🏠 Best for Renters

Glacier Fresh PC04

4.3/ 5 SLF Rating

Best Use Case

Which Is Right for You?

BOROUX Legacy

Best for: Families, Renters, and households wanting high-capacity gravity filtration without installation.

Consider if: Limited Counter Space, Avoid Plumbing, Renting

Glacier Fresh PC04

Best for: Best for renters, apartment dwellers and smaller households that want a substantial countertop filtration system without modifying plumbing. Its gravity-fed design is especially appealing for households concerned about lead, PFAS, Chlorine, taste and odor while still wanting a simple, electricity-free system.

Final Verdict

Our Recommendation

BOROUX Legacy

Strong premium choice for families and renters who prefer gravity filtration over plumbed or powered systems.

Glacier Fresh PC04

A particularly good fit for renters. The PC04 earns its place in the SLF database by combining no-installation convenience with better contaminant documentation than many gravity-fed systems. We would choose it primarily for lead, PFAS, chlorine and taste-and-odor concerns rather than for shoppers seeking the broadest possible contaminant removal.
