Instructions for Regenerating Nitrate Removal Filter Cartridges:

To regenerate: place a second filter housing containing a filter cartridge full of softener salt before the filter housing containing the Nitrate Removal filter so that the water coming out of the salt filter will go to the Nitrate Removal filter.

Run the water very slowly (approx. 0.25 GPM for a 10" filter) through the cartridges until the salt is gone.

Each time the nitrate removal filter is regenerated, approximately 80% of the capacity is restored.

1st regeneration: 80% original capacity for nitrate removal
2nd regeneration: 64% original capacity for nitrate removal
3rd regeneration: 51% original capacity for nitrate removal
4th regeneration: 40% original capacity for nitrate removal
(and so on)

We do not recommend regenerating the nitrate removal filters more than four times.
