Including filter system and high-performance Sodium Chloride (Salt) filter.
Sodium chloride, most commonly called salt, can end up in household water for several reasons: natural presence in the source, groundwater influence, or from certain treatment and regeneration processes. In Key West, where coastal conditions and salt air are part of everyday life, even modest salt in water can make it taste brackish and leave you unsure about drinking or cooking with it. Homeowners watching sodium intake often find it especially concerning because dissolved salt is invisible in a glass.
Elevated salt changes how water acts around the house — from a persistent flavor in coffee, tea and ice to a dull, hard-to-remove film on fixtures and glass that can accelerate corrosion in seaside homes. Because sodium chloride dissolves completely, ordinary sediment filters and boiling won’t remove it. The right first move is a water test to determine whether the source is municipal supply, a water softener backwash, or another local influence in neighborhoods like Old Town or New Town.
When the goal is removing dissolved sodium chloride, the most effective single-filter option is a reverse osmosis system. RO uses a semi-permeable membrane to separate dissolved salts from water, unlike carbon or sediment filters that mainly address particles, chlorine and odors. This is the same core technology used for desalination and reducing total dissolved solids, so when salt is the primary concern, selecting the appropriate RO membrane and system configuration is what matters most.
For whole-house protection in Key West, reverse osmosis is usually set up as a dedicated system with prefiltration to shield the membrane and maintain performance. A pre-sediment filter prevents fouling and a carbon prefilter cuts chlorine that can shorten membrane life when present. Because RO produces both a purified stream and a rinse stream, proper sizing for daily household demand is important. Mr. Pure Water can test your water, identify salt sources affected by coastal conditions, and design a whole-house RO solution suited to your home and lifestyle.
