PUR PLUS FM2100B Faucet Mount Filter vs PUR Faucet Mount Water Filter FM-3333B

Both are PUR faucet mounts certified to reduce 70 contaminants, including lead, and both use the same RF-9999/RF-3375 replacement filters, so water quality is effectively equal. The FM2100B is the newer Mineral Core model in black with a filter change light; the FM-3333B is the long-running white vertical mount with a large owner base and a 4.4 rating across thousands of reviews. Pick on color, mounting style and filter-change indicator, not on filtration.

• Choose the PUR PLUS FM2100B if you want the black Mineral Core model with a filter change light and the newer PUR design on your faucet.
• Choose the PUR FM-3333B if you want the proven white vertical mount with a long track record and thousands of owner ratings behind it.
