How We Evaluate Every Product
Every product we review is measured against the same core criteria — the things that actually determine whether it works for you.
Contaminant Removal
We verify which contaminants each filter actually removes — PFAS, lead, chlorine, VOCs, bacteria — against NSF/ANSI certifications and independent lab data.
Flow Rate & Capacity
A filter that slows your tap to a trickle gets abandoned. We measure real-world flow rates and filter lifespan so you know what to expect in daily use.
Installation & Maintenance
How hard is it to install? How often do you replace filters? We evaluate the full ownership experience — not just what the box says.
Total Cost of Ownership
The purchase price is only the beginning. We calculate replacement filter costs over 1, 3, and 5 years so you can compare the true cost of clean water.
