About the tool
About FilterProof
A manual water-filter comparison that distinguishes confirmed compatibility, incompatibility, and unknown rows while estimating cartridge life and annualized cost.
What works here
Enter your own inputs, compare the calculated results, and export a report. You can save one input snapshot in this browser and import or export input files. Examples are illustrative and do not represent live prices, inventory, or customer records.
Clear limits
- There is no product catalog, retailer feed, affiliate link, or real-time price lookup. You supply every candidate row.
- Unknown means a required fact was not confirmed. It is never treated as compatible.
- Compatibility depends on the exact appliance model, installation geometry, certification, and manufacturer instructions. Confirm those outside this tool.
Privacy and access
The tool does not require an account or a paid subscription. Calculations, attachments, and exports stay in your browser. There are no active ads, affiliate redirects, or checkout integrations. Optional Cloudflare Web Analytics is loaded only after explicit consent.
