Under-sink filters for lead

Under-sink products compared against lead, with each product’s certification evidence, what it isn’t suited to, and why it is listed.

How products are ordered

A product counts as a match for a concern only when a current certification record covers it; every concern stays listed with its own state. The order is matches first, then the number of concerns matched, then name. Price never affects the order.
