WaterChef SF-7C-ECO Low-Flow Shower Filtration System
The 1.8 GPM version of the SF-7C, and the only one sold in California and other low-flow states.
$88
Usability
For anyone in a low-flow state this is not a choice between two shower filters, it is the only WaterChef shower filter available. The certification is identical to the standard SF-7C, with the same IAPMO listing to NSF/ANSI 177 and the same 96.6 percent chlorine reduction across 10,000 gallons, so nothing is lost on filtration. What is traded is spray force: 1.8 gallons per minute against an unpublished but higher figure on the standard model. Cartridge life is unchanged at roughly six months, and chlorine remains the only certified claim, so this does nothing for lead, hardness or anything dissolved. Priced the same as the standard model at $87.95, it is the sensible default even outside regulated states for anyone who cares about water use. The buyer who wants maximum pressure and lives somewhere it is legal should take the standard SF-7C instead.

The WaterChef SF-7C-ECO is the 1.8 gallon per minute version of the SF-7C, built to meet the showerhead flow limits in California, Washington, Hawaii, Oregon, New York and other regulated states.
