Including filter system and high-performance Copper filter.
Copper can enter household water when it leaches from plumbing materials like older copper pipes or brass fixtures. Conditions that promote corrosion — for example water that’s more acidic — make that process more likely and can raise copper at the tap. You might detect a metallic taste, see bluish-green staining around sinks or tubs, or notice water discoloring after it sits. Because levels can differ from faucet to faucet, Littman homeowners benefit from looking at their whole-house water, not just a single tap.
Though copper is a common metal, elevated amounts in drinking water deserve attention. Copper concentrations often fluctuate with usage patterns, temperature and how long water remains in pipes, so intermittent spikes can go unnoticed without testing. Knowing where the water is picking up copper — whether from the service line, supply, or interior plumbing — helps decide the right response. In Littman, pairing corrosion control with the appropriate filtration is usually the best way to keep copper out of your family’s glass.
To remove dissolved copper throughout the house, a whole-house reverse osmosis system is the most effective single-filter choice because its semipermeable membrane rejects metal ions. Unlike sediment or carbon-only filters, RO targets dissolved inorganics like copper rather than only improving taste and odor. When installed for Littman homes, it reduces copper at showers, kitchen sinks and bathroom faucets — not just at one point — and is a solid option whether copper is coming from the supply or from corrosion inside plumbing.
A whole-home RO installation typically includes prefiltration to protect the membrane from chlorine, sediment and scale that can shorten its life. Because reverse osmosis produces a concentrate stream, correct sizing and professional installation are important to preserve household flow and convenience. If copper is mainly picked up from interior plumbing, combining the RO system with measures that reduce corrosivity will give steadier results.
