A refrigerator water filter is a model-number purchase before it is a price purchase. UKF8001, 9911, and KAD3RXD1/WHR3RXD1 identify different replacement paths, so the useful choice is the filter that aligns with the code your refrigerator uses-and then with whether you want one filter or a multi-pack.
Quick take
For Maytag UKF8001 or Filter 4 model references, the RedyPure replacement and the IcePure three-piece option are the two direct fits to consider. RedyPure carries the lowest listed price in this group, while IcePure is explicitly titled as a three-piece option. The Kenmore 9911 is the focused pick for 9911, PureSource2 WF2CB, or EWF2CBPA PureAdvantage references, with a stated 500-gallon capacity. The six-pack replacement belongs in a separate lane: its title centers on KAD3RXD1, WHR3RXD1, and W101211416 part numbers.
The listed prices span USD 9.93 to USD 27.99, a USD 18.06 spread. All four options list chlorine taste and odor among their contaminant-removal claims, so model-family alignment and pack format create the clearest distinctions.

Product notes
RedyPure Maytag UKF8001 / Filter 4 Replacement
The RedyPure Refrigerator Water Filter Fit For Maytag 4396395 UKF8001 UKF8001AXX-200 UKF9001 is the logical starting point for a Maytag, Whirlpool, Amana, Jenn-Air, or KitchenAid replacement search that uses the listed UKF8001, Filter 4, 4396395, or OWF50 references. Its USD 9.93 listed price makes it the lowest-priced option here, and it states a 300-gallon capacity, NSF42 certification, and carbon/charcoal filtration. It also lists chlorine taste and odor removal. The tradeoff is capacity: the stated 300 gallons is below the 500-gallon figure listed for the Kenmore 9911. Pick RedyPure when the compatible-model string aligns and a lower upfront listed price matters most.
6 pack Refrigerator Water Filter Replacement for KAD3RXD1, WHR3RXD1, W101211416
The 6 pack Refrigerator water filter Replacement for KAD3RXD1, WHR3RXD1, W101211416 is tailored to shoppers who recognize those part numbers and want a six-pack format. At USD 22.49, the listed package combines multiple replacements with carbon/charcoal filtration and a chlorine taste and odor claim. The description also identifies it as a compatible replacement rather than an OEM product. Its key limitation is that it occupies a different model-code lane from the UKF8001 and 9911 options: the title is built around KAD3RXD1, WHR3RXD1, and W101211416 instead. Choose it when those codes match your replacement reference and a six-pack is more suitable than the listed one-pack or three-piece alternatives.
Kenmore 9911 Replacement Refrigerator Water Filter 46-9911
The 1 PACK Kenmore 9911 Replacement Refrigerator Water Filter 46-9911 New, USA is the dedicated choice for refrigerators using the 9911, PureSource2 WF2CB, or EWF2CBPA PureAdvantage references named in its compatibility details. Its USD 19.49 listed price sits between the lowest-priced RedyPure filter and the six-pack or three-piece alternatives. The standout specification is a stated 500-gallon capacity, compared with the 300-gallon capacities listed for the two UKF8001-oriented choices. Kenmore also identifies chlorine taste and odor removal and carbon/charcoal filtration. The limitation is clear from the title: this is a 1 PACK 9911 replacement, not an option labeled for UKF8001/Filter 4 or KAD3RXD1/WHR3RXD1.
IcePure Maytag UKF8001 Filter 4 Water Filter 3 PCS
IcePure's Fit For Maytag UKF8001 Filter 4 UKF8001AXX-750 UKF8001AXX-200 Water Filter 3 PCS is the multi-filter Maytag-centered choice. The title explicitly combines UKF8001, Filter 4, UKF8001AXX-750, and UKF8001AXX-200 references with a three-piece count. It lists a 300-gallon capacity, NSF 42 certification, and chlorine taste and odor removal, while the longer compatibility description also includes EDR4RXD1 among its replacement references. At USD 27.99, it is the highest listed price in the comparison. That makes the three-piece format the central reason to select it rather than its individual listed price. Choose IcePure when the stated Maytag/Filter 4 identification fits and three filters suit your planned replacement quantity.
Final recommendation by use case
Choose RedyPure for a UKF8001 or Filter 4 replacement with the lowest listed price. Choose IcePure when that same Maytag-oriented filter family is right and you specifically want the three-piece format. Choose Kenmore 9911 for the 9911, WF2CB, or EWF2CBPA replacement family and its stated 500-gallon capacity. Choose the six-pack KAD3RXD1/WHR3RXD1/W101211416 replacement when those exact title codes are the ones you are replacing and six filters fit your needs.
