Where the air filter sits and why it matters
The air filter on a Frigidaire refrigerator is usually located inside the fridge compartment, either on the back wall or on the ceiling near the top. Some models place it in the freezer instead. The filter pulls odors and ethylene gas (which speeds spoilage) out of the air, so food stays fresher longer. When it clogs with dust and particles, the refrigerator has to work harder to circulate air, and odors build up.
Replacing it is a five-minute job that costs between $20 and $60 depending on your model. You do not need tools or a technician. The hardest part is finding the right replacement filter for your specific refrigerator, because Frigidaire makes dozens of models and each one takes a different cartridge.
Key Takeaways
- The air filter on most Frigidaire refrigerators sits on the back wall or ceiling of the fridge compartment, though some models place it in the freezer.
- You need your refrigerator's model number to order the correct replacement filter, which you can find on the nameplate inside the fridge or freezer.
- Replacing the filter takes about five minutes and requires no tools — you straightforward slide the old cartridge out and slide the new one in.
- Frigidaire recommends replacing the filter every six months, though the actual timeline depends on how much you use the refrigerator and how dusty your kitchen is.
Finding your model number and the right filter
Before you order a replacement, you need to know which filter your refrigerator uses. Open the refrigerator door and look for a white or silver nameplate, usually on the side wall or the back. Write down the model number — it starts with letters like FFHS, FFTR, or FFSS, followed by numbers.
Go to the Frigidaire parts website or call Frigidaire customer service at 1-800-374-4432 with your model number. They will tell you the exact filter part number. You can also search your model number on Amazon or Lowe's — the correct filter will show up in the results. Do not guess or buy a generic filter; the wrong cartridge will not fit or will not seal properly.
Replacement filters typically cost $25 to $50. Some Frigidaire models use the EAFCBF or PAULTRA cartridge; others use EAFCBF-2 or proprietary designs. The part number matters.
Locating and removing the old filter
Once you have the replacement filter in hand, open your refrigerator door and look for the existing filter. On most Frigidaire models, it is a white or gray plastic cartridge about the size of a soda can, mounted vertically on the back wall near the top or horizontally on the ceiling. Some models hide it behind a cover panel labeled "Air Filter" or "Odor Control."
If there is a cover panel, slide it to the side or unscrew it — usually one or two screws. The filter itself typically slides straight out toward you. Grip it firmly and pull; it should come free without resistance. If it is stuck, do not force it. Wiggle it gently side to side while pulling, or check whether a clip or latch is holding it in place.
Once the old filter is out, look at the slot or housing where it sat. You may see dust or debris. Wipe the area clean with a dry cloth so the new filter seats properly.
Installing the new filter
Check the new filter for any plastic tabs or protective caps. Remove them if present. Look at the end of the filter — most Frigidaire filters have an arrow printed on them showing the direction of airflow. The arrow should point into the refrigerator, away from you.
Slide the new filter into the slot, pushing it straight in until it clicks or seats fully. You should feel or hear a small click when it locks into place. If your model has a cover panel, slide it back on or screw it closed. Close the refrigerator door.
Some Frigidaire models have a filter indicator light on the control panel. If yours does, the light may stay on for a few minutes after you install the new filter, then turn off automatically. If it stays on after 24 hours, check the Frigidaire manual for your model — a few older units require you to manually reset the light by holding a button for three seconds.
When to replace the filter and what to watch for
Frigidaire recommends replacing the air filter every six months. If you have a large household, cook frequently, or live in a dusty area, you may need to replace it more often — every three to four months. If you live alone and rarely cook, it may last longer.
Signs that a filter needs replacement include odors that do not go away even after you clean the fridge, visible dust or discoloration on the filter itself, or reduced airflow (you may notice the fridge is not cooling as evenly). If you cannot see the filter easily, you can remove it and hold it up to a light — a clogged filter will look dark or gray instead of white.
Keep the old filter box or note the part number somewhere so you can reorder the same one next time. Filters are not returnable, so order only when you are ready to install.
Troubleshooting if the new filter does not fit
If the new filter will not slide in or does not seat properly, stop and check three things. First, confirm you ordered the correct part number for your model — call Frigidaire again if you are unsure. Second, make sure you removed any plastic protective caps or tabs from the new filter. Third, check that you are inserting it in the right direction and orientation; some filters are rectangular and only fit one way.
If the filter is the right one and you have removed all protective materials, but it still will not fit, the housing may be damaged or misaligned. Contact Frigidaire customer service with your model number and describe what is happening. They may send a replacement housing or recommend a repair technician.
Frequently Asked Questions
Can I use a generic or third-party air filter instead of a Frigidaire brand filter?
Generic filters may fit physically, but they often do not seal properly or filter as effectively. Frigidaire designs its housings for specific cartridge dimensions and airflow patterns. Using the wrong filter can reduce cooling performance or allow odors to bypass the filter. Stick with the Frigidaire part number for your model.
What do I do if I cannot find the filter in my refrigerator?
Not all Frigidaire models have air filters — some rely on charcoal in the freezer compartment instead. Check your refrigerator manual or call Frigidaire with your model number. They will tell you whether your model has a replaceable air filter and where it is located.
Does the refrigerator need to be unplugged before I replace the filter?
No. The air filter is not connected to any electrical components. You can replace it while the refrigerator is running. Unplugging is not necessary and will cause the fridge to warm up unnecessarily.
How much does a replacement air filter cost?
Frigidaire air filters typically range from $25 to $50, depending on the model and where you buy it. Ordering directly from Frigidaire or through authorized retailers is usually more expensive than buying through Amazon or Lowe's, but the filter is the same.
Will replacing the air filter improve cooling if my fridge is not cold enough?
A clogged air filter can reduce airflow and make cooling uneven, so replacing it may help. However, if the refrigerator is not cold enough overall, the problem is usually the compressor, thermostat, or refrigerant — not the air filter. If replacing the filter does not improve cooling within a day, contact a repair technician.
