Overview
Fitting Sub-Zero's 4204490 and 4290510 water filter slots along with the 7007067 and 7042798 air cartridge, this Glacier Fresh combo pack is a twist-lock replacement for both parts at once. It's a compatible aftermarket part, not a Sub-Zero branded product.
The manufacturer's own disclosure states its NSF claims have not been independently tested or certified, which is worth knowing before comparing it to OEM Sub-Zero filters on paper. The twist-lock design mirrors the original fit, and reviewers back that up, but the fridge's digital display doesn't always recognize the aftermarket air cartridge for its reset countdown.
- Fits Sub-Zero 4204490 and 4290510 water filter systems
- Replaces 7007067 / 7042798 air purification cartridge
- Coconut shell carbon block, 0.5mm micro hole size
- Recommended 6-month air filter change interval
Who it's for
Works for owners of compatible Sub-Zero built-in refrigerator and freezer models who want a lower-cost pair of replacement filters. Not relevant to other refrigerator brands, since fit is specific to these Sub-Zero water and air filter housings.
What buyers say
From Amazon customer reviews.
Reviewers report both filters install easily and perform comparably to Sub-Zero's own parts at a lower price, with several noting the water filter resets manually without any issue. One reviewer flags that the fridge's digital display doesn't sense the Glacier air filter and keeps indicating it needs replacing even after a fresh cartridge is installed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Twist-lock design installs without tools
- Noticeably cheaper than Sub-Zero OEM filters
- Combo pack covers both water and air filtration
- NSF claims not independently tested, per the manufacturer's own disclosure
- Air filter may not register on the fridge's digital reset display
Performance notes
The water filter uses a coconut shell carbon block with a 0.5mm micro hole size for odor and taste reduction, twisting into place the same way as the OEM part without tools. The air cartridge is meant to be swapped roughly every six months to keep refrigerator odors down. The manufacturer states its NSF-related claims have not been independently tested or certified under that model number.
