A 4.5-star average from over 6,300 reviews is a solid result, though slightly below the 4.6 to 4.8 range common among top-rated alternatives. The high monthly sales volume of around 1,000 units confirms this is an active, well-adopted product rather than a slow-moving listing.

Frequently asked questions
What does NSF 42 certification cover for the FL-RF46?
NSF 42 certification means the filter has been tested and certified to reduce aesthetic impurities from drinking water, primarily chlorine taste and odor. It does not cover health-effect contaminants such as lead, cysts, or pharmaceutical compounds. For those, look for NSF 53 or NSF 401 certified filters.
How does the FL-RF46 compare on price to other 3-packs?
At $24.99 for three filters, the per-filter cost is about $8.33, which is at the lower end of the certified aftermarket market. Some competing 3-packs are priced in the $26 to $37 range, so the FL-RF46 is among the more budget-friendly certified options available.
Is the 4.5-star rating a concern compared to 4.7 or 4.8-star competitors?
A 4.5-star rating is still a positive result overall, especially backed by over 6,300 reviews. The difference between 4.5 and 4.7 stars at this sample size typically reflects a small proportion of buyers who experienced compatibility or fit issues. If the filter fits your refrigerator model, the majority of buyers are satisfied with performance.
