How to Replace the Frigidaire EPTWFU01 Water Filter in 3 Easy Steps

If you own a Frigidaire refrigerator that uses the EPTWFU01 filter, replacing it regularly is essential for clean, fresh-tasting water and ice. The EPTWFU01 filter helps reduce contaminants like chlorine, lead, and pharmaceuticals ensuring your family drinks water you can trust.
In this guide, we’ll walk you through how to replace the EPTWFU01 water filter in just 3 easy steps, even if it’s your first time. Let’s get started.
Why You Should Replace Your EPTWFU01 Filter Every 6 Months
Many homeowners underestimate how critical water filters are to both appliance health and personal health. Over time, the filter media becomes clogged with:
- Chlorine and chloramine
- Lead and heavy metals
- VOCs and organic contaminants
- Cysts, turbidity, and sediment
As the filter reaches the end of its lifespan, these substances are no longer effectively removed. Frigidaire recommends replacing the filter every 6 months or 200 gallons, whichever comes first, to:
- Prevent bacterial buildup
- Maintain optimal water pressure
- Ensure ice cubes remain odor-free
- Avoid damage to internal water lines
If your household uses water heavily (e.g. for cooking, babies, or pets), more frequent replacements may be necessary.
🛠 What You’ll Need
Replacing your filter doesn’t require any tools, it’s designed to be a simple twist-and-lock operation. However, we recommend preparing:
- A new Frigidaire EPTWFU01 water filter (NSF certified)
- A dry towel or paper towels for any small leaks
- (Optional) Your refrigerator manual for exact housing location
- (Optional) A timer or reminder app to set a 6-month replacement alert
If you’ve purchased a compatible generic filter (rather than OEM), ensure it’s tested against NSF/ANSI 42 & 53 standards for safety and performance.
🔧 Step 1: Locate the Filter Compartment
Open your refrigerator and find the filter housing.
It’s usually located in one of these spots:
- Upper right corner of the refrigerator interior
- Top rear of the fridge
- Behind a small plastic cover that pops open
On most Frigidaire French-door and side-by-side models, the EPTWFU01 filter is mounted vertically, near the top-right corner.
🔄 Step 2: Remove the Old Filter
Once you've located the filter compartment:
- Open the housing door if applicable. This might pop down automatically.
- Grip the exposed filter head and rotate it counter-clockwise (left) until it unlocks.
- Gently pull the filter out.
- Dispose of the used filter according to local recycling rules. Some components are recyclable.
🧠 Note: If the filter is stuck, don’t force it, give it a gentle wiggle. You may also need to reduce internal water pressure by turning off the water supply briefly.
Step 3: Install the New EPTWFU01 Filter
Here’s how to install the new filter correctly:
- Remove any protective caps from the new filter.
- Insert the new filter into the housing with the arrow facing upward or following the alignment tabs.
- Rotate clockwise (right) until the filter clicks or locks into place.
- Close the filter housing door securely.
📲 After installation:
- On electronic models, press and hold the “Water Filter” or “Reset” button on the fridge control panel for 3–5 seconds to clear the alert.
- If your model doesn't have a reset button, consult your manual, some require a sequence using the Ice or Light buttons.
💡 Bonus Tip: Flush the System
Run 2–3 gallons of water through the new filter (usually via the water dispenser) to remove any carbon dust and air bubbles.
This ensures:
- Clear water
- No cloudy appearance
- Better taste from the first glass
