Overview
The Kenmore 350 is a freestanding ion exchange water softener with a 0.83 cubic foot resin bed housed in an ABS cabinet, built for households wanting whole-home hardness reduction without a separate brine tank.
The 350 designation covers Kenmore's standalone softener line, pairing a resin tank and brine reservoir inside one 48 inch shell rather than two connected units. Confirm your water's hardness level fits within a 0.83 cubic foot resin bed before choosing this over a larger series.
- 0.83 cubic foot ion exchange resin bed
- Freestanding ABS cabinet, 20.5 x 15 x 48 in
- 80 lb shipping weight
- Softens water through ion exchange regeneration
Who it's for
Households on moderately hard municipal or well water wanting a single-cabinet softener. Not suited to very hard water or large multi-bathroom homes needing a bigger resin bed.
Pros and cons
- Freestanding cabinet needs no separate brine tank
- Ion exchange handles standard water hardness
- 80 lb unit is not a small installation
- 0.83 cubic foot resin bed suits moderate demand only
Performance notes
Ion exchange softeners swap calcium and magnesium ions for sodium or potassium held in the resin bed, then regenerate that resin periodically using brine. The 0.83 cubic foot bed size sets the practical limit on how much hard water it treats between regenerations.
