Not sure which filter set you need? Check out our FAQ page or reach out to us. We're always happy to help!

Note: Wellsys® models use two different filter styles. Some systems use standard inline filters (compatible with our replacements), while others use proprietary twist-on cartridges (not compatible with our replacements). Model name, number, or age alone isn’t a reliable indicator of filter type.

Visit our FAQ page for some example photos of compatible and incompatible filters.

If you’re unsure which style your system uses, please contact us. We are always happy to confirm compatibility. We may request your model number and photos of your current filters.

*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.
