Gravity & Carbon Units
No power, no plumbing, no problem
Gravity-fed systems and high-performance pitchers need no electricity or plumbing — water simply drips through dense filter elements. They're the go-to for emergency preparedness, travel, and budget-conscious households that still want strong contaminant reduction.

How to Choose: Gravity & Carbon Buyer's Guide
Element quality is everything
The filter elements (not the housing) do the work. Premium carbon-composite elements last 3,000–6,000 gallons and reduce lead, chlorine, VOCs, and more.
Throughput for your household
Gravity is slow. A two-element system serves 1–2 people comfortably; add elements or choose a larger chamber for a family.
Published test data
Claims vary widely in this category. Favor brands that publish third-party lab results against NSF/ANSI standards.
