No candidate is both compatible and fully confirmed. Unknown is not the same as compatible.

1 candidate(s) need an exact appliance-model or specification check.

Requirement set: appliance model "Example appliance model, verify from nameplate", current reference "CURRENT-VERIFY", connection "1/4 inch quick-connect".
Compatible means the row is marked exact appliance model match = yes and passes every entered connection, capacity, and life check.
Annualized cost = entered price × 12 ÷ entered life months. It excludes shipping, installation, taxes, and water-use changes.
This is a manual comparison, not a catalog. Confirm the exact appliance model and replacement reference in the manufacturer documentation before purchase.
A certification or source URL entered in a row is evidence for your review only; this tool does not fetch or verify it.

Know the boundaries

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.

Examples are illustrative. Results depend on the assumptions and measurements you enter.

Method, not guesswork

Start from the exact appliance model, then compare only facts you can support: connection, rated capacity, cartridge life, and a price you entered.

Common questions

What makes a candidate compatible?

The row must be marked as an exact appliance-model match and pass every entered connection, capacity, and life requirement.

How is annualized cost calculated?

Entered price is multiplied by 12 and divided by entered cartridge life in months.

Does the tool verify a candidate source URL?

No. It validates the URL format and keeps it with the row; the source and exact specifications still need your review.
