RainTree™ Pre Carbon Filter

The Raintree™ Pre Carbon filter removes contaminants by means of adsorption. Particles in the water adhere to the surface of the filter material, trapping impurities such as chlorine, VOC’s, bad taste and odor.
The Pre Carbon filter also serves the important purpose of protecting and extending the life of the UltraFilter (UF) Membrane or the Reverse Osmosis (RO) Membrane that follows.

*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.
