1,700 owner reviews, more than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
At $122.99 for a four-pack, the GF-009X runs about $30.75 per filter, placing it noticeably above the typical aftermarket replacement price. The carbon fiber material is the differentiator here. Carbon fiber filter media can offer a different surface area and flow dynamic compared to standard granular activated carbon, though exact performance figures require checking the manufacturer's product listing.
The filter measures 9.96 x 1.73 x 1.73 inches and weighs just under one pound for the pack. That slender cylindrical form suggests an inline or twist-in installation. NSF certification provides independent validation of its filtering claims.
With 1,700 reviews at 4.5 stars, buyer satisfaction is solid. The main questions at this price are whether your refrigerator is compatible and whether the carbon fiber construction offers a meaningful advantage for your specific water quality situation.
Pros

Performance notes
The GF-009X uses carbon fiber as its filter material, which differs from the standard activated carbon block or granular activated carbon found in most replacement filters. NSF certification confirms independent testing against published standards. Dimensions of 9.96 x 1.73 x 1.73 inches and a weight under one pound indicate a lightweight inline-style filter. Without a stated capacity, replacement timing should follow the manufacturer's published guidance.
What buyers say
1,700 ratings at 4.5 stars is a healthy endorsement. The score holds up well given the elevated price point, suggesting that buyers who confirmed compatibility were generally satisfied with fit and performance.

Frequently asked questions
What makes the Glacier Fresh GF-009X different from standard carbon filters?
The GF-009X uses carbon fiber as its filter material rather than the granular activated carbon or carbon block found in most replacement filters. Carbon fiber offers a distinct surface structure, though for specific performance comparisons you should review the manufacturer's product page and the applicable NSF certification standard.
Why does the GF-009X four-pack cost more than comparable aftermarket filters?
The primary factor is the carbon fiber construction, which is a less common and typically higher-cost material than standard activated carbon. At $122.99 for four filters, the per-filter cost is around $30.75. Whether that premium is worth it depends on your water quality priorities and whether your refrigerator requires this specific form factor.
Is the Glacier Fresh GF-009X NSF certified?
Yes, the GF-009X carries NSF certification. This means it has been independently tested against NSF/ANSI standards. Check the product listing for the specific standard number to see which impurities or aesthetic concerns the certification addresses.
