These water filters & treatments have no maker-published weight on record, so they are not ranked by weight.
Replacement cartridges, maintenance kits, adapters and hoses are listed, not ranked. Squeeze, bottle and in-line filters, gravity filters and pump filters are each ranked among their own kind.
Weights and prices are the manufacturer's published figures as recorded in the RidgeNote register; each product page shows the source and the date read where one is recorded. Percentiles count only models with a published figure; ties count neither way. Price is the maker's list price; a retailer's current price is never used. The register is re-read on a schedule, so this page reflects the catalogue as of its last build.
