How to Replace Air Filter on Frigidaire Refrigerator: A Complete, Step-by-Step Guide

Replacing the air filter in your Frigidaire refrigerator is a quick, essential maintenance task that requires no tools and takes only a few minutes. Locate your filter compartment (typically top-right inside the fresh food section or behind the base grille), remove the old filter by pressing the release button or turning it counterclockwise, unpack the new genuine Frigidaire filter, insert it correctly until it clicks or seats firmly, reset the filter light if your model has one, and close the compartment. Performing this simple procedure every 6 months ensures fresh-tasting food, eliminates odors, and maintains optimal fridge performance. Here’s exactly how to do it on any Frigidaire model.

Why Replacing Your Frigidaire Refrigerator Air Filter Matters
Frigidaire refrigerator air filters are engineered to actively purify the air circulating inside the fresh food compartment. Their activated carbon core captures and neutralizes food odors – from pungent cheeses to forgotten leftovers – preventing smells from permeating other items. Simultaneously, they trap microscopic particles like dust and spores, contributing to a cleaner internal environment. Neglecting regular replacement means the carbon becomes saturated. Odors linger, food absorbs unwanted smells faster, and the filter’s effectiveness plummets. Regular replacement isn't optional; it's critical for preserving food quality, extending freshness, and ensuring your refrigerator operates as designed. Frigidaire universally recommends changing the filter every six months.

Understanding Frigidaire Air Filter Types
Frigidaire uses different filter types and technologies across its various refrigerator models. Correct identification is the first step:

  1. PureSource Ultra Air Filter (Most Common): This is the standard activated carbon air filter found in the majority of Frigidaire French door and side-by-side models manufactured within the last decade. It targets odors. Look for model numbers starting AIR-XXXX (e.g., AIR-20X, AIR-30X, AIR-35X). It fits into a dedicated filter compartment inside the fridge.
  2. PureSource Ultra Air & Water Filter (Combination): Found in select high-end French door models with water/ice dispensers, this dual-purpose filter replaces both the internal air filter and the water filter. It handles odors and contaminants in the water supply. Model numbers start with WF-XXXX (e.g., WF-3CB, WF-3SC). Its location varies significantly, typically outside the fresh food compartment, often behind the bottom grille.
  3. OdorFresh Air Filter (Older Models): Primarily installed in older Frigidaire top-freezer or bottom-freezer models. These are usually smaller round or cylindrical filters focusing solely on odor control. Model numbers start AIR-XXXX, but older prefixes like AIRx were used. Location is almost always inside the fresh food compartment, often clipped to the back wall or ceiling.
  4. Water Filters Only: Important distinction: Standard water filters (e.g., ULTRAWF, ULTRAWF2, Puresource 2 & 3 filters starting with WF) only affect water and ice quality. They do not impact air quality inside the refrigerator. Do not confuse these with air filters or combination air/water filters.

Locating Your Specific Frigidaire Air Filter Compartment
Filter placement varies dramatically by Frigidaire refrigerator style and model year. Here’s a breakdown:

  • Modern French Door & Side-by-Side Refrigerators (PureSource Ultra Air Filter):
    • Most Common: Inside the refrigerator's fresh food compartment, almost always near the top right corner.
    • Identify: Look for a rectangular or square panel on the inner ceiling or upper sidewall.
    • Access: Gently push up on the release latch/button marked "Filter" or "Push", and the door should swing down. The filter slot is revealed behind this panel.
  • French Door Models with Water/Ice Dispenser & PureSource Ultra Air & Water Filter:
    • Location: Outside the main compartments. Behind the kickplate grille at the bottom front of the refrigerator.
    • Access: Grasp the grille firmly and pull straight outwards to release it (some models may have retaining screws). Look for the filter housing near the center or slightly to one side.
  • Top-Freezer and Bottom-Freezer Models (Often OdorFresh Filters):
    • Location: Inside the fresh food compartment.
    • Possible Spots: Mounted on the rear wall (look for a round or rectangular cover), clipped to the ceiling, near the top-back corner, or sometimes within a small compartment on the side wall. It's usually visible upon opening the door.
  • Finding Your Exact Model Information:
    • Model Tag Locations: The crucial model number sticker is typically inside the refrigerator. Check:
      • The left sidewall near the top shelf.
      • The ceiling of the compartment.
      • Inside the door bins (especially the top left).
      • Occasionally, on the door frame.
    • Cross-Reference: Once you have your model number (e.g., FG4H2277UF), search Frigidaire's official parts site or major online retailers for replacement air filters compatible with that exact model.

