The Multi-Stage Advantage for Marathon Shores
Pre-Filtration - Polypropylene
Captures larger particles and helps protect downstream filters and appliances from early clogging—especially after storm-related line disturbance.
Copper / Zinc Redox & Bacteriostatic Media—helpful in salty, coastal air conditions.
A copper-zinc redox alloy that converts chlorine and precipitates dissolved heavy metals, while suppressing bacterial and algal growth inside the housing—helpful in the salty, coastal Keys air.
Fine Activated Carbon Block
Fine filtration plus activated carbon adsorption—the stage that handles chemicals, taste, odor and color.
<0.01 Micron Hollow-Fiber Barrier
The final barrier. Bundles of hollow fibers with pores under 0.01 microns let water through and keep larger contaminants out.
How It Works
Water from the Florida Keys Aqueduct enters the inlet manifold at up to 80 PSI.
Sediment, KDF-55 and 0.5-micron carbon strip particles, metals and chemicals in sequence—helpful with hard Keys water.
The hollow-fiber membrane holds back what’s left, and purified water flows to every tap at 15 GPM.

Clean water flows through hollow fibers; ultra-fine contaminants stay outside—great for Florida Keys homes on aqueduct water.
Contaminants Reduced
Conventional Whole-House RO (Marathon Shores)
This System - Reactive Osmosis (RO2)
Traditional RO vs. Reactive Osmosis in Marathon Shores
A traditional whole house reverse osmosis system and a Reactive Osmosis (RO2) system are both after the same result—reverse osmosis quality water at every tap in Marathon Shores. They get there very differently, and the difference is what you live with day to day.
Traditional Reverse Osmosis
Reactive Osmosis (RO2) for Marathon Shores
Reactive Osmosis (RO2) delivers reverse osmosis quality water at every tap in Marathon Shores without a tank or a pump. It is not a reverse osmosis membrane, so it does not lower dissolved salts or TDS the way a conventional RO system does—what it removes is everything particulate and biological, for the whole house, at full pressure.
Pure water isn’t a luxury in the Florida Keys. It’s a lifestyle.
Bottled water-quality water on tap,
in every room of your Marathon Shores home.
99.99% turbidity reduction means
clearer glasses, ice, and bathwater in Marathon.
99.99% bacteria removal—organisms
are blocked, not just treated for Marathon Shores homes.
Carbon-polished water for coffee, tea,
and all your favorite recipes in Marathon Shores.
Tankless design delivers 15 GPM
—ideal for busy Marathon Shores homes.
80,000 gallon capacity keeps
maintenance down to an annual service.
KDF-55 and 0.5-micron carbon reduce chlorine, byproducts, taste & odor at the main line—ideal for Florida Keys Aqueduct water.
The 5-micron pre-filter and membrane handle silt, rust, turbidity and biological contamination together.
Installed across South Florida and the Treasure Coast—usually in a single visit.
Conventional whole-house reverse osmosis has three well-known drawbacks: it needs a storage tank, it needs a booster pump, and it sends a large share of your water down the drain as brine—then delivers it slowly. Reactive Osmosis (RO2) takes a different route to the same result. A hollow-fiber membrane with pores at or under 0.01 microns physically blocks bacteria, cysts, colloids, microplastics and many viruses—contaminants no carbon filter reliably stops—while running tankless at 15 gallons per minute, ideal for Marathon Shores homes that want full-pressure water throughout. It's worth being clear about the tradeoff: RO2 is not a reverse osmosis membrane, and it won't lower dissolved salts or TDS the way a true RO system does. What it does remove is everything particulate and biological—especially important after Florida Keys storms and flooding can impact plumbing and water quality—and it does it for the whole house at full pressure.
Treated at the main line, so kitchen, bath, laundry, and ice maker all get the same water—everywhere in the house.
99.99% turbidity removal/reduction shows up first in your ice and drinking glasses.
KDF-55 redox media helps prevent hard-water scale buildup inside pipes, fixtures and appliances.
Sediment and hard-water scale don’t reach your water heater, dishwasher, or washing machine.
Chlorine reduction at the main line means softer-feeling water for skin, hair, and fabric in Marathon Shores.
80,000-gallon capacity and long-life media keep upkeep to a single annual visit.
Whole House Reverse Osmosis for Marathon Shores & the Florida Keys
Most homeowners in Marathon Shores searching for a whole-house reverse osmosis system are really searching for one thing: bottled-water quality at every tap, not just the one under the kitchen sink. Here’s how whole-home RO works, where it struggles in the Keys, and why Reactive Osmosis (RO2) is how we install it.
A whole-house reverse osmosis system treats water where it enters your Marathon Shores home—at the main line—so every fixture gets purified water: kitchen, bathrooms, laundry, ice maker, and outdoor spigots. That’s the difference from a point-of-use RO unit, which only purifies one faucet and leaves the rest of the house on untreated water.
A true reverse osmosis membrane produces water slowly and under pressure, so a whole house RO system has to bank it: a large pressurized storage tank, a booster pump to refill it, and a brine line that sends a significant share of your incoming water to the drain. In Marathon Shores and across the Florida Keys—where space is tight and you want dependable water even after storm season—run two showers and the dishwasher at once and you can outrun the tank. The equipment footprint, the wasted water, and the pump are three reasons most homeowners abandon the idea.
Reactive Osmosis reaches reverse osmosis quality water by filtration rather than by pressurized rejection—ideal for Marathon Shores and the Florida Keys. Multi-stage media—a 5-micron sediment pre-filter, KDF-55 copper-zinc redox alloy, and a 0.5-micron carbon block—handle sediment, chlorine, heavy metals, VOCs, taste and odor often associated with Florida Keys Aqueduct water. A hollow-fiber membrane with pores at or under 0.01 microns then blocks bacteria, cysts, colloids, microplastics and many viruses outright. No storage tank, no booster pump, no brine line, and 15 gallons per minute on demand.
Chlorine, chloramine byproducts, hydrogen sulfide, VOCs, pesticides and dissolved heavy metals such as lead, mercury, nickel and chromium are handled by the KDF-55 and carbon stages—great for Florida Keys Aqueduct-supplied water. Bacteria, cysts, microplastics, turbidity and fine suspended solids are blocked by the membrane. Dissolved salts and TDS are the honest exception—lowering those takes a true RO membrane, which is the tradeoff you make in exchange for losing the tank, the pump and the brine.
Whole home reverse osmosis systems commonly run several thousand dollars once the tank, pump, plumbing and labor are counted. Our complete whole-house Reactive Osmosis (RO2) system is $2,995 installed - regularly $5,000, so you save $2,005. That price includes the cartridge housings, manifold, membrane vessel, professional installation, a water test and a system check before we leave.
On Florida Keys Aqueduct water, the KDF-55 and carbon stages take on chlorine, disinfection byproducts, taste and odor at the main line. In Marathon Shores’ coastal, sea-air environment, these stages also help protect plumbing from buildup and corrosion-related debris. The 5-micron pre-filter and the membrane handle silt, rust, turbidity and biological contaminants together—especially helpful after hurricanes or flooding when water quality can change. We install whole-house reverse osmosis quality systems across Monroe County, including Marathon Shores, usually in a single visit.
