The Omnipure OMB934-1M-P is a 9.75" x 2.75" carbon block filter cartridge that combines 1-micron sediment filtration with polyphosphate scale inhibition in a single drop-in replacement. Built entirely in Omnipure's facility using their proprietary block media, it fits standard 10" housings and removes chlorine, sediment, taste, and odor while protecting appliances from scale buildup.

COMPATIBILITY & APPLICATIONS
Where This Filter Works
The OMB934-1M-P fits any standard 10-inch filter housing with 2.5-inch diameter cartridge wells. It's commonly used as a pre-filter in reverse osmosis systems, inline for ice makers and coffee equipment, or in whole-house applications where chlorine removal and scale prevention are priorities. The polyphosphate additive is especially useful upstream of water heaters, dishwashers, and other appliances vulnerable to mineral scale. Compatible with Omnipure, Pentek, Culligan, and other brands using the 10" x 2.5" standard format.
💧 Pro Tip: The polyphosphate in this cartridge works by sequestering calcium and magnesium, not removing them. It keeps minerals suspended so they don't form scale, but doesn't soften water. If you need true hardness reduction, pair this with a salt-based softener or use a dedicated scale-reduction cartridge downstream.
