You’ll want filters that match the same style and model references used by your fridge. On Walmart.com, compatible options often mention these identifiers in the title or details:

• Model match: Look for FPPWFU01, PWF-1, or EPPWFU01 in the listing.
• Install style: Check whether your housing uses a push-in or a twist connection (your owner’s manual can help).
• Dimensions/connectors: Compare length, gasket placement, and connector shape to your current cartridge.
• Certifications: Review NSF/ANSI listings (such as 42, 53, 401, or 372) if those matter to you.
• Model verification: Use your refrigerator’s model number in the product details for extra confirmation.

Multipacks are available if you prefer to stock up for future changes.

Third-party cartridges can be a practical choice when they meet the same fit and performance needs as your original. To compare options effectively:

• Compatibility: Confirm the listing references FPPWFU01/PWF-1/EPPWFU01 and matches your fridge model.
• Certifications: Look for NSF/ANSI marks (42, 53, 401, 372) and read what each covers.
• Capacity/flow: Check stated capacity (some list around 200 gallons) and flow specs in the details.
• Instructions: Follow the installation and priming guidance included with the filter and your appliance manual.
• Documentation: If warranty considerations matter, review your appliance documentation for guidance.

Buying an extra filter can help prevent downtime between changes.

Removal steps can vary by refrigerator, but this general approach may help:

1. Check your manual: Note whether your housing uses a push-in latch or a quarter-turn twist.
2. Prepare: If advised by your manual, shut off water. Dispense a little water to relieve pressure.
3. Open the cover: Gently open the filter compartment.
4. Release: Press the release tab (push-in) or rotate the cartridge counterclockwise (twist) to disengage.
5. Remove: Pull the filter straight out; keep a towel handy for drips.
6. Next steps: When installing a new cartridge, follow the included priming instructions to clear air and carbon fines.

Results can vary by model, so default to your owner’s manual when in doubt.

Timing depends on your water quality, household usage, and your refrigerator’s guidance. A few indicators can help you decide:

• Appliance indicator: Follow your fridge’s filter light or owner’s manual recommendations.
• Taste/flow changes: Replace if you notice new tastes/odors or slower dispensing.
• Capacity: Some compatible options list capacities around 200 gallons; monitor your usage to avoid exceeding that.
• After maintenance: Consider a fresh filter after plumbing work or long storage periods.

Keeping a spare on hand (single- or multi-pack) can make the swap quick. Actual intervals vary, so rely on the product instructions and your appliance’s guidance for the best results.

These NSF/ANSI standards describe the kinds of tests a filter has undergone. In product listings you may see:

• NSF/ANSI 42: Evaluated for aesthetic improvements, like chlorine taste/odor reduction and particulates.
• NSF/ANSI 53: Tested for reduction of certain contaminants; the exact list varies by filter model.
• NSF/ANSI 401: Tested against select emerging compounds (e.g., certain pharmaceuticals or chemicals).
• NSF/ANSI 372: Indicates low-lead materials content.

Always review the product description for the specific claims, the certifying body’s mark, and any documentation. Performance can vary with local water conditions, installation, and maintenance.
