*Note: If you are transitioning from the original factory Crystal Quest water filters to our Raintree™ replacement filters, you will need to add our "no-tool fittings" and 3-4 feet of extra tubing to your order for the inital conversion as the fitting to tubing connection is a different style.
**If you have a Crystal Quest UF+RO cooler, you can use our filters (with the no-tool fittings), however, you should choose our Reverse Osmosis replacement filter set as we do not have a combination UF+RO filter set.
