Home Master HMF3SdgFeC 3-Stage Whole House Sediment, Iron and Carbon Filter review
Iron and manganese filter. Plumber recommended if you are not comfortable with this install. Skill and code, not a preference. No third-party certification on record. Claims below are manufacturer-reported.
What it removes
| Contaminant | Evidence | Stated reduction | Scope |
|---|---|---|---|
| Iron | Manufacturer-reported | not stated | |
| Manganese | Manufacturer-reported | not stated |
Certified is an NSF, WQA, or IAPMO listing for that claim. Manufacturer-reported reduction for iron. Not NSF-certified for iron.
Iron and manganese staining at the main.
Install upstream of a softener so iron does not foul the resin; built-in 4-layer sediment stage serves as the prefilter.
20 x 4.5 in housings, 1 in ports, heavy steel bracket. Stage 1 multi-gradient sediment 25 to 1 micron, stage 2 radial-flow iron reduction cartridge, stage 3 radial-flow GAC carbon (100,000 gal). Manufacturer limits: iron < 3 ppm (iron, manganese, H2S up to 3 ppm combined), manganese < 1 ppm, pH > 7.0, no iron bacteria, not for chlorinated city water; up to 15 GPM; up to 95% VOCs/TOCs/herbicides/pesticides/iron/sediment. Iron stage life varies with load. Replacement set CsetBB3SmgFeC $265.25 on Amazon -> annual est. $265. Manufacturer page says 'NSF-42 certified' but Home Master is not in NSF's listing database (likely component-level); not recorded as a certification. Manufacturer list price $550-579.
