Best UKF8001 Replacement, By Far
Reviewed in the United States on January 31, 2018
The OEM filters are pricey, but to me they're worth every penny. I have looked all around for any other alternative that is rated as highly as these for contaminant reduction and there are none. I cannot find a single filter that replaces UKF8001 that is both NSF/ANSI 42 and NSF/ANSI 53, let alone NSF/ANSI 401 as well! All the cheaper, non-OEM filters that I have seen are NSF 42 only, if certified at all. I don't see the point in wasting money on a cheap filter that may not actually be filtering anything instead of paying up for a filter that filters contaminants like Naproxen and DEET out of the water. Do yourself a favor: if you're actually trying to filter your water, get this filter. I've had 4 now, all worked perfectly.
