How to Change the Filter on Frigidaire Dehumidifier: A Complete Step-by-Step Guide
Keeping your Frigidaire dehumidifier in top shape doesn’t require a technician or a degree in engineering. One of the easiest and most impactful maintenance tasks you can do is changing the air filter. Over time, the filter collects dust, pet dander, mold spores, and other airborne particles. If left unchanged, a clogged filter can reduce airflow, make your dehumidifier work harder, and even lead to poor indoor air quality.
In this comprehensive guide, you’ll learn exactly how to change the filter on your Frigidaire dehumidifier—no guesswork, no confusion. Whether you’re a first-time user or a seasoned homeowner, we’ll walk you through every step, from identifying your model to installing a new filter and resetting the indicator light. By the end, you’ll feel confident performing this simple task regularly, ensuring your dehumidifier runs efficiently and your home stays comfortable.
Why Changing the Filter Matters
Before diving into the steps, it’s important to understand why this small component plays such a big role. The air filter in your Frigidaire dehumidifier acts like a gatekeeper. As air is drawn into the unit, it passes through the filter, which traps pollutants and moisture-laden particles. This not only protects the internal components—like the evaporator coils and fan—but also ensures the air released back into your room is cleaner and healthier.
A dirty filter restricts airflow, forcing the dehumidifier to run longer cycles to achieve the same level of moisture removal. This increases energy consumption and puts unnecessary stress on the motor. In extreme cases, a severely clogged filter can cause the unit to overheat or trigger safety shut-offs.
Moreover, a neglected filter can become a breeding ground for mold and bacteria, especially in high-humidity environments. When the dehumidifier blows air through a contaminated filter, it can actually worsen indoor air quality instead of improving it.
By changing the filter regularly—typically every 2 to 3 months, or more often if you have pets or live in a dusty area—you’re not just maintaining your appliance. You’re also investing in better air quality, lower energy bills, and a longer lifespan for your dehumidifier.
What You’ll Need
Before you begin, gather the following items to make the process smooth and hassle-free:
- A replacement Frigidaire dehumidifier filter: Always use a genuine or compatible filter designed for your specific model. Check your user manual or the label inside the unit for the correct part number.
- A soft cloth or vacuum with a brush attachment: Useful for cleaning around the filter housing.
- A screwdriver (if required): Some models have screws securing the front panel or filter cover.
- Access to a power outlet: To safely unplug the unit.
- Your user manual: Helpful for locating the filter and understanding model-specific instructions.
Having these items ready will save you time and prevent interruptions during the process.
Step 1: Turn Off and Unplug the Dehumidifier
Safety is always the first priority when working with any electrical appliance. Before you touch anything, make sure your Frigidaire dehumidifier is completely powered down.
Power Down the Unit
Press the power button to turn off the dehumidifier. Wait a few seconds to ensure all internal components have stopped running. This prevents accidental activation while you’re handling the filter.

Unplug from the Wall Outlet
Locate the power cord and gently pull the plug from the wall outlet. Never attempt to change the filter while the unit is still plugged in—even if it’s turned off. Residual power or accidental button presses could pose a risk.
Let the Unit Cool Down (If Recently Used)
If your dehumidifier has been running for several hours, give it 10–15 minutes to cool down. The internal coils and motor may be warm, and handling them too soon could cause discomfort or minor burns.
Taking these precautions ensures a safe and stress-free maintenance experience.
Step 2: Locate the Air Filter
The location of the air filter varies slightly depending on your Frigidaire dehumidifier model, but it’s typically found in one of two places: behind the front grille or under a removable side panel.
Check the Front Grille
Most Frigidaire dehumidifiers have a front-facing air intake grille. This is usually a plastic panel with horizontal or vertical slats. Look for a small latch, tab, or release button near the top or bottom edge. Gently press or slide it to open the grille.
Inspect the Side or Rear Panel
On some models, especially compact or portable units, the filter is accessed from the side or rear. Look for a rectangular cover secured with screws or clips. If you see screws, use a Phillips or flathead screwdriver to remove them before lifting the panel.
Consult Your User Manual
If you’re unsure where the filter is located, refer to your user manual. It will include a diagram showing the exact position and how to access it. You can also find digital copies of most manuals on the Frigidaire website by entering your model number.
Once you’ve located the filter compartment, you’re ready for the next step.
Step 3: Remove the Old Filter
With the access panel open, you should now see the air filter. It’s usually a flat, rectangular mesh or pleated panel made of foam, polyester, or activated carbon.
Slide or Lift the Filter Out
Most filters are designed to slide out easily. Gently pull the filter straight out of its slot. If it feels stuck, wiggle it slightly from side to side—but avoid forcing it, as this could damage the housing.
Note the Filter’s Orientation
Before removing it completely, take a quick look at how the filter is positioned. Some filters have arrows indicating airflow direction (usually pointing toward the unit). Remember this orientation so you can install the new filter correctly.
Inspect the Filter for Dirt and Damage
Hold the old filter up to the light. If it’s dark, clogged with dust, or has visible mold, it’s definitely time for a replacement. Even if it looks somewhat clean, if it’s been in use for 2–3 months, it’s best to replace it to maintain optimal performance.
