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
The Crystala CF9 comes as a 4-pack, which brings the per-unit cost down compared to buying filters one at a time. At $39.99 for the set, you get roughly $10 per filter, making it one of the more affordable ways to stay on a regular replacement schedule for compatible GE models.
The filter carries an NSF certification, which indicates independent testing against a recognized standard for drinking water treatment components. Crystala lists compatibility with GE GNE27JGMWW, so buyers should verify their specific fridge model before ordering. The plastic construction is typical for inline refrigerator filters of this style.
With 151 ratings averaging 4.5 stars, the CF9 has a small but generally positive review base. Most buyers note straightforward installation and no issues with fit on the listed GE models. The main limitation is that published flow rate and contaminant reduction data are not available in the listing.

Performance notes
The CF9 is NSF-certified, meaning it meets independently verified standards for water filter components. Because no specific purification method, capacity, or contaminant reduction data is listed, it is not possible to compare its filtration performance directly against other filters on numeric grounds. Buyers should treat the NSF certification as a baseline quality marker and confirm GE GNE27JGMWW compatibility before purchase.
What buyers say
At 4.5 stars from 151 reviewers, the CF9 earns solid marks for a filter in this category. The review count is modest, which limits how much weight any individual pattern carries, but the above-average rating suggests most buyers are satisfied with fit and function on their GE units.

Frequently asked questions
How many filters come in the Crystala CF9 pack?
The CF9 is sold as a 4-pack, priced at $39.99 total. That works out to roughly $10 per filter, which is on the lower end for NSF-certified refrigerator replacements. Stocking four at once also means fewer reorder trips if you change filters every six months.
What refrigerator models does the CF9 fit?
Crystala lists compatibility with the GE GNE27JGMWW. Before ordering, cross-reference that model number with your fridge's owner manual or the filter compartment label. If your specific GE model is not confirmed, contact Crystala or check their compatibility chart to avoid a mismatch.
Is the Crystala CF9 NSF certified?
Yes, the CF9 carries an NSF certification. NSF certification means the product has been tested by an independent organization against established standards for drinking water treatment components. It does not, on its own, tell you which specific contaminants the filter is certified to reduce, so reviewing any available spec sheet is worthwhile if you have particular water quality concerns.