Step-by-Step: Removing the Old Frigidaire Air Filter
Armed with the correct new filter, removal is straightforward:

  1. Identify the Compartment: Based on your filter type and location guide above.
  2. Access the Housing:
    • Internal Compartment (Air Filter only): Find the small panel on the ceiling or wall. Push the marked button or gently lift/push on the designated spot to release the door. It will swing down.
    • External Compartment (Combination Air/Water filter): Carefully pull the base grille straight out from the bottom front of the fridge. Set it aside safely.
  3. Remove the Old Filter:
    • PureSource Ultra Air Filter: Look into the revealed slot. You'll see the end of the filter cartridge. Firmly press the eject button or tab located just above or below the filter head. The filter will partially spring out. Grasp it and pull straight down to remove it completely.
    • Combination Air/Water Filter: Locate the filter housing (a large cylindrical knob near the front or side bottom). Push the large eject button on the housing firmly. Turn the filter knob about a 1/4 turn counterclockwise until it stops. Pull the filter knob straight out towards you.
    • Older OdorFresh Filters: If covered by a panel, pop it off (clips usually hold it). Grasp the filter body firmly and either twist it counterclockwise about 90 degrees or pull it straight downwards, depending on the style. It should release.
  4. Discard Properly: Place the old filter in your regular household trash. It contains saturated carbon, so do not attempt to wash or reuse it.

Preparing & Installing the New Frigidaire Air Filter
Avoid rushing this step – correct installation is key:

  1. Unpack Thoroughly: Remove the new filter from its plastic retail packaging. Look for any clear plastic shipping protectors or stickers on the filter itself, especially over the inlet/outlet ports. Remove all protective materials, film, stickers, or tape. If any seal remains, water or air won't flow correctly. Inspect the o-rings (if present) for damage.
  2. Identify Insertion Direction: Frigidaire filters have a specific flow direction.
    • PureSource Ultra Air Filter: Look for arrows molded into the filter casing. These arrows point downward towards the floor when installed inside the fridge compartment.
    • Combination Air/Water Filter: Arrows on the filter body or knob should point towards the rear of the housing when inserted correctly. The knob usually has text reading "FRONT".
  3. Align and Insert:
    • Internal Air Filter: Position the new filter with the arrows pointing down. Tilt the filter slightly (front end slightly higher) and slide its top end into the slot at the back. Push it firmly but gently upward and backward into the housing until you feel it bottom out or fully seat. Now, push the bottom end firmly upwards until you hear a distinct click. The filter head should be flush with the surrounding housing.
    • Combination Filter: Align the knob so "FRONT" is facing forward and arrows point to the back. Insert the filter cartridge straight into the housing opening. Push it firmly all the way in. Once fully seated, turn the knob clockwise about a 1/4 turn until it stops, locking it in place.
    • Older OdorFresh: Align any tabs or notches. Insert the filter straight into its holder and push up firmly until it clicks/clips in place, or turn clockwise if it twists.
  4. Close the Compartment:
    • Internal: Swing the compartment door back up until it clicks securely into its closed position.
    • External: Reattach the base grille by aligning its tabs with the slots on the refrigerator frame and pushing firmly until it snaps back into place.

Resetting the Frigidaire "Replace Filter" Indicator Light
Many Frigidaire refrigerators feature a light or notification to remind you when filter replacement is due (typically every 6 months). This light may illuminate earlier than 6 months based on door openings. Replacing the filter does NOT automatically turn this light off; you must manually reset it.

