Detail 1: Filter and connection style

Three full-height Raintree™ filters and their push-fit connections installed vertically inside a water cooler

Confirm the connection style matches your system.Proprietary twist-on cartridges are not interchangeable with these filters. Look for:

  1. 1Push-fit connectors on both ends of every filter
  2. 21/4 inch tubing connects to both ends of every filter

*If you don’t see push-fit connectors and 1/4 inch tubing at both ends of every filter, or if you’re unsure, please reach out before ordering. *The tubing between filters may be longer or shorter than shown; tubing length does not affect compatibility.
