A refrigerator filter purchase can go wrong before price even enters the picture: an air filter and a water filter serve different jobs, and water-filter model references are not interchangeable. This guide separates the four options by filter type, compatible naming, pack format, and listed price so you can focus on the replacement that fits your refrigerator's filter category.
Quick take
The 6 Pack Refrigerator Air Filter Replacement for FRGPAAF2 Frigidaire PureAir AF is the distinct choice for refrigerator air filtration and is also the lowest-priced option at $11.18. The other three are refrigerator water filters using carbon/charcoal filtration and chlorine taste-and-odor removal.
For water filtration, the key divider is the identifier on your existing filter system. The EPTWFU01 Water Filter Replacement is centered on Frigidaire EPTWFU01, EWF02, and Pure Source Ultra II references. The KAD3RXD1, WHR3RXD1, W101211416 Water Filter Replacement centers on those model codes. The Kenmore 9911 Replacement Refrigerator Water Filter 46-9911 is the single-filter alternative for the 9911, PureSource2 WF2CB, and EWF2CBPA PureAdvantage references.
Listed price comparison
| Option | Format | Listed price | Relative position |
|---|---|---|---|
| EPTWFU01 Water Filter Replacement | 6-pack water filter | $25.49 | |
| KAD3RXD1, WHR3RXD1, W101211416 Water Filter Replacement | 6-pack water filter | $22.49 | |
| FRGPAAF2 Frigidaire PureAir AF Replacement | 6-pack air filter | $11.18 | |
| Kenmore 9911 Replacement Water Filter 46-9911 | 1-pack water filter | $19.49 |
The listed range runs from $11.18 to $25.49, a spread of $14.31. Because the lowest-priced choice is an air filter, compare it with the water-filter choices only when your refrigerator uses an air-filter format.
Decision matrix
- For refrigerator air treatment: Select the FRGPAAF2 / PureAir AF replacement. Its pleated construction and refrigerator-device designation put it in a different category from the water filters.
- For EPTWFU01 or EWF02 naming: Choose the EPTWFU01 water-filter pack. Its compatible-model references include EPTWFU01, EWF02, and Pure Source Ultra II.
- For KAD3RXD1, WHR3RXD1, or W101211416 naming: Choose the corresponding six-pack water filter. Those identifiers appear directly in its title and compatible-model list.
- For 9911, WF2CB, or EWF2CBPA naming: Choose the Kenmore 9911 option. It is the only one here with those specific references and a stated 500-gallon capacity.
Product notes
EPTWFU01 Water Filter Replacement for Frigidaire
This six-pack is the focused water-filter option for refrigerators using EPTWFU01, EWF02, or Pure Source Ultra II references. It uses carbon/charcoal filtration and is described for chlorine taste and odor reduction, giving it a clear role among the water-filter choices. At $25.49, it has the highest listed price in this comparison, but it also supplies six replacement filters in the stated format. Pick it when the EPTWFU01-style identifier is the one that matters for your refrigerator. Its limitation is equally clear: the description identifies it as a compatible alternative rather than an OEM product, and it is not the choice for a FRGPAAF2 refrigerator air-filter compartment.
KAD3RXD1, WHR3RXD1, W101211416 Water Filter Replacement
The appeal of this $22.49 option is its direct alignment with KAD3RXD1, WHR3RXD1, and W101211416 model references. It is a six-pack water-filter format with carbon/charcoal filtration and chlorine taste-and-odor removal listed, making it suited to households replacing this specific family of water filters over time. The title and compatible-model line also include 46-9083, 46-9030, W10177635, and W1018666. Choose it when those codes define your replacement need rather than a Frigidaire EPTWFU01 reference. The trade-off is model specificity: it is not positioned as the pick for the EPTWFU01 or Kenmore 9911 filter formats.
FRGPAAF2 Frigidaire PureAir AF Replacement
At $11.18, this is the lowest listed-price option and the only refrigerator air filter in the group. The six-pack uses pleated construction, is designated for refrigerator use, and is described as an FRGPAAF2 / PureAir AF-2 replacement. Its description also identifies coconut-shell activated carbon material for absorbing refrigerator food odors. Choose it for a refrigerator that takes the FRGPAAF2 PureAir AF-style air filter, especially if you want several air-filter replacements in one format. The boundary is simple: this is an air filter, not a water filter for a refrigerator dispenser or ice maker, so it does not replace any of the three water-filter options here.
Kenmore 9911 Replacement Refrigerator Water Filter 46-9911
The Kenmore 9911 is the right fit-oriented choice for shoppers seeking 9911, PureSource2 WF2CB, or EWF2CBPA PureAdvantage references. It is a carbon/charcoal refrigerator water filter with a stated 500-gallon capacity and chlorine taste-and-odor removal among its listed functions. At $19.49, it sits between the air-filter option and the two six-pack water-filter options on listed price. Choose it when you want the 46-9911 format and its corresponding compatibility references. Its main limitation is pack format: this listing is for one filter, while the EPTWFU01 and KAD3RXD1-style water filters are each offered as six-packs.
Final recommendations by use case
Choose the FRGPAAF2 Frigidaire PureAir AF Replacement for a refrigerator air-filter replacement. For water filtration, choose the EPTWFU01 Water Filter Replacement when EPTWFU01, EWF02, or Pure Source Ultra II is your reference; choose the KAD3RXD1, WHR3RXD1, W101211416 Water Filter Replacement for those model codes; and choose the Kenmore 9911 Replacement Refrigerator Water Filter 46-9911 for the 9911, WF2CB, or EWF2CBPA format. The strongest decision rule is to match filter type first, then match the refrigerator's filter identifier.
