Overview
The Filterlogic FL-RF46 is an NSF 42 certified replacement water filter sold in a three-pack, each cartridge under a pound. Its bought-past-month figure of around 1000 units points to it being a common reorder rather than a niche part.
NSF 42 covers reduction of aesthetic impurities such as chlorine taste and odor rather than health-related contaminants, which is the scope this cartridge is certified for. The listing does not name a specific system or OEM part number this replaces, so fit should be confirmed against your existing filter housing before ordering.
- NSF 42 certification
- Three filters per pack
- Under 1 lb per cartridge
- Dimensions about 5.71 x 1.97 x 7.87 in
Who it's for
Fits anyone who has confirmed this cartridge matches their existing filter housing and wants a three-pack on hand for future changes. Not the right pick if you're unsure of your system's required filter and have no OEM part number to compare against.
Strengths and trade-offs
Drawn from this product's published specifications.

- No stated OEM cross-reference or compatibility list
- NSF 42 doesn't cover health-related contaminants
- Filter only, no housing or dispenser included
Performance notes
Each cartridge is certified under NSF 42 for aesthetic impurity reduction, meaning it targets chlorine taste and odor as water passes through rather than broader health-contaminant filtering.
