The F.SET.SS-2.5 is the annual replacement cartridge for the Essential Max Flow SS-2.5 under-sink system from Environmental Water Systems. It keeps the 2.5 GPM flow and uses a 1 micron carbon block to reduce chlorine, chloramine, VOCs, THMs and other contaminants.
The media is a 1 micron extruded carbon block of activated matrix carbon, FDA compliant and certified to NSF/ANSI Standard 401. It also targets pesticides, herbicides, pharmaceutical residues and obesogens. The white housing is recyclable virgin polypropylene, free of BPA and phthalates.
Swapping cartridges is a twist-and-click job done about once a year; actual life depends on local water and usage, and fine sediment or microplastics can shorten it. It operates from 10 to 125 psi and 35 to 100 F, measures 4 x 16 in. and is offered in several pack quantities.
