Clearer-tasting water starts with the right replacement
A sharp chlorine note can make a cold glass from the refrigerator less appealing, even if the water looks perfectly clear. The right replacement cartridge can help improve taste and reduce certain listed impurities, but it has to match your refrigerator’s filter system. That compatibility check is the first step in finding the best frigidaire refrigerator water filter for your kitchen, not simply picking the cartridge with the broadest-sounding claims.
This roundup compares three Frigidaire options by their stated features, installation style, and available certification information. The EPTWFU01 uses carbon-based filtration and a push-and-twist fit; the ULTRAWF is listed for compatible PureSource Ultra systems and includes a priming step after installation. The FPPWFU01 listing identifies it as a PurePour PWF-1 filter, but gives fewer performance details, so check your refrigerator manual before ordering. Manufacturer claims about contaminant reduction apply to the specific filter and conditions described in its performance data sheet, not automatically to every household water concern.

If you’re replacing an older cartridge, this practical guide explains how to remove an old water filter. The picks below focus on the details that matter at the fridge: model fit, taste and odor claims, installation, and the reminder reset process.
Pros
- Effectively reduces common tap water impurities, providing cleaner water for drinking and cooking at camp
- Easy installation with no tools required - just push and click
- Compact design fits seamlessly in Frigidaire refrigerators, including many RV models
Cons
- Only compatible with Frigidaire refrigerators using the PureSource Ultra system, limiting portability
- Requires replacement every 6 months, adding ongoing cost for frequent campers
- Not a portable solution for backcountry use; best used at home or in an RV with the right fridge
When you're out camping, whether in an RV or at a family campsite, clean drinking water is non-negotiable. The Frigidaire PureSource Ultra ULTRAWF water filter is designed for Frigidaire refrigerators with the PureSource Ultra system, making it an excellent choice for RV campers who have this fridge model. It also works well for family campers who want to pre-filter water at home before filling their camping water containers. This filter is all about removing the stuff you don't want in your water - like lead, nitrates, pesticides, and mercury - so you can enjoy fresh-tasting water without worry.
Many campers may prefer using this filter for their RV refrigerator's water dispenser or icemaker. The carbon-based filter does a solid job of reducing chlorine taste and odor, which can be a big plus if you're used to tap water that smells like a swimming pool. According to product specifications, it's certified by NSF International against standards 42, 53, and 401, so you can trust that it's been tested for contaminant reduction. Some users find that the water tastes noticeably cleaner, especially when filling up their hydration bladders or bottles for a day hike.
Installation is straightforward - you push the release button to remove the old filter, slide the new one in until it clicks, then run water for three minutes to prime it. That's it. No tools, no plumber. Just be aware that the filter's 6-month reminder light doesn't reset automatically; you'll need to press and hold the Water Filter button on your dispenser panel for three seconds until the light changes from red to green. It's a minor step but easy to forget.
In terms of build quality, the ULTRAWF feels sturdy and well-made. It's compact - about 2.2 x 2.4 x 11.2 inches - and weighs just over half a pound. The water quality association has certified it for sustainability under WQA/ASPE/ANSI S 803, which is a nice bonus for eco-conscious campers. However, this filter is not a portable solution for backpacking or tent camping. It's designed specifically for Frigidaire refrigerators, so if you don't have one in your RV or home, it won't work.
One realistic limitation is that you'll need to replace this filter every six months. For frequent campers, that's a recurring cost. But considering the peace of mind from reduced contaminants and better-tasting water, many users find it worthwhile. The filter also doesn't improve water pressure or flow rate - it simply filters what's already coming through your fridge line.
If you're a weekend warrior with a Frigidaire fridge in your RV, or a family camper who likes to start with clean water at home, the Frigidaire PureSource Ultra ULTRAWF is a practical choice. It's not a backcountry filter, but it does exactly what it's supposed to do for your home or RV setup. For campers who prioritize water quality and convenience, this filter is a solid investment.
FAQs
How do I know which Frigidaire refrigerator filter fits?
Check your refrigerator’s model number and manual before buying. EPTWFU01, FPPWFU01 PWF-1, and ULTRAWF are different cartridges, and a similar-looking filter may not fit your system. Match the replacement number exactly.
Can these filters reduce chlorine taste and odor?
Yes, the EPTWFU01 and ULTRAWF descriptions state that their carbon-based filtration helps reduce chlorine taste or odor. The supplied FPPWFU01 description does not detail contaminant reduction, so consult its current product documentation for specific claims.
Do refrigerator filters remove lead, nitrates, or mercury?
The EPTWFU01 description lists reduction of lead, nitrates, and mercury, while the ULTRAWF description also lists pesticides. Check each cartridge’s performance data sheet for the exact claims and conditions, and use a water test if you need to address a known contaminant.
What certifications are listed for the ULTRAWF filter?
The product information states that the ULTRAWF is tested and certified by NSF International against NSF/ANSI Standards 42, 53, and 401. Verify the current performance data sheet for the specific reduction claims associated with those standards.
How do I install and prime the ULTRAWF cartridge?
Push the old filter to release it, then press the new cartridge into place until it clicks. The listed instructions say to run water through the new filter for three minutes and discard it to clear harmless air and carbon particles.
Why is my refrigerator filter light still on after replacement?
The reminder light may need a manual reset. Many listed Frigidaire models reset by holding the Water Filter button for three seconds, but your refrigerator’s Use and Care Manual takes priority if the control process differs.
Can a refrigerator cartridge replace a whole-house or well-water filter?
No, a refrigerator cartridge treats water at the refrigerator dispenser and is not a substitute for a whole-house system or a well-water treatment plan. For setup considerations beyond the fridge, review this guide to installing an inline water filter, while confirming that the equipment suits your water source.
