Question: are rpwf and rpwfe filters the same?
Answer: The RPWFE replaces the RPWF and is backward compatible for all models using the RPWF. Most new French-door models will start to use the RPWFE. Models that come with the RPWFE cannot use the RPWF. The RPWFE features the Advanced Filtration from the RPWF as well as being NSF certified to to reduce VOCs.
