Filters, checked against their listings.
Every claim here comes from a certifier’s own listing, linked and dated. What the box says, and what it costs over five years, are kept separate from what was certified.

Five-year cost for a household of 3 drinking 1 gallon each a day, at the makers’ list prices. “Replaced” is how often each filter runs out at that rate, by the maker’s gallon or month rating, whichever comes first. A filter rated for few gallons runs out fast, which is why a cheap pitcher can cost the most. “Incomplete” means a part due in those five years has no published price. Run your own numbers.
