HydroAudit Puts Water Systems on the Bench

A testing-led review site for residential water softeners, filters, and reverse-osmosis systems, with certification checks and ten-year ownership-cost analysis.

Why it surfaced

HydroAudit says it buys every unit at retail, installs each on the same 1 gpm rig, and publishes measurements at four points over a 720-hour test. Its unusually explicit affiliate disclosure—including the claim that commissions do not affect rankings—gives the water-treatment buying guide a concrete editorial premise rather than another listicle-shaped sales funnel.
