What this solution is
Start from your water report, not from a product list. This guide maps each documented concern to the treatment capability that addresses it, then to the installation formats that fit your household.
When it makes sense
Potential fit
- Anyone starting from a water report
Not the right tool for
- Private wells without a lab test
How it works
- 1
Find your city report and note the documented concerns.
- 2
Match each concern to a certified treatment capability (for example NSF/ANSI 53 for lead, 58 for RO).
- 3
Choose the installation format that fits: pitcher, faucet, countertop, under-sink or whole-house.
Models with a matching claim
Products appear only after the capability and certification checks above. Confirm the current certification listing and capacity for your own water before buying.
No product is recommended for this solution guide: the published findings do not document a concern that a certified filter claim addresses.
Sources and methodology
This solution guide describes treatment capability, not local water quality. PurityMap keeps local findings on water-system reports and matches products only after a documented concern and relevant certified claim align.
