Overview
A three-pack of NSF-certified refrigerator water filters designed as a direct replacement for the Whirlpool/Filter 4/UKF8001 family, rated to 0.5 microns using coconut shell carbon.
This is a compatibility replacement part, not a refrigerator itself, so the fit list is the page's most useful content. SpiroPure lists it as an equivalent for UKF8001, Filter 4, EDR4RXD1 and Puriclean II part numbers, and names specific Whirlpool, Bosch and Kenmore refrigerator models it's built to fit. It carries NSF/ANSI 42 certification for chlorine taste and odor reduction and NSF/ANSI 372 for lead-free material, and is BPA-free.
- 0.5 micron coconut shell carbon filtration
- NSF/ANSI 42 and 372 certified
- Replaces UKF8001, Filter 4, EDR4RXD1, Puriclean II
- BPA-free, 3-pack
Who it's for
For owners of Whirlpool, Bosch or Kenmore refrigerators that currently use a UKF8001, Filter 4, EDR4RXD1 or Puriclean II filter and want a certified replacement three-pack. Not relevant to refrigerators outside that compatible parts list.
Pros and cons
- NSF/ANSI 42 and 372 certified
- Replaces UKF8001, Filter 4 and Puriclean II parts
- Three-pack covers a year or more of changes
- Only fits models on the listed compatibility list
Performance notes
The filter uses coconut shell carbon rated to 0.5 microns, which the listing states is finer than the 1-micron rating on some competing filters, and it carries NSF/ANSI 42 certification for reducing chlorine taste and odor plus NSF/ANSI 372 for lead-free construction. Fit is specific: it's built to replace UKF8001 and its part-number variants, and the listing names individual Whirlpool, Bosch and Kenmore refrigerator models it's designed for, so checking your fridge's model number against that list before buying matters more than any other spec.
