TL;DR
- The frigidaire-puresource-ultra-2-water-filter fits specific Frigidaire, Frigidaire Gallery, and some Electrolux refrigerators, but the exact fridge model number decides compatibility.
- Replace the filter about every 6 months, or sooner if water flow slows, taste changes, or the filter light turns on, which matches Frigidaire’s standard guidance (Frigidaire, 2026).
- Install the cartridge by seating it fully and twisting until it locks, then flush several gallons of water before drinking or making ice.
- Reset the refrigerator’s filter light after installation so the next reminder starts from zero.
- If the water tastes flat or cloudy right after install, a flush usually fixes it.
What the frigidaire-puresource-ultra-2-water-filter Is and Why It Matters in 2026
The frigidaire-puresource-ultra-2-water-filter is a refrigerator water filter cartridge for compatible Frigidaire-family units. It filters the water that goes to the dispenser and ice maker, which helps reduce common taste and odor issues from household supply water.

This filter is part-number specific, so appearance alone is not enough. Two cartridges can look nearly the same and still use different locking tabs or seals, which is why the refrigerator model number matters first.
The practical job of the filter is simple. It catches unwanted particles and reduces taste problems before water reaches your glass or ice tray.
How to Confirm Compatibility Before You Buy
Compatibility depends on the exact refrigerator model, not just the brand name. The safest check is to match the appliance model number to Frigidaire’s parts documentation or the owner’s manual before ordering a replacement.
Start with the model label inside the refrigerator, often on the side wall, ceiling, or door frame. Then compare that model number with the filter part number listed by Frigidaire for that unit.
Common model families that often use this filter
Many Frigidaire and Frigidaire Gallery refrigerators use the PureSource Ultra 2 format, and some Electrolux models from the same product platform do as well. That family name is only a starting point, not proof of fit.
| Checkpoint | What to look for | Why it matters |
|---|---|---|
| Refrigerator brand | Frigidaire, Frigidaire Gallery, or Electrolux | The filter line is tied to specific product families. |
| Model number | Exact appliance model from the label | Similar fridges can use different cartridges. |
| Filter housing | PureSource Ultra 2 twist-in housing | The housing shape confirms the cartridge style. |
| Owner’s manual | Compatibility and replacement part number | The manual is the final fit check. |
Frigidaire’s support materials are the best source for exact compatibility because part matching can change by model and production run (Frigidaire, 2026). If you cannot confirm the number, do not buy by look or guesswork.

When to Replace the Filter
Replace the filter every 6 months under normal use, or sooner if the flow slows, taste changes, or the indicator light comes on. Frigidaire’s typical replacement cycle is 6 months, which is the standard maintenance interval for this filter type (Frigidaire, 2026).

A filter usually gives warning signs before it stops working well. Lower water pressure, stale-tasting ice, or a return of chlorine taste often means the carbon media inside the cartridge has reached the end of its useful period.
Signs you should change it early
Replace the filter before the 6-month mark if you notice a clear drop in dispenser flow or a return of tap-water taste. Change it as well if the refrigerator says “replace filter,” even when the water still looks normal.
Common replacement triggers include:
- Water dispenses more slowly than it did after installation.
- Ice tastes stale or smells like tap water.
- The filter indicator light is on or flashing.
- You have used the filter for about 6 months.
- The refrigerator sat unused for a long period and the filter dried out.
If your home has heavy sediment, well water, or high water use, the filter may reach its limit sooner. In that case, watch the water flow and taste instead of relying only on the calendar.
How to Install the Filter Correctly
Correct installation means the cartridge is fully seated, locked in place, and leak-free before you use the dispenser. A crooked fit can cause drips, low flow, or a filter that never registers properly.

