3,200 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
The Filterlogic FL-RF13 arrives as a single filter at $18.99, which is a practical price for buyers who prefer buying one at a time or want to test the fit before committing to a multi-pack. The NSF 42 and NSF 372 certifications cover reduction of aesthetic impurities and confirm lead-free materials, respectively.
The compact 3.46 x 3.46 x 5.43-inch form factor fits a common refrigerator filter housing configuration. The weight of 6.4 lb is higher than many comparable filters, which may simply reflect how the product was weighed or packaged. Buyers should confirm dimensions rather than rely on weight as a size indicator.
At 4.7 stars from more than 3,200 reviews, the FL-RF13 has demonstrated consistent buyer satisfaction. That review volume is well above average for a single-unit filter and supports confidence in fit and taste improvement performance.
Pros

- Accessible $18.99 single-pack price for buyers who prefer one at a time
- Compact form factor suitable for common filter housing types
Cons
- Single-unit format costs more per filter than multi-pack alternatives

- No capacity or filter life spec listed

Performance notes
NSF 42 certification covers reduction of aesthetic impurities including chlorine taste and odor. NSF 372 certification confirms the filter is made with lead-free materials, which is meaningful for households concerned about lead from plumbing rather than source water. No capacity figure in gallons is available, so the standard six-month replacement interval applies as a safe default.
What buyers say
Buyer feedback is consistently positive at 4.7 stars from over 3,200 ratings. This level of review volume for a single-unit filter indicates the FL-RF13 is widely purchased and used. The high average rating suggests fit and taste performance meet expectations for most compatible refrigerator owners.

Frequently asked questions
What does NSF 372 certification add beyond NSF 42?
NSF 372 specifically tests that the wetted materials in the filter are lead-free, meaning the filter itself will not introduce lead into the water. NSF 42 covers the filtration performance for aesthetic contaminants. Together they confirm the filter reduces chlorine taste and odor and does not contribute lead from its own materials.
Is $18.99 for a single filter a good value compared to three-pack options?
On a per-unit basis, a three-pack filter in this category often works out to $8 to $12 per filter, so the single FL-RF13 at $18.99 costs more per unit. The single-pack makes sense if you want to verify compatibility before buying in bulk, or if your consumption pattern means a multi-pack would expire before use.
