A filter cartridge includes a radio frequency identification, RFID, tag positioned on a casing. A compressed cellulose foam is positioned over the RFID tag on the casing. An impermeable material is positioned over the cellulose foam on the casing at an outer surface of the casing. The impermeable material defines a passage that extends through the impermeable material to the cellulose foam. The passage is configured such that water is flowable through the passage to the cellulose foam. The compressed cellulose foam is configured for wicking the water from the passage to the RFID tag.
