The Omnipure ELF 10M-P is the mid-size ELF-Series carbon block cartridge with integrated phosphate scale reduction — sized between the standard 10-inch cartridges and the extra-large ELF XL versions. The 4 by 12.5 inch form factor delivers approximately 50% more filtration capacity than standard 10-inch cartridges while fitting in installations where the ELF XL’s 15-inch length wouldn’t.
10 micron particulate filtration handles the sediment and rust common in municipal and well-water supplies, while the integrated phosphate scale reduction protects downstream equipment from lime buildup. The combination matters in commercial and high-end residential installations where you want longer cartridge service life without committing to the bulkiest ELF XL housing.
For coffee shops, restaurants, and high-volume residential installations running the ELF housing format, this is the mid-tier cartridge in the lineup. Made by Omnipure in Caldwell, Idaho. The ELF housing accepts the matching 4 by 12.5 inch ELF-series replacement cartridges.
