Filter Sets

Filters should be changed once a year, we suggest the filter life can be extended with a watermax to 18 months.

If you let the filters go too long on a chlorinated water supply it could ruin the membrane.

Filters should be changed immediately if you notice the water doesn't taste right.

Call our service department to make sure you get the correct filter set for your model.

(800) 549-0038

When changing your filters make sure you turn off both the supply line and the tank shut off valve.

Make sure to read the complete filter change procedure before attempting to change your filters.
