EDR4RXD1 filter: genuine vs replacement
Last checked October 28, 2026
Buy genuine
The genuine everydrop Filter 4 is listed to NSF/ANSI 42, 53 and 401 at the exact model level (NSF).
We found no replacement sold under the EDR4RXD1 number with a listing in the databases we searched.
Many replacements are sold as UKF8001 replacements rather than under the EDR4RXD1 number. We only compare filters sold under the genuine number or a number the maker lists for the same filter, so those are not compared here.
Verdict: buy genuine if you want every listed claim. There is no listed replacement to compare it with.

The genuine filter's NSF/ANSI 53 listing includes lead reduction.
