Compatible Sub-Zero Models

The Swift Green SGF-ZS48 filter cartridge fits Sub-Zero Pro 48 refrigerators and replaces part numbers 4204496, 4290510, 4204490 and 4609910000. It also cross-references the EcoAqua EWF-8003A cartridge. The pack contains one white carbon-block filter made in the USA.

Contaminant Reduction

The carbon-block membrane reduces volatile organic compounds, chlorine taste and odour, lead, cysts, mercury, asbestos and other listed contaminants. Flow rate remains fast enough for daily dispensing without noticeable pressure drop. No tools are required for the quarter-turn installation.

Build and Daily Use

The precision-moulded housing seats securely in the Pro 48 filter housing to prevent leaks during normal operation. Cartridge life follows the refrigerator manufacturer’s recommended replacement interval. White finish matches the original equipment appearance inside the appliance.

Questions about this item

How do I install the SGF-ZS48 cartridge in my Sub-Zero Pro 48 and what step causes leaks?

Push the cartridge straight into the housing until it clicks, then rotate a quarter-turn clockwise to lock; skipping the rotation leaves the seal loose and causes drips.

When should I replace the carbon-block filter in the SGF-ZS48?

Replace the cartridge every six months or after the rated capacity is reached, whichever comes first, to maintain reduction of VOCs, chlorine, lead, cysts, mercury and asbestos.

What limits the SGF-ZS48 during continuous high-volume dispensing?

The carbon-block media gradually saturates, so flow rate drops and contaminant reduction declines once the cartridge reaches its service life.