  1. Locate the Reset Button: This is usually near the light itself on the dispenser control panel or inside the control display. Look for a button labeled "Filter Reset," "Reset," or an icon resembling a water droplet or filter. Sometimes pressing and holding a specific combination of buttons (like "Light" or "Lock") for several seconds is required. Consulting your owner's manual is always the most accurate way, as location varies significantly.
  2. Press and Hold: Once located, press and hold the designated reset button. Hold it for approximately 3-8 seconds. You'll typically get audible feedback (a beep) and the light will turn off.
  3. Verification: Release the button. The "Replace Filter" or similar indicator light should now be off. If it stays on, repeat the process, ensuring you hold the button long enough. If problems persist, confirm you installed the correct filter and all protective packaging was removed, then try resetting again.

Troubleshooting Common Frigidaire Air Filter Issues
Even a simple task can have snags. Here's how to handle them:

  • Filter Won't Seat/Click In:
    • Misalignment: Double-check alignment and direction arrows. Try rotating the filter slightly while pushing. Ensure no packaging debris obstructs the slot.
    • Wrong Filter: Triple-check the model number compatibility. An incompatible filter won't fit properly.
    • Internal Obstruction: Visually inspect the slot for any packaging remnants or foreign objects blocking insertion.
  • Filter Compartment Door Won't Close After Installation:
    • Filter Protrusion: Reopen, eject the filter, and re-seat it firmly, ensuring it clicks fully into position and the head is flush.
    • Compartment Jam: Ensure no components inside the housing are bent or broken preventing the door from latching.
  • "Replace Filter" Light Won't Reset:
    • Holding Time: Hold the reset button longer (up to 10 seconds). Consult your manual for the exact procedure.
    • Power Cycle: Unplug the refrigerator for 60 seconds, then plug it back in. Attempt the reset procedure after it powers back up.
    • Correct Filter Installed? Confirm the filter model is exact and packaging film is removed.
    • Control Lock: Ensure the refrigerator's control panel is unlocked during the reset attempt.
  • Strong Odors Persist After Replacement:
    • Run Time: Allow 24 hours for the new carbon to fully activate and start absorbing odors effectively.
    • Spill Source: Clean any visible spills or spoiled food inside the refrigerator. An air filter won't overcome major contamination sources.
    • Thorough Cleaning: Wash removable shelves, bins, and interior walls with warm water and baking soda.
  • Water Flow Issues (Combination Filters Only):
    • Flushing: Dispense 1-2 gallons of water through the dispenser to flush air from the system and purge initial carbon fines from the new filter.
    • Reset Check: Ensure you reset the water filter indicator specifically (some models require this separately from the air filter reset).
    • Seal Removal: Confirm absolutely all protective film and stickers were removed from the filter ports before installation.

Maintaining Peak Performance: Air Filter Best Practices
Replacement every six months is essential, but consider these additional tips:

  • Set Reminders: Mark the replacement date on your calendar or set a phone alert 6 months from installation. Sticker the installation date on the new filter as a reminder.
  • Buy Genuine Frigidaire Filters: While third-party alternatives exist, Frigidaire OEM filters guarantee precise fit, filter media designed specifically for their systems, and reliable performance. Non-genuine filters risk poor fit (leaking/damage), less effective filtration, and potential incompatibility with filter reset systems.
  • Record Your Model Number: Write down your refrigerator's model number in a permanent place (like your phone notes) for easy reference when reordering. Also record the specific filter part number that worked.
  • Pre-Purchase: If replacing both air and water filters separately, ensure you have the correct part numbers for both. Don't assume they are the same.
  • Avoid Impact: Handle the new filter carefully, especially the edges and ports. Damaged filters won't seal correctly.
  • Clean Compartment: While changing the filter, take a moment to wipe out the filter compartment door or base grille area to remove dust.
  • Check Annually: If you haven't changed the filter in over 6 months, check it. Heavy usage might warrant more frequent changes.

Following these detailed steps ensures replacing your Frigidaire refrigerator air filter is quick, successful, and keeps your food smelling fresh and tasting great for the next six months. Consistent filter maintenance is a small investment that delivers significant benefits for your appliance’s performance and the quality of your stored food.
