Renée's Take · Jul 2026
How I Tested 4 Countertop Water Filters
I tested 4 countertop water filters from 3 brands across 9 safety checks, including PFAS Removal and Lead Removal. Every product was scored the same way: material safety first, then real-world performance and ease of use.
What I found: The top picks pass third-party safety verification and hold up in everyday use. The countertop water filters I left off had unverified material claims, missing certifications, or hidden tradeoffs that matter day to day.
