Overview
A Sub-Zero refrigerator is where this Glacier Fresh combo pack goes, with one cartridge for the water line and one for the air purification system. Activated carbon in the filter is listed as reducing chlorine.
Buying both cartridges together is the convenience, and the title cross-references the original and alternate part numbers. Fit depends on matching those numbers to your model. The listing does not describe the air cartridge in detail or give a replacement interval.
Who it's for
Owners of Sub-Zero refrigerators with the listed water and air filter numbers can stock both with one purchase. Owners of other brands should skip it, since the listing names Sub-Zero only.
Pros and cons
- Water and air cartridges together
- Activated carbon media
- Cross-references several part numbers
- NSF testing listed
- Included components list only the water filter
- Fit limited to Sub-Zero part numbers
- Replacement interval not listed
Performance notes
Water passes through activated carbon, which adsorbs chlorine and improves taste and odor. The air cartridge works in the air purification housing rather than on the water line. How long each lasts depends on water quality and usage.
