Water Filter for the GE PSS26NGSBBB (MWF)

PSS26NGSBBB specifics — where the filter actually lives

Where the filter actually lives: low on the fresh-food side or behind the base grille in most side-by-side layouts, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically it is a quarter-turn twist-in seat: no tools, no housing removal, and the cartridge indexes in only one orientation despite looking symmetric.

Two quirks worth knowing before you order: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. Read the prefix and the maintenance writes itself: GE uses it across the Profile side-by-side range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. That BB suffix is trim-level shorthand. GE kept the MWF bay common to every finish in the line.

PSS vs GSS — what the prefix tells you

Same parts shelf, two cabinet missions — The Profile side-by-side/side-by-side split tracks the PSS/GSS prefixes — cartridge fit follows the water path, not the label on the door. the 26 cu ft figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does.

Swap it in 5 minutes

• Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
• Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
• Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

What this filter takes out of your water
