Filter Specifications
The following table describes the available filters.
Filter Purpose
61AAN
Removes iron and iron algae and bacteria. Reduces manganese. Also removes up to 5 ppm Hydrogen
Sulfide with the presence of 2 ppm iron. For regeneration frequency, see 61AAN WaterMax

Sizing Formula for this model.
61AAE-BWO
Removes tastes, odors and will reduce most man-made pollutants. Backwash every 3 days or as
needed. Warning: Must not be backwashed for 24 hours after installation.
61AAR-BWO
Removes suspended matter (turbidity) from water down to the 20–40 micron range. Backwash every
3 days or as needed.
61AAS-BWO
Will raise the pH of most low pH water. The mineral media must be replenished periodically to
maintain optimum bed depth for effective correction. Backwash every 2 days to prevent solidification of
mineral media.
61AAF-BWO
Removes suspended matter (turbidity) from water down to nominal 20 microns. Backwash every
3 days or as needed.
