Score Breakdown

Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Tested and certified by NSF International against NSF/ANSI Standard 42 for chlorine, taste and odor reduction, and NSF/ANSI 372 for lead-free material.
Uses premium natural coconut activated carbon block with up to 97.2% chlorine reduction; also reduces sediment, large particles, rust, taste and odor.
Replace every 3 months; actual timing may vary based on local water quality.
Designed for high-efficiency filtration without waiting for filtered water to pass.
Fits PUR Plus and PUR RF-9999 style faucet filters; works with PFM100B, PFM450S, FM-3333, FM-9400B and many more.
Design and Build Quality
The filter is a drop-in replacement made to mimic the fit of the original PUR RF-9999 style filter. The listing notes packaging may vary during a transition period, but product quality and compatibility stay the same.
The 2-pack includes blue colored filters, and the manufacturer states the filter should be soaked in clean tap water for 3 minutes before use to flush bubbles and activate the media.
Performance in Everyday Use
According to the listing, the coconut activated carbon block reduces chlorine by up to 97.2% and also helps with sediment, large particles, rust, taste and odor. Flow is described as fast enough to avoid waiting for filtered water.
A real limitation is that this filter cannot reduce TDS. It also should be replaced every 3 months, though actual life may vary with water quality.