Dispose of the Old Filter Properly
Place the used filter in a sealed plastic bag before throwing it in the trash. This prevents dust and contaminants from spreading into your home or garbage area.
Now that the old filter is out, it’s time to prepare for the new one.
Step 4: Install the New Filter
Installing a new filter is just as straightforward as removing the old one—just make sure you’re using the right type.
Choose the Correct Replacement Filter
Frigidaire dehumidifiers use specific filter models, often labeled as “AF” (Air Filter) followed by a number (e.g., AF100, AF200). Using the wrong filter can lead to poor fit, reduced efficiency, or even damage to the unit. Always check your model number—usually found on a sticker inside the water tank compartment or on the back of the unit—and match it to the filter part number.
Check the Filter for Damage
Before installing, inspect the new filter for any defects like tears, bent frames, or loose mesh. A damaged filter won’t seal properly and may allow unfiltered air to bypass the system.
Insert the Filter Correctly
Align the new filter with the slot, making sure the airflow arrows (if present) point toward the unit. Slide it in gently until it’s fully seated. It should fit snugly but not require excessive force.
Secure the Access Panel
Once the filter is in place, close the front grille or side panel. Make sure it clicks or locks securely. If you removed screws, reinsert and tighten them—but don’t overtighten, as this could crack the plastic.
With the new filter installed, your dehumidifier is ready to breathe easier.
Step 5: Reset the Filter Indicator Light
Many Frigidaire dehumidifiers come equipped with a filter change indicator light that alerts you when it’s time to replace the filter. After installing a new one, you’ll need to reset this light to stop the alert and restart the timer.
Locate the Reset Button
The reset button is usually found on the control panel, often labeled “Filter Reset,” “Reset,” or represented by a filter icon. It may be a physical button or a touch-sensitive area.
Press and Hold the Reset Button
Press and hold the reset button for 3–5 seconds until the indicator light turns off or changes color. Some models may beep or flash to confirm the reset.
Check the Display
If your dehumidifier has a digital display, look for a confirmation message like “Filter Reset” or “New Filter Installed.” This ensures the system recognizes the change.
Refer to Your Manual if Needed
If the light doesn’t turn off or you’re unsure how to reset it, consult your user manual. Reset procedures can vary slightly between models.
Resetting the indicator ensures you’ll be reminded at the right time for your next filter change.
Step 6: Plug In and Test the Unit
Now that everything is in place, it’s time to power up your dehumidifier and make sure it’s working properly.
Reconnect the Power
Plug the dehumidifier back into the wall outlet. Make sure the cord isn’t pinched or damaged.
Turn On the Unit
Press the power button to turn the dehumidifier on. Set your desired humidity level using the control panel.
Listen and Observe
Listen for normal operation sounds—the fan should run smoothly, and the compressor should engage after a short delay. Check that air is flowing through the front grille and that the filter indicator light remains off.
Monitor for the First Hour
Run the unit for about an hour and check for any unusual noises, reduced airflow, or error messages. If everything looks and sounds good, your filter change was successful.
Troubleshooting Common Issues
Even with careful steps, you might encounter a few hiccups. Here’s how to handle common problems:
Filter Doesn’t Fit Properly
If the new filter is too tight or too loose, double-check the part number. You may have ordered the wrong size. Contact Frigidaire customer support or the retailer for a replacement.
Indicator Light Won’t Turn Off
Ensure the filter is fully inserted and the panel is securely closed. If the light persists, try unplugging the unit for 10 minutes, then plug it back in and reset the filter again.
Reduced Airflow After Replacement
This could mean the filter is installed backward. Open the panel and verify the airflow arrows are pointing toward the unit. Also, check that the filter isn’t compressed or bent.
Unit Makes Unusual Noises
If you hear rattling or grinding, the filter may be loose or misaligned. Turn off the unit, recheck the installation, and ensure nothing is obstructing the fan.
Filter Gets Dirty Too Quickly
If your filter needs replacing every month or less, consider the environment. High dust, pet hair, or mold levels may require more frequent changes. You might also consider using an air purifier in conjunction with your dehumidifier.
Tips for Maintaining Your Dehumidifier
Changing the filter is just one part of keeping your Frigidaire dehumidifier in great condition. Here are a few additional tips to maximize performance and longevity:
- Clean the water tank weekly: Empty and rinse the tank with mild soap and water to prevent mold and bacteria buildup.
- Wipe down the exterior: Use a damp cloth to clean the outside of the unit, especially the air intake and exhaust grilles.
- Check the coils annually: If you’re comfortable doing so, vacuum the evaporator and condenser coils to remove dust and debris.
- Keep the area around the unit clear: Allow at least 6–12 inches of space around the dehumidifier for proper airflow.
- Use a timer or smart plug: Run the dehumidifier during off-peak hours to save energy.
- Store properly during off-seasons: If you don’t use the unit year-round, clean it thoroughly, remove the filter, and store it in a dry place.
