Current implementation
Pages use semantic headings, landmarks, visible focus states, a skip link, labeled form controls, keyboard-operable search results, responsive tables and reduced-motion support.
Color is not the only indicator of evidence grade; letter grades and explanatory text remain visible.
Known limitations
External manufacturer pages and performance documents are outside our control. Some may have inaccessible product selectors or PDF documents. WaterFilterSpecs summarizes only the fields reviewed and links to the original evidence.