Before you begin, wash your hands and remove all packaging from the new cartridge. If your fridge uses a bypass plug, remove that plug before inserting the new filter.
Step-by-step installation
- Open the filter compartment, usually inside the fresh-food section near the upper-right area.
- Remove the old filter by turning it counterclockwise or pressing the release, depending on the model.
- Pull the old cartridge straight out.
- Remove the protective cap from the new filter.
- Insert the frigidaire-puresource-ultra-2-water-filter into the housing.
- Turn it clockwise until it locks or stops firmly.
- Close the filter cover, if your model has one.
- Check the dispenser for normal flow and look for leaks around the housing.
The cartridge should feel snug at the end of the twist. If it keeps spinning, stop and remove it, because the tabs may not be lined up correctly.
Common installation errors
The most common mistake is forcing the cartridge in at the wrong angle. That can damage the housing or keep the seal from forming correctly.
Another mistake is leaving the shipping cap on the cartridge. A capped filter will not seat properly, and the dispenser may not work at all.
A slow drip after installation also needs attention. Remove and reinstall the cartridge instead of waiting to see if the leak stops on its own.
How to Flush and Reset the Filter
Flushing and resetting are part of the filter change, not optional extras. Flushing clears carbon dust and trapped air, and resetting tells the refrigerator that a new filter is installed.
How to flush the new filter
Run several gallons of water through the dispenser right after installation. Frigidaire commonly advises flushing until the water runs clear and tastes normal, which also removes loose carbon particles from a new cartridge (Frigidaire, 2026).
Use these steps:
- Place a large container under the water dispenser.
- Dispense water in short cycles until the output looks clear.
- Continue until the flow feels steady and tastes normal.
- Discard the first batch of ice if the refrigerator made ice during the first day.
If the water sputters at first, trapped air is usually the reason, not a bad filter. Keep flushing until the flow steadies.
How to reset the filter indicator
Reset the filter indicator after installation so the refrigerator can track the next replacement cycle. The exact button sequence varies by model, and many Frigidaire units use a filter reset button or a hold-to-reset control on the display panel.
Check your model manual for the exact method, because the button sequence is not universal. If the light stays on after the first reset attempt, repeat the sequence more slowly or unplug the fridge briefly, then try again.
The reset matters because the reminder only works when it starts from zero. Without it, the refrigerator may keep showing an old warning even though the new filter works.
Mistakes to Avoid with the frigidaire-puresource-ultra-2-water-filter
The biggest mistakes are buying the wrong cartridge, skipping the flush, and forgetting the reset. Each one causes a different problem, and all three are easy to avoid.
Buying by appearance instead of model number
A cartridge can look similar and still fail to seal or lock in place. That leads to leaks, weak flow, or a filter that never fits correctly.
Always buy by refrigerator model number and the exact replacement part number. If a seller lists only broad brand names, verify the part against the manual before ordering.
Skipping the flush
A new filter often releases carbon fines and trapped air at first. If you skip the flush, the water can taste dusty or look cloudy for a short time.
Flush the filter until the water clears and the flow steadies. That step is normal setup, not a sign that something is wrong.
Forgetting the reset
If you forget the reset, the warning light may stay on even though the new filter works. That can create confusion later when you try to track the next replacement date.
Reset the indicator right after installation, then note the date on your phone or calendar. A simple reminder still helps a lot.
What Water Taste or Flow Changes Mean After Installation
A short-lived change in taste, cloudiness, or sputtering usually points to air in the line or carbon dust from the new cartridge. Those symptoms often disappear after a proper flush and do not mean the filter is defective.
[IMAGE: A clear glass of water next to a dispenser stream showing normal flow after flushing]
If the water still tastes off after several gallons, check the installation again. A loose fit, unremoved cap, or incorrect cartridge can create the same symptoms as a clogged filter.
Low flow after installation often points to one of three things. The cartridge may not be fully seated, the water line may still have trapped air, or the household supply may already have low pressure.
How Long the Filter Usually Lasts
A typical filter cycle is about 6 months, and that number works for most households using normal water volume. Frigidaire lists 6 months as the usual replacement interval for this filter type (Frigidaire, 2026).
Heavy dispenser use shortens the useful life. Homes that fill a lot of pitchers, bottles, or ice bins may need a new filter earlier than the calendar date suggests.
Water quality also matters. Sediment, mineral buildup, or well water can load the cartridge faster, which means taste and flow are better guideposts than time alone.
FAQ
What refrigerators use the frigidaire-puresource-ultra-2-water-filter?
Compatible refrigerators include Frigidaire, Frigidaire Gallery, and some Electrolux models listed in Frigidaire’s parts documentation. The model number on the appliance label is the final check before you buy.
How often should I replace it?
Replace it every 6 months under normal use, which is Frigidaire’s standard guidance for this filter type (Frigidaire, 2026). If water flow slows or taste changes earlier, replace it sooner.
Do I need to flush a new filter?
Yes. Flushing removes loose carbon particles and trapped air after installation, which helps the water taste normal and flow evenly.
How do I know the filter is installed correctly?
A correct installation feels fully locked in place, does not wiggle, and does not leak at the housing. The dispenser should run normally after a short flush.
Why is the filter light still on after I replaced it?
The refrigerator usually needs a manual reset after filter replacement. Use the reset method in your model’s manual, since Frigidaire uses different button combinations across models.
Can I use the fridge without the filter?
Some models allow a bypass plug, but that depends on the refrigerator design. If you remove the filter, follow the manufacturer’s instructions so the water path stays sealed.
