In an unusual turn for Wirecutter, we tested only one other model for this guide, the Brita Complete Faucet Filtration System. That’s because Pur and Brita offer the only faucet-mounted filters we’ve found that are certified by the American National Standards Institute and NSF International and are widely available in North America.

The Pur Advanced faucet-mounted filter is ANSI/NSF certified for 71 contaminants, including lead, mercury, many pesticides and industrial chemicals, and 12 “emerging compounds” (PDF) that are increasingly found in US drinking-water supplies. That puts it well ahead of Brita’s faucet filters, which are certified for 56 contaminants. The Pur filter is easy to install on a standard faucet (but be aware that no faucet-mounted filters will work on those with integrated pull-out sprayers). Over months of heavy testing, the Pur Advanced proved durable, never developing leaks or other hardware problems, and its built-in flow meter and indicator light automatically signal when it’s time to replace the filter cartridge. Finally, since the Pur Advanced system is available in multiple finishes, you have a better chance of matching it with your kitchen’s hardware than you do the Brita.
