Start with the place where you want to treat water, then compare the flow, maintenance, space, and verified reduction claims that matter for your household.
Drinking-water filters
- Pitcher filters — portable, simple, and limited by batch capacity.
- Faucet-mount filters — convenient at one tap, with compatibility and flow trade-offs.
- Under-sink filters — higher capacity with installation and cartridge-planning needs.
- Refrigerator and ice filters — model-specific compatibility and replacement guidance.
- Reverse osmosis — broad reduction potential with storage, wastewater, and maintenance considerations.
Whole-home and shower treatment
- Whole-house filters — point-of-entry systems that must match household flow and treatment goals.
- Shower filters — focused guidance on media, claims, fit, and realistic expectations.
Choose with evidence
Use your water report or an appropriate test to define the problem before choosing equipment. Verify certification for the exact model and reduction claim, and include replacement cost and maintenance in the decision.
