Not sure what's in your water? Get it tested first.
Before buying a filter, it helps to know exactly what you need to remove. A professional water test gives you a complete picture of your water quality, including contaminants that may not show up in EPA data (like private well water or pipe-specific issues like lead).

NSF Certification
We prioritise filters with NSF/ANSI certifications (Standards 42, 53, 58, 401, and P473 for PFAS). NSF certification means the filter has been independently tested by a third-party lab to verify its contaminant removal claims.
Independent Lab Testing
Beyond NSF, we look for filters that publish independent third-party lab results showing specific contaminant removal percentages. Transparency about testing methodology matters more than marketing claims.
Contaminant Removal Data
We match filters to specific contaminants. A filter that removes chlorine taste may not remove PFAS or lead. Our recommendations are based on what each filter actually removes, verified by test data, not just what the label suggests.
Total Cost of Ownership
The sticker price is only part of the cost. We factor in replacement filter costs, filter lifespan, and flow rate to give you a realistic picture of what each system will cost over time. A cheap pitcher with expensive filters may cost more than a pricier system in the long run.
