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.

Overview
The GF-34 is a Glacier Fresh aftermarket replacement filter using activated carbon media, available as a 2-pack. At $53.99 for two cartridges, the per-unit cost is roughly $27, which sits on the higher end of aftermarket pricing. The filter is 9.73 x 2.33 x 2.33 inches, a standard inline cartridge profile.
Glacier Fresh carries NSF certification on this model. Activated carbon in this form factor is designed to reduce chlorine taste and odor, and the elongated 9.73-inch length suggests a larger carbon bed compared to shorter inline cartridges, which may affect service life though no rated capacity is listed.
With 267 reviews at 4.6 stars, the GF-34 is in an earlier stage of market feedback compared to more established models with thousands of reviews. The 4.6-star average is consistent with other well-performing Glacier Fresh products, but buyers should weight this with the smaller sample size in mind.

- Activated carbon design is appropriate for chlorine taste and odor reduction

Performance notes
The GF-34 uses activated carbon media in a 9.73 x 2.33 x 2.33-inch cartridge. Activated carbon is designed to reduce chlorine taste and odor and some aesthetic impurities. NSF certification is noted but the specific standard number is not differentiated in the available listing data. No gallon capacity, flow rate, or service life specification was available. The longer 9.73-inch body compared to typical 6-to-8-inch inline refrigerator filters may indicate a larger carbon mass per cartridge.
What buyers say
With 267 reviews averaging 4.6 stars, buyer sentiment for the GF-34 is positive but the sample is still limited. A review count in this range makes it harder to draw strong conclusions about edge cases like fitment on less common refrigerator models or performance in higher-mineral water conditions. No bought-last-month data was available.

Frequently asked questions
Why does the GF-34 cost more than other aftermarket filters?
At $53.99 for a 2-pack, the GF-34 is priced higher per cartridge than many competing 3-pack options that sell for under $30. This could reflect the longer 9.73-inch form factor, specific compatibility requirements, or simply brand and market positioning. If per-filter cost is a priority, comparing the GF-34 against a 3-pack alternative for your refrigerator model may be worthwhile.
What does the GF-34 filter reduce?
The GF-34 uses activated carbon and carries NSF certification. Activated carbon in refrigerator filters is primarily designed to reduce chlorine taste and odor and certain aesthetic impurities. The specific NSF standard number was not differentiated in the available listing data, so for precise contaminant reduction claims, check the full product documentation or the Glacier Fresh website.
Is 267 reviews enough to trust the 4.6-star rating?
A 4.6-star average from 267 reviews is a positive signal, but it carries more statistical uncertainty than a product with thousands of reviews. Patterns that emerge from 5,000 reviews tend to be more predictive of typical experience than those from 267. The 4.6 rating is consistent with other Glacier Fresh products that have larger review bases, which provides some corroborating context.
