The Metpure Versatile MV4-ROLB is a 4-stage reverse osmosis system for clean, great-tasting drinking water under your sink. Its Lime (L) 100 GPD membrane is built for speed and flow, and quick-twist, color-coded filters make changes fast and mess-free.

The 4 stages

• R, Red sediment: removes sand, silt, dirt and rust. Up to 950 gal (3,600 L), about 6-12 months.
• O, Orange carbon block composite: reduces chlorine, odor and organic compounds, with secondary polypropylene sediment filtration that captures carbon fines. Up to 950 gal, about 6-12 months, while keeping chlorine reduction at 90% or more.
• L, Lime 100 GPD RO membrane: rejects up to 99% TDS under laboratory conditions. Replace when drinking-water TDS divided by feed-water TDS reaches 15%, usually every 2-5 years.
• B, Blue post GAC: reduces chlorine, odor and organic compounds. Up to 1,900 gal (7,200 L), about 12-24 months with an RO membrane (6-12 months without).

Filter lifespans were tested with municipal water at working flow rate and pressure range; actual life depends on usage and water quality.
