No, the Annual WP-4V VOC Filter Kit is specifically designed for the 4-stage WP-4V system and is not compatible with the WP-5 system. The VOC filter included will not work with the WP-5. For your system, you need the annual pack shown below, which contains enough filters for two changes of the three vertical canisters and one inline final filter.
