). In simpler terms, the arrows should point to the floor and away from the passenger seat. This ensures air flows through the filtering media correctly. Carefully slide the new filter into the chamber, following the guides, making sure it seats flat and even. Do not force it. The fit should be snug but not difficult.

Step 5: Reassemble Everything
Retrieve the plastic access cover. Align it back over the filter opening and press it into place. Reinstall and tighten the Phillips screws securely, but do not overtighten, as you could strip the plastic threads. Now, lift the glove box back into its normal position. Push the sides inward again and swing it up until the stops click into place. Reattach the slow-drop damper arm to its post on the side of the glove box bin. Close the glove box door. The replacement is now complete.

​Testing and Post-Replacement Verification​

After installation, start your truck's engine. Turn the ignition to the "on" position. Turn the HVAC fan to its highest speed. Set the system to draw fresh air from outside, not recirculate. Go to each vent in the cabin and feel the airflow. You should notice an immediate and significant increase in airflow strength compared to before. The air should feel fresh. Any musty odors should begin to dissipate quickly. Allow the system to run for a few minutes. Listen for any unusual noises; the blower motor should sound normal. Test the air conditioning and heating to ensure they are operating effectively. Strong, clean airflow confirms a successful installation.

​Choosing the Right Filter: Standard vs. Charcoal​

When purchasing a replacement, you have two main material choices. The standard particulate filter is made of pleated, non-woven fabric. It effectively captures solid particles like dust, pollen, and mold spores. It is usually the more economical option. The activated charcoal filter incorporates a layer of carbon-impregnated material in addition to the standard particulate layer. The charcoal is treated to be highly porous, creating a massive surface area that adsorbs gases, chemicals, and odors on a molecular level. This includes sulfur dioxide, nitrogen oxides, and hydrocarbons from vehicle exhaust, as well as general environmental odors.

For most drivers, the activated charcoal filter is worth the small additional cost. The benefits are most apparent in city driving, heavy traffic, or near industrial or agricultural areas. It keeps the cabin air noticeably fresher. It is particularly beneficial for individuals with respiratory sensitivities or for those who simply prefer a cleaner cabin environment. Both filter types capture particulate matter equally well, so the charcoal filter provides added functionality without a downside, aside from a slightly higher purchase price. Check your owner's manual; Ford often recommends the charcoal filter (FP-67A) for optimal performance.

​Maintenance Schedule and Professional Service Considerations​

Ford's official maintenance schedule for the 2017 F-150 recommends inspecting the cabin air filter at certain intervals, typically every 20,000 miles under normal driving conditions. "Normal conditions" are defined as mostly highway driving in a dust-free, non-polluted environment. However, very few trucks operate exclusively under these ideal circumstances. Most experts and technicians recommend a more practical schedule: inspect the filter every 15,000 miles or once a year, whichever comes first. Replace it immediately if it appears dirty.

Your actual replacement frequency depends heavily on your driving environment. If you frequently drive on unpaved roads, in heavy construction zones, in areas with high pollen counts, or in stop-and-go city traffic, you should inspect the filter every 10,000 miles or every six months. The same applies if you often use your truck for towing, which can put additional strain on the HVAC system. Keeping a log in your maintenance records is a good practice. Write down the date, mileage, and type of filter installed each time you perform a replacement.

While this is a simple DIY job, you can certainly have it done professionally. A dealership or repair shop will perform the same steps. The cost will be higher due to labor charges and retail parts markup. A typical dealer charge for this service can range from 80 to 120 or higher. Knowing how to do it yourself reduces this cost to just the price of the filter, which is often between 20 and 50. The process empowers you to maintain your vehicle and ensures the job is done correctly and promptly.

​Troubleshooting Common Issues and FAQs​

What if the new filter doesn't seem to fit?
Ensure you have the correct part number for a 2017 F-150. Some model years have subtle changes. Double-check that you are sliding it in straight and that the old filter was completely removed. The arrows must be pointing down and toward the rear.

My HVAC airflow is still weak after replacement. What's wrong?
A still-weak airflow could indicate a separate issue. The blower motor resistor or the blower motor itself could be failing. The ducts or vents could have an obstruction. If you are confident the new filter is installed correctly and airflow is still poor, a professional diagnosis of the HVAC system may be needed.

Can I clean and reuse the cabin air filter?
No. Cabin air filters are designed as disposable, single-use parts. The paper and charcoal media cannot be effectively cleaned without damaging it. Attempting to wash or vacuum it will ruin its filtering capability. Always replace it with a new filter.

Does the 2017 F-150 have a second cabin air filter?
No. The 2017 F-150 has only one cabin air filter, located behind the glove box. Some vehicles have two, but this truck model uses a single-filter system.

Is there a difference for the Raptor or hybrid models?
For the 2017 model year, the cabin air filter location and part are the same across all trim levels and engine types, including the Raptor. The process is identical.
