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 AQF-FF45 from Aqua Crest comes in a four-pack at $36.99, putting each filter at roughly $9.25. That price is competitive for an NSF-certified product, and the review base of over 3,800 ratings at 4.7 stars is one of the more credible signals in this category.
The filter measures 4.72 x 4.72 x 8.07 inches, a squat cylindrical form factor typical of twist-in refrigerator filters. Aqua Crest is a well-established third-party filter brand with a wide compatibility catalog, so checking the product listing against your fridge model is the main pre-purchase step.
Capacity and purification method are not published in the available specs. Buyers should plan replacement intervals based on the manufacturer's guidance on the product listing and local water quality conditions rather than a stated gallon limit.
